Question 1: Briefly explain the importance of each source of knowledge mentioned in study
guide by giving example.
Source of Knowledge
There is only one accepted source of new knowledge and that is empiricism. The others,
which include, authority, rational induction and intuition are accepted as useful sources of
Intuition-knowledge based on feelings, beliefs, or “gut instinct “Authority-knowledge
based on a “credible” sourceational-Inductive Argument-knowledge based on past research as
well as combining that knowledge with new knowledge to comply with our current problem.
Empericism-knowledge based on library research, forming a hypothesis, setting up an
experiment to test the hypothesis, collecting data, and then analyzing that data to statistically
make a conclusion on the research hypothesis. The only accepted source of knowledge in
modern scientific psychological research is empericism.
The sources of new knowledge are authority, intuition, scientific empiricism, and an
educated guess. Authority, intuition, and an educated guess are all sources of hypotheses, but
scientific empiricism is the only source of new knowledge.
Different sources of knowledge are things like what you feel is right (I think that toads give
you warts), what someone you think is right says is right (mom said that toads will give you
warts), things you’ve seen (my brother was playing with a toad and then he got a wart), things
you’ve tested (I had my brother play with the toad and my neighbor played with a lizard, and
only my brother got warts). All of these are sources of hypotheses, a way to come up with ideas
to test, but only the empirical research, testing, is an acceptable scientific source of knowledge.
There are generally four sources of knowledge; intuition, authority, rational induction, and
empiricism. Intuition is knowledge that is gained through a feeling or thought that might turn out
to be true. Authority is a source of knowledge that you gain from your parents, or a book that
tells you that this is the way things are and thats that. Rational induction is a source of
knowledge by reasoning and proofs. This type of knowledge comes about by supposing one
thing and then giving a proof of it, or any other way you want to do a proof. Empiricism is
knowledge gained through careful observation, manipulation of variables through the scientific
method, repeating research designs, and taking in data to interpet. Empiricism is the accepted
role of knowledge in psychological research because psychologists use statistics and believe in
probabilistic conclusion. That people behave generally in one way in most situations and using
statistics to decide if two variables are related. The others are not accepted sources of
psychological. Authority, intuition are not accepted sources of knowledge for psychological
research because they are not grounded in any source of statistics or observable facts. Rational
induction is not an accepted source of knowledge because it involves proof and certaintiy, which
psychologists do not go for.
Descriptive knowledge is useful in discriminating, measuring or defining different
behaviors or characteristics. Predictive knowledge is useful in determining a statistical
relationship between two behaviors or characteristics and whether they are related.
Understanding is useful in determining whether changes in one behavior or characteristic
influences changes in another behavior or characteristic. Descriptive knowledge is used in
attributive hypotheses and are accepted as sources of knowledge in defining behavior or
characteristics. Predictive knowledge is used in attributive hypotheses and is useful in
determining if there is a relationship between two behaviors or characteristics. Understanding is
used in causal hypotheses and is useful in determining if there is probabalistic evidence that one
behavior or characteristic has an effect on another behavior or characteristic.
Empirical Research is a scientifically conducted study when yields results which are
cauasally interpretable. While rational induction is more logical thinking based on observation.
Observation is the process of objectivly viewing a situation and making inferences based therin.
Empirical Research is the only way to attain fact in modern scientific psychological research.
However, rational induction, observation and research are all valid ways to obtain a hypothesis.
The sources of new knowledge are rational induction, scientific empiricism, intuition and
authority. The only acceptable source of knowledge is scientific empiricism. Scientific
empiricism requires a research hypothesis be formed and tested, that the study is published in an
article to be scrutinized by other scientists. It also requires that the experiment is replicated
exactly as it was the first time to ensure the applicability of the findings to that particular set of
variables and subjects. Moreover Scientific empiricism dictates that similar studies with slight
variations on the first study be performed to confirm the generalizability of the results to similar
situations. All other sources of knowledge are acceptable for research hypotheses but are
questionable because they have not withstood the rigors of Scientific Empiricism.
The four sources of new knowledge include intuition (beliefs), authority (the influence of
someone with more experience), rational induction (relating to previous knowledge or tying two
ideas together to create a new one), and scientific empiricism (programmatic research). Scientific
empiricism is the only accepted source of new knowledge whereas intuition, authority, and
rational induction are accepted sources of hypotheses.
There are four sources of new knowledge: intuition, authority, rational-inductive, and
scientific empiricism. Intuition is based on what one thinks will happen, authority is based on
what one is told will happen, rational-inductive is based on a sort of cause and effect, that is, if
this, then that, and scientific empiricism is based on research. All four are good sources for a
research hypothesis, but scientific empiricism is the only accepted source of new scientific
The only source of new knowledge is scientific empiricism. There are other sources of
research hypotheses including intuition, which is something you have a feeling about, authority
which is taking the word of someone who was right in the past and knows what they are talking
about and rational inductive which says that one things leads to a second so it logically leads to a
third. There are four different types of knowlege. The first is Intuition, this is where you use what
you feel is the right answer. The second type of knowledge is authority, an example of this
would getting information from a professior who understands the knowledge. The third ttpe of
knowledge is Rational induction, here you are gathering past knowlegde and making knowlege
from that. The next type of knowlege is empirical, this is the only accetable type of knowledge
that can be useed in modern scientific psychological research.

Question 2: Define educational research in your own words. Justify that high quality
education system cannot be developed without the support of educational research.
Research is an in depth inquiry in to a problem which need an amicable solution. Every
invention in the world happens as a result of a scientific enquiry. See the example of Isaac
Newton when the apple falls on his head, he started the question with why? He searched for truth,
reason or discover to new knowledge. He applied commonsense in his enquiry. The continuous
search resulted in solving his problem. Finally he built a theory named as Gravitation force theory
with empirically proved body of knowledge. Hence research can be termed as the search for truth
or discovery of new things or builds body of knowledge regarding a phenomenon. Research is a
systematic, scientific, objective activity, which includes the collection relevant information, and
careful analysis of data, recording and reporting of valid conclusion, that may lead to creation of
new knowledge, development of theory, principles, and generalization. The developed theory,
Knowledge, principles or generalization may help the researcher or concerned authority to predict
occurrences of certain possible events and thereby make possible to ultimate control of unwanted
events. Research also means that the process of testing the validity of assumptions and formulated
hypotheses. When we come to the educational research it is the process of scientific inquiry to
solve the problems of educational sector of a country. It includes theoretical elaboration, quality
enhancement matters, policy draft and implication, classroom dimension and so forth. It involves
a continuous enquiry in search of knowledge, advancement, problem solving methodology and an
attempt to realize the truth from an objective point of view based on factual understanding and
Scope Educational Research
Education is considered as a vital tool for social as well as national development. It has
significant role in evaluating the human development of a country. When we assessing the
development of a person, society, community or a Nation, the educational attributes, such as
educational qualifications, number of educated person in the society or community, number of
educational institution in the state or country (elementary, secondary, higher, professional
educational sector) with respects to its population, rate of enrolment, retention, quality of
education provided, equity and equality for educational opportunity and so forth are considered as
the prime criteria for consideration. Hence every nation in the world has been giving emphasis to
the development educational sector of their country. Many innovative programmes and projects
are preparing by the policy makers as well as the academic bodies across the world to improve
their educational quantity as well as the quality. Crores of rupees are allocating in their budget for
implementing such planned programmes and project. In India the projects like District Primary
Education Programme (DPEP) , Sarva Siksha Abhiyan ( SSA), Area Intensive Programme (AIP) ,
Kasturba Gandhi Balika Vidhyalaya (KGBV), Rashtriya Madhyamik Siksha Abhiyan (RMSA),
Rashtriya Uchayistic Siksha Abhiyan (RUSA), Scheme for the Promotion of Quality Education in
Madrassas (SPQEM) are constituted and implemented to improve the standard of educational
sector of the country. Educational Researches are the main input as well as the output to bring
such change in the educational sector. Research findings identify the shortcomings, strength and
weakness of the educational sector of the country and it recommends implementing such and such
programme for the development of their educational sector. Educational research also helps to
evaluate the effectiveness as well as the impact of particular programmes and project which has
been undertaken by any governmental or non governmental agencies. Hence the breadth and
width of the educational research is unlimited. It has a scope to conduct research in any area of
education which has a chance to contribute knowledge for the development of education of a
society, community and Nation as well.
Purpose of Educational Research
The Educational research has enormous purposes. Some important purposes are presented as
• To identify truth regarding Enrolment, retention, dropout, quality of Education and so
• To build new knowledge regarding the methodology, pedagogy or other core subject
• Adding of existing stock of knowledge related to educational field
• To solve a problem related to classroom, institution, administrative level, policy level
• Invention of new teaching methods, curriculum transaction strategies, effective grouping
• technique and so forth
• Realizing the exact problem of educational sector
• Assess the Effect of New methodology of teaching
• Identify and assess the ICT enabled classroom and teaching
• To understand the teachers knowledge on latest evaluation techniques
• To identify the hindrances to achieve universalization of education
Characteristics of a good research
While analyzing the discussions of eminent educationalists and social scientists, we can
draw the following characteristics of a good research.
• 1. Research is directed towards the solution of a problem
• 2. Research is a continuous enquiry in search of knowledge
• 3. Research emphasis the development of generalization, principles, theories
• 4. Research is based upon observable experiences and empirical evidences
• 5. Research rejects revelation and dogmas as methods of establishing knowledge
• 6. Research employs in depth review of related literature
• 7. Research depends on valid and reliable data gathering procedure
• 8. Research demands accurate observations and descriptions
• 9. Research applies systematic and scientific procedure for the study
• 10. Research involves gathering of new data from first hand sources (primary) or existing
• data (secondary sources) for a new purposes
• 11. Research is based on carefully designed procedure with rigorous analysis
• 12. Research requires expertise
• 13. Research is a objective, logical process and eliminate personal bias
• 14. Research involve the quest for answer to unsolved problems
• 15. Possibility for Replication
• 16. Research is characterized by patient and unhurried activity
• 17. Research is carefully recorded and reported
• 18. Research sometimes required courage
• 19. Quantitative Research involves hypotheses testing using suitable statistical techniques
• 20. Qualitative Research involve objective thick description on thin data
Research is considered as process of searching for new knowledge. However, there will be
some administrative or academic urgency to deliberately repeat the previous study using same
procedure with another sample, in a new setting and at different time. This process is called
replication. It is the fusion of words of repetition and duplication. Replication is used to conform
the validity of the conclusion drawn by the previous studies which are under questioned from
different academic as well as political corner. Besides, replication is also necessary to understand
the trend, progress, development among generations in particular area. For example, a researcher
can replicate the study conducted by a researcher on the problem of ICT awareness and use
among the secondary school teachers. The result may evidence that what progress has been made
in the areas of ICT among the secondary school teachers while the time has passed after the
High quality education system cannot be developed without the support of
Increasing graduation rates and levels of educational attainment will accomplish little if
students do not learn something of lasting value. Yet federal efforts over the last several years
have focused much more on increasing the number of Americans who go to college than on
improving the education they receive once they get there.
By concentrating so heavily on graduation rates and attainment levels, policy makers are
ignoring danger signs that the amount that students learn in college may have declined over the
past few decades and could well continue to do so in the years to come. The reasons for concern
include: College students today seem to be spending much less time on their course work than their
predecessors did 50 years ago, and evidence of their abilities suggests that they are probably
learning less than students once did and quite possibly less than their counterparts in many other
advanced industrial countries.
Employers complain that many graduates they hire are deficient in basic skills such as
writing, problem solving and critical thinking that college leaders and their faculties consistently
rank among the most important goals of an undergraduate education.
Most of the millions of additional students needed to increase educational attainment levels
will come to campus poorly prepared for college work, creating a danger that higher graduation
rates will be achievable only by lowering academic standards.
More than two-thirds of college instructors today are not on the tenure track but are
lecturers serving on year-to-year contracts. Many of them are hired without undergoing the
vetting commonly used in appointing tenure-track professors. Studies indicate that extensive use
of such instructors may contribute to higher dropout rates and to grade inflation.
States have made substantial cuts in support per student over the past 30 years for public
colleges and community colleges. Research suggests that failing to increase appropriations to
keep pace with enrollment growth tends to reduce learning and even lower graduation rates.
While some college leaders are making serious efforts to improve the quality of teaching,
aiou solved assignments code 837
many others seem content with their existing programs. Although they recognize the existence of
problems affecting higher education as a whole, such as grade inflation or a decline in the rigor
of academic standards, few seem to believe that these difficulties exist on their own campus, or
they tend to attribute most of the difficulty to the poor preparation of students before they enroll.
Some Immediate Improvements
Many colleges provide a formidable array of courses, majors and extracurricular
opportunities, but firsthand accounts indicate that many undergraduates do not feel that the
material conveyed in their readings and lectures has much relevance to their lives. Such
sentiments suggest either that the courses do not in fact contribute much to the ultimate goals that
colleges claim to value or that instructors are not taking sufficient care to explain the larger aims
of their courses and why they should matter.
Other studies suggest that many instructors do not teach their courses in ways best
calculated to achieve the ends that faculties themselves consider important. For example, one
investigator studied samples of the examinations given at elite liberal arts colleges and research
universities. Although 99 percent of professors consider critical thinking an “essential” or “very
important” goal of a college education, fewer than 20 percent of the exam questions actually
tested for this skill.
Now that most faculties have defined the learning objectives of their college and its various
departments and programs, it should be possible to review recent examinations to determine
whether individual professors, programs and departments are actually designing their courses to
achieve those goals. College administrators could also modify their student evaluation forms to
ask students whether they believe the stated goals were emphasized in the courses they took.
In addition, the average time students devote to studying varies widely among different
colleges, and many campuses could require more of their students. Those lacking evidence about
the study habits of their undergraduates could inform themselves through confidential surveys
that faculties could review and consider steps to encourage greater student effort and improve
The vast difference between how well seniors think they can perform and
their actual proficiencies (according to tests of basic skills and employer evaluations) suggests
that many colleges are failing to give students an adequate account of their progress. Grade
inflation may also contribute to excessive confidence, suggesting a need to work to restore
appropriate standards, although that alone is unlikely to solve the problem. Better feedback on
student papers and exams will be even more important in order to give undergraduates a more
accurate sense of how much progress they’ve made and what more they need to accomplish
before they graduate.
More Substantial Reforms
More fundamental changes will take longer to achieve but could eventually yield even
greater gains in the quality of undergraduate education. They include:
Improving graduate education. Colleges and universities need to reconfigure graduate
programs to better prepare aspiring professors for teaching. As late as two or three generations
ago, majorities of new Ph.D.s, at least in the better graduate programs, found positions where
research was primary, either in major universities, industry or government. Today, however,
many Ph.D.s find employment in colleges that are chiefly devoted to teaching or work as adjunct
instructors and are not expected to do research.
Aspiring college instructors also need to know much more now in order to teach
effectively. A large and increasing body of useful knowledge has accumulated about learning
and pedagogy, as well as the design and effectiveness of alternative methods of instruction.
Meanwhile, the advent of new technologies has given rise to methods of teaching that require
special training. As evidence accumulates about promising ways of engaging students actively,
identifying difficulties they are having in learning the material and adjusting teaching methods
accordingly, the current gaps in the preparation most graduate students receive become more and
more of a handicap.
Universities have already begun to prepare graduate students to teach by giving them
opportunities to assist professors in large lecture courses and by creating centers where they can
get help to become better instructors. More departments are starting to provide or even require a
limited amount of instruction in how to teach. Nevertheless, simply allowing grad students to
serve as largely unsupervised teaching assistants, or creating centers where they can receive a
brief orientation or a few voluntary sessions on teaching, will not adequately equip them for a
career in the classroom.
A more substantial preparation is required and will become ever more necessary as the
body of relevant knowledge continues to grow. With all the talk in graduate school circles about
preparing doctoral students for jobs outside academe, one has to wonder why departments spend
time readying Ph.D. candidates for entirely different careers before they have developed
adequate programs for the academic posts that graduate schools are supposed to serve, and that
most of their students continue to occupy.
Many departments may fail to provide such instruction because they lack faculty with
necessary knowledge, but provosts and deans could enlist competent teachers for such
instruction from elsewhere in the university, although they may hesitate to do so, given than
graduate education has always been the exclusive domain of the departments. Enterprising
donors might consider giving grants to graduate schools or departments willing to make the
necessary reforms. If even a few leading universities responded to such an invitation, others
would probably follow suit.
Creating a teaching faculty. The seeds of such a change already exist through the
proliferation of instructors who are not on the tenure track but are hired on a year-to- year basis
or a somewhat longer term to teach basic undergraduate courses. Those adjunct instructors now
constitute as much as 70 percent of all college instructors.
The multiplication of such instructors has largely been an ad hoc response to the need to
cut costs in order to cope with severe financial pressures resulting from reductions in state
support and larger student enrollments. But researchers are discovering that relying on casually
hired, part-time teachers can have adverse effects on graduation rates and the quality of
instruction. Sooner or later, the present practices seem bound to give way to more satisfactory
One plausible outcome would be to create a carefully selected, full-time teaching faculty,
the members of which would lack tenure but receive appointments for a significant term of years
with enforceable guarantees of academic freedom and adequate notice if their contracts are not
renewed. Such instructors would receive opportunities for professional development to become
more knowledgeable and proficient as teachers, and they would teach more hours per week than
the tenured faculty. In return, they would receive adequate salaries, benefits and facilities and
would share in deliberations over educational policy, though not in matters involving research
and the appointment and promotion of tenure-track professors.
These faculty members would be better trained in teaching and learning than the current
research-oriented faculty, although tenured professors who wish to teach introductory or general
education courses would, of course, be welcome to do so. Being chiefly engaged in teaching,
they might also be more inclined to experiment with new and better methods of instruction if
they were encouraged to do so.
A reform of this sort would undoubtedly cost more than most universities currently pay
their non-tenure-track instructors (though less than having tenured faculty teach the lower-level
courses). Even so, the shabby treatment of many part-time instructors is hard to justify, and
higher costs seem inevitable once adjunct faculties become more organized and use their
collective strength to bargain for better terms.
Progress may have to come gradually as finances permit. But instead of today’s legions of
casually hired, underpaid and insecure adjunct instructors, a substantial segment of the college
aiou solved assignments code 837
faculty would possess the time, training and job security to participate in a continuing effort to
develop more effective methods of instruction to engage their students and help them derive
more lasting value from their classes.
Rethinking the undergraduate curriculum. The familiar division into fields of
concentration, electives and general education leaves too little room for students to pursue all of
the objectives that professors themselves deem important for a well-rounded college education.
This tripartite structure, with its emphasis on the major and its embrace of distribution
requirements and extensive electives, was introduced by research universities and designed more
to satisfy the interests of a tenured, research-oriented faculty than to achieve the various aims of
a good undergraduate education. The existing structure is unlikely to change so long as decisions
about the curriculum remain under the exclusive control of the tenure-track professors who
benefit from the status quo.
By now, the standard curriculum has become so firmly rooted that during the periodic
reviews conducted in most universities, the faculty rarely pause to examine the tripartite division
and its effect upon the established goals of undergraduate education. Instead, the practice of
reserving up to half of the required number of credits for the major is simply taken for granted
along with maintaining a distribution requirement and preserving an ample segment of the
curriculum for electives.
The obvious remedy is to include the non-tenure-track instructors who currently make up a
majority of the teaching faculty in curricular reviews so that all those who play a substantial part
in trying to achieve the goals of undergraduate education can participate in the process. It is
anomalous to allow the tenure-track faculty to enjoy exclusive power over the curriculum when
they provide such a limited share of the teaching. Such a reform might be difficult under current
conditions in many colleges where most undergraduate instructors serve part-time, are often
chosen haphazardly and frequently lack either the time or the interest to participate fully in a
review of its undergraduate program. If adjunct instructors achieve the status previously
described, however, their prominent role in teaching undergraduates should entitle them to a seat
at the table to discuss the educational program, including its current structure. Such a move could
at least increase the likelihood of a serious discussion of the existing curricular structure to
determine whether it truly serves the multiple aims of undergraduate education.
Colleges should also consider allowing some meaningful participation by members of the
administrative staff who are prominently involved in college life, such as deans of student affairs
and directors of admission. The current division between formal instruction and the
extracurriculum is arbitrary, since many goals of undergraduate education, such as moral
development and preparation for citizenship, are influenced significantly by the policies for
admitting students, the administration of rules for student behavior, the advising of
undergraduates, the nature of residential life and the extracurricular activities in which many
students participate. Representatives from all groups responsible for the policies and practices
that affect these goals should have something to contribute to reviews of undergraduate
The Need for Research
Finally, there is an urgent need for more and better research both to improve the quality of
undergraduate education and to increase the number of students who complete their studies.
Among the many questions deserving further exploration, four lines of inquiry seem especially
How can remedial education be improved? At present, low rates of completion in remedial
courses are a major impediment to raising levels of educational attainment. The use of computer-
aided instruction in remedial math provides one promising example of the type of improvement
that could yield substantial benefits, and there are doubtless other possibilities.
Far too little is known about the kinds of courses or other undergraduate experiences that
contribute to such noneconomic benefits in later life as better health, greater civic participation
and lower incidence of substance abuse and other forms of self-destructive behavior. Better
understanding of those connections could help educators increase the lasting value of a college
education while providing a stronger empirical basis for the sweeping claims frequently made
about the lifelong benefits of a liberal education. Such understanding would also reduce the risk
of inadvertently eliminating valuable aspects of a college education in the rush to find quicker,
cheaper ways of preparing students to obtain good jobs of immediate value to economic growth.
Existing research suggests that better advising and other forms of student support may
substantially enhance the effect of increased financial aid in boosting the numbers of students
who complete their studies. With billions of dollars already being spent on student grants and
loans, it would clearly be helpful to know more about how to maximize the effects of such
subsidies on graduation rates.
More work is needed to develop better ways for colleges to measure student learning, not
only for critical thinking and writing but also for other purposes of undergraduate education.
The importance of this last point can scarcely be overestimated. Without reliable measures
of learning, competition for students can do little to improve the quality of instruction, since
applicants have no way of knowing which college offers them the best teaching. Provosts, deans
and departments will have difficulty identifying weaknesses in their academic programs in need
of corrective action. Academic leaders will be handicapped in trying to persuade their professors
to change the way they teach if they cannot offer convincing evidence that alternative methods
will bring improved results. Faculty members will do less to improve their teaching if they
continue to lack adequate ways to discover how much their students are learning.
All these reforms could do a lot to improve the quality of undergraduate education — as
well as increase levels of attainment. With more research and experimentation, other useful ideas
will doubtless continue to appear.

Question 3: Discuss each type of research by purpose.
Types of research methods can be broadly divided into two quantitative and qualitative
Quantitative research “describes, infers, and resolves problems using numbers. Emphasis is
placed on the collection of numerical data, the summary of those data and the drawing of
inferences from the data”.
Qualitative research, on the other hand, is based on words, feelings, emotions, sounds and
other non-numerical and unquantifiable elements. It has been noted that “information is
considered qualitative in nature if it cannot be analysed by means of mathematical techniques.
This characteristic may also mean that an incident does not take place often enough to allow
reliable data to be collected”
According to the purpose of the study, types of research methods can be divided into two
categories: applied research and fundamental research. Applied research is also referred to as an
action research, and the fundamental research is sometimes called basic or pure research. The
table below summarizes the main differences between applied research and fundamental
research. Similarities between applied and fundamental (basic) research relate to the adoption
of a systematic and scientific procedure to conduct the study.
Pure research is theoretical type not a practical one. Pure research is the knowledge of facts
and theories to give us satisfaction of knowledge and understanding. It discovers general
principles for a problem solution. Following are some of the features.
1.It keeps the foundation of initial study.
2.It discovers new facts.
3.It gives theoretical reports for solution.
Applied research is the implementation of theoretical study upon a problematic situation. It
applied its theories and facts to know about the nature of the problem and give a concrete shape
for the solution. This is practical work in the field. Following are the features of such type of
1.It tests and verifies theories
2.It discovers new facts
3.It gives immediate answer to a question
Action research is based on the taking of immediate action on a happening, event or
situation. The researcher is actively involved in the solution of the problems. Second World War
created many types of problems for which action research was necessary. These problems
including (flood, epidemic, earthquake, fire) etc. features are as under.
1.It is quick service oriented
2.It is taking immediate action
3.It is sensitive to time and place
This type of research is an evaluation of some programs working for the construction of
problematic areas. It is the dankness of implemented programmes about their effects and positive
aiou solved assignments code 837
solution. There are three main types of evaluation.
1.Concurrent evaluation-means continuous process
2.Phase or periodic evaluation-stage wise.
3.Terminal evaluation-Evaluation after the completion of the programme.
Inter Disciplinary Research
It is the study of structure or functions of a particular discipline or comparison of one
discipline with another. In other words it is the comparison of a developmental stage. It is also
called co-ordinate research. Features are the following.
1.It is a cooperative research
2.It helps in study the whole phenomena
It brings comparison in different disciplines

Question 4: Differentiate between descriptive and experimental research. Which one
is most suitable in distance and non-formal education and why?
The main difference between descriptive and experimental research is that the descriptive
research describes the characteristics of the study group or a certain occurrence while the
experimental research manipulates the variables to arrive at conclusions.
Descriptive research and experimental research are two types of research people use when
doing varied research studies. Both these research types have their own methods that facilitate
the researcher to gain maximum outcomes.
Descriptive research is a type of research that studies the participants that take part in the
research or a certain situation. Descriptive research does not limit to either of quantitative or
qualitative research methodologies, but instead, it uses elements of both, often within the same
study. Therefore, a descriptive researcher often uses three major ways to collect and analyse the
data. They are observations, case studies and surveys.
Descriptive studies are aimed at finding out “what is,” therefore, observational and survey
methods are frequently used to collect descriptive data (Borg & Gall, 1989). Thus, the main
focus of descriptive research is to answer the question ‘what’ with concern to the study group.
Moreover, descriptive research, primarily concerned with finding out “what is,” that might be
applied to investigate the particular study group or the situation. Therefore, descriptive research
does not give answers to the cause and effect of the particular occurrence that is studied.
Therefore, descriptive research assists to make specific conclusions regarding situations
such as marketing products according to the needs of the customers, to estimate the percentages
of units in a specified population according to a certain behaviour, etc. Some examples of
descriptive researches include population census and product marketing surveys.
Experimental research is the research study where the scientist actively influences
aiou solved assignments code 837
something to observe the consequences. Experimental research uses manipulation and controlled
testing to understand causal processes. Therefore, in this type of research, the researcher
manipulates one given variable and controls the others to come to a conclusion.
This type of research typically includes a hypothesis, a variable that can be manipulated,
measured, calculated and compared. Eventually, the collected data and results will either support
or reject the hypothesis of the researcher. Therefore, one could call this research type as a true
In this research type, the researcher manipulates the independent variables such as
treatment method and teaching methodology, and measures the impact it has on the dependent
variables such as cure and student comprehension in order to establish a cause-effect relationship
between these two variables. Therefore, this research type can answer the questions of cause,
effect and results, thus, making it possible to make hypothetical assumptions based on the
gathered data. Therefore, unlike descriptive research which answers’ what is’, experimental
research answers the question ‘what if’. Therefore, usually, this type of research uses quantitative
data collection methodology.
Evidently, this type of research is mostly conducted in a controlled environment, usually a
laboratory. Experimental research is mostly used in sciences such as sociology and psychology,
physics, chemistry, biology, medicine, etc.
Difference Between Descriptive and Experimental Research
Descriptive research is the type of research where characteristics of the study group or a
certain occurrence are described while experimental research is the research type that
manipulates variables to come to a conclusion. This is the main difference between descriptive
and experimental research.
Descriptive research is useful in gathering data on a certain population or a specific
occurrence while experimental research is useful in finding out the cause-effect of a causal
relationship, correlation etc
The aim of the descriptive research is to describe the characteristics of the study group,
thus answering the question ‘what is’ while the aim of the experimental research is to manipulate
the given variables so as to support or reject the assumed hypothesis. Hence it answers the
question ‘what if’.
Type of Studies
Descriptive research typically includes sociological and psychological studies while
experimental research typically includes forensic studies, biological and other laboratory studies,
Descriptive research uses both qualitative and quantitative methodologies while
experimental research primarily uses quantitative methodology.
Descriptive and experimental research are two significant types of research. Both these
research types are helpful in analysing certain occurrences and study groups. The main
difference between descriptive and experimental research is that descriptive research describes
the characteristics of the research subject while the experimental research manipulates the
research subject or the variables to come to a conclusion. Similarly, descriptive research answers
the question ‘what is’ while experimental research answers the question ‘what if’.

Question 5: Write a detailed note on historical research.
Historical research or historiography, “attempts to systematically recapture the complex
nuances, the people,meanings,events,and even ideas of the past that have influenced and shaped
the present”. (Berg & Lure, 2012, p. 305 )
Historical research relies on a wide variety of sources, both primary & secondary including
Historical research involves studying, understanding and interpreting past events. The
purpose of historical research is to reach insights or conclusions about past persons or
occurrences. Historical research entails more than simply compiling and presenting factual
information; it also requires interpretation of the information.
Typically, histories focuses on particular individuals, social issues and links between the
old and the new. Some historical research is aimed at reinterpreting prior historical works by
revising existing understandings and replacing them with new, often politically charged ones.
The main emphasis in historical research is on interpretation of documents, diaries and the
like. Historical data are categorized into primary or secondary sources. Primary
sources include first hand information, such as eyewitness reposts and original
documents. Secondary sources include secondhand information, such as a description of an
event by someone other than an eyewitness, or a textbook author’s explanation of an event or
theory. Primary sources may be harder to find but are generally more accurate and preferred by
historical researchers. A major problem with much historical research is excessive reliance on

Researches cannot accept historical data at face value, since many diaries memoirs, reposts
and testimonies are written to enhance the writer’s position, stature, or importance. Because of
this possibility, historical data has to be examined for its authenticity and truthfulness. Such
examination is done through criticism; by asking and researching to help determine truthfulness,
bias, omissions and consistency in data.
Historical research can be defined as the process of investigating past events systematically
to provide an account of happenings in the past (Historical Research, n.d.). It is not simply the
accumulation of dates and facts or even just a description of past happenings but is a flowing and
aiou solved assignments code 837
dynamic explanation or description of past events which include an interpretation of these events
in an effort to recapture implications, personalities and ideas that have influenced these events
(ibid). Berg (2000) stressed that it is crucial to distinguish nostalgia from historical research
since the former is the retelling of comfortable past pleasantries, events or situations that lacks
research vigour while the later attemp ~ 1 ~ Hartman, 2000).
In addition, it also encourages interdisciplinary inquiry and understanding (ibid). On top of
that, it is intellectually enriching and challenging as historical research often ask the thought-
provoking question of ‘why’ (ibid). And finally, historical research is fun because there are no
other disciplines that allow one to poke their noses into the concerns of others and then label it as
serious academic work (ibid). According to Lundi (2008), there are five stages to undertake in
historical researches, namely (i) the identification of a researchable phenomenon that involves
reading relevant literature, listening to current views about the phenomenon and reflecting on the
researcher’s interest before choosing a specific time period, person, phenomena or era related to
the focus of the study; (ii) the development of hypotheses or research questions and the
identification of a theoretical perspective that will guide the process of data collection and results
interpretation besides helping researcher focus and interpret historical occurrences as recorded;
(iii) the data exploration and collection stage where it can be the most time-consuming and
labour-intensive part as the research process is dependent on the subject of study and the
accessibility of data sources; (iv) the checking of facts, evaluation of the validity and reliability
of data, and the analysis of evidence gathered from each source where the researcher evaluate the
data and forms generalizations to accepts or rejects hypotheses or to answer research questions
and forms conclusions; and (v) the writing of the report in which findings are described along
aiou solved assignments code 837
with interpretations and provides detailed supportive evidence in defence of the conclusions
made. Data sources for historical research can be taken from either primary sources or secondary
sources (Berg, 2001; Lundy, 2008; Moore, Monaghan & Hartman, 1997).
Primary sources are first-person accounts that involve the oral or written testimony of
eyewitnesses and these may include documents, letter, observational notes, photographs,
recordings, diaries, journals, life histories, drawings, mementos and other relics (Berg, 2001;
Lundy; 2008). Salkind (1996 as cited in Berg 2001) stated that primary sources are usually
original artefacts, documents and items related to the direct outcomes of an event or an
experience. In general, primary sources are created at or very near the time of the historical event
that is being described (Lundy, 2008). In contrast, secondary sources are account descriptions of
persons who are not eyewitnesses of the event or who did not personally know the person being
studied (ibid). They are from people who are not immediately present at the time of the event and
these are referred to as second-hand or hearsay accounts of someone, some happenings or some
development (Berg, 2001). Secondary sources can be in form of biographies, scholarly articles,
popular books, reference books, textbooks, court records, lab information, encyclopaedias,
newspaper articles and even obituary notices (Berg, 2001; Lundy; 2008). ~ 2 ~ There are
generally four approaches to historical research and these all utilise primary sources as their chief
database (Monaghan & Hartman, 2000). However, Monaghan and Hartman (2000) noted that
these four approached are not exclusive as researchers use as many of the approaches as their
question, topic and time would allow. This integration is made possible due to the nature of
historical research that cuts across genres of approaches as can be seen in Barry’s (1992) and
Spiker’s (1997) dissertations when they employ all four approaches (ibid). The four approaches
proposed by Monaghan and Hartman (2000) are (i) qualitative approach (also known as history
by quotation) where the search for a story construed from a range of printed or written evidence
and the resultant history is arranged chronologically and presented as a factual tale and the
sources range from manuscripts (such as account books, school records, marginalia, letters,
diaries and memoirs) to imprints (such as textbooks, journals, children’s books and other books
of the period under consideration); (ii) quantitative approach where researchers intentionally
look for evidence that lends itself to be quantifiable and is thus presumed to have superior
validity and generalizability with the assumption that broader questions can then be addressed
more authoritatively; (iii) content analysis where the text itself is the object of scrutiny that uses
published works as its data and subjects them to careful analyses that ordinarily include both the
qualitative and quantitative aspects; and (iv) oral history which focuses on living memory where
researchers gather personal recollections of events from living individuals via audio and video
recording that gives respondents a natural and effective environment to provide a reciprocal
interchange between them and the researchers. The validity of historical research can be
established through external criticism while its reliability is determined via internal criticism
(Lundy, 2008; Berg, 2001).
External and internal criticisms are essential to ascertain the quality of the data that will
in turn affect the quality of the depth of interpretations and analyses since the rigorous
examinations of the internal and external value of the data will ensure valid and reliable
information as well as viable historical analyses (Berg, 2001). The primary concern of external
criticism is the genuineness of resource materials (ibid). It is extremely crucial for researchers to
evaluate their sources with great care, or even get verification from experts, to ensure that
sources are authentic to avoid frauds, hoaxes and forgeries as these are not uncommon and can
prove to be problematic (Lundy, 2008; Berg, 2001). On the other hand, for researchers to
determine the reliability of a source using internal criticism, the trustworthiness of the source is
questioned, such as the author’s perceptions and biases of the phenomena, and whether the
author is reporting from intimate knowledge or from other’s description of the event (Lundy,
2008). Lundy (2008) cautioned researchers to be vigilant in including both positive and negative
criticism of all data sources which includes missing accounts, lack of relevant viewpoints and the
persons involved in the event.
