Q.1. State different methods to enhance the reliability of the measurement tool also

explain each type by providing examples.

Answer:

Reliability

What does the term reliability mean? Reliability means Trustworthy. A test score is

called reliable when we have reasons for believing the test score to be stable and objective.

For example if the same test is given to two classes and is marked by different teachers

even then it produced the similar results, it may be considered as reliable. Stability and

trustworthiness depends upon the degree to which score is free of chance error. We must

first build a conceptual bridge between the question asked by the individual (i.e. are my

scores reliable?) and how reliability is measured scientifically. This bridge is not as simple

as it may first appear. When a person thinks of reliability, many things may come into his

mind – my friend is very reliable, my car is very reliable, my internet bill-paying process is

very reliable, my client’s performance is very reliable, and so on. The characteristics being

addressed are the concepts such as consistency, dependability, predictability, variability

etc. Note that implicit, reliability statements, is the behaviour, machine performance, data

processes, and work performance may sometimes not reliable. The question is “how much

the scores of tests vary over different observations?”

Some Definitions of Reliability: According to Merriam

Webster Dictionary:

“Reliability is the extent to which an experiment, test, or measuring procedure yields the

same results on repeated trials.”

According to Hopkins & Antes (2000):

“Reliability is the consistency of observations yielded over repeated recordings either for

one subject or a set of subjects.”

Joppe (2000) defines reliability as:

“…The extent to which results are consistent over time and an accurate representation of

the total population under study is referred to as reliability and if the results of a study can

be reproduced under a similar methodology, then the research instrument is considered to

be reliable.” (p. 1)

The more general definition of the reliability is: The degree to which a score is stable and

consistent when measured at different times (test-retest reliability), in different ways

(parallel-forms and alternate-forms), or with different items within the same scale (internal

consistency).

Types of Reliability

Reliability is one of the most important elements of test quality. It has to do with the

consistency, or reproducibility, of an examinee’s performance in the test. It’s not possible

to calculate reliability exactly. Instead, we have to estimate reliability, and this is always

an imperfect attempt. Here, we introduce the major reliability estimators and talk about

their strengths and weaknesses.

There are six general classes of reliability estimates, each of which estimates reliability in a

different way. They are:

i. Inter-Rater or Inter-Observer Reliability

To assess the degree to which different raters/observers give consistent estimates of the

same phenomenon. That is if two teachers mark same test and the results are similar, so it

indicates the inter-rater or inter-observer reliability.

ii. Test-Retest Reliability:

To assess the consistency of a measure from one time to another, when a same test is

administered twice and the results of both administrations are similar, this constitutes the

test-retest reliability. Students may remember and may be mature after the first

administration creates a problem for test-retest reliability.

iii. Parallel-Form Reliability:

To assess the consistency of the results of two tests constructed in the same way from the

same content domain. Here the test designer tries to develop two tests of the similar kinds

and after administration the results are similar then it will indicate the parallel form

reliability.

i. Internal Consistency Reliability:

To assess the consistency of results across items within a test, it is correlation of the individual items score with the entire test.

ii. Split half Reliability:

To assess the consistency of results comparing two halves of single test, these halves may be

even odd items on the single test.

iii. Kuder-Richardson Reliability:

To assess the consistency of the results using all the possible split halves of a test. Let’s

discuss each of these in turn.

Q.2. Explain the effects of curricular validity on performance of the examines. How can

you measure the curricular validity of tests Elaborate in detail.

Answer:

Curricular Validity

The extent to which the content of the test matches the objectives of a specific curriculum as it is

formally described. Curricular validity takes on particular importance in situations where tests are

used for high-stakes decisions, such as Punjab Examination Commission exams for fifth and

eight grade students and Boards of Intermediate and Secondary Education Examinations. In

these situations, curricular validity means that the content of a test that is used to make a

decision about whether a student should be promoted to the next levels should measure the

curriculum that the student is taught in schools.

Curricular validity is evaluated by groups of curriculum/content experts. The experts are

asked to judge whether the content of the test is parallel to the curriculum objectives and

whether the test and curricular emphases are in proper balance. Table of specification

may help to improve the validity of the test.

Functions of Test Scores and Progress Reports

The task of grading and reporting students’ progress cannot be separated from the procedures

adopted in assessing students’ learning. If instructional objectives are well defined in terms of

behavioural or performance terms and relevant tests and other assessment procedures are

properly used, grading and reporting become a matter of summarizing the results and presenting

them in understandable form. Reporting students’ progress is difficult especially when data is

represented in single letter-grade system or numerical value (Linn & Gronlund, 2000).

Assigning grades and making referrals are decisions that require information about individual

students. In contrast, curricular and instructional decisions require information about groups of

students, quite often about entire classrooms or schools (Linn & Gronlund, 2000).

There are three primary purposes of grading students. First, grades are the primary currency for

exchange of many of the opportunities and rewards our society has to offer. Grades can be

exchanged for such diverse entities as adult approval, public recognition, college and university

admission etc. To deprive students of grades means to deprive them of rewards and

opportunities. Second, teachers become habitual of assessing their students’ learning in grades,

and if teachers don’t award grades, the students might not well know about their learning

progress. Third, grading students motivate them. Grades can serve as incentives, and for many

students incentives serve a motivating function.

The different functions of grading and reporting systems are given as under:

1. Instructional uses

The focus of grading and reporting should be the student improvement in learning. This is most

likely occur when the report: a) clarifies the instructional objectives; b) indicates the student’s

strengths and weaknesses in learning; c) provides information concerning the student’s personal

and social development; and d) contributes to student’s motivation.

The improvement of student learning is probably best achieved by the day-to-day assessments

of learning and the feedback from tests and other assessment procedures. A portfolio of work

developed during the academic year can be displayed to indicate student’s strengths and

weaknesses periodically.

Periodic progress reports can contribute to student motivation by providing short-term

goals and knowledge of results. Both are essential features of essential learning. Well-

designed progress reports can also help in evaluating instructional procedures by

identifying areas need revision. When the reports of majority of students indicate poor

progress, it may infer that there is a need to modify the instructional objectives

2. Feedback to students

Grading and reporting test results to the students have been an on-going practice in all the

educational institutions of the world. The mechanism or strategy may differ from country to

country or institution to institution but each institution observes this practice in any way. Reporting

test scores to students has a number of advantages for them. As the students move up through

the grades, the usefulness of the test scores for personal academic planning and self-

assessment increases. For most students, the scores provide feedback about how much they

know and how effective their efforts to learn have been. They can know their strengths and areas

need for special attention. Such feedback is essential if students are expected to be partners in

managing their own instructional time and effort. These results help them to make good decisions

for their future professional development.

Teachers use a variety of strategies to help students become independent learners who are able

to take an increasing responsibility for their own school progress. Self-assessment is a significant

aspect of self-guided learning, and the reporting of test results can be an integral part of the

procedures teachers use to promote self-assessment. Test results help students to identify areas

need for improvement, areas in which progress has been strong, and areas in which continued

strong effort will help maintain high levels of achievement. Test results can be used with

information from teacher’s assessments to help students set their own instructional goals, decide

how they will allocate their time, and determine priorities for improving skills such as reading,

writing, speaking, and problem solving. When students are given their own test results, they can

learn about self-assessment while doing actual self-assessment. (Iowa Testing Programs, 2011).

Grading and reporting results also provide students an opportunity for developing an awareness

of how they are growing in various skill areas. Self-assessment begins with self-monitoring, a skill

most children have begun developing well before coming to kindergarten.

3. Administrative and guidance uses

Grades and progress reports serve a number of administrative functions. For example, they are

used for determining promotion and graduation, awarding honours, determining sports eligibility

of students, and reporting to other institutions and employers. For most administrative purposes,

a single letter-grade is typically required, but of course, technically single letter-grade does not

truly interpret student’s assessment.

Guidance and Counseling officers use grades and reports on student’s achievement,

along with other information, to help students make realistic educational and vocational

plans. Reports that include ratings on personal and social characteristics are also useful

in helping students with adjustment problems.

Without any doubt, it is more effective to talk parents to face about their children’s scores than to

send a score report home for them to interpret on their own. For a variety of reasons, a parent-

teacher or parent-student-teacher conference offers an excellent occasion for teachers to provide

and interpret those results to the parents.

1. Teachers tend to be more knowledgeable than parents about tests and the types of scores

being interpreted.

2. Teachers can make numerous observations of their student’s work and consequently

substantiate the results. In-consistencies between test scores and classroom performance can

be noted and discussed.

3. Teachers possess work samples that can be used to illustrate the type of classroom work the

student has done. Portfolios can be used to illustrate strengths and to explain where improvements are needed.

4. Teachers may be aware of special circumstances that may have influenced the scores, either

positively or negatively, to misrepresent the students’ achievement level.

Reliability is a measure of the consistency of a metric or a method. Every metric or method we

use,

including things like methods for uncovering usability problems in an interface and expert

judgment, must

be assessed for reliability. In fact, before you can establish validity, you need to establish

reliability. Here

are the four most common ways of measuring reliability for any empirical method or metric:

• inter-rater reliability

• test-retest reliability

• parallel forms reliability

• internal consistency reliability

 Q.3. Write down learning outcomes for any unit of Social Studies for 8th grade and develop

an essay type test item with rubric,5 multiple choice questions and 5 short question for

the written learning outcomes.

Answer

Achievement Tests

Achievement tests are widely used throughout education as a method of assessing and

comparing student performance. Achievement tests may assess any or all of reading, math, and

written language as well as subject areas such as science and social studies. These tests are

available to assess all grade levels and through adulthood. The test procedures are highly

structured so that the testing process is the same for all students who take them.

It is developed to measure skills and knowledge learned in a given grade level, usually through

planned instruction, such as training or classroom instruction. Achievement tests are often

contrasted with tests that measure aptitude, a more general and stable cognitive trait.

Achievement test scores are often used in an educational system to determine what level of

instruction for which a student is prepared. High achievement scores usually indicate a mastery

of grade-level material, and the readiness for advanced instruction. Low achievement scores can

indicate the need for remediation or repeating a course grade.

Teachers evaluate students by: observing them in the classroom, evaluating their day-to-day

class work, grading their homework assignments, and administrating unit tests. These classroom

assessments show the teacher how well a student is mastering grade level learning goals and

provide information to the teacher that can be used to improve instruction. Overall achievement

testing serves following purposes:

· Assess level of competence

· Diagnose strength and weaknesses

· Assign Grades

· Achieve Certification or Promotion

· Advanced Placement/College Credit Exams

· Curriculum Evaluation

· Accountability

· Informational Purposes

(i) Types of Achievement Tests

(a) Summative Evaluation:

Testing is done at the end of the instructional unit. The test score is seen as the summation of all

knowledge learned during a particular subject unit.

(a) Formative Evaluation:

Testing occurs constantly with learning so that teachers can evaluate the effectiveness of

teaching methods along with the assessment of students’ abilities.

(ii) Advantages of Achievement Test:

· One of the main advantages of testing is that it is able to provide assessments that are

psychometrically valid and reliable, as well as results which are generalized and replicable.

· Another advantage is aggregation. A well designed test provides an assessment of an

individual’s mastery of a domain of knowledge or skill which at some level of aggregation will

provide useful information. That is, while individual assessments may not be accurate enough for

practical purposes, the mean scores of classes, schools, branches of a company, or other groups

may well provide useful information because of the reduction of error accomplished by increasing

the sample size.

(iii) Designing the Test

Step 1: The first step in constructing an effective achievement test is to identify what you want

students to learn from a unit of instruction. Consider the relative importance of the objectives and

include more questions about the most important learning objectives.

Writing the questions:

Step2: Once you have defined the important learning objectives and have, in the light of these

objectives, determined which types of questions and what form of test to use, you are ready to

begin the second step in constructing an effective achievement test. This step is writing the

questions.

Step3: Finally, review the test. Are the instructions straightforward? Are the selected learning

objectives represented in appropriate proportions? Are the questions carefully and clearly

worded? Special care must be taken not to provide clues to the test-wise student. Poorly

constructed questions may actually measure not knowledge, but test-taking ability.

(iv) General Principles:

While the different types of questions–multiple choice, fill-in-the-blank or short answer, true-false,

matching, and essay–are constructed differently, the following principles apply to construct

questions and tests in general.

· Make the instructions for each type of question simple and brief.

· Use simple and clear language in the questions. If the language is difficult, students who

understand the material but who do not have strong language skills may find it difficult to

demonstrate their knowledge. If the language is ambiguous, even a student with strong language

skills may answer incorrectly if his or her interpretation of the question differs from the instructor’s

intended meaning.

· Write items that require specific understanding or ability developed in that course, not just

general intelligence or test-wiseness.

Q.3.Describe the measurement of central tendency. Also elaborate how these measures

can be utilize in the interpretation of the test results? Provide examples where necessary .

Answer

Measures of Central Tendency

Suppose that a teacher gave the same test to two different classes and following results are

obtained:

Class 1: 80%, 80%, 80%, 80%, 80%

Class 2: 60%, 70%, 80%, 90%, 100%

If you calculate the mean for both sets of scores, you get the same answer: 80%. But the data of

two classes from which this mean was obtained was very different in the two cases. It is also

possible that two different data sets may have same mean, median, and mode. For example:

Class A: 72 73 76 76 78

Class B: 67 76 76 78 80

Therefore class A and class B has same mean, mode, and median.

The way that statisticians distinguish such cases as this is known as measuring the variability of

the sample. As with measures of central tendency, there are a number of ways of measuring the

variability of a sample.

Probably the simplest method is to find the range of the sample, that is, the difference between

the largest and smallest observation. The range of measurements in Class 1 is 0, and the range

in class 2 is 40%. Simply knowing that fact gives a much better understanding of the data

obtained from the two classes. In class 1, the mean was 80%, and the range was 0, but in class

2, the mean was 80%, and the range was 40%.

Statisticians use summary measures to describe patterns of data. Measures of central

tendency refer to the summary measures used to describe the most “typical” value in a set of

values.

Here, we are interested in the typical, most representative score. There are three most common

measures of central tendency are mean, mode, and median. A teacher should be familiar with

these common measures of central tendencies.

Mean

The mean is simply the arithmetic average. It is sum of the scores divided by the number of

scores. it is computed by adding all of the scores and dividing by the number of scores. When

statisticians talk about the mean of a population, they use the Greek letter μ to refer to the mean

score. When they talk about the mean of a sample, statisticians use the symbol to refer to the mean score.

It is symbolized as: = X N X ·

(read as “X-Bar”) when computed on a sample Computation – Example: find the mean of 2,3,5,

and 10.

X =N

··X

= 4 Example 1

The marks of seven students in a mathematics test with a maximum possible m are

given below:

15 13 18 16 14 17 12

Find the mean of this set of data values.

Solution: 2 ·3·5·10=420= 5

Since means are typically reported with one more digit of accuracy that is present in the data, I

reported the mean as 5.0 rather than just 5.

So, the mean mark is 15.

Symbolically, we can set out the solution as follows:

So, the mean mark is 15.

When working with grouped frequency distributions, we can use an approximation:

Where Mdpt. is midpoint of the group

For example:

Interval Midpoint f Mid*f

95-99 97 1 97

90-94 92 3 276

85-89 87 5 435

80-84 82 6 492

75-79 77 4 308

70-74 72 3 216

65-69 67 1 67

60-64 62 2 124

f=25=N Mid*f=2015

Q.5.Briefly describe the present trends and class room techniques use by teachers for the

formative assessment of the students learning. Also enlist the components of a good

progress report.

Answer

According to Carole Tomlinson “Assessment is today’s means of modifying tomorrow’s

instruction.” It is an integral part of teaching learning process. It is widely accepted that

effectiveness of teaching learning process is directly influenced by assessment. Hamidi (2010)

developed a framework to answer the Why; What, How and When to assess. This is helpful in

understanding the true nature of this concept.

Why to Assess: Teachers have clear goals for instruction and they assess to ensure that these

goals have been or are being met. If objectives are the destination, instruction is the path to it

then assessment is a tool to keep the efforts on track and to ensure that the path is right. After

the completion of journey assessment is the indication that destination is ahead.

a) Assessment for Learning (Formative Assessment)

Assessment for learning is a continuous and an ongoing assessment that allows teachers to

monitor students on a day-to-day basis and modify their teaching based on what the students

need to be successful. This assessment provides students with the timely, specific feedback that

they need to enhance their learning. The essence of formative assessment is that the information

yielded by this type of assessment is used on one hand to make immediate decisions and on the

other hand based upon this information; timely feedback is provided to the students to enable

them to learn better. If the primary purpose of assessment is to support high-quality learning then

formative assessment ought to be understood as the most important assessment practice.

Garrison, & Ehringhaus, (2007) identified some of the instructional strategies that can be used for

formative assessment:

· Observations. Observing students’ behaviour and tasks can help teacher to identify if

students are on task or need clarification. Observations assist teachers in gathering evidence of

student learning to inform instructional planning.

· Questioning strategies. Asking better questions allows an opportunity for deeper thinking and

provides teachers with significant insight into the degree and depth of understanding. Questions

of this nature engage students in classroom dialogue that both uncovers and expands learning.

· Self and peer assessment. When students have been involved in criteria and goal setting,

self-evaluation is a logical step in the learning process. With peer evaluation, students see each

other as resources for understanding and checking for quality work against previously

established criteria.

xix · Student record keeping It also helps the teachers to assess beyond a “grade,” to see where

the learner started and the progress they are making towards the learning goals.

b) Assessment of Learning (Summative Assessment)

Summative assessment or assessment of learning is used to evaluate students’ achievement at

some point in time, generally at the end of a course. The purpose of this assessment is to help

the teacher, students and parents know how well student has completed the learning task. In

other words summative evaluation is used to assign a grade to a student which indicates his/her

level of achievement in the course or program.

Assessment of learning is basically designed to provide useful information about the performance

of the learners rather than providing immediate and direct feedback to teachers and learners,

therefore it usually has little effect on learning. Though high quality summative information can

help and guide the teacher to organize their courses, decide their teaching strategies and on the

basis of information generated by summative assessment educational programs can be modified.

Many experts believe that all forms of assessment have some formative element. The difference

only lies in the nature and the purpose for which assessment is being conducted.

Consortium

c) Assessment as Learning

Assessment as learning means to use assessment to develop and support students’

metacognitive skills. This form of assessment is crucial in helping students become lifelong

learners. As students engage in peer and self-assessment, they learn to make sense of

information, relate it to prior knowledge and use it for new learning. Students develop a

sense of efficacy and critical thinking when they use teacher, peer and self-assessment

feedback to make adjustments, improvements and changes to what they understand.
