EDUCATIONAL ASSESSMENT AND
EVALUATION (8602)
MEASUREMENT, ASSESSMENT AND
EVALUATION
Concept of Measurement Assessment
and Evaluation
• Despite their significant role in education the
terms measurement, assessment, and evaluation
are usually confused with each other.
• Mostly people use these terms interchangeably
and feel it very difficult to explain the differences
among them.
• Each of these terms has a specific meaning
sharply distinguished from the others.
Measurement
• Measurement: In general, the term measurement is used
to determine the attributes or dimensions of object. For
example, we measure an object to know how big, tall or
heavy it is.
• In educational perspective measurement refers to the
process of obtaining a numerical description of a student’s
progress towards a pre-determined goal.
• This process provides the information regarding how much
a student has learnt. Measurement provides quantitative
description of the students’ performance for example
Rafaih solved 23 arithmetic problems out of 40.
• But it does not include the qualitative aspect for example,
Rafaih’s work was neat.
Testing
• A test is an instrument or a systematic
procedure to measure a particular
characteristic. For example, a test of
mathematics will measure the level of the
learners’ knowledge of this particular subject
or field.
• A test is a set of items.
Assessment
• Assessment: Kizlik (2011) defines assessment as a process by which
information is obtained relative to some known objective or goal.
Assessment is a broad term that includes testing.
• For example, a teacher may assess the knowledge of English
language through a test and assesses the language proficiency of
the students through any other instrument for example oral quizor
presentation.
• Based upon this view, we can say that every test is assessment but
every assessment is not the test.
• In short, we can say that assessment entails much more than
testing. It is an ongoing process that includes many formal and
informal activities designed to monitor and improve teachingand
learning.
Evaluation
• Evaluation: Hopkins and Antes (1990) defined evaluation asa
continuous inspection of all available information in order to
form a valid judgment of students’ learning and/or the
effectiveness of education program.
• The central idea in evaluation is "value." When we evaluate a
variable, we are basically judging its worthiness,
appropriateness and goodness. Evaluation is always done
against a standard, objectives or criterion.
• In teaching learning process teachers made students’
evaluations that are usually done in the context of
comparisons between what was intended (learning, progress,
behaviour) .
Assessment for Learning
(Formative Assessment)
• Checks how students are learning
and is there any problem in
learning process. it determines
what to do next.
• Is designed to assist educators
and students in improving
learning?
• Usually focuses on improvement,
compared with the student's own
previous performance
Assessment of Learning
(Summative Assessment)
• Checks what has been learned to
date.
• Is designed to provide information
to those not directly involved in
classroom learning and teaching
(school administration, parents,
school board), in addition to
educators and students?
• Usually compares the student's
learning either with other students'
learning (norm-referenced) or the
standard for a grade level (criterion
referenced)
Test
 A test is a device which is used to measure
behaviour ofa person for a specific purpose.
 Moreover it is an instrument that typically
uses sets of items designed to measure a
domain of learning tasks.
 Tests are systematic method of collecting
information that lead to make inferences
about the characteristics of people or
objects.
 teacher prepares tests while sampling the
items froma
 pool of items in such a way that it represents
thewhole subject matter.
Taxonomy ofEducational
Objectives
 Benjamin Bloom established a
hierarchy of educational objectives for
categorizing level of abstraction of
questions that commonly occur in
educational settings (Bloom, 1965).
The classification is generally
referred to as
Bloom'sTaxonomy.Taxonomy means
'a set of classification principles',
or 'structure'.The followings are six
levels in this taxonomy:
Levels ofDomains
SOLO Taxonomy
 SOLO taxonomy was developed by Biggs and
Collis (1982) Stands for Structure of Observed
Learning Outcomes

Selection Type Items (objective type)
There are four types of test items in selection
category of test which are in common use today.
multiple-choice, matching, true-false, and
completion items.
What is a Multiple Choice
Question (MCQ)?
A multiple-choice question is a type of
questionnaire/survey question that provides respondents
with multiple answer options. Sometimes called objective
response questions, it requires respondents to select only
correct answers from the choice options.
MCQs are mostly used in educational testing, customer
reviews, market research, elections, etc. Although they
take different forms depending on their purpose, they
have the same structure.
Validity Reliability
 Reliability means Trustworthy, Consistency
 A testscoreiscalled reliablewhenwehavereasonsfor
believing thetestscoretobestableand objective.
 According to Merriam WebsterDictionary:
“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.”
 Inter-Rater orInter-ObserverReliability
 Test-RetestReliability
 Parallel-Form Reliability
 Internal ConsistencyReliability
 Split half Reliability
 Kuder-RichardsonReliability
Validity
 The validity of an assessment tool is the degree to which itmeasures
for what it is designed to measure.
 The concept refers to the appropriateness, meaningfulness,and
usefulness of the specific inferences

Relationship between Validity
and Reliability
 Reliability is a necessary requirement for validity
 Establishing good reliability is only the first part of establishing validity
 Reliability is necessary but not sufficient forvalidity.
Planning a Test
The main objective of classroom
assessment is to obtain valid, reliable and
useful data regarding student learning
achievement.
Classroom tests and assessments can
be used for the following instructional
objectives:
1. Pre-testing
2. Test Specifications
Administration of the Test
Maintain a positive attitude for achievement
Maximize achievement motivation
 Equalize advantages to all the students
Rotate distributions
Monitor students continuously
Minimize distractions
Give time warnings properly
Collect test uniformly
Count the answer sheets, seal it in a bag and
hand it over to the quarter concerned.
Scoring Criteria
 In scoring objective tests, each correct answer
is usually counted as one point.
 If some items are counted two points, some
one point, and some half point, the scoring will
be more complicated without any
accompanying benefits.
 When students are told to answer every
item on the test, a student’s score is simply
the number of items answered correctly.
Measurement Scales and Interpretation of Test
• All types of research data, test result data, survey data, etc is called raw
data and collected using four basic scales. Nominal, ordinal, interval and
ratio are four basic scales for data collection. Ratio is more sophisticated
than interval, interval is more sophisticated than ordinal, and ordinal is
more sophisticated than nominal. A variable measured on a "nominal"
scale is a variable that does not really have any evaluative distinction. One
value is really not any greater than another. A good example of a nominal
variable is gender. With nominal variables, there is a qualitative difference
between values, not a quantitative one. Something measured on an
"ordinal" scale does have an evaluative connotation. One value is greater
or larger or better than the other. With ordinal scales, we only know that
one value is better than other or 10 is better than 9. A variable measured
on interval or ration scale has maximum evaluative distinction.
PERCENTILE RANK
 A percentile is a measure that
tells us what percent of the total
frequency scored at or below that
measure. A
percentile rank is the percentage
of scores that fall at or below a
given score.
• Example
• If Aslam stand 25th out of a class of 150 students, then 125 students wereranked
belowAslam.
• Formula
• To find the percentile rank of a score, x, out of a set of n scores, where x is
included:
• Where B = number of scores below x
• E = number of scores equal to x
• n = number of scores
MEASURES OF CENTRAL
TENDENCY
▶Introduction ▶An average is a single value, which
represents the set of data as whole. Since the
average tends to lie in the center of distribution they are
also called measure of central tendency. There are three
methods of measuring the center of any data.
▶Arithmetic mean ▶The Median ▶The Mode
▶Geometric mean ▶Harmonic mean
MEASURES OF
DISPERSION
▶The measure of central tendency does not tell us
anything about the spread data because any two sets of
data may have same central tendency with vast
difference magnitude of variability. Consider two types of
data sets have same mean but different reliability. ▶10,
12, 11, 14, 13 ▶10,
2, 18, 27, 3
 Reporting:
 A document containing information organizedin a narrative, graphic, or tabular
form, prepared on ad hoc, periodic, recurring, regular, or as required basis.
Functions of Test Scores and Progress Reports
The different functions of grading and reporting systems are given as
under:
1. Instructional uses
2. Feedback to students
3. Administrative and guidance uses
4. Informing parents about their children’s performance
TYPES OF SCORE
1.Raw Scores :
A Raw Score is simply the number of questions a student
answers correctly for a test. For example, if a student
responds to 65 items correctly on an objective test in
which each correct item counts one point, the raw score
will be 65.
Standard Scores
 The standard scores indicate a
student’s relative position in a
group. It expresses test
performance in terms of standard
deviation units from the mean
 The mean is the arithmetical
average. The standard deviation
is a measure of the spread of
scores in a group.
GRADING
Grading refers to the process of
using symbols, such as letter to
indicate various types of students
progress (Nitko 2001).

Educational Assessment and Evoluation (8602)

  • 1. REVIEW EDUCATIONAL ASSESSMENT AND EVALUATION (8602) MEASUREMENT, ASSESSMENT AND EVALUATION
  • 2. Concept of Measurement Assessment and Evaluation • Despite their significant role in education the terms measurement, assessment, and evaluation are usually confused with each other. • Mostly people use these terms interchangeably and feel it very difficult to explain the differences among them. • Each of these terms has a specific meaning sharply distinguished from the others.
  • 3. Measurement • Measurement: In general, the term measurement is used to determine the attributes or dimensions of object. For example, we measure an object to know how big, tall or heavy it is. • In educational perspective measurement refers to the process of obtaining a numerical description of a student’s progress towards a pre-determined goal. • This process provides the information regarding how much a student has learnt. Measurement provides quantitative description of the students’ performance for example Rafaih solved 23 arithmetic problems out of 40. • But it does not include the qualitative aspect for example, Rafaih’s work was neat.
  • 4. Testing • A test is an instrument or a systematic procedure to measure a particular characteristic. For example, a test of mathematics will measure the level of the learners’ knowledge of this particular subject or field. • A test is a set of items.
  • 5. Assessment • Assessment: Kizlik (2011) defines assessment as a process by which information is obtained relative to some known objective or goal. Assessment is a broad term that includes testing. • For example, a teacher may assess the knowledge of English language through a test and assesses the language proficiency of the students through any other instrument for example oral quizor presentation. • Based upon this view, we can say that every test is assessment but every assessment is not the test. • In short, we can say that assessment entails much more than testing. It is an ongoing process that includes many formal and informal activities designed to monitor and improve teachingand learning.
  • 6. Evaluation • Evaluation: Hopkins and Antes (1990) defined evaluation asa continuous inspection of all available information in order to form a valid judgment of students’ learning and/or the effectiveness of education program. • The central idea in evaluation is "value." When we evaluate a variable, we are basically judging its worthiness, appropriateness and goodness. Evaluation is always done against a standard, objectives or criterion. • In teaching learning process teachers made students’ evaluations that are usually done in the context of comparisons between what was intended (learning, progress, behaviour) .
  • 7.
  • 8.
  • 9. Assessment for Learning (Formative Assessment) • Checks how students are learning and is there any problem in learning process. it determines what to do next. • Is designed to assist educators and students in improving learning? • Usually focuses on improvement, compared with the student's own previous performance Assessment of Learning (Summative Assessment) • Checks what has been learned to date. • Is designed to provide information to those not directly involved in classroom learning and teaching (school administration, parents, school board), in addition to educators and students? • Usually compares the student's learning either with other students' learning (norm-referenced) or the standard for a grade level (criterion referenced)
  • 10. Test  A test is a device which is used to measure behaviour ofa person for a specific purpose.  Moreover it is an instrument that typically uses sets of items designed to measure a domain of learning tasks.  Tests are systematic method of collecting information that lead to make inferences about the characteristics of people or objects.  teacher prepares tests while sampling the items froma  pool of items in such a way that it represents thewhole subject matter.
  • 11. Taxonomy ofEducational Objectives  Benjamin Bloom established a hierarchy of educational objectives for categorizing level of abstraction of questions that commonly occur in educational settings (Bloom, 1965). The classification is generally referred to as Bloom'sTaxonomy.Taxonomy means 'a set of classification principles', or 'structure'.The followings are six levels in this taxonomy:
  • 13. SOLO Taxonomy  SOLO taxonomy was developed by Biggs and Collis (1982) Stands for Structure of Observed Learning Outcomes
  • 15.  Achievement Tests  Aptitude Tests  Attitude  Intelligence Tests  Personality Tests  Norm-referenced Tests and Criterion- Referenced Tests
  • 16.
  • 17.  Structured Interview  Unstructured Interview  Group Interview  Exit Interview  Depth Interview  Individual Interview  Informal Interview  Formal Interview  Panel Interview  Behavioral Interview  Phone Interview
  • 18. Selection Type Items (objective type) There are four types of test items in selection category of test which are in common use today. multiple-choice, matching, true-false, and completion items. What is a Multiple Choice Question (MCQ)? A multiple-choice question is a type of questionnaire/survey question that provides respondents with multiple answer options. Sometimes called objective response questions, it requires respondents to select only correct answers from the choice options. MCQs are mostly used in educational testing, customer reviews, market research, elections, etc. Although they take different forms depending on their purpose, they have the same structure.

  • 21.  Reliability means Trustworthy, Consistency  A testscoreiscalled reliablewhenwehavereasonsfor believing thetestscoretobestableand objective.  According to Merriam WebsterDictionary: “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.”
  • 22.  Inter-Rater orInter-ObserverReliability  Test-RetestReliability  Parallel-Form Reliability  Internal ConsistencyReliability  Split half Reliability  Kuder-RichardsonReliability

  • 24. Validity  The validity of an assessment tool is the degree to which itmeasures for what it is designed to measure.  The concept refers to the appropriateness, meaningfulness,and usefulness of the specific inferences
  • 27. Factors Affecting Validity  Instructions to TakeATest  Difficult LanguageStructure  Inappropriate Level ofDifficulty  Poorly Constructed TestItems  Ambiguity in ItemsStatements  Length of theTest  Improper Arrangement ofItems  Identifiable Pattern ofAnswers
  • 28. Relationship between Validity and Reliability  Reliability is a necessary requirement for validity  Establishing good reliability is only the first part of establishing validity  Reliability is necessary but not sufficient forvalidity.
  • 29. Planning a Test The main objective of classroom assessment is to obtain valid, reliable and useful data regarding student learning achievement. Classroom tests and assessments can be used for the following instructional objectives: 1. Pre-testing 2. Test Specifications

  • 33. Administration of the Test Maintain a positive attitude for achievement Maximize achievement motivation  Equalize advantages to all the students Rotate distributions Monitor students continuously Minimize distractions Give time warnings properly Collect test uniformly Count the answer sheets, seal it in a bag and hand it over to the quarter concerned.
  • 34. Scoring Criteria  In scoring objective tests, each correct answer is usually counted as one point.  If some items are counted two points, some one point, and some half point, the scoring will be more complicated without any accompanying benefits.  When students are told to answer every item on the test, a student’s score is simply the number of items answered correctly.
  • 35. Measurement Scales and Interpretation of Test • All types of research data, test result data, survey data, etc is called raw data and collected using four basic scales. Nominal, ordinal, interval and ratio are four basic scales for data collection. Ratio is more sophisticated than interval, interval is more sophisticated than ordinal, and ordinal is more sophisticated than nominal. A variable measured on a "nominal" scale is a variable that does not really have any evaluative distinction. One value is really not any greater than another. A good example of a nominal variable is gender. With nominal variables, there is a qualitative difference between values, not a quantitative one. Something measured on an "ordinal" scale does have an evaluative connotation. One value is greater or larger or better than the other. With ordinal scales, we only know that one value is better than other or 10 is better than 9. A variable measured on interval or ration scale has maximum evaluative distinction.
  • 36. PERCENTILE RANK  A percentile is a measure that tells us what percent of the total frequency scored at or below that measure. A percentile rank is the percentage of scores that fall at or below a given score.
  • 37. • Example • If Aslam stand 25th out of a class of 150 students, then 125 students wereranked belowAslam. • Formula • To find the percentile rank of a score, x, out of a set of n scores, where x is included: • Where B = number of scores below x • E = number of scores equal to x • n = number of scores
  • 38. MEASURES OF CENTRAL TENDENCY ▶Introduction ▶An average is a single value, which represents the set of data as whole. Since the average tends to lie in the center of distribution they are also called measure of central tendency. There are three methods of measuring the center of any data. ▶Arithmetic mean ▶The Median ▶The Mode ▶Geometric mean ▶Harmonic mean
  • 39. MEASURES OF DISPERSION ▶The measure of central tendency does not tell us anything about the spread data because any two sets of data may have same central tendency with vast difference magnitude of variability. Consider two types of data sets have same mean but different reliability. ▶10, 12, 11, 14, 13 ▶10, 2, 18, 27, 3

  • 41.  Reporting:  A document containing information organizedin a narrative, graphic, or tabular form, prepared on ad hoc, periodic, recurring, regular, or as required basis. Functions of Test Scores and Progress Reports The different functions of grading and reporting systems are given as under: 1. Instructional uses 2. Feedback to students 3. Administrative and guidance uses 4. Informing parents about their children’s performance
  • 42. TYPES OF SCORE 1.Raw Scores : A Raw Score is simply the number of questions a student answers correctly for a test. For example, if a student responds to 65 items correctly on an objective test in which each correct item counts one point, the raw score will be 65.
  • 43. Standard Scores  The standard scores indicate a student’s relative position in a group. It expresses test performance in terms of standard deviation units from the mean  The mean is the arithmetical average. The standard deviation is a measure of the spread of scores in a group.
  • 44. GRADING Grading refers to the process of using symbols, such as letter to indicate various types of students progress (Nitko 2001).
