Test:
According to Norman E.Gronlund (1985)
Test
is an instrument procedure or systematic procedure for measuring a sample of
behavior (answer the question how well does the individual perform)
According
to Ebel & frisbie (1991):
A
test is set of question each of which has a correct answer, that examine
usually answer orally or in writing
Measurement:
According
to Norman E.Gronlund (1985)
Measurement
is the process of obtaining a numerical description of the degree to which an
individual process particular characteristics.
Assessment:
According
to Murry print (1993)
Assessment
involves the interpretation of measurement data. It makes sense of the data
collected on student performance.
Evaluation:
According
to Mehrens & Lehmann (1984)
Evaluation
is the process of delineating and providing useful information for judging
decision alternatives.
Roll and
Need of Assessment & Evaluation in Educational Process
Assessment
and evaluation play a pivotal role in teaching learning process following
points may describe the role of assessment and evaluation in educational
process.
·
Guiding and counseling
·
Judged different capabilities
·
Use in administration
·
Improve learning: evaluation procedures can
contribute in improvement of learning.
·
Improves instruction: information gathered through evaluation
technique can be used to asses and Improve instruction.
·
Promotion and next class: on the basis of
mark and grades, pupils are promoted in next class.
·
Motivation and competition: by knowing their
status or performance students are motivated to work more and complete the
follows.
Types of Assessment and Evaluation:
Ø Formative Assessment
Ø Summative Assessment
Ø Diagnostic Assessment
Ø Continuous Assessment
Techniques of Assessment:
Following
are the technique of assessment and evaluation:
Observation
, interview , questionnaire , test , attitude scale , socionmetric technique ,
check list , project technique , rating scale , anecdotal records.
Types of Tests:
A test
can be divided in to two categories.
1.
Objective
type test:
A. Supply
type test: short answer, completion.
B. Selection
type test: True/Falls or alternative response, matching the columns,
multiple-choice questions.
2.
Essay
type test:
A. Extended
response
B. Restricted
response
Standardized Test:
Standardized
test refers to test that
·
Has been expertly developed
·
Includes clear instruction for uniform
administration and scoring
·
Provides tables of norms for score
interpretation
Teacher Made Test:
Test
development by the class teacher in order to assess the achievement of the
students in particular subjects is called a teacher made test
Criterion Reference Test:
According
to Norman E.Gronlund (1985)
“CRT” Is
a test designed to provide a measure of performance that is interpretable in
terms of a clearly defined and delimited of learning tasks.
Norm Reference Test:
According
to Norman E.Gronlund (1985)
“NRT” is the test designed to provide a measure of
performance that is interpretable in terms of an individual’s relative standing
in some knowing group.
CHARACTERISTICS
OF GOOD TEST
1. Validity
2. Reliability 3. Usability 4. Objectivity
1. Validity:
Validity is the degree to which the test
measure what is supposed to measure.
Types of Validity:
1. Content
Validity: content validity is the degree to which a
test measures an intended content area.
2. Construct
Validity: construct validity is the degree to which
the test measures an intended hypothetical construct.
3. Concurrent
Validity: concurrent validity is the degree to which
the scores on a test are related to the scores on another already established
test administered at the same time.
4. Predictive
Validity: predictive validity is the degree to which a
test can predict how well an individual will do in future.
Factors Affecting Validity:
·
Unclear direction
·
Reading vocabulary and sentence structure too
difficult
·
Inappropriate level of difficulty of the test
items
·
Poorly constructed test time
·
Ambiguity
·
Test items inappropriate for the outcomes
being measured
·
Test too short
·
Improper arrangement of items
·
Identifiable pattern of answer
2. Reliability
Reliability is the degree to which a test
consistently measures whatever it measure. A reliable test gives the same
scores when administered and read ministered while an unreliable test does not
give the same scores.
Types of Reliability:
1. Test
retest reliability: which scores are consist over time
2. Equivalent
forms reliability: equivalent forms of a test are two tests that are identical
in every way except for the actual items included.
3. Spilt
half reliability: split half reliability is determined by establishing the
relationship between the scores on two question halves of a test administered
to a group at one time.
Factors
Affecting Reliability:
·
Length of test
·
Spread of scores
·
Difficulty of test
·
Objectivity
3. Usability:
It
is the characteristics of a test to fulfill following practical consideration.
A. Time
of administration: a safe procedure is to allot as much time as is necessary to
obtain valid and reliable rules.
B. Ease
of administration: a test will be easy to administer when direction will be
simple and clear.Sub tests will be few. Time of test will be suitable
Ease of Scoring:
Those
tests are favored that offer ease and economy of scoring without sacrificing
scoring accuracy.
Ease of Interpretation:
When the results are present to the pupils or
parents, ease of interpretation and application are especially important. Availability of equivalent forms: equivalent
forms of a test measure the same aspect of behavior by using test items that
are alike in contents difficulty level and other characteristics.
Cost of
testing: testing should be economical but sacrificing valid and reliable test
of being high cost and selecting cheaper test is false economy.
4.Objectivity:
The objectivity is a test refers to the degree to which
equally component scores obtained the same results.
Table of specification:
A sample of pupil performance is more likely to be
representative if a set of specification is used in planning the test. The
specification defines and limits the achievement domain to be measured and
describe the sample of test items to be prepared. One form of specification is
a two-way chart, called a table of specification. Table of specification
involves:
(1) Obtaining
the list of instructional objectives
(2) Outlining
the course content
(3) Prepare
the two-way chart that relates the instructional objectives to course content
Administering Of Test:
Physical condition: physical condition consist of
·
Adequate
work space
·
Proper
light
·
Ventilation
·
Comfortable
temperature
Psychological Conditions:
Provision of conductive psychological
atmosphere is of great importance which mean atmosphere free of threatening and
warning pupils like:
·
Threatening pupils which tests if they do not
behave
·
Warning pupils to do their best “ because
this test is important”
·
Telling pupils they must work fast in order
to complete the test on time
·
Threatening dire consequence if they fail the
test
·
Principle of Administering
Of Test:
·
Don’t
talk unnecessarily before the test
·
Keep
interruption to a minimum during the test
·
Avoids
giving hints to pupils who ask about individual items
·
Discourage
cheating, if necessary
·
Who
can score of objectives tests be improved? Scoring of objectives tests can be
improved by using :
·
Scoring key when separate answer sheets are provided
·
When
separate answer sheet are using , a scoring stencil is more convenient
·
When
there is no scoring key, mark tick ( √ ) for correct , mark cross ( x) for wrong and
mark (0) for committed
·
Score=
total number of items-wrong or missing items
·
Count
and write the score on each page separately and then add all
·
Mark
on for each items
·
Inform
pupils for using guessing correction formula
·
Function
of marks and progress of reports:
·
These
facilities the pupils learning and development
·
There
is need for a periodic summary of progress
·
Reports
also give them a basic for checking the adequacy of their own self-estimates of
learning progress.
Types of Marking and Reporting:
The
traditional method of reporting pupil progress which is still in wide use
today, is to assign letter grad e.g ( A,B,C,D,F) single number e,g (5,4,3,2,1)
to represent a pupils achievement in each subject.
Following are the types of marking and
reporting;
·
Traditional
marking system
·
Pass-
fail system
·
Checklist
of objectives
·
Letters
to parents
·
Parent
teacher conferences
·
Multiple
marking and reporting systems
