3. DEFINITION
3
 A Computer-Based Assessment (CBA), also known
as Computer-Based Testing (CBT), e-assessment,
computerized testing and computer-administered
testing, is a method of administering tests in which the
responses are electronically recorded, assessed, or both.
As the name implies, Computer-Based Assessment
makes use of a computer or an equivalent electronic
device such as a cell phone or PDA. CBA systems enable
educators and trainers to author, schedule, deliver, and
report on surveys, quizzes, tests and exams. Computer-
Based Assessment may be a stand-alone system or a part
of a virtual learning environment, possibly accessed via
the World Wide Web.

Type of evaluation:
 Objective type tests (on the base of comparing
answers with an etalon)
 Recognition level
 Reproduction level
 Heuristic (creative) level
 Subjective type tests (free form of answering –
problem solving, practice e tc.)

10. CRITICAL PROPERTIES
10
 VALIDITY– equivalence of test exercises to
learning content and test results.
RELIABILITY.
Test is reliable if we can see the same results for
each person after second time of the same testing

11. Rules for test developing
11
 Reasonable choice of scale for evaluation test results
 The quantity of exercises should be 30–40 for
science subjects and twice more for humanitarian
ones
 The quantity of exercises in a data base should be 10
times more then in one test (so 300-400 exercises).

12. Rules for tests giving
12
 Student should be informed about the quantity of
exercises and time limit
 Student should have opportunity to do
demonstrative test at least one time before starting
the attestation test. It is important for introduction
the interface of testing program and ways of
answering.

13. Rules for tests giving
13
 During testing there should be only one exercise on
the screen
 The way of answering should be simple and
comfortable

14. Students opportunities during testing:
14
 To submit each answer;
 To correct answers before submission the answer;
 To skip exercises more then one time;

15. Students opportunities during testing:
15
 To click the instruction for answering anytime;
 To see the result immediately after finishing test.

16. Rules for test designing
16
 The main part of exercise is one sentence no
more then 7-8 words
 All the answers for one question should be
approximately the same size
 All the distractors should be the same for
student who does not know the correct answer
 There should not exist partly correct distractors
which can become the correct answer in some
conditions

17. Requirements to test exercises
1718
1111
 The content of exercise should not contain
repetitions or double negation
 Each test exercise should be related with concrete
fact, principle or skill
 Test exercise should not contain subjective opinion
of creator

18. Requirements to test exercises
18
 There should not be unintentional hints or slang
words
 The time of showing exercise on the screen is 1,5
- 2 minutes.
 In each open exercise the quantity of distractors
should be 4 or 6, but in exercises for
correspondence they should be twice more

19. Requirements to test exercises
19
 Test exercise should be a narration (questions why,
how, which etc. are not used).
 Do not use words like “sometimes”, “often”,
“always”, “big”, “small”, “many” etc.

20. Requirements to test exercises
20
 The key word or definition should be in the first
part of an exercise
 It is better to make long exercise and short
distractors than contrary
