Unit–29: Development of Programmed Study

(2) Program—With the help of experts, it is seen that the original Draft techniques of instruction in the program, Notes
as Compositions, Frames give proper order or style of the original draft—language is not an error.
(3) Language—Prepared with the help of experts in the Draft grammar mistakes, Spelling errors and

inappropriate and ambiguous language, is used to detect and fix. Instruction instructions obscurity,
language uncertainty of the shortcomings and the inappropriateness of examples given are correct
and original Draft the necessary changes are made.

29.4 Testing and Evaluation

This last task is the creation of the programmes, prepared under the revised Draft program is tested and
evaluated. Following activities are conducted in—
(1) Individual Tryout—This program is administered at 4-5 students and it is detected in the fi nished

program Draft position, size, language, suffixes, and memorandum relating to Upakramk - what
are drawbacks. In addition, students’ responses are noted and the necessary changes are made in
the cleanup programme.

(2) Small Group Tryout-converting and re refined program—Students Group is to be administered.
Necessary changes in the Draft and the students are asked for suggestions for improvement. The Views
and taken note of the time and re-revision and refinement of all these programs is on the ground.

(3) Field Tryout—Program for the finalization of the program, a representative sample re-administered
to the 10 to 20 students’ reactions have been extensively and made suggestions based on the revised
draft again. This test is based on the programmes relevance and validity is installed.
(4) Evaluation—Based on the data obtained from field tests to evaluate the following things is—

(i) Error Rate—The following formula is used to determine—
Total No. of Errors × 100
Programme Error Rate = ..........
(In percentages)

Total No. of Responses × No. of Students
Error rate of 5%–10% linear program and can be up to 20% Branched programmes.

(ii) Programme Density—The difficulty level of the programmes is detected. The following formula
is used to determine -
Total No. of Different Types of Responses in a Programme
TTR (Type Token Ratio) = ..........
Total No. of Responses Required in a Programme
TTR value should be between 0.25 to 0.33.

How the programme rate is determined?

(iii) Sequence Progression—Sequence Progression can be seen with the help of Scalogram. Criteria
Scalogram table is created on the basis of test scores. The table Based on the sequence of program
flow is seen. If you look at the table shows that in the course sequence If the system is not fair

to have to try to improve the program.
