Tare, Jyoti. (2001). A Study of the Effectiveness of Branching Variety of Programmed Instructional Material as Diagnostic and Remedial Tool in Chemistry for Secondary Classes in Jabalpur Division. Unpublished. Ph.D., Education. Rani Durgavati University, Jabalpur.
Objectives of the study:1. To compare the achievements of the students of urban and rural areas of Jabalpur Division by the traditional method of teaching with that of studying through branching frames of programmed learning in Chemistry Subject.2. To diagnose the weakness of the students of urban and rural areas with the help of PLM.
280 students were selected from different Government Higher Secondary Schools ofurban and rural areas of Jabalpur Division.
A branching programme was developed on Atomic Structure and Chemical Bonding and pre-test and post-test were constructed by the investigator.
Experimental and Control Group Design was used for the purpose of this study.
ANOVA and t-test were used for data analysis.
Findings of the study: 1. The achievement of the experimental group was found significantly greater than the achievement of the control group.2. The achievement of the urban girls through PLM was found significantly higher than that of the urban boys.3. No significant difference was found in the achievement of boys and girls of rural areas in the post-test on atomic structure and chemical bonding.4. 135 boys out of 180 and 64 girls out of 99 wanted to continue the study with the PLM on both the topics.5. The weakness of individual students were diagnosed and removed when branched frames on both the topics were administered.
