K, Marthandavarma. (1997). Effectiveness of Instructional Media in Modifying Cognitive and Affective Behavior in Prevention and Control of Acquired Immuno Deficiency Syndrome (AIDs). Unpublished. Ph.D., Education. Bharathiar University, Ghaziabad.
The objectives of the study were: (1) To find out whether the different instructional media viz. audio, video, slides, posters and lecture method are effective in modifying the cognitive and affective behavior among undergraduate students with regard to AIDS epidemic. (2) To find out whether there is any significant difference between lecture method and different instructional media viz. audio, video, slides, posters in modifying the cognitive and affective behavior among undergraduate students with regard to AIDS epidemic. (3) To establish the relative effectiveness among different instructional media viz. audio, video, slides, posters in modifying the cognitive behavior among undergraduate students with regard to AIDS epidemic. (4) To find out whether there is any significant difference among different instructional media viz. audio, video, slides, posters in modifying the affective behavior among undergraduate students with regard to AIDS epidemic. (5) To find out whether there is any significant difference between lecture method and different instructional media viz. audio, video, slides, posters in enhancing retention of cognition and attitude with regard to AIDS epidemic as measured by the retention test. (6) To find out whether the linguistic and cultural background of the instructional media materials on AIDS epidemic have any significant influence in modifying the cognitive and affective behavior among undergraduate students with regard to AIDS epidemic. (7) To develop and standardize a criterion referenced test in AIDS awareness and an attitude scale with regard to AIDS epidemic. (8) To develop an evaluation Performa in validating the media materials developed by different agencies working for the control and prevention of AIDS epidemic.
The hypotheses were: (1) There is significant difference between the means of pre and pot test scores of the students of the groups of lecture method and different instructional media viz. audio, video, slides, posters in cognition of AIDS epidemic. (2) There is significant difference between the means of pre and post test scores of the students of the groups of lecture method and different instructional media viz. audio, video, slides, posters in their attitude towards AIDS epidemic. (3) There is significant difference among lecture method and different instructional media viz. audio, video, slides, posters are effective in modifying the cognitive behavior among undergraduate students with regard to AIDS epidemic. (4) There is significant difference among lecture method and different instructional media viz. audio, video, slides, posters in their effectiveness in modifying the affective behavior among undergraduate students with regard to AIDS epidemic. (5) There is significant difference among lecture method and different instructional media viz. audio, video, slides, posters in their effectiveness in terms of retention of cognition with regard to AIDS epidemic. (6) The effectiveness of an instructional medium is influenced by the linguistic and cultural background of the media material in modifying the cognitive behavior among undergraduate students in AIDS epidemic. (7) The effectiveness of an instructional medium is influenced by the linguistic and cultural background of the media material in enhancing retention of attitude towards AIDS epidemic among undergraduate students as measured by the retention test.
The seven groups of U.G students (n= 245) studying in different colleges in the Coimbatore city were the sample.
The tool of study were: Interview schedule developed by investigator; video, audio materials in AIDS awareness developed by different national and international agencies in the area of prevention and control of AIDS epidemic; Slides and posters dealing with AIDS epidemic developed by Tamil Nadu state cell; Criterion referenced test in AIDS awareness developed by investigator; An attitude scale towards AIDS awareness developed by investigator; and an evaluation Performa developed by investigator.
Pretest-posttest non – equivalent groups design was adopted for the study.
The data were analyzed with the help of t-test.
The findings of the study were: (1) The instructional media are effective in achieving the instructional objectives in AIDS awareness program. (2) The poster as an instructional medium is effective in chancing the attitude towards AIDS epidemic. (3) The different instructional media viz. audio, video, posters, and slides are not effective in changing the attitude towards AIDS epidemic. (4) The different instructional media viz. audio, video, posters, slides differ among themselves in their effectiveness in modifying the cognitive behavior prevention and control of AIDS epidemic. (5) Conventional lecture method is effective than video, audio, and slides. (6) The different instructional media viz. audio, video, posters, and slides differ among themselves in their effectiveness in enhancing retention of attitude towards AIDS epidemic.
