EFFECTIVENESS OF MULTIMEDIA INSTRUCTION IN BETTER ACQUISITION OF CONCEPTS, ACHIEVEMENT AND RETENTION IN BIOLOGY AMONG SENIOR SECONDARY LEVEL LEARNERS
Abstract: Study was undertaken to examine the effectiveness of video based multimedia instruction as a teaching strategy for acquisition of concepts, achievement and retention of biology. Sample of the study comprised of 50 senior secondary students (boys and girls) studying biology as their elective subject in their curriculum, from two schools of Dehradun, assigned into two groups, animation + on screen text + narration (experimental group) or narration + other teaching aids (control group). The pretest, posttest and control group design was adopted. A multiple choice objective test consisting of 53 items, termed as Achievement Test in biology by S.C. Gakhar and Dr. Himadri was used for collecting data. Reliability of the test as reported by the authors is 0.79 and the validity of the test established is 0.92. Analysis of variance (ANOVA) test was used in determining the differences among the two groups. Findings of this study showed that the consistent use of animation + narration + on screen text in the instructional interface resulted in a significantly better learning outcome when compared with those using narration + other teaching aids only. Generally students taught by those using multimedia instruction performed better in achievement test, than their colleagues in conventional teaching method group and had better retention as well.
