Developing Comic of Human Skeletal System and Its Potential in Improving Junior High School Students' Learning Achievement

Learning media plays an important role in increasing students' interest and motivation in science. This study aimed at analyzing the feasibility of comic as a learning media for human musculoskeletal system topic as well as analyzing its potential in improving the learning outcomes of eighth graders. The Gall and Borg [1] development model was chosen as the basis of the study procedure. Interview sheets, validation questionnaires, student response sheets, and test sheets were used as the instruments in data collection. The comic validation results gained from the both content and media experts were 82% and 80% respectively, which means that the comic developed was categorized as ‘good'. Moreover, the results of pilot test done showed that the students' learning outcomes increased from 69 to 95, while the students' response has reached 96.77%. In addition, the large-scale trial results indicated that the students' learning outcomes have significantly increased (Z = 7.296, p = 0.000). The findings in this study indicate that the comic learning media developed was potential in improving the quality of biology learning process in junior high schools.
