Validity of Computer Based Learning Media to Improve Junior High School Students' Learning Outcomes on Ecosystem Topics

Abstract

The aim of this study was to determine the level of validity of computer-based learning media on ecosystem materials for grade VII junior high school students. The  parameters  measured  were  the  validity  of  the  computer-based learning media from  the  aspect  of material, readability, interaction in media program, navigation button, grafity, readability, and interaction in media program. This study uses developmental stage that followed Dick and Carey (2001) model. The results of the validation by material and design experts were obtained using a questionnaire instrument. Based on the validation result of material expert showed that: (1) Material aspect was 89.28% (2) Readability aspect was 92.85% (3) Interaction in media program aspect was 95.83%. The validation result of media expert showed that: (1) navigation button aspect was 100% (2) Grafity aspect was 90.9% (3) Readability aspect was 96.4% and (4) interaction in media program aspect was 95.83%. It can be concluded that Computer based Learning Media product is feasible to use for learning in ecosystem material based on its validity.
