The Effectiveness of Web-based Learning Media of Polyhedral for Students Grade 8

Abstract

Students’ difficulties in understanding polyhedral was one of the reasons for developing web-based learning media. This study is aimed at determining the effectiveness of webbased learning media for the students. The subjects of this study were students Grade 8 of SMPN 12 Mukomuko. An experimental method was adopted in this study and samples were divided into control and experimental groups. The control group was taught by conventional learning media while the experimental group was taught by web-based learning media. Pre-test and post-tests were administered to both groups. The findings showed that there is no significant mean difference between students’ outcomes on the pretest and post-tests taught by conventional learning media, but there was a significant mean difference between the students’ outcomes on the pre-test and post-tests taught with webbased learning media. The findings are encouraging and providing some promising directions, however, further study would be needed to determine if the results are due to the web-based approach or due to the teachers’ enthusiasm, the novelty effect known as the Hawthorne Effect.
