EFEKTIVITAS PENGGUNAAN VIDEO PEMBELAJARAN TERHADAP MINAT DAN HASIL BELAJAR SISWA PADA MATA PELAJARAN IPA BIOLOGI DI SMP NEGERI 1 SIRENJA

Low levels of students’ interest and learning achievement in Biology,
which are still dominated by conventional learning methods, have
encouraged the need for more innovative instructional media. This study
aims to determine the effectiveness of using video-based learning on
students’ interest and learning achievement in Biology at SMP Negeri 1
Sirenja.This research employed a quasi-experimental method with a
nonequivalent control group design involving two classes: the
experimental class (VIII B) and the control class (VIII A). The
experimental class was taught using video-based learning, while the
control class was taught using conventional learning assisted by
PowerPoint. The research data were collected through a posttest
questionnaire on learning interest and pretest–posttest tests on learning
achievement. The data were analyzed using N-Gain, the Mann-Whitney U
test, and the Wilcoxon Signed Rank Test.The results showed that the
average N-Gain score of the experimental class was 56.75 and the control
class was 55.47, both categorized as moderate. The Mann-Whitney U test
results indicated a significant difference in learning achievement between
the experimental and control classes (p= 0.005). However, the Mann
Whitney U test for learning interest showed no significant difference
between the two groups (p = 0.158). The learning interest of students in
the experimental class was categorized as very high, with a Response
Achievement Level (TCR) of 94.11%.Therefore, it can be concluded that
video-based learning is effective in improving students’ learning
achievement; however, it does not show a significant difference in
students’ learning interest compared to conventional learning in Biology.
