The Effect of The Problem Based Learning Model With Animated Video on Students' Hots Ability on The Material On Human Movement Systems

Abstract

This study aims to investigate the effect of the Problem-Based Learning (PBL) model assisted by animated videos on students' Higher Order Thinking Skills (HOTS) in the topic of the human movement system among eighth-grade students at SMP Negeri 12 Medan. The research employed a pretest–posttest control group design with a sample of 60 students, divided into an experimental class (30 students using PBL with animated videos) and a control class (30 students using expository learning). Improvement in students' HOTS was measured using the N-Gain score from the average posttest results. The N-Gain score for the experimental class was categorized as moderate. The data were analyzed using a one-tailed t-test. The average posttest score of the experimental class was 84.50, compared to 67.50 in the control class. Hypothesis testing revealed tcount=2.32 and ttable=2.045, indicating that tcount > ttable. There- fore, it can be concluded that students taught with the Problem-Based Learning model assisted by animated videos achieved significantly higher HOTS compared to those taught with expository learning.
