Abstract

This study used a mixed qualitative and quantitative approach with 25 purposively selected students divided into two experimental classes. Experimental Class 1 learned acid-base material using Problem Based Learning (PBL), while Experimental Class 2 used Discovery Learning (DL), both assisted by learning videos. Pre-tests and post-tests were conducted to measure learning outcomesand motivation. Results showed average post-test scores of 82.00 for PBL and 76.40 for DL. Students with high motivation scored higher in both models (PBL: 74.27; DL: 74.36) compared to those with low motivation. A significant linear relationship was found between motivation and learning outcomes in both learning models.
