Abstract

This study aimed to investigate the effect of applying the Project Based Learning (PjBL) model assisted by animated videos on students’ learning outcomes in atomic structure material at Grade X of SMA Negeri 3 Pematangsiantar. The research employed a quasi-experimental design with a pretest-posttest control group. The participants consisted of two classes: the experimental class, which received instruction using PjBL assisted by animated videos, and the control class, which received conventional instruction. The research instrument was a learning achievement test administered before and after the treatment. Data were analyzed using a t-test and N-Gain calculation. The results indicated that the average pretest scores of both classes were relatively the same. After the learning intervention, the average posttest score of the experimental class increased significantly compared to the control class. The average N-Gain score of the experimental class was in the medium/high category, while that of the control class was in the low/medium category. The t-test result showed a significance value of p < 0.05, indicating a significant difference between the two classes. It can be concluded that the implementation of the Project Based Learning model assisted by animated videos has a positive effect on improving students’ learning outcomes in atomic structure material.

Abstract

This study aims to determine the effect of implementing the inquiry learning model assisted by handout media to improve student learning outcomes in atomic structure material for class X of SMA Negeri 1 Girsang Sipanganbolon. The type of research used is a quasi-experimental study with a pretest-posttest control group design. The research subjects consisted of two classes, namely the experimental class that received learning with inquiry learning models assisted by handout media and the control class that received conventional learning. The research instrument was a learning outcome test given before and after treatment. Data were analyzed using t-test and N-Gain calculations. The results showed that the average pretest scores of both classes were relatively the same. After learning, the average post-test score of the experimental class increased higher than the control class. The average N-Gain score of the experimental class was at 54% in the quite effective category, while the control class was at 21% in the ineffective category. The results of the t-test showed a significance value of p <0.05, which means there was a significant difference between the learning outcomes of the two classes. Thus, it can be concluded that the application of the inquiry learning model assisted by handouts improves student learning outcomes in atomic structure.
