PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) TERHADAP AKTIVITAS DAN HASIL BELAJAR KIMIA SISWA KELAS XI IPA SMA NEGERI 8 MEDAN T.P 2024/2025

Abstract

The purpose of this study is to determine the influence of the Problem Based
Learning (PBL) learning model on the activities and learning outcomes of students
in grade XI of Science at SMA Negeri 8 Medan T.P 2024/2025 on colloid system
materials. The sample of this study is 36 students in class XI-8 as an experimental
class using the Problem Based Learning learning model and 30 students in class
XI-2 as a control class using the conventional model. Data collection techniques are
carried out through observation, objective tests, and documentation. The research
design used was Two Groups (Pretest and Posttest). The results of the study show
that there is a positive and significant influence of the Problem Based Learning
learning model on the activities and learning outcomes of chemistry students in
grade XI Science of SMA Negeri 8 Medan T.P 2024/2025. This can be seen from
the average value of activities and learning outcomes of the experimental class,
which is 82.29 and 81.67, while the average activity and learning outcomes of the
control class are 74.17 and 79.17. 2. Then, tcalculated for the learning activities of the
experimental class is 11,262 > ttable, which is 1.6696. Likewise, for the learning
outcomes of the experimental class, the calculation is 3,439 > ttable, which is 1,669.
