Penerapan Pembelajaran Berbasis Praktikum Sederhana untuk Meningkatkan Hasil Belajar Siswa pada Materi Kesetimbangan Kimia

Abstrak

This study was conducted to measure the effectiveness of a simple laboratory-based learning method in improving the learning outcomes of students in class XI-1 at State Senior High School 9 in Yogyakarta. The focus of this study was on the topic of chemical equilibrium in the chemistry curriculum. This study employed a pre-experimental method with a one-group pretest-posttest design. All 36 students in class XI-1 served as the study population and sample. Data were obtained from tests administered before (pretest) and after (posttest) instruction, with a mean pretest score of 58,41, which increased to mean posttest score of 81,66. In this study, the validity and reliability of the multiple-choice test instrument were also assessed. The results indicate that the instrument used is valid and suitable for research, and its average reliability coefficient reached 0,7, indicating high reliability. Data analysis utilized a t-test to test the formulated hypotheses. The calculation results showed that the calculated t-value was greater than the critical t-value (25,57 > 2,03). This indicates that the average posttest score increased significantly compared to the average pretest score. In conclusion, the implementation of simple laboratory-based learning has a positive effect on improving student learning outcomes in chemical equilibrium material.
