Abstract

The research objective is to strengthen student learning outcomes using inquiry-based learning. This type of research is called classroom action research. This study's subjects were 34 students of class X MIPA 4 SMA Negeri 1 Wonomulyo, consisting of 12 boys and 22 girls. The instrument used to measure students' learning outcomes in this study was a multiple-choice test of 50. The indicator that shows the success of the research implementation is that students can achieve a minimum completeness value of 80% at a minimum standard score of 65. Based on the results of the classroom action research that has been implemented In SMA Negeri 1 Wonomulyo, it can be concluded that the application of the Inquiry learning model can improve student learning outcomes in class X MIPA 4 SMA Negeri 1 Wonomulyo. The increase in learning outcomes indicates the research results from cycle I to cycle II; namely, the average value of student learning outcomes increased from 26.47% to 88.23%.

Abstract

This research aims to ascertain how students' critical thinking skills change after being exposed to Problem-Based Learning (PBL). This study employs a quantitative methodology using quasi-experiments. Non-equivalent control groups were employed in this study. The population included 246 students from seven different classes at IPA SMA Negeri 1 Mamasa, who were all in grade XI. This research used a purposive sample of 36 students from the PBL class and 36 students from the control class. The t-test and the Mann-Whitney test were used to analyze the data in this investigation. The t-test results showed that the students' pretest was different (sig. <0.05), so the posttest t-test also showed a difference (sig. <0.05). The Mann-Whitney N-gain test was used to find out whether PBL had a statistically significant impact. The Mann-Whitney test found that the students' critical thinking had improved if the significance level (Sig. of N-gain) was less than 0.05. This study provides evidence that PBL may improve students' critical skills.
