Abstract

The importance of critical thinking skills for students in the study of chemistry, it is necessary to appropriate learning models that can involve students directly in making students active learning and improve students' critical thinking skills. One model that can be applied is discovery learning model learning. The purpose of this study was to determine the increase in critical thinking skills of students learning through discovery learning. This study was an experimental study design with nonequivalent pretest-Posttes Control Group Design. The subjects of the study involves two classes of experimental class and control class. Data collection instruments in the form of test critical thinking skills in the form of matter description. Statistical testing using independent sample t-test were previously tested for normality, homogeneity test at the 0.05 significance level. The results showed no difference in the increase in critical thinking skills in each of the indicators of critical thinking skills.Keywords: Discovery learning, critical thinking skills

Abstract

The current research aims to: 1) determine the difference between self-efficacy (SE) and critical thinking skills (CTS) of pre-service chemistry teachers who were taught using the PjBL model; and 2) know how much the implementation of the PjBL model influences their self-efficacy (SE) and critical thinking skills (CTS). This experimental research was conducted through a quasi-experimental nonequivalent pretest-posttest control group design. The Cronbach's alpha coefficient value test for the validation of the instruments resulted in SE α = .86 and CTS α = .85. Manova test with a significance level of .05 was also performed to analyze the data. The results indicated: 1) there were significant differences in self-efficacy (SE) and critical thinking skills (CTS) before and after the implementation of the PjBL model, and 2) there was a significant effect of implementing the PjBL model on self-efficacy (SE) and critical thinking skills (CTS) with the contribution of the PjBL model of 35%. These results contribute to educational literature as an alternative solution for lecturers to apply the PjBL model in chemistry education learning in universities. Considering the characteristics of the learning material, students, and environmental conditions will maximize teamwork cooperation by using project-based activities to develop students' 21st-century skills.

Abstract

This study aims to develop a feasible and effective e-learning chemistry book integrated with Sasak’s local wisdom to enhance students’ science, technology, engineering, and mathematics (STEM) skills. The research adopts a development approach utilizing the ADDIE model include analysis, design, development, evaluation and implementation. Product trial on chemistry education students at UIN Mataram employing a quasi-experimental pre-test and post-test control group design. The study reveals that the e-learning chemistry book, integrated with Sasak local wisdom, achieves an Aiken’s validity coefficient of 0.890, an intraclass correlation coefficient (ICC) value of 0.810, and a Cronbach’s alpha reliability value of 0.875. Furthermore, the results of the independent sample T-test indicate a significance value of 0.01, which is less than α (0.05), affirming that the e-learning chemistry book integrated with Sasak local wisdom meets valid and reliable criteria and is declared effective in enhancing students’ STEM skills
