Abstract

This study aims to determine the effectiveness of inquiry-based learning student worksheets (LKS) in improving students' critical thinking skills on buffer solutions. One student from a class of 27 in grade XI at SMAN 1 Bireuen, Aceh, Indonesia, was selected as the sample for this research, which employed a qualitative descriptive approach. Data were collected through validated multiple-choice tests. The results indicate that inquiry-based LKS enhances students' critical thinking skills in four key aspects: questioning and answering, observing and evaluating observation reports, making decisions and considering outcomes, and drawing inductions and evaluating inductive conclusions. However, students exhibited relatively weak skills in formulating questions. Inquiry-based learning enables students to actively participate in the learning process, conduct experiments, and solve problems independently. Previous research has shown that inquiry-based learning is effective in developing critical thinking skills.

Abstract

The objective of this study is to enhance the understanding of elementary school students at SDN Lamklat, Aceh Besar, regarding fundamental football techniques, including dribbling, kicking, and passing. A Classroom Action Research (CAR) approach was employed, conducted in two cycles comprising planning, implementation, observation, and reflection phases. The study involved 25 fourth-grade students as participants. Data were collected through skill tests, questionnaires, and observation sheets. The findings revealed a significant improvement in the mastery of basic football techniques. In the first cycle, 65% of students achieved satisfactory mastery with an average class score of 70. By the second cycle, 85% of students reached satisfactory mastery, with an average class score of 85. Practice- and game-based learning effectively boosted students' motivation and skills. Therefore, teaching fundamental football techniques using more interactive and contextual methods positively impacts student abilities. Similar methods are recommended to enhance skills in other sports disciplines.
