Abstract

This study aims to measure the practicality of physics constructivist modules in the dynamics of rotation and rigid body balance using ADDIE’s model. The module practicality stages are: preparation, research introduction, practicality testing, filling out questionnaires, analyzing and conclusions, revising, and practical. There are 25 students and one physics teacher who asked using a questionnaire with 5 practical indicators, namely: efficiency, presentation of module material, ease of use, conformity with science, and implementation of constructive elements. The results of module practicality testing data analysis showed that the module efficiency level was 65.83 with the practical category, the module presentation rate was 90.16 with a very practical category, the module's ease of use was 86.08 with a very practical category, the degree of conformity with the science was 95,0 with a very practical category, and the level of implementation of constructive elements is 88.8 with a very practical category. Overall, the practicality of constructivist physics learning modules is 85.17 with a very practical category. Based on the results, it can be concluded that the constructivist physics learning module of rotational dynamics and rigid body balance is declared practical to be used as a source of learning for high school physics students.

Abstract

Critical thinking ability is one of the high-level thinking skills that are problem solving skills essentially. The main purpose of this research is to describe the level of students' critical thinking skills in physics subjects at SMAN 8 Pekanbaru. The population in the study were 316 students of grade 11 of SMAN 8 Pekanbaru. Samples were taken by purposive sampling so that a sample of 33 students. The instrument of this research is a test of critical thinking skills which is based on 12 indicators of critical thinking skills. Data was collected by giving a test of critical thinking skills to the sample. Data analysis in this study used descriptive, which provide an overview of the level of critical thinking skills. The results of this study provide information that the average percentage of critical thinking skills students of SMAN 8 Pekanbaru is 50.88% with a moderate level of critical thinking ability.

Abstract

In general, this research aims to produce a valid magnetic induction experimental device as a medium for learning physics in high school. The experimental device consists of experimental equipment and tool usage manual. In particular, this research aims to design, build, and validate devices for magnetic induction experiments on coiled wire as a physics learning media according to the research development steps. Three experts and two physics teachers as users have been involved to provide an assessment of the experimental devices that have been built. Assessment is carried out on the construction and content of the experimental device. The results of data analysis showed that every aspect of the assessment of the experimental tool was declared valid with a very good category (index validity 3.34) and the manual for using experimental tools was also declared valid with a very good category (index of validity 3.47). Thus, it can be said that the magnetic induction experimental device in circular wire is declared valid as a medium for physics learning.
