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.

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.

This study aims to determine the improvement of conceptual understanding of physics of class VIII students of SMP Negeri 40 Pekanbaru on the topic of light and optical through learning with cognitive conflict approaches. The type of this research is quasi experiment with population of 172 students of class VIII SMP Negeri 40 Pekanbaru consisted of 4 classes. Two classes were selected to be a research sample based on normality and homogeneity tests on repetition of sound material to obtain experimental and control classes, each of 43 people. The data collected by giving the physics’ conceptual understanding test in Bloom's taxonomy in the form of two tier multiple choice with 14 items. This instrument consists of 7 indicators of conceptual understanding, namely: interpretation, modeling, classifying, summarizing, drawing inference, comparing, and explaining. The result of the research showed that the ability of studens’ concept understanding after the application of learning with cognitive conflict approach was in the good category. The average score of the students’ understanding of the physics concept on the experimental group was higer than the average score of the control group. it can be concluded that learning with cognitive conflict approach can improve conceptual understanding of physics of class VIII SMP Negeri 40 Pekanbaru student on the topic of light and optics.

Science education must be involved in direct experience. Therefore, student must study with finding problem method not talkative method. Education’s module about vibration and wave in curriculum demand, must be accomplish with experient. Unfortunately, this method are difficult to use because the lack of experient tools to produce measured standing waves like velocity, amplitude, period and frequency. The purpose of this research to develop vibration’s simulation experiement tool. This research are belong to developing research type, because it was used to producing some products, and testing the effectiveness of a product. The experiment was following ADDIE model steps, which were consist of 5 steps to follow such as analysis, design, development, implementation and evaluation. The experiment tools could be used after validated by the expert. After the validation finished, the tools can be tested in the field. The validation result from experiment tools and Student Worksheets already passed the validation from the experts. After tested in the student’s groups, the result were positive and fulfill the criteria practical from students view. Therefore, the tools can be used widely to see its effectiveness.

Errors are deviations from things that have been known to be true, errors by students in solving problems can be used by the teacher as a tool in knowing the extent of student ability, so that it can be known the difficulties experienced by students in the learning process. The purpose of this research is to describe the types of errors made by students in solving physics problems on straight motion material at SMAN 5 Pekanbaru. Population in this research were 360 students of class X SMAN 5 Pekanbaru. Samples were taken randomly and a total of 72 students were obtained. This research instrument was in the form of essay questions which were arranged based on the types of errors commonly made by students. Data was collected by giving essay test questions to the research sample. Data analysis in this research uses descriptive analysis with percentage techniques, which provide an overview of the level of errors made by students. Using the six questions that were tested, the most dominant type of error was obtained by students, namely the types of concept errors and data calculation errors, while the types of errors that were least experienced by students were the types of mathematical errors. For this reason, in learning physics on the topic of GLBB in class X SMA N 5 Pekanbaru, it is necessary to emphasize understanding of concepts and calculation of data that is more optimal so that students get better learning outcomes.

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.
