The main purpose of this research was to know the level of understanding of students’ concepts in the sound wave and light waves material in class XI students of senior high school in the sub-district of Tampan, Pekanbaru. This research is survey research. The population in this research were all students of class XI of state Senior high schools in the Tampan sub-district of Pekanbaru, while the research sample numbered 65 students. The research instrument was in the form of concept understanding tests that were compiled based on indicators understanding the concepts of translation, interpretation, and extrapolation. The questions used were in the form of a written test in the form of multiple-choice totaling 26 items. The results of the answers to the questions given are then analyzed using descriptive analysis. The results of this research provide information, that the level of concepts understanding of class XI students in high schools throughout the sub-district of Tampan, Pekanbaru in physics lessons on sound wave material and light waves are in the very low category for the three indicators of translation, interpretation, and extrapolation. Therefore, a learning strategy is needed that is able to overcome the low understanding of the student's concepts.

Critical thinking is one of the high-level thinking stages that can be interpreted as a process of thinking precisely, directed, reasoned, and reflective in decision-making that can be trusted. This study was aimed to determine the improvement of critical thinking skills toward Guided Discovery Learning model of grade VIII students at MTs Al-Huda Pekanbaru on light material. The type of research used was experimental research. Descriptive analysis was used to analyze the data. This analysis gave the description about influence of Guided Discovery Learning model toward student's critical thinking ability. The subjects of this study were 58 students. The data was collected based on critical thinking skill's test result which consisted of 15 essay questions for 5 indicators after Guided Discovery Learning model was applied on experiment class and conventional model on control class. Mean score of sudents' critical thinking ability on experiment class was 78.45 which was in a high category and average score of students' critical thinking skill on control class was 70.52 which was in low category. Based on the result of students' critical thinking skill, it can be concluded that there was an improvement of critical thinking ability after guided discovery learning model was applied by 11.24% compared to conventional learning model.

Science literacy is the capacity of individuals to use scientific knowledge to be able to make the right decisions related to nature and human interaction. This study aims to produce test instruments based on scientific literacy on energy matter in living systems. The research method used is Research and Development (R & D) using the ADDIE (Analysis-Design-Development-Implemtation-Evaluation) development model. The stages of the study began with an analysis of the problems of science literacy skills of Indonesian students, then proceeded to develop indicators of questions based on the PISA 2015 indicators. After the indicators were developed, they were followed by making questions and question validation by 3 expert validators. Questions that have been validity tested are limited to 31 students. Data obtained from logical validity and limited trials. Then the data is analyzed descriptively. The results of the analysis of the data obtained are, the validation assessment of science literacy-based test instruments on energy material in living systems by experts is 79.39% with valid validity levels, while the assessment of limited trials is obtained from the validity of 17 questions declared valid and have value reliability of 0.6 with moderate reliability.

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.

This study wasaimed to describe the level of student scientific consistency and representation consistency of class X SMA Negeri 8 Pekanbaru on rectilinear motion kinematisc material. The type of research was survey research. The subject of this research were 70 students. The data collection of this research used test, instrument of research used scientific consistency and representation consistency test the form of objektive matter which consist of 21 question wiht seven themes, each theme consist off three question with the same concept but presented in different representatiton. Descriptive analysis was used to analyze the data which showed the level of scientific consistency and representation consistency. The results showed that thepercentage of student at each scientific consistency level was 14.29% for consistent scientific, 20.00% for moderately consistent scientific and 65.71% for inconsistent scientific, while overall the students were at inconsistent levels for scientific consistency or that can be said they have no consistency scientific. For representation consistency, the percentage of students at each successive level was 17.14% for consistent representation, 28.57% for moderately consistent representation and 54.29% for inconsistent representation, while overall students were at moderately consistent representation level, mean that studentshave consistency representation.
