Abstract

Mathematics is a symbolic language of its characteristics is to use deductive reasoning and inductive reasoning methods. In the teaching of mathematics each subject is a unit so that the mastery of one subject is a support to learn the next subject. Similarly, the ability of students in carrying out calculating operations in mathematics lessons in developing students' critical thinking skills. To perform calculating operations on the right learning requires the right learning model and teaching materials. Therefore, the right learning model in cultivating students' critical thinking skills is a project-based learning model. This research aims to find out the ability to think critically through project-based learning models on the material of the theorem theorem phytagoras of students in class VIII of State Junior High School 5 West Leihitu District. The type of research used in this study is qualitative descriptive. The process of taking subjects is based on the highest value of group work on LKS. From the results of the group's work, 3 students were taken from the total number of students, namely 30 people. The instruments used in this study were researchers, tests and interviews. The data analysis techniques used follow concepts developed by Miles and Huberman, namely data reduction, data presentation, and inference. The results of the data analysis obtained that the critical thinking skills possessed by each student vary. From the results of interviews with 3 subjects, it is known that sl subjects meet 4 indicators of critical thinking skills used in this study, namely providing simple explanations, building basic abilities, making conclusions, and providing advanced explanations. The AH subject meets two indicators: providing simple explanations and building basic skills. While the subject of RK only met one indicator used in this study, namely building basic capabilities in the problem-solving process.

Abstract

Video media has considerable potential if used as a learning medium that allows students to directly observe the real form of objects. This study aims to determine the improvement of mathematics learning outcomes through a contextual approach to the volume material of building space using a video compact disc. The type of research used is classroom action research and consists of four stages, namely planning, action, observation, and reflection and the number of subjects amounted to 30 people. The instruments used are tests and observation sheets. Tests are used to determine student learning outcomes and observation is used to determine student activities in the learning process. Data analysis techniques are used descriptively. The results of data analysis obtained that the application of contextual approaches can improve student learning outcomes. This result is intended by increasing test results in cycle I, and cycle II which is carried out with a contextual approach. If in cycle I the learning process has not taken place optimally because students are still not serious in learning and class management is still lacking by the teacher, in cycle II the learning process that takes place is in accordance with the learning steps and students can discuss with their friends in class
