This research is motivated by the low ability of mathematics understanding of junior high school students, with the aim of the study is to examine the achievement, improvement, implementation, and difficulty of mathematics understanding ability of junior high school students through learning using Geogebra-assisted scientific approach. The method of this research is an experimental method with two class groups namely experimental class and control class. The population of this research is all junior high school in West Bandung Regency, randomly selected and selected SMP Krida Utama Padalarang. Samples were taken randomly class VIII chosen D as an experimental class, and class VIII C as control class. The experimental level received learning with the Geogebra-assisted scientific approach, and the control class gained regular learning. The results showed that the achievement and improvement of the ability of mathematical understanding between students who received learning with scientific approach assisted Geogebra software better with students who get regular learning. Learning with Geogebra-assisted scientific approach can be implemented in the experimental class by the steps of the scientific method of observing, asking, exploring, associating, and communicating.

This study aims to analyze the critical thinking skills of junior high school students on Pythagoras material. Subjects in this study are students of class VIII-F in SMP Negeri 1 Ngamprah with the number of students 37 people. The method used in this research is qualitative descriptive. This type is chosen because it aims to describe the skills of students in solving problems of mathematical critical thinking independently. The research phase is divided into three, namely planning, implementation, and reporting. The technique of collecting data in the form of test. Data analysis techniques based on indicators of mathematical critical thinking skills that has been determined by researchers include: (1) identifying the concepts used in problem solving, (2) formulating an action (strategy, tactics, or approach) in solving problems, (3) providing arguments or reasons for answering and solving problems, and (4) evaluating evidence or decisions taken in solving the problem. The results obtained quantitatively show that the level of mathematical critical thinking skills of students in SMP Negeri 1 Ngamprah in solving the problems on Pythagoras material still falls into the low category. The evidence from the percentage of each indicator with the highest rate of only 61%. Some factors influence the level of students critical thinking skills, including the preparation of incomplete and appropriate strategies, provide arguments without showing the truth, and the students' accuracy in working on the questions.
