Abstract

Articles This research is a classroom action research (classroom action research). The problem formulated in this study is how to apply online learning of algebra material to students of SMP Class VII MTS Negeri 1 Cimahi using a scientific approach? The aim is to find out the application of online learning of algebra material to students of SMP Class VII MTS Negeri 1 Cimahi using a scientific approach. The hypothesis of this research action is that online learning of Algebra material in class VII MTS Negeri 1 Cimahi can be applied through a scientific approach. This research was carried out on class VII-G MTS Negeri 1 Cimahi in the academic year 2020/2021 with a sum of 32 understudies. The instrument utilized is a learning result test as a trial of understudies numerical class activity research capacities a issues (questions) that attention more on understudies internet finding out about variable based math, before the activity with an underlying test, after the underlying test the educator and understudy perception sheet activity is held. Student learning activity in the first cycle is inclued in the quite active category with an average value of 67.50. The student's score increased by 22.50 from the initial test score of 45.00.

Abstract

This descriptive qualitative research aims to describe the students' mathematical problem-solving abilities on the rectangular material for students of grade VIII SMP. The subjects in this study were students who were selected at random. The technique of collecting data using problem test technique. The type of test in this study is a description test. Most students have not been able to answer the problem maximally. Based on the results of tests that have been done the average percentage of test results about 60% of the description is still low. Still far from the expected researcher is 75%. Data analysis is done to analyze the extent of students' mathematical problem-solving abilities.

Abstract

This study aims to determine the ability of mathematical understanding of class VII students on the material wake flat. The type of research used is a qualitative descriptive research. The subjects of this study consisted of 5 students selected at random. The data collected in the form of written test results as much as 5 points about the ability of students' mathematical understanding. The test results were analyzed according to the students' mathematical comprehension indicator. Data analysis is done to analyze the extent of students' mathematical understanding ability. Based on the result of research that students mathematical understanding ability still not enough in each indicator. From this research can be concluded that students mathematical understanding ability in VII grade in finished the matter of getting up flat is still low

Abstract

This research is based on facts in schools on implementing Kurtilas, students are demanded to think more scientific. Kurtilas is concerned about critical thinking skill of mathematics for solving problems. To gain increased on critical thinking skill of Mathematics, the researcher used Metaphorical Thinking by Deskriptif Kualitatif method. This research was conducted at SMPN 22 Depok and used VII grade as the research samples. The qualitative data was gained from trying out the result of students critical thinking skill of mathematics. The research result shows that Metaphorical Thinking Approach can increase critical thinking skill of mathematics of junior high school students on the triangular material.

Abstract

This research was conducted to determine how the influence of the Think-Pair-Share (TPS) cooperative model on the communication skills of students at MTS Negeri 1 Cimahi, especially in the quadratic function material. Classroom Action Research of often called Classroom Action Research (CAR) is a method  used in this research with the hope that it will provide information or how to improve the abilities of the teacher and student activeness in the learning process. In this research, the subjects were MTSN 1 Cimahi class IX-D students with a total of 33 students. The test is an instrument used in this study, with data processing techniques based on the average percentage of all students scores then compared with the minimum completeness criteria (KKM) in MTSN 1 Cimahi of 75. The result of the test based on the research that has been done, namely the TPS cooperative learning model have an effect on the increase in students comunication skill where there is a significant increase in the pre-cycle result of the students average score of 35,2 then after implementing cycle 1 learning, the average result of student experience an increase of 78. Based on the results obtained, it can be concluded and said that the research that has been done is complete because it has reached the desired target. Classes that have implemented the TPS cooperative learning model can create a more lively classroom atmosphere because it requires students to be active and creative during the learning process. So, this proves that the TPS cooperative model can improve student 'communication skills and students' learning completeness with quadrta function material in class IX-D MTSN 1 Cimahi.

Abstract

This study aims to determine the ability of mathematical connections of students of class VII MTs on triangular and rectangular materials. The type of research used is adapted to the approach that is descriptive research type. The subjects were 5 MTs students. Data collection techniques in this study using test techniques. The results of students' written test are to solve the problem of 5 items. Data analysis is done to analyze students' mathematical connection ability. The average percentage of students' mathematical ability in solving test questions given by the researchers as much as 5 items that are with percentage 36%. So it can be concluded that the mathematical connections of students of MTs on triangle and rectangle materials are still relatively low. This is shown in the test of mathematical connection ability of students have not been able to connect the problem well. Students do not understand how to apply a concept with other concepts, apply the concept to everyday life, apply it to triangle and quadrilateral problem so that students have difficulties in solving problems, difficulties in understanding about making students confused in interpreting the sentence in question.
