Thinking creative is a thinking process which to produce kinds of idea possibility and the way widely and many to completed a problem, when applied thinking creative, will produce many useful ideas to find the resolver. Creative connects with finding something, about the thing that produces something new with using something that has been there. Research methods will use is descriptive qualitative. As for the sample in this research are seventh grade with high ability, medium and low in Kabupaten Bandung Barat. For the instrument test thinking, the creative ability will deliver to students are five question and following with interview in each student. Then, the results obtained was the level of their thinking creative ability according to their writing test and results of the interview with the low-level students. Next, this research is parts of my research paper will be careful.

The purpose of this research is to develop local instruction theory on triangular and quadrilateral material and examine the improvement of mathematical representation ability by using local instruction theory. The method used in this research is design research method which includes three stages, namely: preliminary design, design experiment and retrospective analysis. The instruments in this study were in the form of tests and non-tests, where the tests used were aimed to determine the improvement of students' mathematical representation ability while non-tests such as interviews and observations were used to develop the local instruction theory. Subjects in this study were 40 junior high school students. The final result of this research is the development of local instruction theory teaching materials that can be used by the teacher to be used as a guide in teaching and the ability of students' mathematical representation in triangular and quadrilateral material is sufficiently increased

This study aims to analyze connection self-efficacy toward the ability of critical thinking on the material of circe of junior high school students. This research method using the qualitative descriptive method. This research is conducted in SMP Negeri 9 Cimahi in Grade IX of the academic year 2017-2018. The population of this study is the students of class IX SMP Negeri 9 and the subject of the research is all the students of class IX-A that consist of 34 students. To obtain the research data used the instrument in the form of test description and questionnaire self-efficacy. The results of the research concluded: (1) the level of students' mathematical critical thinking ability in the problem solution is still low; (2) students' difficulties, in general, have not understood the problem and the preconception is still low; (3) students have not embedded the sense of learning independently; (4)there are connection which is significant between self-efficacy toward mathematics critical thinking.

This study aims to examine the scenario and implementation of online learning, the reaction of teachers and students to learning, the difficulties felt by students in completing the problem, as well as the obstacles experienced by teachers when doing online learning material system of linear equations two variables using CTL approach. This study is a qualitative descriptive research. This study was conducted on 20 students of SMP Plus Darul Amanah Ciwidey. The results of the study went as planned, the teacher's reaction when the learning process got a score of 94% which included very good criteria, it can be seen from the results of teacher observation sheets carried out each learning meeting, the student's reaction to learning got an average score of 71% with a very good category. The difficulty experienced by students in working on a system of linear equations of two variables lies in the difficulty of skills, concepts, and principles. The obstacles experienced by teachers when carrying out learning are varied such as students who do not have internet quotas, expensive internet payments, signal constraints, lack of student motivation, and lack of supervision from parents during the learning process.

This study intends to determine the feasibility and practicality of worksheets for students of Social Arithmetic material using the Liveworksheets-assisted Problem Based Learning learning model. The development model used is the 4D method which is limited to the third step which includes: define, design and develompment stages. Feasibility test data and practicality of LKPD were collected through observation and questionnaires. The feasibility of LKPD is analyzed based on the results of validation by experts and the practicality of LKPD seen from student questionnaire responses. The subjects of this study were50 students on a small scale and 30 students on a broad scale .The results of this study show that the LKPD tested is very feasible and very practical to use for learning. This is seen based on the results of validation by experts who get an average of 95% with very valid categories and the practicality of LKPD taken from student response questionnaires with a percentage of 8,567% on a small scale and 88,33% on a broad scale. This shows that LKPD uses the Liveworksheets-assisted Problem Based Learning learning model on Social Arithmetic material is very valid and practical to use.

This research aims to find out and analyze the media visual basic for application (VBA) Excel in improving students' reasoning abilities and active learning through learning models problem-based learning. The research method and design used is a quasi-experimental design nonequivalent control group. The subjects in this research were class VIII students at one of the state junior high schools in the West Bandung Regency area. The data collection technique used in this research is data pretest, posttest, and N-Gain mathematical reasoning abilities and student learning activity questionnaires. Then the data is processed using software Microsoft Excel 2020 and IBM SPSS Statistics 26. The research results show that the application of VBA media Excel through learning models problem-based learning can improve students' mathematical reasoning abilities and active learning. One of the findings shows that students have the ability and skills to apply concepts or material through problems that exist in the student environment and are able to complete complex calculations, analyze data, or prepare solution processes through VBA Excel.

This study aims to determine the effect of the discovery learning model in improving mathematical problem solving abilities and habit of minds of class VII middle school students. The research method used in this study is quasi experiment. This research was carried out in one of the private junior high school in the city of Cimahi by selecting two classses, namely VII A dan VII B. Each clas has 30 students. The instruments used were 5 questions on problem solving ability and habit of mind. Data in the form of test result and questionnaries were processed using the N-gain test and the difference test between two averages with the help of the SPSS. The result showed that the class whose learning used the discovey learning model had mathematical problem solving ablities and students’ habit of minds better than the class which used ordinary learning.

This research aims to determine and analyze students' mathematical reasoning abilities in terms of students' learning motivation (high, medium and low). The research method used is descriptive qualitative, namely a research method that will describe a phenomenon. The subjects in this research were 34 class VIII students at a school in Cimahi City. The instruments used were a mathematical reasoning ability test, a learning motivation questionnaire, and an interview guide. Data from the research results were processed based on student learning motivation in the high, medium and low categories for each indicator of mathematical reasoning ability. Based on the research results, it shows that the average value of mathematical reasoning ability of students with high learning motivation is 64.4%, the average value of mathematical reasoning ability of students with moderate learning motivation is 62%, and the average value of mathematical reasoning ability with motivation low learning by 50%. In general, among students' difficulties in working on mathematical reasoning ability questions are errors in mathematical calculations, this shows that students do not understand the concept and only use their memory to solve the problem.
