The following research relates to the use of problem based learning (PBL) models in mathematics learning aimed at increasing student learning motivation. The subjects in this study were students of class XI in one of state vocational schools in Cimahi. Questionnaires and observation sheets as instruments used in this study. Research is carried out a number of two cycles, each cycle for one study, each cycle there are four main activities, namely planning, implementation, observation and reflection. The data collection technique in this study used questionnaires and observation sheets. The data analysis technique is descriptive qualitative, so that research results are obtained that show that there is an increase in student learning motivation in each cycle.This can be seen from the increase in students' positive motivation obtained from the questionnaire given. Because learning with a problem based learning (PBL) model has characteristics that are able to make students easily understand the material conveyed and motivate students to learn mathematics for the better.

The purpose of this research is to find out students' mistakes in solving algebraic operations according to Kastolan's theory. In this study used a qualitative descriptive method with the research subject of class VII in one of the MTs in West Bandung Regency with a total of 20 students consisting of 9 girls and 11 boys. The data collection technique was carried out in the form of a written test consisting of 5 description questionsFrom the results of the analysis of student errors based on Kastolan theory, there are several types of Kastolan errors overall, namely: 1) the type of conceptual error is 60%, this type of error is included in the high category 2) the type of procedural error is 40%sufficient category and 3) the type of technical error by 30% this type of error is included in the low category. Based on the results of the analysis that has been obtained from students' answers, the cause of the errors that exist in each of these errors is an error in making mathematical models, students do not show completion strategies and students' lack of ability to perform arithmetic operations.

Learning abilities that are elements of learning in the 21st century require teachers to have skills in guiding students to develop communication skills, process information, think creatively, solve problems, collaboration and manage themselves. These abilities can be developed through the implementation of innovative learning in the classroom, one of which is the STEM approach. STEM-based learning integrates four fields, namely science, technology, engineering and mathematics in one learning activity. This service activity was carried out by 30 mathematics teachers who were members of the Mathematics teacher community in Denpasar City. The activity is carried out using the Asset Based Community Development (ABCD) method. The service activities that have been carried out have a good impact on teachers. At the end of the activity, teachers can understand STEM-based mathematics learning through practical learning activities and are able to develop learning innovations by compiling STEM-based learning scenarios.

This research is a class action research (CAR). The aim of the study was to find out, [1] the application of problem-based learning to improve the mathematical reasoning abilities of SMK students [2] the effect of problem-based learning to improve the mathematical reasoning abilities of SMK students. The research was carried out using a qualitative descriptive method and adapted to indicators of mathematical reasoning based on Kemmis and Mc Taggart's analysis. research subjects were 36 students of class XI Multimedia 2 at SMKN 3 Cimahi 2021/2022. Collecting data in this study used observation, tests, self-confidence questionnaires and interviews. From the results of tests and interviews it is known that the basic concept of students' mathematical logic questions initially had errors in solving the problems, but there was an increase in each cycle. The results of data on mathematical reasoning ability affect the average percentage of the self-confidence questionnaire which tends to be high, namely score 4 of 25%, score 3 of 19.4%, score 2 of 31.7% and score 1 of 7.9%, so the conclusion is that the mathematical reasoning abilities of SMK students belong to the medium category.

This study aims to determine the characteristics of the problem solving abilities of class VIII students in a junior high school in West Bandung Regency. In this study using a qualitative descriptive research method. Data collection techniques in this study were in the form of problem-solving skills tests and interviews. The results of the tests and interviews were analyzed for each item based on Polya's ability to solve problems. The test instruments used were test descriptions of problem solving questions and interview guidelines. Based on data analysis that refers to indicators of problem solving ability, the research results obtained that the indicator of solving problems obtained results of 87%, and on the other 3 indicators namely understanding the problem obtained results of 55%, planning problem solving obtained results of 30% and buying back problems obtained results of 20%. Thus, there were still a number of errors found in the results of student answers in solving problem-solving solutions including: not listing what was known, asked, and not describing these elements, the process of planning problem solving was not systematic, did not understand problems, errors in calculating answers, and not writing conclusions from the results of the settlement. Students are not used to solving problems in the form of stories with complex daily life contexts, which is a factor that is often found in junior high school students.
