This research is motivated by the existence of a driving school program, the lack of teaching materials used in schools, and the difficulties of students in solving cross product problems, as well as learning that is only centered on educators. So it is necessary to develop cross product teaching materials whose learning is centered on students. The teaching material developed in this research is a cross product teaching module based on problem based learning related to mathematical problem solving abilities. This study aims to determine the level of validity, effectiveness, and practicality of teaching modules. The research method used is Design-based-Research (DbR) with the plomp model. Sources of data in this study are validators of media experts, material experts, students, respondents of mathematics teachers. Based on the results of the analysis carried out, it can be concluded that the teaching module developed is valid, small group trials are effective and the response from educators is very practical. It is recommended that further research be carried out on a large scale, using different mathematical abilities and learning models.

This research is motivated by the regulation of the Ministry of Education and Culture of the Republic of Indonesia which has issued a driving school program. The needs in the driving school program are the existence of teaching devices in the form of teaching modules to realize the profile of Pancasila students. In learning activities, students' mathematical problem solving skills are still low, one of the learning models to improve problem solving skills is the Problem-Based Learning model and students are still having difficulty solving vector material in vector sub operations, so it is necessary to develop a Vector Operations Teaching Module Related to Mathematical Problem Solving Ability Problem-Based Learning. The purpose of this study was to determine the validity of the teaching module, the effectiveness and practicality of the developed teaching module. The research method used in this study, namely Design Based Research with the Plomp model. Sources of data in this study are validators of material experts, media experts, and respondents. The instruments used are material expert validation sheets, media experts, ability tests, affective questionnaires, affective observations, psychomotor observations and educator response questionnaires. The data were analyzed using percentages which were interpreted according to their qualifications. Based on the results of the analysis, it can be concluded that the teaching module developed is very valid, effective, and practical. It is recommended that further research be carried out for large-scale trials, different materials or other mathematical abilities.

This research is motivated by the lack of student motivation to learn, causing student learning outcomes to be low. Alternative media that can be used to increase students' motivation and learning outcomes is wordwall educational game media. The purpose of this study was to determine whether there was a significant effect of the use of wordwall educational games on the motivation and learning outcomes of seventh grade students in the quadrilateral material. This research is a quantitative research with an experimental model. The data collection technique for motivation is a questionnaire, while the data collection for learning outcomes is pretest and posttest. The data analysis technique was carried out using SPSS 19.0 for windows with t-test. The results of this study indicate that the use of wordwall educational games in mathematics learning activities has a significant effect on students' motivation and learning outcomes. It can be seen from the percentage of learning motivation in the experimental class is higher than the control class and the average value of the experimental class is higher than the control class.

The purpose of the study was to find out the description of the mathematical problem solving abilities of VIII-C class PENIDA Katapang Junior High School students in circle material. The research uses a qualitative approach with a descriptive method. Data collection techniques using documents, tests and in-depth interviews. The research subjects were six people consisting of students in the upper, middle and lower categories. The research subjects were determined by purposive sampling technique by using documents study. To find out the problem solving ability of students using test questions that have been validated. In-depth interviews were conducted to find out the low problem solving abilities of student and their causes. The results show that the problem-solving abilities of students were included in the weak category at each level, namely: (1) for the upper category, it was sufficient; (2) for the medium category including less; and (3) for the lower category including very less. So that the overall student problem solving ability is at a low level.

Polyhedron are a part of mathematics that are often considered difficult by students, so there are many mistakes made by students in solving problems of polyhedron. This is caused by the lack of students' mathematical understanding ability. Therefore, it is necessary to analyze the students' mistakes in solving mathematical understanding problems with the discussion of polyhedron. Based on this, this study aims to (1) determine the relationship between mathematical understanding and the student's mistake phenomenon (2) find out the forms of mistakes made by students in solving the problem of polyhedron. Participants in this study consisted of 7 students who were selected according to research needs. This study uses a qualitative approach and descriptive method with a case study design. The data obtained were analyzed using constant comparative techniques and qualitative coding. The results of this study indicate the forms of mistakes that arise from solving mathematical understanding ability test questions, namely (1) mistakes in identifying concepts (2) mistakes in absorbing information about questions (3) mistakes in using principles (4) mistakes in completion procedures (5) calculation mistakes on the process of determining the final answer.

The problem behind this research is the low mathematical analysis ability of learners in mathematics learning. One alternative learning that can be applied to improve learners mathematical analysis ability is the Group Investigation Model. The purpose of this study was to determine the improvement of mathematical analysis abilities of learners who learned using the Group Investigation Model and Discovery Learning Model. The research method used in this study is a quasi-experimental method. The population in this study were all VIII grade learners in one of junior high schools in Bandung district with a sample of learners in class VIII-H as an experimental class and class VIII-J as a control class. The instruments used is a mathematical analysis ability test. Based on the results of the Mann Whitney test analysis the mathematical analysis ability test obtained a conclusion that is improvement of mathematical analysis ability of learners who learn using Group Investigation Model better than learners who learn using Discovery Learning Model.
