This research aims to determine the misconceptions of class VII B students at SMPN 12 Jember using a qualitative descriptive. Instrument method used by researchers in the form of written test questions on algebra material consisting of three items with the Three Tier Test method which has three levels of difficulty, namely low, medium and high. The Three Tier Test method questions have three levels of questions, namely questions for understanding students' concepts, questions about the reasons for students' answers, and finally questions about students' confidence in answering these questions. From the research that has been carried out, several misconceptions have emerged, namely, the misconception of solving algebra is 61.2% of the total number of questions, the misconception of algebraic operations is 58.1% of the total number of questions, and the misconception of sign errors is 87.1% of the total number of questions.

The purpose of this study was to determine whether the understanding of mathematical concepts in class VIII students of SMP Negeri 1 Tinambung who were taught using the STEM learning model was higher than the understanding of mathematical concepts in class VIII students of SMP Negeri 1 Tinambung who were taught using the direct learning model. This type of research is a quasi-experimental with a nonequivalent control group design which was carried out at SMP Negeri 1 Tinambung for the 2022/2023 academic year. The sampling technique used was cluster random sampling with class VIII A as the experimental class and class VIII B as the control class. Data collection techniques include tests, observations and questionnaires. While the data analysis techniques used descriptive analysis and inferential analysis. Based on the results of descriptive analysis it can be concluded that students' understanding of mathematical concepts taught using the STEM learning model is included in the good category, students' understanding of mathematical concepts taught using the direct learning model is included in the sufficient category. Then, the result of inferential analysis, show that students' understanding of mathematical concepts taught using the STEM learning model higher than the understanding of students' mathematical concepts taught using direct learning models.

The ability of students in Indonesia in terms of critical thinking is not yet high enough. Possible solutions include giving open ended questions to students. This research aims to determine whether students with various mathematical logical intelligences can use critical thinking to solve problems. The research methodology applied is descriptive qualitative. A total of 6 students were used as study subjects who were class VII-B students at SMPN 2 Sukodadi. As a tool, a logical-mathematical intelligence questionnaire was provided which was followed by a test to see the ability to solve problems. The resulting data is in the form of test results and interview results. The research results identified that: (1) Subjects who have high mathematical logical intelligence can go through 4 stages of critical thinking, including interpretation, analysis, evaluation and inference, and are classified as TKBK 4 (very critical); (2) Subjects who have moderate mathematical logical intelligence can go through 3 stages of critical thinking including interpretation, analysis and evaluation, and are classified as TKBK 3 (critical); (3) Subjects who have low mathematical logical intelligence can only go through 1 stage of critical thinking, namely interpretation, and are classified as TKBK 1 (less critical).

The aim of this research is to describe student errors in geometry using Ennis criteria. This research uses a qualitative approach and descriptive research type. Research instruments include tests, interviews. This research took 3 subjects with different abilities, namely students with high abilities, students with medium abilities and students with low abilities. Based on the research results, it was concluded that students' mistakes in solving problems based on Ennis' criteria were that students with high abilities made mistakes in the overview section. And students with moderate abilities make mistakes in the criteria of focus, inference, situation, clarity and overview. Wherease, students with low mathematical skills make mistakes in the criteria of focus, reason, situation, clarity and overview.

The development of technology in the world of education uses media in mathematics learning, teachers strive to make learning media and teaching materials for the smooth effective learning process. In the learning process, an IT-based learning media is needed that can attract the attention of students during the learning process, especially in the material Composition Function and Inverse Function. This study aims to develop android-based learning media using MIT App Inventor on valid and practical material for Composition Function and Inverse Function class X IIS SMA PGRI 3 Padang. This research uses R&D (Research and Development) research using Plomp development which consists of three stages, namely preliminary phase, prototyping phase and assessment phase. This research was only carried out until the prototyping phase stage. The results of the validity test showed that android-based learning media using MIT App Inventor on the material Composition Function and Inverse Function obtained a percentage of 91.64% with very valid criteria, the results of the practicality test with class X IIS SMA PGRI 3 Padang obtained a percentage of 85.64% with very practical criteria.
