The aim of this research is to understand junior high school students' mathematical critical thinking abilities when facing SPLDV problems. The approach applied is a qualitative approach in the descriptive method. Subjects were selected using a purposive sampling technique and then 3 students were selected from 31 students in class VIII-5 of SMP N 1 Tualang. The test instrument used consists of three questions. Then students' responses were categorized into high, medium and low categories and analyzed these responses using indicators of critical thinking skills in the context of mathematics. Research findings show that students in class VIII-5 at SMP N 1 Tualang have critical mathematical thinking skills and are categorized as sufficient. This can be seen in the answers to test questions which do not cover several aspects of mathematical critical thinking skills. Mathematical critical thinking abilities were measured in three categories, high (9.68%), medium category (70.98%), and low category (19.36%).

This study aims explicitly to look at differences in computational thinking and mathematical ability of students who received learning with augmented reality media based on gender. Background Problems: This research is motivated by students’ low mathematical Computational Thinking (CT) ability and the rapid development of information technology in the digital era. Augmented Reality is a technology that combines three-dimensional virtual objects into a natural environment and then projects these virtual objects in real-time. The research subjects were 30 class VII students of SMPN 34 Pekanbaru in the 2022/2023 school year, randomly selected. This research was conducted on flat geometric materials, especially triangles and quadrilaterals. The data collection methods used a test of mathematical computational thinking ability. Parametric statistical tests processed test results data. The results showed differences in computational thinking and mathematical ability of students who received learning using augmented reality media based on gender. Male students’ computational thinking and mathematical ability are better than female students.

This research aims to determine the mathematical creative thinking abilities of class VII students at SMPN 6 Siak Hulu. In this study, four indicators were used, namely fluency indicators, originality indicators, flexibility indicators, and elaboration indicators. In the learning carried out, especially in mathematics learning, students must have the ability to think creatively and mathematically. The ability to think creatively mathematically is the ability to think to find new ideas or thoughts in general or original with the aim of providing definite and precise results. The subjects in this research were 28 class VII students using qualitative descriptive methods. The instrument in this research used four essay questions and interviews on mathematical creative thinking abilities. The results of research on students' mathematical creative thinking abilities at SMPN 6 Siak Hulu obtained meager results. The average percentage for all indicators is 18%.

This research is motivated by the large number of students who make mistakes when working on questions, so it can be an indication of how well students understand the material. SPLTV material was chosen for this research because SPLTV has components that students must understand so that they can easily determine mistakes made by students. This research aims to reveal the facts, circumstances, phenomena, variables and circumstances that occurred when the research was conducted. This type of research is qualitative research with a quantitative descriptive approach. The research subjects were 34 class X students at SMAN 2 Tualang. The data collection techniques used in this research are: 1) written tests, and 2) interviews. Based on the results of data analysis, a conclusion was obtained which showed that students made mistakes in Newman's stages, namely: errors in reading were 23.53%, which means that the majority of students read the question instructions well. The large percentage of students making errors in understanding is 91.18%, and students making transformation errors with a percentage of 55.88%. In process skill errors, the number of students who made mistakes was 82.35%, and 88.23% of students made mistakes in writing/notation. Factors that cause errors include: not being careful, not being able to read the question, not understanding the problem, and not being able to carry out the procedures or steps that will be used to solve the question.

Interest in learning is a source of intrinsic motivation that encourages students to do what they want so that it has an impact on student achievement. The purpose of this study is to obtain information about the interests in learning mathematics for MTs students while learning using Augmented Reality media. Quantitative descriptive method is used in this research. Respondents in this study amounted to 20 students at MTs. Data was collected from a student interest questionnaire with 18 statement items which were analyzed using the Rasch model. The results showed that the quality of the statements in the questionnaire was included in the sufficient category, and the level of consistency of students' answers was also in the sufficient category. Cronbach's alpha value is in the very good category, namely 0.85 which can be used to assess the reliability of the interaction between Person and the item as a whole. Furthermore, the level of student interest in MTs in Kampar using Augmented Reality learning media is in the high category. The logit value is 1.62, meaning that the statement items are mostly approved by students

This research is motivated by the low ability of students to solve mathematical problems, which is reflected in the results of surveys and previous research. Even though mathematics is considered an important subject, many students still experience difficulties in understanding and solving mathematical problems, including solving problems with systems of linear equations in one variable. The research method used is descriptive with a quantitative approach. This research aims to describe and analyze students' problem solving abilities. The subjects used were 30 selected class VIII students at Al-Faruqi Middle School. Data was collected through tests, then analyzed to identify student errors in solving problems on systems of linear equations in one variable. The results of the research show that the majority of students experience difficulty in understanding basic concepts, are less thorough in the problem solving process, have difficulty understanding problem questions, and have difficulty allocating time when working on questions. Based on data analysis, the percentage of student errors is classified as moderate. From these results, it is concluded that further efforts are still needed to improve students' mathematical problem solving abilities, especially in the context of one-variable linear equation systems. This can be done by focusing more on identifying factors that cause student errors and developing learning strategies that are more effective in improving students' understanding and problem solving skills in mathematics.
