There are facts obtained through interviews and observations of students' answers that the VII grade students of SMP LKIA Pontianak are suspected of having misconceptions. Based on theses facts, the purpose of this research is to reveal the form of misconception based on Mason stages and the causes of the misconception. The subjects involved in this research were fifteen students. This research is a case study research with a descriptive method. Data collection tools used modified CRI diagnostic tests and interviews. Based on data analysis, the misconceptions experienced by students in completing set operations consisted of notation misconceptions, generalization and specialization. Researchers found out of the three forms of misconception, the most common is notation misconception. In the problem solving stage according to Mason consists of three stages, namely entry, attack, and review, students who experience misconceptions in two stages, namely at the entry stage, students experience notation misconceptions and at the review stage, students experience misconceptions of notation, generalization, and specialization. Researchers found the causes of misconceptions consisted of three factors, namely students' associative thinking, incomplete / wrong reasoning, and wrong intuition. Researchers found out of the three forms of misconception, the most common is wrong intuition. Keyword: Causes of Misconceptions, Mason Stages, Misconceptions

AbstractThe mathematical representation ability referred to in this study is the ability to express mathematical ideas or ideas to solve a problem with various mathematical representations of visual forms (pictures) and verbal forms (writing).This type of research is descriptive with a qualitative approach which aims to describe systematically the ability of visual mathematical representations and the ability of verbal mathematical representations.The data collection technique in this study was carried out using essay. Test questions were given to student an grade VIII A at SMP Negeri 1 Mandor, where there were three groups, namely the upper, middle, and lower group. Students who will be interviewed are selected based on the representation ability test scores where only two students will represent for each group.The results showed that the ability of visual mathematical representation when given verbal form questions to answer indicators using pictures was in the percentage of students' average score 66.67% and the ability of verbal mathematical representation if given visual questions, for the answer indicator using words is in the percentage of the student's average score of 33.33%. Students still have difficulty with verbal representation if given a visual form. Keywords: visual representation, verbal representation and trangle material

One of the most important mathematical skills for students to master is the ability to solve problems. Students' enthusiasm for learning is one factor that influences their ability to solve mathematical problems. This study aimed to determine how students' learning interests in linear programming material influenced their ability to solve mathematical problems. This study employs a qualitative approach with a descriptive format. Interviews, mathematical problem-solving aptitude tests, and interest-based questionnaires were the research instruments used. After that, all of the data were analyzed in three stages: data reduction, data presentation, and verification. 22 XI SMA Negeri 2 Nanga Pinoh students served as the study's participants. Nine students were chosen to be interviewed out of the 22 students. According to the findings, students in the high-interest categories were able to correctly solve problems using the stages of problem solving. Students with a moderate interest in solving problems are able to answer questions about solving problems and meet indicators, but they are still less systematic in their completion at several other stages. Students in the low-interest category can only finish when they understand the problem and have not been able to plan, implement, or reevaluate strategies

This study aimed to (1) determine the classification of students’ response in completing story questions based on the SOLO taxonomy; (2) discover the challenges of students in completing story questions on number patterns. The methodology used in this study was descriptive qualitative with a case study approach. The participants were 22 of 8th-grade students at SMP Sugiyopranoto Sanggau and the data sources were the results of story questions on number patterns and interview transcripts with the students. The result of this study indicates that response of high-achiever students reach the relational level of 8%, the students have already understand the number pattern materials quite well, take notes all the information contained on the questions, are able to correlate the separate information properly, write down the calculation steps and the conclusions given were also relevant. The response of moderate-achiever students reach the multistructural level of 40%, the students sufficiently understand the questions, take notes several important information and utilize it at the calculation, however, the correlation of separate information and concepts were not clear so that the calculation and the answers obtained were not reasonably right. Meanwhile, the response of low-achiever students are at the unistructural level of 21%, the students were still formula-oriented, and used merely one concept or one calculation step which caused the results obtained to be incorrect.

This research aims to describe students' adaptive reasoning abilities in solving contextual problems on absolute value topic based on adversity quotient (AQ) of climber, camper and quitter types at SMAN 1 Teluk Keramat. The method used in this research is descriptive. Based on the results of the research. This research subjects were six students at X MIPA 2 in the 2021/2022 academic year which three subjects have AQ of climber and three subjects have AQ of camper. Based on the results of data analysis, it was found that the adaptive reasoning abilities of students who have the AQ climber type have different abilities from each other, two of the three subjects of the AQ climber type are able to answer all indicators of adaptive reasoning, and the other one is only able to answer four reasoning indicators; the adaptive reasoning ability of students who have the AQ camper type also has different abilities from each other but three subjects from the AQ Camper type are able to fulfill three of five indicators of adaptive reasoning; the adaptive reasoning ability of students who have the AQ quitter type was not found in this research.
