PROFIL PEMECAHAN MASALAH BENTUK CERITA PADA MATERI PECAHAN SISWA KELAS VII SMP NEGERI MODEL TERPADU MADANI PALU: The Problem of Solving Story Problems on fraction Material In Grade VII Stundents At SMA Negeri Model Terpadu Madani Palu
Full text linkThis study aims to describe the problem solving of fractional. This type of research is descriptive using a qualitative approach. The subjects of this study were grade VII students of SMP Negeri Model Terpadu Madani Palu consisting of 3 students who were divided into 1 student with high mathematical abilities, 1 student with moderate mathematics ability, and 1 student with low mathematical abilities selected based on processing the final semester exam scores in odd semester 2021/2022. The results showed that students whit high math skills were able to solve problems well based on Polya’s problem solving steps, starting from the stage of understanding the problem, to the stage of re-examining the answers. Students who are mathematically capable are doing mathematical problem solving well at the stage of understanding the problem, the stage of making plans, but at the stage of implementing the plan students are wrong in changing the fraction division operation into the form of fraction multiplication operations, moderately capable subjects do not change the position of the numerator into the denominator and the denominator into the numerator which is the settlement area, the stage of re-checking the students answers only checks again by looking at the results of the answers. Students whit low math abilities have not done problem solving well, that is, they can only rewrite existing information without understanding the existing information, unable to make plans because they feel confused in thinking about plans that must be used to solve problems, cannot carry out problem solving plans. And can’t recheck the answer. This is because students cannot solve the given problem

Full text linkThis study is research that uses a qualitative a approach that aims to describe misconceptions of the Madrasah Tsanawiyah Kaleolangi Bou on integer arithmetic operations. The subjects in this study were two students class seven students of Madrasah Tsanawiyah Kaleolangi Bou who experience this type of misconception concept error. Data collection is done through written assignments, interviews and members check. The results of this study indicate that students' misconceptions (concept error) (1) students have not been able to understand correctly the rules summation operations, (2) students give a statement that if faced with the addition of addition operations students still add it without look at the negative, (3) students have not been able to understand the concept of operations subtraction properly, (4) students give a statement that students will gives a negative sign if he gets one of the two numbers operated is negative, and (5) students give a statement that if subtraction must be subtracted, students subtract numbers without see the positives and negatives that result in the results of the work experiencing errors
ANALISIS KEMAMPUAN SISWA DALAM MENYELESAIKAN SOAL POLA BILANGAN TIPE HOTS (HIGHER ORDER THINKING SKILL) BERDASARKAN KEMAMPUAN MATEMATIKA KELAS VIII B SMP IT (ISLAM TERPADU) QURRATA A’YUN PALU
Full text linkThis study aims to obtain a description of students' abilities in solving HOTS (Higher Order Thinking Skill) Type Number Pattern Problems Based on the Mathematics Ability of Class VIII B SMP IT (Integrated Islam) Qurrata A'yun Palu. This research is descriptive with a qualitative approach based on the problem-solving steps put forward by Polya. The results showed that subjects with high-level thinking skills and moderate-level thinking skills in solving mathematical problems with number patterns were as follows: (1) in understanding the problem, students with high-order thinking skills and moderate-level thinking skills demonstrated an understanding that was relevant to gathering information. The information contained in the problem can identify the problem of the problem with knowledge of the sentence "statement". (2) in planning problem solving, high-level ability subjects can plan a good strategy to achieve the goals in a problem and can choose relevant information from the problem. Meanwhile, subjects with moderate ability are quite good at planning problem solving however
formulating a strategy is still not appropriate to be able to solve the problem properly. (3) in carrying out a problem-solving plan, subjects with high levels of ability are very good at executing, and carrying out planning and are able to organize and integrate problems with relevant prior knowledge, as well as subjects with moderate levels of ability (4) in re-examining, high subjects re-examining because it can monitor, check or detect the final results and unexpected events. Meanwhile, subjects with moderate ability did not re-examine because they felt unsure about solving the problems they were doing.
