Abstract

This study aims to describe the critical thinking profile of SMAN 5 Model Palu grade XI students in solving trigonometric identity proof problems regarding gender differences. The subjects in this study were male students or S1 and female students or S2 of grade XI Mipa 4 SMAN 5 Model Palu who have high mathematical abilities. Data were collected through tests and interviews. The results of this study indicate that S1 and S2 in solving trigonometric identity proofs have the correct answers and are accompanied by supporting reasons. However, there are some differences in thinking activities between the two, namely S1 who is a male student with high ability has a shorter answer than the solution of S2 who is a female student with high ability, S1 uses a logical way of thinking compared to S2 who tends to be proficient with his verbal abilities. This shows that S1 and S2 even though they have equal mathematical abilities, there are some differences between the two in solving trigonometric identity proofs whose data are obtained from written assignment answers and interview results.

Abstract

This research examines students' mistakes in solving mathematics story problems, especially algebraic arithmetic operation story problems, based on Kastolan theory and examines what factors cause students to make these mistakes. The type of research used in this research is descriptive qualitative. The place where the research was carried out was SMP Negeri 6 Palu. The subjects taken in this research were class VII students at SMP Negeri 6 Palu, consisting of 1 student with several considerations obtained as students with low MH abilities. Before analyzing the data obtained, it is validated first using member check. The data analysis techniques used in this research are data reduction, data presentation and drawing conclusions. The results of this research show that subject MH made 3 types of errors based on Kastolan's theory, namely: Conceptual Errors in the form of the subject not being able to apply the formula, classifying the form of variables in solving the problem when using the formula that has been obtained, the subject not writing completely the information known in the problem and errors in substituting known information into the question. Procedural errors in the form of irregularity in the solution steps used by the subject, there are several steps that are skipped so that the solution becomes wrong until the final stage of solving the problem. Technical error in the form of Subject MH making an error in calculating the value in the arithmetic operation shown in the subject only dividing by 2 each solution to get the result of the question in the problem because the subject did not understand the formula to be used and was not correct in substituting the value in the problem into problem solving. The factors that cause errors made by students are divided into two, namely internal and external factors. Internal factors include low basic knowledge regarding the form of arithmetic operations, solving steps for story questions and low knowledge of algebraic material. Lack of practice working on questions in the form of story problems and students' lack of accuracy in solving story problems. The external factor is that students are in a hurry when completing story problems because they want to finish them immediately and go to do other activities with their friends.

Hasil penelitian ini menunjukkan bahwa jenis-jenis kesalahan yang dilakukan siswa dilihat dari objek matematikanya yaitu kesalahan konsep, kesalahan fakta, kesalahan prinsip dan kesalahan prosedural. Kesalahan konsep yang dilakukan siswa yaitu (1) kesalahan dalam memahami konsep operasi hitung bilangan pecahan baik itu penjumlahan, pengurangan, pembagian dan perkalian. (2) kesalahan dalam memahami bentuk pecahan. Kesalahan fakta yang dilakukan siswa yaitu kesalahan mengubah tanda operasi pengurangan menjadi perkalian. Kesalahan prinsip yang dilakukan siswa yaitu kesalahan melakukan sifat komutatif pada pengurangan bilangan bulat. Dan kesalahan prosedural yang dilakukan siswa yaitu (1) kesalahan operasi hitung. (2) kesalahan prosedur tidak lengkap dan (3) kesalalahan mengerjakan sembarang. Faktor-faktor yang menyebabkan siswa melakukan kesalahan-kesalahan dalam menyelesaikan soal operasi hitung bilangan pecahan yaitu siswa tidak memahami konsep bilangan pecahan, siswa tidak memahami konsep operasi hitung bilangan bulat serta bilangan pecahan dan siswa tidak memahami sifat dari operasi hitung. Siswa malas untuk belajar walaupun sudah diminta belajar oleh orang tuanya, siswa cepat lupa dengan materi yang diberikan, siswa tidak tau cara menyederhanakan pecahan dan guru hanya memberikan pembelajaran dengan metode ceramah.

Abstract

The purpose of this research was to obtain a description of the mathematical representation of class VIIJ students of SMP Negeri 9 Palu in solving line and angle problems. This type of research is descriptive-qualitative. The research subjects consisted of 3 students, namely 1 student representing low ability, 1 student representing moderate ability, and 1 student representing high ability, based on the grades of even semester report cards for the 2021/2022 academic year. Collecting data using tests and interviews. In analyzing data, researchers used data reduction, data display, and conclusion drawing/verification. The results showed that subjects with low abilities had mathematical representation abilities in solving line and angle problems in problem number 1 but in solving problem number 2 they were still not good. This means that the subject meets the indicators of mathematical representation abilities which include image representation, verbal representation, and symbolic representation which are still not good. Subjects with moderate abilities have mathematical representation abilities in solving line and angle problems in question number 1 but in solving problem number 2 they do not show image representations. This means that the subject meets the indicators of mathematical representation which includes image representation, verbal representation, and symbolic representation quite well. Subjects with high ability have mathematical representation abilities in solving line and angle problems in questions number 1 and 2. This means that the subject fulfills all indicators of mathematical representation ability which include image representation, verbal representation, and symbolic representation well.

Abstract

This study aims to obtain a description of the surface area and volume problem solving profiles of class IX B students at SMP Negeri 1 Lore Tengah. This study uses a qualitative method with a qualitative descriptive approach. The research subjects were 3 students, namely students who had high, medium and low mathematical abilities based on the problem solving steps proposed by Polya. The research results obtained show that: (1) Students who have high mathematical abilities use all stages of Polya in solving problems of surface area and volume of cylinders. (2) Students who have moderate mathematical abilities have not been able to use all of Polya's stages in solving the problem of surface area and volume of cylinders, the stage in question is found in the re-examining stage. However, the subject gave his opinion by explaining using his own language why not re- examine the results of solving the problem given. (3) Students who have low mathematical abilities have not been able to go through all the stages of Polya in solving problems, the subject is only able to go through the stages of understanding the problem but the subject needs to read repeatedly and pay attention to the information contained in the problem repeatedly.
