Abstract

Perbedaan tipe kepribadian yang dimiliki setap orang dapat menyebabkan perbedaan dalam memecahkan suatu masalah. Tujuan dari penelitian ini ialah mencari perbedaan kemampuan pemecahan masalah antara siswa ekstrovert dan introvert berdasarkan langkah pemecahan masalah menurut Polya. Subjek dalam penelitian ini ialah siswa kelas X IPA-3 yang berjumlah 28 orang di salah satu SMA Negeri yang ada di Bojonegoro. Instrumen yang digunakan ialah angket tipe kepribadian dan tes pemecahan masalah materi SPLTV. Teknik analisis data secara kuantitatif digunakan untuk menunjukkan bahwa terdapat perbedaan kemampuan pemecahan masalah dilihat dari rata-rata hasil skor sedangkan untuk mengetahui perbedaan lebih jauh mengenai perbedaan tersebut maka dianalisa secara kualitatif. Hasil penelitian menunjukkan bahwa pada langkah memahami masalah 58% siswa ekstrovert kurang lengkap dalam menyebutkan informasi yang terdapat pada soal. Sementara , 88% siswa introvert menyebutkan keseluruhan informasi yang terdapat dalam soal, baik yang diketahui maupun yang ditanyakan. Pada langkah merencanakan pemecahan masalah 67% siswa ekstrovert hanya menuliskan satu metode saja yang akan mereka gunakan, yakni metode eliminasi. Sementara itu, 94% siswa introvert menuliskan kedua metode yang akan digunakan, yakni eliminasi dan substitusi. Pada langkah melaksanakan pemecahan masalah, 50% siswa ekstrovert tidak mampu menyelesaikan jawaban sampai akhir. Disisi lain, 81% siswa introvert mampu menyelesaikan masalah sampai akhir secara lengkap dan sistematis. Pada langkah memeriksa kembali, 42% siswa ekstrovert hanya memeriksa sebagian langkah yang telah dilakukan. Hal berbeda ditunjukkan oleh 75% siswa introvert yang teliti memeriksa langkah demi langkah yang telah dilalui dan menyocokkan kembali hasil jawaban dengan perintah dalam soal sehingga menghasilkan jawaban yang tepat. Kata Kunci: kemampuan pemecahan masalah, materi SPLTV, tipe kepribadian ekstrovert dan introvert.

Abstract

Mathematical problem solving is student process in solving mathematical problems based on the steps of understanding the problem, devising a plan, carrying out the plan and looking back. The problems can be in the form of contextual open-ended problems. Students’s mathematical problem solving can vary based on the level of student’s self-efficacy. The aim of this research is to describe the contextual open-ended mathematical problem solving in junior high school students with high self-efficacy and low self-efficacy. The type of this research uses descriptive qualitative which was carried out in one of junior high school in Surabaya city, year 2022/2023. Data collection techniques consist of questionnaires, tests and interviews. The chosen subject is one of high self-efficacy student and low self-efficacy student with equivalent mathematical abilities. Data analysis techniques consist of data condensation, data display and verifying based on Polya problem solving steps. The results show at the understanding the problem step, high self-efficacy students are better at determining the known and unknown than low self-efficacy students. Even so, both restate the problem in detail and explain the conditions of data adequacy clearly. At the devising a plan step, high self-efficacy student has initial experience, whereas low self-efficacy student hasn’t. High self-efficacy student devising and explains more plans than low self-efficacy student. At the step of carrying out the plan, both carry out and explain the steps according to the plan. However, high self-efficacy student use more strategies than low self-efficacy student. At the looking back step, high self-efficacy student crosscheck her solutions, stating her conclusions and mention examples of other problems that can be solved in a similar way. Meanwhile, low self-efficacy student just write and explain conclusions inappropriately.

Abstract

The activity of finding solutions to math problems is not easy. Most of the seventh grade junior high school students had difficulties in solving problems related to one variable linear inequalities material. Students experience difficulties in solving problems at the Polya problem solving stage. The difficulties experienced by students can be helped by providing scaffolding. This study aims to describe the process carried out by students in solving mathematical problems in the material of one-variable linear inequalities, and to describe the provision of scaffolding in solving mathematical problems in the material of one-variable linear inequalities. This study uses the selection of subjects by administering tests. Thus, it can be seen clearly the stages of solving the questions carried out by students. The research was conducted at SMP Negeri 25 Surabaya, which was attended by 32 students of class VII. The PtLSV problems given are two questions. A total of three research subjects were taken from the initial test, of the three subjects who experienced difficulties at all stages of solving the Polya problem, they would be interviewed and given scaffolding. The results showed that students experienced difficulties in the process of solving mathematical problems in the material of one variable linear inequality. This can be seen from the results of the students' work which did not write down any information that was known and asked about the questions, students could not devise a solution plan for the questions given. Students do not carry out the completion plan, and students do not re-check the answers that have been obtained. Providing scaffolding in this study, adjusted the location of the difficulties experienced by students in solving problems. Keywords: Problem Solving, Scaffolding, One Variable Linear Inequality
