Abstract

Tujuan dari penelitian ini untuk memperoleh deskripsi hasil analisis pemecahan masalah luas permukaan dan volume balok siswa kelas VIII SMPN 1 Palu berdasarkan tahapan Polya ditinjau dari kecerdasan visual spasial dan kecerdasan logis matematis. Subjek penelitian ini adalah satu siswa yang memiliki kecerdasan visual spasial dan satu siswa yang memiliki kecerdasan logis matematis. Hasil dari penelitian ini menunjukkan bahwa siswa yang memiliki kecerdasan visual spasial memiliki pemecahan masalah yang masih tergolong rendah. Pada tahap memahami masalah siswa mampu menentukan hal-hal apa saja yang diketahui dan hal-hal yang ditanyakan dengan tepat. Pada tahap menyusun rencana, siswa memiliki strategi pemecahan masalah yang kurang tepat. Tahap melaksanakan rencana, siswa melaksanakan rencana pemecahan masalah sesuai dengan rencana sebelumnya. Tahap memeriksa kembali, siswa melakukan penghitungan kembali terhadap jawaban yang telah diperoleh. Siswa yang memiliki kecerdasan logis matematis memiliki pemecahan masalah yang baik. Tahap memahami masalah siswa mampu menentukan hal-hal apa saja yang diketahui dan ditanyakan dengan tepat.

Abstract

The objectives of this study are: (1) To describe the analogical reasoning of class XI MAN 1 Poso students in the material of geometric sequences from field independent cognitive style and field dependent cognitive style. This type of research is descriptive research using a qualitative approach. The subjects in this study were two students of class XI MIPA MAN 1 Poso even semester 2021/2022 consisting of one RM student with FI cognitive style and one FN student with FD cognitive style. The students' cognitive style data was obtained by giving the GEFT test, while the students' analogy reasoning data were collected from the analogy reasoning test and interviews. The results of this study indicate that (1) field independent cognitive style students' RM fulfills all stages in each indicator of analogical reasoning and can explain the analogy used, namely in the source and target problems there are similarities or analogies in the solution, namely using the nth term formula. in the geometric sequence, namely  so it is included in high analogical reasoning. (2) While the field dependent cognitive style students' FN tend to be less able to fulfill all stages of each indicator of analogical reasoning. At the applying stage, FN has not been able to apply the relational structure of the source problem in solving the target problem, and tends not to be able to explain the analogy used. because it can't explain the analogy used so FN is included in moderate analogy reasoning.

Abstract

This study aims to describe the thought process of students in solving problems in terms of personality types guardian and idealist in class XI SMA Negeri 5 Palu. This research is a qualitative descriptive research. The main instrument in this research is the researcher himself and supporting instruments are The Keirsey Temperament Sorter (KTS), math the problems, and interviews. The results of this study show that guardian students and idealist students are able to perform all stages of the thinking process in solving math problems, namely receiving information, processing information, and forming conclusions. Guardian and idealist students at the stage of receiving information read the problem well. Guardian students read enough once to understand the problem, while idealist students read repeatedly to understand the problem. At the information processing stage, guardian students can explain the problem solving plan while idealist students have difficulty explaining the solution plan. At the conclusion formation stage, guardian students consistently solve the problem according to what was previously planned. idealist students at the conclusion formation stage can solve the problem even though at the information processing stage they cannot explain the solution plan.
