ANALISIS KEMAMPUAN SPASIAL SISWA DITINJAU DARI PERBEDAAN GENDER DALAM MENYELESAIKAN SOAL BANGUN RUANG KUBUS

Ahmad Ihsanudin Maulid — 2023-12-05

Matematika memiliki peranan penting dalam aspek kehidupan. Salah satu materi yang diajarkan adalah geometri. Geometri merupakan salah satu materi yang sulit diterima oleh siswa. Pada materi ini memerlukan kemampuan yang bernama kemampuan spasial. Kemampuan spasial memiliki beberapa inikator, indikator kemampuan spasial siswa terdiri dari; 1) pengimajinasian; 2) Pengonsepan; 3) Pemecahan masala; 4) Menentukan pola (Ummi :2015). Berdasarkan penguraian indikator tersebut, sangat memungkinkan seorang siswa memiliki tingkat kemampuan spasiual yang tinggi, cepat dalam memahami dan menyelesaikan soal matematika terutama geometri. Penelitian ini bertujuan untuk mengetahui sejauh mana kemampuan spasial siswa ditinjau dari perbedaan gender. Metode penelitian yang digunakan ialah deskritif kualitatif dengan subjek 3 siswa laki-laki dan 3 siswa perempuan kelas V SDN Muncul 03. Hasil dari penelitian ini ialah kemampuan spasial laki-laki sudah memenuhi indikator kemampuan spasial, sedangkan siswa perempuan hanya memenuhi beberapa indikator saja. Penelitian ini bisa menjadi acuan guru untuk meningkatkan kemampuan spasial siswa, karena guru sudah mengetahui suda sampai mana siswa mengerti materi yang disampaikan terutama pada geometri.

DIAGNOSIS KESULITAN BELAJAR MATEMATIKA PADA POKOK BAHASAN BILANGAN BULAT NEGATIF PADA SISWA KELAS V DI SDN 108 BANOA

Suci Triana — 2023-12-05

Difficulty in learning mathematics is an obstacle to problems in everyday life so it needs to be mastered well, but most students consider mathematics to be a difficult subject, especially fifth grade students at SDN 108 Banoa, the perception that mathematics is a difficult subject is reinforced by learning outcomes in mathematics which is still low. The purpose of this research is to identify difficulties in learning mathematics and the factors that cause difficulties in learning mathematics, especially for negative integers. Observations, interviews, and documentation are used as data collection methods in descriptive qualitative research. It uses triangulation to check the accuracy of the data and through the process of data collection, data presentation, and drawing conclusions, the data is analyzed. Based on the results of the study that students' learning difficulties in mathematics are still low, in this way the teacher must be more creative in choosing the learning method.

The objective of this study is to determine errors and causal factors in junior high school students in solving mathematical problems in comparative material. The descriptive qualitative method was used in this study. This study was conducted at SMP Muhammadiyah Kupang. Six students participated in this study, with two students having high abilities, two students having moderate abilities, and two students having low abilities. Written examinations centered on comparison material and interview results were used to collect data. The results of the tests and interviews were analyzed based on the indicators of the types of errors and the causal factors, namely: concept errors, principal errors and operational errors. The results showed that. (1) Student with high category abilities, made one mistake, namely an operation error, the subject was wrong in the process of calculating the final answer. (2) Students with moderate categories make mistakes, namely, prinsi errors, principle errors do not write comparison formulas when solving problems. (3) Students with low categories i.e. subjects commit misconceptions, i.e. subjects have difficulty in determining concepts from comparisons.
