Abstract

Based on the results of observations conducted by researchers on students of class IX SMP Negeri 14 Palu, namely working on practice questions related to exponents and there were several problems found, namely 1). Not all students understand the material on exponents 2). there are errors in solving the questions, namely in the exponent section. 3). some students can solve the questions until the middle, and 4). no students are able to finish. This study aims to analyze the errors of class IX students of SMP Negeri 14 Palu in solving exponent number problems. This type of research is descriptive research. The approach used in this study is a qualitative approach. The sample in this study was class IX Kihajar students of SMP Negeri 14 Palu consisting of 37 students, then given a test consisting of 5 questions on exponent number material and then 1 male and female student were selected who made the most mistakes. The results of this study indicate that the errors made by male students in solving exponent number problems are: (1) conceptual errors, namely students' errors in interpreting exponents. (2) principle error, students do not follow the steps that should be written in solving the problem. (3) Arithmetic operation error, students write the wrong answer from the multiplication result. (4) Fact error, namely students make mistakes in using operation symbols. The results of this study indicate that the mistakes made by female students in solving exponent number problems are: (1) Concept error, namely students' mistakes in interpreting the concept of exponents. (2) principle error, students do not write complete steps when solving the problem. (3) Arithmetic operation error, students make mistakes when subtracting, so that it has an impact on the final result. (4) Fact error, namely students make mistakes in using number operation symbols.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan komunikasi matematis siswa kelas VII SMP Negeri 2 Palu pada materi himpunan ditinjau dari Adversity Quotient (AQ). Menggunakan pendekatan deskriptif kualitatif, penelitian ini melibatkan tiga subjek siswa yang dipilih berdasarkan hasil kuesioner Adversity Response Profile (ARP) untuk mewakili tipe Quitter, Camper, dan Climber. Teknik pengumpulan data dilakukan melalui kuesioner ARP, tes tertulis, dan wawancara, yang kemudian dianalisis menggunakan teknik kondensasi data, penyajian data, serta penarikan kesimpulan. Hasil penelitian menunjukkan bahwa: (1) siswa tipe Quitter mampu mengidentifikasi informasi yang diketahui dan ditanyakan namun belum menggunakan simbol matematika dalam bentuk representasi; (2) siswa tipe Camper mampu menuliskan informasi yang diketahui dan ditanyakan menggunakan simbol matematika meskipun belum lengkap, serta mampu menggambar dan menjelaskan diagram Venn secara tepat untuk mendeskripsikan ide dan hubungan matematis secara lisan; (3) siswa tipe Climber menunjukkan kemampuan komunikasi matematis terbaik, meliputi keakuratan penulisan informasi menggunakan simbol matematika secara lengkap, ketepatan menggambar diagram Venn, serta pemahaman dalam mengekspresikan ide matematis baik secara lisan maupun tulisan. Temuan ini mengindikasikan bahwa tingkat Adversity Quotient memengaruhi variasi kemampuan komunikasi matematis siswa dalam menyelesaikan masalah pada materi himpunan.

Abstract

This study aims to obtain a description of the Concept Understanding of Students in class IX SMP Negeri 1 Sigi on circle material in terms of math ability. This type of research is qualitative research with descriptive approach. The subjects of this study are three students of class IX SMP Negeri 1 Sigi in the odd semester 2024/2025 consisting of 1 student with high mathematics ability, 1 student with moderate mathematics ability, and 1 student with low mathematics ability. Subjects are selected based on report card scores and subject teacher recommendations. Data were obtained from the results of written tests and interviews with research subjects. The data credibility was tested through membercheck. The results of the study indicate that, (1) Subjects with high mathematical ability (ST) meet 3 indicators of concept understanding, namely restating the concepts that have been learned, identifying examples and non-examples of concepts that have been learned, and applying concepts or algorithms to solve a problem. (2) Subjects with moderate mathematical ability (SS) meet 3 indicators of concept comprehension, namely restating concepts that have been learned, identifying examples and non-examples of concepts that have been learned, and applying concepts or algorithms to solve a problem. (3) Subjects with low mathematical ability (SR) only meet 1 indicator of concept understanding, namely identifying examples and not examples of the concepts that have been studied.
