Abstract

ABSTRAK Tujuan penelitian ini adalah untuk memperoleh deskripsi kesalahan yang dilakukan siswa XI IPA SMA Negeri 3 Poso dalam menyelesaikan soal ujian akhir semester matematika berdasarkan metode Newman. Kelas XI IPA SMA Negeri 3 Poso banyak melakukan kesalahan dalam menyelesaikan soal Ujian Akhir Semester. Subjek penelitian ini sebanyak 3 siswa dari 33 siswa kelas XI IPA 1. Peneliti melakukan penelitian deskriptif dengan melakukan pendekatan kualitatif. Hasil penelitian ini menunjukkan bahwa: 1) Jenis kesalahan pada materi barisan dan deret ialah kesalahan memahami masalah, kesalahan transformasi, kesalahan kemampuan proses, dan kesalahan penulisan jawaban akhir, 2) Jenis kesalahan pada materi limit ialah kesalahan kemampuan proses yang terjadi dan kesalahan penulisan jawaban akhir, dan 3) Jenis kesalahan pada materi turunan ialah kesalahan memahami masalah, kesalahan transformasi, kesalahan keterampilan proses, dan kesalahan penulisan jawaban akhir.   ABSTRACT This research aims to describe the errors made by 11th-grade science students at SMA Negeri 3 Poso in solving final semester mathematics exam questions based on Newman's method. The 11th-grade science students at SMA Negeri 3 Poso made numerous errors in solving the final semester exam questions. The research subjects comprised 3 out of 33 students from class XI IPA 1. The researcher conducted a descriptive study using a qualitative approach. The results of this study show that: 1) the types of errors in the sequences and series material include errors in understanding the problem, transformation errors, processing skill errors, and errors in writing the final answer, 2) the types of errors in the limits material include processing skill errors and errors in writing the final answer, and 3) the types of errors in the derivatives material include errors in understanding the problem, transformation errors, processing skill errors, and errors in writing the final answer.

Abstract

Understanding students' cognitive processes in solving mathematical problems is crucial for improving instructional strategies and learning outcomes. However, limited studies have examined students' commognitive aspects in the context of geometric problem-solving, particularly in relation to cognitive styles such as Field-Independent (FI) and Field-Dependent (FD) tendencies. This study addresses this gap by analyzing the four aspects of commognition word use, visual mediators, narratives, and routines demonstrated by students when solving story problems on the surface area of a square pyramid. The study also explores the patterns of thinking and solution strategies employed by FI and FD students in approaching these problems. Conducted in Class VIII A at SMP Negeri 1 Sigi, the study involved two male students, one representing each cognitive style, to highlight differences in problem-solving approaches while controlling for gender. Data collection involved the Group Embedded Figures Test (GEFT) to determine cognitive style, validated problem-solving task sheets, and semi-structured interviews conducted in parallel with the written tasks. Data were analyzed using data condensation, data display, and conclusion drawing techniques. The findings indicate that FI students approach problem-solving with greater detail, clarity, efficiency, and accuracy, explicitly demonstrating all four aspects of commognition. In contrast, FD students exhibit clarity, efficiency, and accuracy but lack detail and thoroughness in their written responses. Both cognitive styles demonstrate all four commognitive aspects, with notable differences in the narrative component FI students explicitly write formulas, whereas FD students understand the formulas but do not record them in writing. These findings provide valuable insights into how cognitive styles influence mathematical problem-solving and commognitive development, offering implications for differentiated instructional strategies in mathematics education.

Abstract

This study's objective is to determine the level of students' mathematical literacy skills before and after using the My Trip Math Adventure game. This research method uses a quantitative approach and employs a quasi-experimental design with a one-group pretest-posttest design. The sample of this study was grade V students of elementary school Inpres 15 Wara. The analysis technique used was descriptive statistical analysis and inferential statistical analysis. The results of the study indicated that there was an increase in students' mathematical literacy skills after the implementation of the My Trip Math Adventure game. The present study is based on the results of data analysis using descriptive statistics for students' mathematical literacy skills before the implementation of the My Trip Math Adventure game. Following the implementation of the My Trip Math Adventure game, 33% of students rated their mathematical literacy skills as high, while 67% rated them as very high. The results of the inferential statistical analysis (paired sample T-test) obtained a significance value of <0.05, which means that there was an increase in students' mathematical literacy skills after the implementation of the My Trip Math Adventure game in elementary school.
