Abstract

Cognitive is the way students communicate their thinking processes in problem-solving. In solving problems, it is not only influenced by their thinking process, but other factors can affect it, such as gender differences. One of the subjects that can demonstrate students' cognitive abilities is the topic of circles. This study aims to determine students' cognitive abilities in solving circle problems from the perspective of masculine and feminine gender. The type of this research is exploratory research with a qualitative approach. This research was conducted in the 11th grade at SMA Negeri 1 Torue. The subjects in this study consist of one male student and one female student. After determining the research subjects, they were given a circular task. In addition, interviews were conducted while the subjects completed the task. The data analysis techniques used in this study are data condensation, data presentation, and conclusion drawing. The results of this study indicate that female students can solve circle problems by expressing all cognitive aspects in detail, neatly, clearly, and correctly. Meanwhile, when solving circle problems, male students express all cognitive aspects briefly and correctly.

Abstract

Understanding exponent material helps students understand more complex concepts, such as exponential functions, logarithms, and exponential growth or decay. However, many students still have difficulties learning that material. The problems experienced by students usually come from understanding the basic concepts and complex rules of exponents. This can affect the achievement of learning objectives and learning outcomes. One of the factors that can affect student learning outcomes is that the learning media provided by the teacher is less attractive to students. One of the factors that can influence student learning outcomes is that the learning media provided by teachers are less attractive to students. So this research aims to improve student learning outcomes by implementing an interactive Kahoot website on Exponent material. This research is classroom action research (PTK) which was carried out over two cycles. Each cycle includes stages of planning, action, observation, and reflection. The subjects in this research were 36 students in class X-2 at SMAN Model Terpadu Madani Palu in the odd semester of the 2024/2025 academic year. Data is collected through administering tests and observations. The data analysis techniques used in this research are quantitative and qualitative. Based on the results of data analysis, it was found that the average learning outcomes of students in the pre-cycle were 63, cycle I was 69, and cycle II was 73. This shows that there was an increase in mathematics learning outcomes, so it can be concluded that the application of the Kahoot website can improve the mathematics learning outcomes of class X-2 students at SMAN Model Terpadu Madani Palu

Abstract

This study aims to describe students’ mathematical communication skills in solving problems related to angle relationships, taking into account gender differences among students of SMP Negeri 1 Sindue Tobata. This research employed a qualitative approach with two eighth-grade students as subjects, consisting of one male and one female student, both identified as high-ability learners. Data were collected through tests and interviews. The results revealed that the male student demonstrated mathematical communication skills in understanding mathematical ideas both orally and in writing, using mathematical terms and notations, interpreting mathematical ideas through graphs and symbols, and evaluating ideas orally, although his written evaluations were still lacking. In contrast, the female student exhibited better skills in evaluating mathematical ideas both orally and in writing. These findings provide insights into the differences in mathematical communication skills between high-ability male and female students within the context of mathematics learning.

Abstract

The aim of this study is to analyze the types of errors and the contributing factors in solving final semester mathematics exam questions among Grade VIII junior high school (JHS) students. This is a descriptive study using a qualitative approach. Data on errors were collected from the Final Semester Examination (FSE) results and through in-depth interviews with 28 Grade VIII JHS students in Palu City during the 2022/2023 academic year. Based on the analysis of five tested topics, number patterns, Cartesian coordinates, relations and functions, linear equations, and systems of linear equations in two variables, it was found that the most frequent errors were conceptual errors, particularly in the topics of Cartesian coordinates and linear equations. The main factors contributing to these errors include students’ inability to determine and apply appropriate formulas, as well as limited competency in performing calculation operations.

Abstract

The purpose of this study was to describe the metacognition of grade IX students of SMP Negeri 19 Palu in solving numeracy problems based on reflective and impulsive cognitive styles. Metacognition in this study includes three aspects namely awareness, regulation, and evaluation observed at each stage of problem solving according to Polya's model. This descriptive qualitative research used Matching Familiar Figures Test (MFFT-2021), numeracy written test, think-aloud protocol, and in-depth interviews for data collection. In-depth study subjects consisted of two students, one each with reflective cognitive style and one with impulsive cognitive style. The results showed that at the stage of understanding the problem, reflective students showed high awareness and were able to organize their thoughts to understand the context of the problem in depth, while impulsive students tended to be faster in understanding the problem without in-depth analysis. At the stage of developing a plan, reflective students perform good regulation and evaluate the plan made, while impulsive students show awareness and regulation, but the evaluation of the plan is not always consistent. At the stage of implementing the plan, reflective students are able to evaluate the ongoing process, although this evaluation is more visible at the final stage, while impulsive students are less consistent in evaluation during the implementation of the plan, with evaluation only appearing at the final stage. Finally, at the looking back stage, reflective students showed a clear evaluation, although awareness and regulation were not significantly visible, while impulsive students only showed evaluation at the final stage without any deep reflection on the process that had been passed. Overall, reflective cognitive style tends to produce a more complete and in-depth metacognitive involvement in each stage of problem solving, while impulsive style shows a more limited and less consistent involvement in the evaluation aspect.      Keywords: metacognition, numeracy, cognitive style, reflective, impulsive.
