Abstract

This research aims to obtain a profile of students' Mathematical Communication Skills in derivative problems. Based on the Masculine Gender Group. The research uses a descriptive qualitative approach. The subjects in the research were three people from class XI students at SMA Negeri 1 Sigi. Subject selection is based on masculine gender. Data collection techniques include written tests, interviews and discussions. The research method uses within-method triangulation. The research results showed that (1) students with masculine gender stated the information in the questions using their own language, repeated their friends' explanations, wrote down ideas for solving derivative questions and wrote down the reasons for each step in solving the questions. clear (2) students with masculine gender can read the symbols contained in the derivative questions, write limit notation, explain the meaning of the graph in the picture. This subject can also repeat the explanation of the theme. Furthermore, (3) students with masculine gender can make conclusions from solving questions.

Abstract

The aim of the research is to summarize the experiences of grade 11 students at SMA Negeri 4 Palu based on Newman's theory. This type of research is descriptive, using a qualitative approach. The research subjects were two students selected from 35 class XI students. The findings of this research are as follows: (1) Not a single subject experienced errors in reading the lesson material, because at that time every subject was considered able to read the lesson material correctly. (2) Not a single subject made a mistake in understanding, as seen in the interview phase. All research subjects were able to provide understandable and questionable information regarding the subject. (3) Each research subject carries out transformation error correction. This transformation error is characterized by the failure of a subset that reduces the problem of the mathematical model. (4) Process skills errors were made by each research subject. This is explained by the subject's understanding of the steps taken in answering the question, but most of it is caused by the subject's errors occurring in the transformation step and the subject being unable to solve mathematical problems accurately. (5) an error in writing the final answer (encoding error) was made by each research subject; This is differentiated by the fact that there are subjects who do not determine the final results of their learning and there are also subjects who fail to determine the final results due to errors in the previous stage.

Abstract

This research was conducted to obtain descriptions of students in solving systems of two-variable linear equations (SPLDV) based on APOS theory in terms of mathematical ability. This type of research is descriptive with a qualitative approach. The subjects in this research were 3 students in class VIII B of SMPN 20 Palu in the odd semester 2023/2024 consisting of 1 student with high mathematics ability, 1 student with moderate mathematics ability, and 1 student with low mathematics ability. Data in the research were collected through written tests and interviews with subjects. The research results show that: (1) Students with high mathematical abilities can solve SPLDV questions by achieving all stages of APOS theory (action, process, object, and scheme); (2) Students with moderate mathematical abilities can solve SPLDV questions but have not been able to reach all stages of APOS theory, students with moderate mathematical abilities are only able to reach the APO stage (action, process and object); (3) Students with low mathematical abilities have not been able to solve SPLDV questions and are only able to reach the action stage at the APOS theory stage.

Abstract

Exponential functions pose conceptual challenges for secondary students due to their abstract nature. This quasi-experimental study investigated the effect of GeoGebra-based instruction on Grade 10 students’ conceptual understanding in two Indonesian senior high schools (N = 132). A validated four-item essay test (r > 0.219; Cronbach’s Alpha = 0.71) was administered before and after instruction. Mann–Whitney U analysis showed a significant difference in posttest conceptual understanding between the GeoGebra and conventional groups (p < .001), with a moderate-to-large effect size (r = 0.44). These results provide classroom-based empirical evidence that dynamic visualization through GeoGebra strengthens students’ conceptual understanding and supports its structured integration in conceptually demanding mathematics topics.
