Abstract

Problem solving is a process that requires logical thinking to find solutions to the problems faced. Through this process, students will learn to develop appropriate strategies to solve the problems. This study aims to identify errors made by students in solving problems on the material of function derivatives. The method used in this study is descriptive qualitative, with data collection techniques carried out through previous literature reviews. The results of the study showed that students made mistakes at several stages, namely in understanding the problem, designing a solution strategy, implementing the solution, and at the re-checking stage. Based on the type of error, students made mistakes in terms of facts, concepts, principles, and operations. The proposed solution is to accustom students to be more careful in solving problems based on problem-solving steps, especially at the final checking stage, and to improve their mastery of algebraic operations and basic factoring techniques.

Abstract

The role of mathematics teachers in the success of the learning process can be seen from the perspective of the work period, which reflects the level of experience. Therefore, this research aims to analyze the comparison of the implementation of the mathematics learning process from the perspective of the teacher's work period. The type of research carried out in this study is qualitative descriptive research. The subjects in this research were 2 mathematics subject teachers at one of the state junior high schools in South Lampung, with the criteria being 1 junior teacher and 1 senior teacher. Data collection techniques use participant observation, interviews, and documentation. The implementation of the learning process is measured using instruments in the form of observation sheets and interview guides. The observation sheet uses the Guttman scale and the Likert scale. The data analysis technique uses Miles and Huberman's steps, which consist of data collection, data presentation, data reduction, and verification or drawing conclusions. Based on the research results, it was found that both junior and senior teachers had good criteria for implementing the mathematics learning process. So, it can be concluded that differences in teachers’ work periods do not affect the process of implementing mathematics learning. Based on these results, support from the school must play an important role. Both junior and senior teachers must receive sufficient support from school management, continuous training, and guidance so that they can achieve good criteria in implementing the mathematics learning process.

Abstract

One of the essential skills students must develop in mathematics learning is mathematical communication. However, field observations indicate that students still exhibit weaknesses in this area. Therefore, it is necessary to implement a learning model supported by digital media that facilitates students in expressing and communicating mathematical ideas more effectively. The guided inquiry learning model, when integrated with interactive media such as Desmos, offers a promising alternative. Desmos is a dynamic graphing application that allows students to explore mathematical concepts visually and interactively, thereby supporting deeper conceptual understanding and communication. This study employed a quasi-experimental design aimed at examining the improvement of students’ mathematical communication skills through the implementation of a guided inquiry learning model with Desmos. The population consisted of all ninth-grade students at SMP Negeri 45 Bandar Lampung in the 2024/2025 academic year, totaling 107 students across four classes. The samples were selected using a cluster random sampling technique and comprised class 9.3 (27 students) as the experimental group and class 9.2 (26 students) as the control group. The research design used was a posttest-only control group design. Quantitative data were collected through a mathematical communication skills test. Based on hypothesis testing using an independent sample t-test at a significance level of α = 0.05, the results showed that t-count > t-table (2.08 > 1.67). Thus, it can be concluded that the application of the guided inquiry learning model with Desmos significantly improves students’ mathematical communication skills.

Abstract

This quasi-experimental study aimed to investigate the effect of the Guided Discovery Learning (GDL) model on the mathematical reasoning ability of eighth-grade students. The population consisted of 319 students from Grade VIII at SMP Negeri 20 Bandar Lampung during the 2024/2025 academic year, distributed across ten classes (VIII-A to VIII-J). Using a purposive sampling technique, two classes were selected as research samples: class VIII-B (32 students) as the experimental group, which received instruction using the GDL model, and class VIII-A (32 students) as the control group, which received conventional cooperative learning. The study employed a pretest-posttest control group design. The research data were quantitative, obtained through a mathematical reasoning ability test on the topic of Systems of Linear Equations in Two Variables, administered before and after the intervention in both groups. Statistical analysis using an independent samples t-test on the gain scores revealed a statistically significant difference. The findings showed that students in the GDL group experienced greater improvement in mathematical reasoning ability compared to those in the control group. These results suggest that the GDL model has a positive and significant effect on enhancing students’ mathematical reasoning skills.

Abstract

This study aims to develop a valid and practical LKPD (Student Worksheet) for use in the mathematics learning process on the topic of geometric transformations. The novelty of this research lies in the integration of the scientific approach and geogebra in teaching geometric transformations. The scientific approach has been proven to enhance problem-solving skills, while geogebra improves concept understanding and problem-solving abilities. The integration of both in the developed LKPD is expected to enhance students' problem-solving skills in an interactive and technology-based manner. The research method used is Research and Development (R&D) with the adaptation of the ADDIE development model. Data collection techniques in this study include interviews, observations, and questionnaires. The data collection instruments consist of interview guidelines, expert validation questionnaires, and response questionnaires. The results of the research have been analyzed and validated in terms of content, media, and language aspects. Additionally, an analysis of the practicality of the LKPD was conducted by teachers and students who used it in the learning process. The validity score for the content aspect from Validator 1 was 80%, categorized as valid, Validator 2 was 71%, categorized as valid, and Validator 3 was 80%, categorized as valid. For media and language aspects, the evaluation from Validator 1 was 66%, categorized as valid, Validator 2 was 61%, and Validator 3 was 85%, categorized as very valid. The analysis of LKPD practicality by teachers and students showed that the LKPD was considered practical, with a practicality score of 84.4% from the teacher (categorized as practical) and 90.8% from the students (categorized as very practical).
