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

Until now, there have been many studies conducted on mathematical reflective thinking skills presented using problem-based learning models. This study aims to analyze published research on the effectiveness of problem-based learning models on mathematical reflective thinking skills. The method used is meta-analysis. The data analyzed were 8 journal articles that were used to determine the effect size. Data collection was carried out using a variable coding sheet as a coding instrument. The collected data were then analyzed using meta-analytic statistical techniques. The results of the analysis showed that the average effect size of the 8 articles was 2.63, which was included in the high effect size category. Of the 8 articles analyzed, 6 articles (75%) showed a high effect size category, while 2 articles (25%) showed a medium effect size category. The article with the highest effect size, which reached 5.29, shows that the problem-based learning model can provide a very significant increase in students' mathematical reflective thinking skills in learning mathematics.

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.

Abstract

Visual representation is crucial for enhancing students' conceptual understanding of fractions and correcting misconceptions. This explanatory-sequential mixed study assessed Indonesian preservice mathematics teachers' perceptions, self-efficacy, and implementation competencies using visual representations in fraction learning and identified gaps among these three aspects. A total of 251 students from three study programs participated in a validated online survey (α = 0.89). Quantitative data were analyzed using descriptive statistics. Seven participants were then purposefully selected for semi-structured interviews; transcripts were analyzed using Braun & Clarke's six-stage thematic analysis with researcher triangulation. The results showed that although prospective teachers had a very high perception of the pedagogical value of visual representations (M = 4.41; SD = 0.153; 78.9% agreed/strongly agreed), their self-efficacy level was only in the moderate category (M = 3.21; SD = 0.617), with only 28.3% showing high efficacy, and 61.3% were in the medium category. Implementation competence was even lower, with only 17% of participants being able to select and explain visual models pedagogically and 27.8% meeting the sufficient criteria in the teaching reasoning test. The combined analysis of quantitative and qualitative data confirmed the existence of a systemic gap between strong conceptual understanding and limited practical skills, which was mainly caused by uncertainty in model selection, minimal misconception-oriented practical experience, and weak pedagogical reflection. Integrating high-fidelity micro-teaching, representational scenario-based simulations, and video reflections is recommended to enhance self-efficacy and implementation competency.Visual representation is crucial for enhancing students' conceptual understanding of fractions and correcting misconceptions.This explanatory-sequential mixed study assessed Indonesian preservice mathematics teachers' perceptions, self-efficacy, and implementation competencies using visual representations in fraction learning and identified gaps among these three aspects.
