Abstract

This study aims to investigate the effect of guided inquiry and Student Teams Achievement Division (STAD)-type cooperative learning models on students’ mathematical communication ability. A quasi-experimental method with a pretest-posttest control group design was employed. The sample consisted of two eighth-grade classes selected through cluster random sampling from a junior high school in Bandar Lampung. Students in the experimental class received instruction using the guided inquiry model, while those in the control class were taught using the STAD-type cooperative model. A mathematical communication test, consisting of items aligned with three key indicators—written explanations, symbolic expressions, and visual representations—was administered before and after the intervention. Data were analyzed using an Independent Samples t-test. The results revealed a statistically significant difference in posttest scores between the two groups (t = 2.844, p < 0.05), favoring the guided inquiry model. Additionally, students taught through guided inquiry demonstrated greater improvements across all indicators of mathematical communication, particularly in their ability to explain reasoning through structured written responses and to use appropriate mathematical symbols.

Abstract

The concept of angle and angular measure are essential concepts that need to be well understood in learning geometry. However, students often misunderstand these concepts. This study aimed to analyze how the shift in knowledge of the concept of angle and angle measurement in the perspective of didactic transposition. A qualitative study with a phenomenological approach was conducted to examine this phenomena. Data were collected through classroom observation, interviews, and documentation studies. The results of the study indicate that the transposition process in learning affects students' conceptualization process of the definition of angles so that students cannot distinguish between angles and anglular measure and tend to consider the two to be the same. A weak transposition process often causes errors, variations in meaning, and limited knowledge. This study emphasizes the need for a good didactic approach to bridge the gap in the transition process between scientific knowledge of mathematics and students' understanding. The implications of this study suggest that there is an alignment of both the curriculum and teaching materials that are in line with scholarly knowledge to improve students' understanding of the concept of angles and anglular measure.

Abstract

Higher-Order Thinking Skills (HOTS) are essential abilities that students must possess in order to face complex problems and think critically. The role of learning models is crucial in developing students' HOTS, as they provide structured and meaningful learning experiences. Numerous learning models have been applied to facilitate and improve students’ higher-order thinking, particularly in mathematics. This study employed a Systematic Literature Review (SLR) approach, which involved collecting and analyzing previously published articles indexed by Google Scholar. The articles were gathered using the Publish or Perish software, with keywords such as "learning model," "HOTS," and "mathematics." A total of 25 relevant articles were reviewed. The findings revealed that several learning models have proven effective in enhancing students' HOTS, including Problem-Based Learning, Project-Based Learning, Discovery Learning, Creative Problem Solving, CORE, and Missouri Mathematics Program. The specific HOTS skills improved through these models include critical thinking, creative thinking, reasoning, and problem-solving abilities. The implication of this study is that educators are encouraged to design instructional activities using learning models with proven effectiveness in fostering students' higher-order thinking skills.

Abstract

The Industry 5.0 era demands mathematics learning models that are not only technology-enhanced but also culturally responsive and competence-oriented. This systematic literature review investigates the integration of technology-supported problem-based learning (PBL) with culturally responsive teaching (CRT) in mathematics education. Following the PRISMA 2020 protocol, 24 records were retrieved from Scopus, ScienceDirect, and Google Scholar; five met the inclusion criteria and were thematically analyzed. Results show that PBL supported by technology improves students’ problem-solving skills, mathematical literacy, motivation, and self-regulated learning. However, explicit integration of CRT within these models remains limited. Compared to conventional approaches, a combined PBL-CRT-technology framework holds greater potential to promote meaningful, inclusive, and future-oriented mathematics learning. This review recommends the development of a comprehensive instructional model that aligns cultural relevance, digital innovation, and inquiry-based learning. Implications for research and practice are outlined to support mathematics education in diverse and digitally connected learning environments.

Abstract

Mathematical representation is a fundamental skill in mathematics learning, allowing students to express and solve problems through symbolic, verbal, and visual forms. However, students' varying levels of mathematical ability can significantly influence the quality of their representational skills. This study employed a descriptive qualitative method involving three eighth-grade students from SMPN 2 Kasimbar, selected based on their mathematical abilities: high, medium, and low. Data were collected through tests and semi-structured interviews, and analyzed using data condensation, data display, and conclusion drawing techniques. The results indicated that high-ability students could construct and solve systems of linear equations in two variables, although they exhibited some difficulty in interpreting variables accurately. Medium-ability students demonstrated proficiency in formulating equations and performing calculations, with particular strength in verbal and visual representations. In contrast, low-ability students struggled with algebraic operations, often misused variables, and were unable to generate appropriate graphical representations. These findings highlight the significant role of mathematical ability in shaping students’ representation skills and underscore the need for teachers to implement more adaptive and differentiated instructional strategies.

Abstract

Indonesia is a tropical archipelago located along the equator, where air temperature patterns exhibit seasonal trends and unstable fluctuations. This instability can impact several sectors, including agriculture—making it difficult for farmers to determine planting and harvesting times—electricity demand, which increases during hotter periods, and public health, as erratic weather may reduce productivity and elevate the risk of diseases such as dehydration, asthma, and respiratory infections. This study aims to evaluate the performance of the Trigonometric, Box-Cox Transformation, ARMA Errors, Trend, and Seasonal (TBATS) model and the Seasonal Autoregressive Integrated Moving Average (SARIMA) model in forecasting air temperature in Indonesia. The dataset used comprises 2-meter air temperature records in Indonesia from January 1940 to August 2024, obtained from ECMWF. The evaluation method applied is cross-validation with a rolling basis. The results show that the RMSE for the TBATS model is 21.3843%, while the SARIMA model has an RMSE of 21.2958%. These results indicate that SARIMA has a slightly better performance than TBATS. However, both methods perform well in forecasting air temperature in Indonesia, as their RMSE percentages are within an acceptable range. This research is expected to contribute to the scientific literature on air temperature forecasting in Indonesia and encourage further studies on hybrid models that integrate TBATS and SARIMA. Additionally, it may support efforts to mitigate the adverse impacts of air temperature changes in the country.

Abstract

This study aimed to examine how the integration of GeoGebra in problem-based learning influences mathematics learning outcomes, taking into account students' learning interest. The study was motivated by low student achievement and the limited use of technological innovation in mathematics instruction. A quasi-experimental method with a Post-Test Only Control Group Design was employed, using a quantitative approach. The participants were 9th-grade students at SMP Muhammadiyah 5 Surakarta. Two classes were selected through cluster random sampling to represent the overall 9th-grade population. The sample consisted of class IX-C, which served as the control group and received PBL without GeoGebra, and class IX-D, which served as the experimental group and received PBL integrated with GeoGebra. The research instruments included a learning interest questionnaire and a mathematics learning outcome test. Data were collected through a post-test and a questionnaire using a 4-point Likert scale. A two-way analysis of variance (ANOVA) with a 2×2 factorial design was used for data analysis. The findings indicated that: (1) the integration of GeoGebra into the PBL model had a significant effect on students' mathematics learning outcomes; (2) students’ learning interest significantly influenced their learning outcomes; and (3) there was no significant interaction effect between the learning model and learning interest. These results suggest that applying PBL with GeoGebra is an effective instructional innovation in mathematics teaching, particularly for the topic of Similarity, and that the integration of GeoGebra can enhance students’ mathematics learning outcomes.

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

Mathematical representation ability is an important skill for students to transform complex problems into simpler forms. However, field observations based on the pretest results of mathematical representation ability conducted at SMP Negeri 18 Bandarlampung show that many students have not yet mastered this skill. This is supported by the 2022 PISA results, which indicate that students’ mathematical representation ability is still categorized as low. Therefore, it is necessary to apply a learning model that can help students improve their mathematical representation skills. This study aims to determine the effect of the guided inquiry learning model on students’ mathematical representation ability. The population in this study consisted of all eighth-grade students at SMP Negeri 18 Bandarlampung in the odd semester of the 2024/2025 academic year, totaling 174 students distributed across six classes. Sampling was conducted using the cluster random sampling technique, selecting class VIII B (28 students) as the experimental class and class VIII D (29 students) as the control class. The research design used was the pretest-posttest control group design. The data in this study are quantitative data obtained from the students’ mathematical representation ability test. Based on data analysis using the Mann-Whitney U test, it was found that the improvement in mathematical representation ability of students who participated in guided inquiry learning was higher than that of students who followed conventional learning. Thus, the guided inquiry learning model has an effect on improving students' mathematical representation ability.
