Abstract

The 2018 PISA results show that Indonesian students' numeracy and literacy skills are poor. Epistemological beliefs, beliefs in mathematical knowledge, are one of the factors contributing to poor student literacy skills. This study analyzes epistemological beliefs in solving translation problems of Year 9 students in one of the junior high schools in Manipa Islands, Indonesia. This research employed a descriptive a qualitative approach. The subjects in this study were students who tend to meet the indicators of epistemological beliefs. Data collection techniques were observation, tests, interviews, and documentation. The results showed that students' epistemological beliefs in completing the translation met the requirements. First is being able to solve mathematical problems by taking time, where students needed time to solve the problem. This is because students are not sure that they can solve them. Second, students can solve problems that cannot be solved with simple, step-by-step procedures, where students solve problems using their rules/settlement procedures. The third is understanding essential concepts in mathematics, where students understand and work on translation problems using mathematical concepts well. Fourth, word problems are essential in mathematics, with word problems, students can improve critical thinking skill. Finally, efforts can improve mathematical abilities, where students can try to solve problems to improve their math skills. Efforts include reviewing the lesson and increasing practice questions.

Abstract

The literature on the effect of the Realistic Mathematics Education (RME) approach on high-order thinking skills (HOTS) students is massive. There is a diversity of research results. So a systematic and comprehensive review is needed to justify and describe its effect, which includes problem-solving, critical, creative, and reasoning abilities. This research used a systematic literature review (SLR) technique to search the Semantic Scholar, ERIC, Google Scholar database, and direct URLs from 2013 to 2022, yielding 49 studies that matched the inclusion criteria. Every paper was recorded and then categorized for analysis based on the title, education level, year of publication, sample size, and kind of HOTS. The findings indicated that RME positively impacted students' HOTS when learning activities were applied with student-centered, contextual problems, and the teacher was the facilitator. Working together in small groups allowed students to carry out individual exploration activities, reconstruct concepts from their own experiences, and connect these concepts to the mathematical ideas studied. RME thus becomes appropriate for use in achieving learning's aims and urgency, particularly in raising students' mathematical HOTS. The study's findings also offer information on the trends and heterogeneity of research into applying RME on mathematical HOTS in Indonesia. It is thus anticipated that it will serve as a recommendation and a focus for further study.

Abstract

In studying geometry, it is common for students to make various errors when working on word problems. Although some students understand the example problems, they may be confused and make errors when presented with different questions. This study employed a qualitative descriptive approach to examine the types and causes of errors made by Grade 8 students from a junior high school in Pronojiwo, Indonesia. The study involved 40 students, with six students selected for interviews. Data were collected using descriptions and interviews. The research employed three procedural stages: preparation, implementation, and data analysis. Data analysis involved data reduction, data encoding, and conclusions. The analysis revealed that 23.3% of students made conceptual errors, 27% made procedural errors, and 44.5% made technical errors. The factors contributing to these errors included students' lack of focus on reading the questions, limited understanding of the material, haste in completing the questions, insufficient knowledge of the problems in the questions, and carelessness in checking their answers.

Abstract

This study aims to investigate the proficiency of prospective mathematics teacher students in mathematical representation. To achieve this goal, we used a qualitative research design with a descriptive approach. The research subjects consisted of three undergraduate students from Mathematics Education department at a private university in Yogyakarta. Data were collected using a test for mathematical representation ability and interviews. The data were analysed descriptively using techniques by Miles and Huberman. It shows that the mathematical representation ability of prospective teacher students was in low category. This can be seen from the average achievement of indicators of mathematical representation ability (34.74%). The ability to create and use representations for collecting/organizing, recording, and communicating mathematical ideas is 33.33%. The ability to select, apply and translate various forms of representation mathematics to solve problems is 29.76%. And the ability to use multiple representations is 41.11%.

Abstract

This study employed GeoGebra to develop interactive learning instruments for SLETV content, using the 4-D Thiagaradjan model as the framework, involving four phases: define, design, develop, and disseminate. The investigation included two eighth-grade math teachers and fourteen-year-old eighth-graders, and observational data were collected through needs analysis, interviews, and questionnaires. The data collection comprised need analysis, interviews, and surveys. Before trial implementation, three crucial development requirements had to be met: validity, practicality, and efficacy. The validation of learning instrument formats, illustrations, language, and content showed valid. The research findings indicate that the developed learning instruments were effective, with an average student score of 74.3 on the pretest and 87 on the posttest (meeting the minimum criteria of mastery learning). Teacher's ability to manage learning was rated as very good, with an average score of 4.4. The observation of learning implementation showed an average score of 4.4 in the very good category (practical). The learning instruments based on RME can be used to enhance students' mathematical literacy and learning interest.

Abstract

The study investigated the influence of the Treffinger learning model and self-directed learning on the critical thinking skills of junior high school students. The Treffinger learning model is one of the few models addressing the problem of creativity and providing practical suggestions on how to achieve cohesion. On the other hand, self-directed learning is a mental process to increase the knowledge, skills, and self-achievement of individuals with self-planned and self-conducted activities. The research employed a post-test experiment and control group design with two groups. The study employed two groups; one group was treated using the Treffinger learning model, while the other group was treated using a conventional model. Both groups were analyzed using a self-directed learning questionnaire and a critical mathematical thinking skills test. The sample of this research comprised 88 Grade 8 students purposefully selected in relation to the research objectives. The results of the study showed that the Treffinger learning model was statistically significant in enhancing critical mathematical thinking skills compared to the conventional learning models. Additionally, the study found that students who exhibited high levels of self-directed learning were more likely to benefit from the Treffinger learning model than the conventional model, with a statistically significant mean difference of 3.05 points.

Abstract

The guided inquiry learning model is a student activity that emphasizes maximally training critical thinking skills. The learning instruments developed must be adapted to the syntax/stages of the guided inquiry learning model. Several learning instruments have been developed to assist teachers in making teaching materials. However, many teachers have not mastered technology, especially learning media using applications. Therefore, teachers need learning applications in schools, such as the GeoGebra applet. This study aims to develop valid guided inquiry-based learning instruments using GeoGebra applets for circles. This research is development research employing Plomp’s model and involving preliminary research and prototyping stages. The data was collected by compiling the comments and input from the validator through validation sheets related to learning instruments (lesson plans, worksheets, and GeoGebra applets). The results of the data analysis showed that the learning instruments were declared valid with an average lesson plan score of 4.75, an average student worksheet validation score of 4.60, and an average value of the total validation of GeoGebra applets of 4.94. Further research should assess the practicality and effectiveness of the instruments.

Abstract

Teachers often face challenges in creating effective learning materials, particularly in mathematics. Traditional lecture methods and insufficiently engaging learning tools can lead to student disinterest. Hence, it is essential to develop mathematics learning media that stimulate interest and connect to real-world experiences, including local cultural practices. Therefore, this study aimed to design effective learning media for Year 8 students focused on number patterns and to assess the validity of this media. This research adopted a development approach, utilizing the Analysis, Design, and Development (ADDIE) method. The development process was limited to the Analysis, Design, and Development stages. An assessment questionnaire was used to evaluate the validity of the video media, with input from both media experts and material experts. Five experts from each field were consulted for media validation. Results of the validation process indicated that the video media scored 88% and 87% in the material expert and media expert evaluations, respectively. These scores met the criteria for validity, indicating that the media is suitable for use in the classroom.
