Abstract

The aim of the research is to develop comic media to determine the validity, practicality and potential effects of the comic media being developed. The type of research applied is Research and Development (R&D) with the ADDIE method which consists of Analyze, Design, Development, Implementation and Evaluation. The research results from the development of comic media on energy source materials were valid. It can be seen from the assessment results from media, material and language experts, obtaining a percentage of 87% with the criteria "Very Valid". Based on the value given by the validator, comic media can be stated valid to be used in the learning process. The results of the development of comic media can be seen from the student responses in the one to one trial which obtained a percentage of 8.3% with the "Very Practical" criterion, while the student response in the small group trial obtained a percentage of 8.8% with the "Very Practical" criterion", and student responses in the field test which obtained a percentage of 8.7% with the criteria "Very Practical" based on responses from students, the comic media can be stated to have practicality. The results of developing comic media were stated effective. It can be seen from the results of research in field trials which obtained a pre-test score of 7.9% and a post-test score of 9.1% with the criteria "Very High”.

Abstract

Effective learning planning requires information on the obstacles to learning a given concept that students experience to create a learning flow that matches the students’ characters, including in the learning of the concepts of relations and functions. The research aims to determine the learning obstacles (LOs) that students experience in learning the concepts of relations and functions as per the criteria of the theory of didactic situations (TDS). Employing the case study method, this qualitative research was conducted with subjects that included 19 prospective teacher students who had taken a diagnostic test and participated in in-depth interviews. An analysis was conducted based on three TDS criteria, namely action, formulation, and validation. The results revealed two types of LOs that students experienced in learning the concepts of relations and functions: 1) ontogenic obstacles and 2) epistemological obstacles. The first type of obstacles included 1a) the inability to properly understand the definition of the intersection of two relations, referred to as conceptual ontogenic obstacle, and 1b) the inability to relate the concept of relations in drawing a Hasse diagram, referred to as instrumental ontogenic obstacle. Meanwhile, the second type included 2a) the difficulty in expressing relations in the forms of mapping diagrams and graphs, 2b) the difficulty in determining the range of ​​a function, 2c) the difficulty in identifying relations which are also functions, 2d) the inability to represent relations in the forms of mapping diagrams, and 2e) the inability to write a function as a set of ordered pairs. It is recommended that these LO findings be taken into consideration in designing learning tools.

Abstract

This research aimed to produce a valid and practical product in the form of a student worksheet using the Indonesian version of the Realistic Mathematics Education (PMRI) approach in the classroom context with an orientation toward students’ conceptual understanding and to figure out the potential effect of the student worksheet developed. It is a piece of development research under the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. Data collection was performed using documentation, a questionnaire, and a test. The object of this research was the development of a student worksheet using the PMRI approach within the classroom context with an orientation toward students’ conceptual understanding. Meanwhile, the subjects of the research were students of grade X of SMAN 06 Banyuasin. The research results showed that the student worksheet produced was declared valid (with an average score of 90.83), practical (based on the students’ questionnaire responses, with a score of 79.65), and potentially influential to a high degree (based on the students’ test results, with a percentage of 84%). Therefore, the student worksheet that was developed using the PMRI approach within the classroom context with an orientation toward students’ conceptual understanding was worth using in the learning process.DOI : https://doi.org/10.22342/jpm.16.2.14854.203-214

Abstract

Statistics is often considered a challenging subject, where high levels of anxiety can hinder understanding of the material, affect results, and hinder the development of statistical skills. This study aims to analyze effectiveness of four learning strategies namely tutorial learning, presenter learning, project online learning, and project face to face learning in improving students' statistical literacy skills. This study used a quantitative approach with a posttest group design research design involving 140 students who were divided into four treatment groups. The analysis technique used is MANOVA (Multivariate Analysis of Variance) with the stages of normality test, homogeneity, multiple comparisons, and Tukey HSD further test. The results show that Tutorial Learning, Presenter Learning, and Project Face to Face Learning strategies have a more significant impact on improving statistical literacy. The three strategies showed relatively balanced effectiveness in improving students' statistical skills. This finding confirms the importance of selecting appropriate learning strategies to promote a deep and meaningful understanding of statistics. This research provides an empirical contribution to the development and selection of appropriate learning strategies, especially in statistics education at the tertiary level. It also recommends further exploration of innovative, contextual, and adaptive combinations of learning strategies to students' needs.

Abstract

Although critical thinking is vital in 21st-century learning, mathematics classes often emphasise procedures over reasoning. Few studies have explored how students’ characteristics (learning styles, thinking habits, and cognitive abilities) interact with contextual learning approaches such as Pendidikan Matematika Realistik Indonesia (PMRI). This study aimed to describe the students’ critical thinking using PMRI as a learning approach, specifically by analysing how these abilities vary based on students’ learning styles, thinking habits, and cognitive ability levels. The context of water pH was used to explore the measures of central tendency. Students were observed based on their learning styles, thinking habits, and cognitive abilities. This study used a descriptive qualitative method with 29 eighth-grade students from junior high school in Palembang. Data were collected through tests, questionnaires (learning styles and thinking habits), and the participants’ academic records. The data were analysed using Miles, Huberman, and Saldana’s model, which involves data reduction, presentation, and conclusions. The results show that female students tend to possess “quite critical category”, while male students also show “quite critical category” category when analysed by learning style, but lower in thinking habits and cognitive ability. This implies that teaching should consider students' differences to support the development of critical thinking.

Abstract

This study aims to design a contextual learning trajectory using water pH as an anchor to help student’s understand central tendency concepts, including mean, median, and mode. The research employed a design research approach within a qualitative descriptive framework, consisting of three main stages: preliminary design, design experiment, and retrospective analysis. In the preliminary design stage, a Hypothetical Learning Trajectory (HLT) was developed and aligned with the learning objectives, ensuring that the tasks were suitable for fostering students' understanding of the central tendency concepts. The design experiment involved data collection from a pilot experiment with 6 students and teaching experiment with 29 eighth-grade students at the junior high school. Data was gathered using instruments, including student worksheets, video recordings, field notes, and test. The data collected from students’ responses were analyzed to assess their understanding of the concepts. In the retrospective analysis stage, the Actual Learning Trajectory (ALT) was compared with the predicted HLT to identify any discrepancies and assess the effectiveness of the learning activities. The results showed that integrating the PMRI approach with Project-Based Learning (PjBL) successfully engaged students and contributed to their conceptual development, reinforcing the importance of using contextual problems such as water pH in teaching statistical concepts.
