Abstract

The purpose of this study was to analyze students' proportional reasoning ability. The research subjects consisted of 21 students of VIII class in one of the public junior high schools in Semarang City who had obtained comparison materials (ratio and proportion). Data collection used test instruments that were developed based on indicators of proportional reasoning ability consisting of 6 questions. The data were analyzed qualitatively with data reduction analysis procedures, data presentation, and conclusion drawing/verification. The results showed that (1) none of the students met all the indicators of proportional reasoning ability, namely the ability to understand proportional relationships, solve proportional problems of missing values, numerical comparisons, qualitative predictions, distinguish proportional and non-proportional problems, and solve proportional relationships of inverse values, (2) all students have been able to understand proportional relationships, but they are still very limited in their ability to distinguish proportional and non-proportional problems, and solve proportional relationships of inverse value, and (3) the strategy most often used by students to solve proportional reasoning problems is the cross-multiplication strategy.

Abstract

This study aims to reveal the impact of the 6E Instructional 3D geometry model (6E I3DGM) design in improving students' 3D geometric thinking skills. The approach in this study uses a mixed approach. The reason for choosing this approach is that researchers want to get a more comprehensive understanding of this research problem. In this study, the participants involved in this study were (1) junior high school mathematics teachers; (2) grade VIII junior high school students in one of the public junior high schools in Indramayu Regency. In addition, there are three methods of collecting data in this study, namely observation, documentation, tests, which were analyzed using qualitative and quantitative data analysis. Qualitative data analysis using Miles and Huberman (2014) modification consists of data collection, data reduction (data reduction), data display (data display), and conclusion drawing (verification). The statistical test used in this study used an independent t-test. The results of this study conclude that the 6E I3DGM design can improve students' 3D geometric thinking skills. This is because students (1) can activate students' prior knowledge; (2) can relate previous knowledge with prior knowledge; (3) can explore 3D geometry problems; (4) can facilitate the process of constructing new concepts of 3D geometry into students' memory; (5) able to elaborate 3D geometry knowledge acquired in other contexts; (6) can evaluate the acquired knowledge in order that the 3D geometry knowledge possessed by students is stored in cognitive structures for a long period of time.Keywords: 6E instructional 3D geometry model, 3D geometry thinking skills, junior high school students.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp45-56

Abstract

This study aims to analyze the role of technology in facilitating the development of students' proportional reasoning skills in mathematics learning. This study used the systematic literature review method with a qualitative approach. Documents on the Scopus database were analyzed according to the research objectives using the PRISMA 2020. Thematic analysis was applied to all documents included in the search results. The results of this study indicated that there were 18 documents found that addressed the chosen topic-first in 2006, with 2015 being the most productive year discussing this topic. The technologies used to facilitate the development of proportional reasoning skills are Flash/ActionScript 3 programs-dominated, robotics, web-based learning, interactive touchscreen tablet application (MIT-Ext)-ordered by document quantity, virtual reality (VR), GeoGebra, video games, and augmented reality (AR). Quantitative, qualitative, and mixed-method approaches were used in almost equal parts. Junior high school was the most researched level of this topic, but no research has been conducted at the senior high school level. The most productive country to research this topic was the Netherlands. The results of this study were expected to provide practical benefits for teachers and future research.

Abstract

Technological Pedagogical Knowledge (TPK) is a skill that combines pedagogical and technological competencies to support teachers' professionalism in teaching mathematics in the era of digitalization. The purpose of this study is to determine the enhancement of TPK skills among Pre-Service Mathematics Teachers (PSMTs) who studied using a Digital Project Learning (DPL) approach compared to those who learned using a conventional approach. The research method used was an experiment with a posttest-only control group design. The research was conducted in the mathematics education study program at UIN Syarif Hidayatullah Jakarta during the 2023/2024 academic year, with the research sample comprising students from two classes enrolled in Mathematics Learning Strategy (MLS) courses. Seventy-two students enrolled in a mathematics learning strategies course were divided into an experimental group (n=34) and a control group (n=38). The instrument used in this study is a rubric-based observation sheet to assess students' TPK. The results showed that students in the experimental class had better TPK skills compared to PSMTs in the control class. This can be seen in the skills for designing learning and teaching, and in the diversity of technology use. Therefore, DPL is efficacious in improving the TPK skills of PSMTs.
