Various previous studies on the use of the Project-Based Learning (PjBL) model and its impact on mathematical concepts understanding provide varying reports. This research aims to evaluate the impact of the PjBL model on mathematical concepts understanding and investigate its effects based on the type of instructional media. The research method employed is quantitative with meta-analysis, intended to combine, evaluate, and integrate findings from several published studies. Data was collected through documentary studies by searching articles that published in national and international journals. 32 studies met the predefined inclusion and exclusion criteria. Data analysis was conducted using JASP software version 0.18.1.0. The research results indicate that the effect size of the PjBL model on mathematical concepts understanding is significant in the large category. Moreover, statistically, there is significant differences of effect size of the PjBL model depending on the type of learning media used. The implementation of the PjBL model shows a very large effect size on mathematical concepts understanding when using digital learning media and a large effect when using manual learning media. Meanwhile, without using learning media, the effect size of the PjBL model on mathematical concepts understanding is in the medium category.

Abstract

The students’ mathematical literacy skills tend to be influenced by their self-regulated learning. This study aims to analyse mathematical literacy skills based on students' self-regulated learning. The research method used was descriptive-qualitative, involving 40 students from one of the Islamic junior high schools in Bandung Barat, West Java. The instruments used were a PISA-like mathematical literacy problem and a self-regulated learning questionnaire. The data analysis technique used was the Miles and Huberman model. This model uses data collection, data reduction, data presentation, and conclusion drawing. The results showed that students with high and medium level of self-regulated learning had given correct and careful answers related to managing storage on smartphones, but the students with a moderate level of self-regulated learning were careless in performing calculations. While, students with a low level of self-regulated learning have been able to understand the problem carefully, even though they have difficulty finding the right answer. This reseach can be used as one of basis for developing more effective learning strategies that support the improvement of mathematical literacy through empowering self-regulated learning.

Abstract

Students' errors in solving mathematical problems need to be analyzed in depth so that teachers can choose the right way to anticipate the repetition of the same errors. This study aims to reveal the types of errors made by students in solving word problems on the topic of proportion. This study is a descriptive study with a qualitative approach. The subjects involved were two seventh grade students, male and female. The results of this study indicate that based on Newman's error analysis, male subjects mainly made reading errors, errors in understanding the problem, transformation errors, and writing the final answer that did not include a conclusion. While female subjects made errors in understanding the problem, choosing the operation used, and writing the conclusion sentence in the final answers. The results of this study can help students understand the errors made so that the errors are not repeated and can be input for teachers in improving the learning process.

Abstract

Differences in students' learning styles, whether visual, auditory, or kinesthetic, affect the way of students in absorbing, processing, and understanding the mathematical information provided. This statement indicates that differences in learning styles also affect students' mastery of mathematical literacy and students' skills in solving problems involving higher-order thinking skills. So, this study aims to describe students' mathematical literacy skills in solving higher-order thinking skills (HOTS)-oriented problems in terms of students' learning styles. The research used descriptive qualitative research that is involving 6 eighth-grade students at a junior high school in Blora, Central Java, Indonesia, as research subjects selected using simple random sampling techniques. The instruments used were a learning style questionnaire to identify students' learning styles, HOTS-oriented equation of a straight line problems to reveal students' mathematical literacy, and interviews to confirm the answers given by students in the test. Data were analyzed using an interactive model, namely data reduction, data presentation, and data verification, accompanied by triangulation techniques to ensure the validity of the data. The results showed that students with a visual learning style were more dominant in mastering communication skills and the ability to use language and symbolic, formal, and technical operations. In contrast, students with auditory learning styles are only dominant in mastering communication skills. While students with kinesthetic learning styles are more dominant in mastering language use skills and symbolic, formal, and technical operations.

Abstract

This study aims to analyze the content validity of summative assessment items in Combinatorics that are aligned with the Minimum Competency Assessment (MCA) framework. The study was motivated by the need for valid and high-quality assessment tools that support meaningful and sustainable mathematics learning. This study employed a research and development (R&D) design but it focuses primarily on the Develop stage, which aims to obtain a valid summative assessment instrument. The Aiken’s V method was used to measure the content validity of nine multiple-choice items developed according to the MCA numeracy domains, cognitive levels, and contexts. Three mathematics education experts served as validators. The analysis showed that the Aiken’s V indices ranged from 0.64 to 0.73, indicating medium validity. These results suggest that the instrument can be used after minor revisions. The validated instrument provides a reference for educators to design MCA-oriented summative assessments that enhance students’ mathematical literacy and reasoning skills. Future research may apply other validation methods such as Gregory’s analysis to strengthen the evidence of validity.
