The lack of learning resources and learning media have an impact on reducing the quality of learning. Learning media innovation is needed to provide interactive and joyful learning and integrate cultural context. This research aims to create an ethnomathematics-based electronic module on the topic of number patterns based on ethnomathematics to support students' problem solving skills. This research uses 4D model (define, design, develop, and disseminate). This research involved 29 eighth-grade students from one of the junior high schools in Metro, Indonesia. The research results show that the ethnomathematics-based electronic module on number patterns topic meets the criteria for being suitable for use in learning based on experts review and is able to attract student interest. This fact indicates that ethnomathematics-based modules can be an innovative solution in improving the quality of mathematics learning in the digital era.

Various previous studies on the use of the Project-Based Learning (PjBL) model and its impact on understanding mathematical concepts 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 were 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 are significant differences in the 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.

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.

Newman's Error Analysis: The Students' Errors in Solving Word Problems of Proportion

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 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.

Developing Mathematics Learning Media Using Macromedia Flash 8 to Improve Mathematical Concepts Understanding

The use of appropriate learning media can help students understand abstract concepts and make learning more meaningful and joyful. This study aims to produce learning media based on Macromedia Flash 8 to improve students' mathematical concepts understanding. The development research used follows the ADDIE model, namely analyze, design, development, implementation, and evaluation. The trial of the product prototype involved 27 seventh-grade students of a junior high school in Gresik, East Java. Data were collected using a validation questionnaire of media and material aspects, a student response questionnaire, and a mathematical concepts understanding test. The data were analyzed using quantitative and qualitative methods. The results of the study showed that the learning media was in the very feasible category in terms of material and media aspects. While practicality was obtained from student responses with a good category. In addition, effectiveness was determined based on an increase in mathematical concepts understanding in the medium category. Thus, the Macromedia Flash 8-based learning media that was developed can be used widely, especially on the topic of algebraic forms.
