Abstract

This research aims to identify ethnomathematics in the architecture of the Masjid Agung At-Taqwa Bondowoso which will be used as teaching materials for learning mathematics in the form of a series of stories that can be included in teaching materials in the form of learning videos. This research is qualitative research with an ethnographic approach. This research uses observation and interview methods as research data collection methods. The research subjects consisted of two observers and one resource person, namely the takmir of the Masjid Agung At-Taqwa Bondowoso. The results of the study show that (1) there is a mathematical concept contained in the architecture of the Masjid Agung At-Taqwa Bondowoso (2) the implementation of the two ethnomathematical aspects can be developed into a series of stories that can be contained in a teaching material in the form of learning videos.

Abstract

The research was conducted to design and develop MaCo (Math Comics) learning media based on Realistic Mathematics Education (RME) which is expected to have the characteristics of validity, practicality, and effectiveness in improving learning outcomes and motivating students at the Senior High School (SMA) level. This research applies the ADDIE development model which consists of five main stages, namely Analysis, Design, Development, Implementation, and Evaluation. The results of material validation by material experts showed a percentage of 94% and 92%, while validation by media experts showed a percentage of 92% and 98% which were all included in the very valid category. After going through a revision process based on input from experts, the learning media developed was then tested on grade XI students at SMA Muhammadiyah 3 Jember to evaluate its effectiveness and practicality in supporting the learning process. Based on the results of the students' response questionnaire, a percentage of 86% was obtained which indicated that the learning media was included in the practical criteria. Furthermore, based on the comparison of pretest and posttest scores, an N-Gain value of 0.75 was obtained which was included in the criteria for high improvement in mathematics learning outcomes. While the N-Gain value for learning interest reached 0.55 which is included in the criteria for moderate improvement. Thus, it can be concluded that MaCo (Math Comics) media based on Realistic Mathematics Education (RME) is proven to meet the criteria of validity, practicality, and effectiveness, so it is feasible to be applied in the learning process to improve the quality and learning outcomes of students.

Abstract

This study aims to improve the mathematics learning outcomes of eleventh-grade students on matrices through the application of the Problem-Based Learning model with the Teaching at the Right Level approach. The method used was Classroom Action Research, which was implemented in two cycles. Each cycle included planning, implementation, observation, and reflection. The results showed that in cycle 1, the average student score was 72.4, with a learning completion rate of 53.3%, which did not meet the Minimum Completion Criteria. The main obstacles faced were the imbalance of roles within the group, the lack of participation of low-ability students, and weak mentoring strategies. In cycle 2, after improvements were made through the provision of scaffolding, more structured group management, and task differentiation in the Student Worksheet, there was an increase in the average score to 81.2 with a learning completion rate of 86.7%. In addition, the classroom atmosphere became more collaborative and inclusive, and there was an increase in student confidence and involvement in the learning process. This integration concept can be tested on other materials to determine its effectiveness
