Abstract

This study was conducted to compare the two methods of PBL and Ethnomathematics on students' creative thinking skills, and creative thinking abilities in terms of students' initial mathematical abilities. This study aims to determine which learning methods are superior in creative thinking skills. This study uses a quantitative method with a quasi-experimental type of research. The method of data collection is through the initial mathematical ability test and creative thinking ability test. The research subjects are class VII 8 and VII 9 SMP in Kab. Bekasi for the 2022/2023 academic year. Based on the results of the study, it was found that the average value of students in the ethnomathematics class was better than the PBL class. However, for students with high KAM, the PBL method is more effective, because it is proven that the final score of students is higher in the PBL class. Students with medium and low KAM are better at using the ethnomathematical method for their creative thinking skills.

Abstract

Improving student achievement and group-work ability by applying a combination of blended learning and peer learning as the aim of this research. This research was conducted in March – July 2022. This type of research is classroom action research which consists of cycles, where each cycle has 4 stages, namely: planning, implementation, observation and reflection. This research was conducted on 8 4th semester students of the mathematics study program for the 2021/2022 academic year who took the Introduction to Demographics course. Data collection techniques used are tests and observations. The results of this study are 1) improving the results of learning achievement seen from the class average value from before the study, which was 57.87 and after the study consisting of cycle I and cycle II with an average grade of 71.5 and 80.25. 2) improve the ability of student group-work in several criteria, namely: student activity in learning, better communication methods, student contributions and responsibilities to the tasks given in groups, and the ability to express opinions/ideas. This is indicated by the results of the group-work ability data which before the research students were included in the criteria of not being good (37.5%), quite good (50%), and good (12.5%). After the action, the students were categorized as quite good (12.5%), good (25%), and very good (62.5%).

Abstract

The existence of a Student Worksheet (LKPD) is able to improve the ability to understand students' concepts. This research aims to develop LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the ability to understand concepts based on validity, practicality, and effectiveness in geometric transformation materials. The type of research used is research and development (R&D) with a 4D model, namely the defining stage, the design stage, the development stage, and the deployment stage. This study was conducted at SMP Negeri 1 Tegalrejo with a sample of 31 students in class IX B. The results showed that an LKPD based on ethnomathematics of batik motifs typical of Magelang was produced to increase understanding of the concept of geometric transformation that is valid or feasible in terms of the validity value of LKPD by material expert validators and teaching material expert validators, which is 86.31% with a very valid category. Judging from the practicality value of LKPD by the response of students, which is 89.61% with a very practical category. The results of the standard gain increased concept understanding ability were obtained by 5 low classification learners, 10 medium classification students, and 16 high classification students. Increasing understanding of the concept of geometric transformation using LKPD based on ethnomathematics of batik motifs typical of Magelang in terms of the effectiveness value of the pretest and posttest results calculated using the standard gain formula <g> , which is 0.62 with a moderate category, so that LKPD is said to be effective.

Abstract

This study aims to analyze the influence of differences in learning models on problem-solving ability, the influence of differences in student learning styles on problem-solving ability, and the interaction between learning models and student learning styles on problem-solving ability. The design of this study is a pseudo-experimental design. The samples in this study were students of class VII A and class VII C of SMP Negeri 3 Muntilan who were selected by cluster random sampling. Based on the results of the hypothesis test conducted with the two-way ANAVA test, the results were obtained that 1) there were differences in the influence of learning models on problem-solving ability; 2) there is no difference in the influence of the four learning styles on problem-solving ability; 3) there is no interaction between the learning model and the student’s learning style on problem-solving ability. The conclusions of this study are 1) students with ethnomathematics-based PBL models have better problem-solving abilities than students with direct learning models; 2) students with convergent, divergent, assimilated, and accommodation learning styles with an ethnomathematics-based PBL models have better problem-solving abilities than students with direct learning models.

Abstract

This study aims to explore ethnomathematics in the traditional game Galasin in Jakarta on mathematical concepts such as gradients, point to point distance, and vectors. This study uses an ethnographic approach to obtain a description of an in-depth analysis of a culture based on the information that has been obtained and by conducting observations and interviews in data collection. This research focuses on one of the traditional games in Jakarta, namely the Galasin game as a form of understanding ethnomathematics in mathematical concepts such as vectors, gradients, and point to point distances. This shows that the traditional game Galasin in Jakarta has a connection with mathematical concepts and forms of deepening in previous studies which have links with geometric mathematical concepts such as flat shapes. The existence of traditional game media in learning mathematics can provide benefits, namely visualizing mathematics learning in a real form so that students become more understanding and easier to understand learning the mathematical concepts being studied.
