PENGARUH MEDIA TRANSGO TERHADAP PEMAHAMAN KONSEP TRANSFORMASI GEOMETRI PADA SISWA SMP

Isti Hari Wahyuni — 2024-05-29

This research was motivated by problems in the field regarding the difficulties of junior high school students in understanding geometric transformation material. This research was carried out at Bhara Widya Catholic Middle School Lumajang in accordance with the results of observations which showed that learning media had never been used to instill the concept of geometric transformation. The aim of this research is to determine the influence of using Transgo media on understanding the concept of geometric transformation in class IX students at the school. This research is an experimental type of research with a quantitative design, posttest only control design. The instrument used was a comprehension test and the data was analyzed using inferential statistics. The results of the research show that there is a positive effect of using Transgo media on understanding the concept of geometric transformation in class IX students at Bhara Widya Catholic Middle School, which is known through the Asymp.Sig (2-tailed) value of 0.000 < 0.05 with an influence of 28.87% (more than 20%). Transgo media can be implemented in learning in other locations to increase students' understanding of geometric transformation material.

EKSPLORASI NILAI MATEMATIKA PADA TINGKATAN TELUR MAULID CIKOANG TAKALAR

Andi Mulawakkan Firdaus — 2024-05-29

Mathematics as part of learning, requires daily life such as culture to be used as a learning source. One of the Takalar cultures is the celebration of Cikoang mawlid, also cannot be separated from mathematics. This celebration contains mathematical concepts, especially at the egg level. The aim of this research is to explore mathematical concepts found at the Cikoang mawlid egg level in Takalar district. This research uses an ethnographic approach. Data collection was carried out using literature review, observation and interview techniques. The results showed that at the egg level, the concept of arithmetic sequences and series was found. Furthermore, this concept can be developed to become part of mathematics learning.

ANALISIS KEGAGALAN PENALARAN KOVARIASIONAL MAHASISWA DALAM MENGONSTRUKSI GRAFIK FUNGSI

Barep Yohanes — 2024-05-29

This research aims to identify failures in covariational reasoning of mathematics education students in the Numerical Methods course. This research is descriptive qualitative type with the researcher as the main instrument and supporting instruments in the form of assignment sheets, interview guides and documentation. The research subjects were 18 students from the Mathematics Education study program, FMIPA, PGRI Banyuwangi University. The work results are grouped into 5 based on the type of function graph created, namely subjects without function graphs (4 students), graphing linear functions (5 students), graphing quadratic functions (6 students), graphing polynomial functions (1 student), and graphing circle functions (2 students). Covariational reasoning failures are identified based on the 5 mental actions that Carlos has compiled. The results showed that there was failure of mental action 1 in groups 1 subjects; 2nd mental failure in subjects groups 1 and 5; 3rd mental failure in subjects groups 1 and 4; 4th mental failure in subjects groups 1 subjects and 3, and mental failure 5 in subjects groups 1 and 2. Research can be continued by exploring aspects of the causes of failure in covariational reasoning.

ANALISIS BIBLIOMETRIK TREN GLOBAL KOMUNIKASI MATEMATIKA DALAM PENDIDIKAN (1995-2023)

Allisa Madepera — 2024-06-25

This research aims to provide information related to global research trends on mathematical communication. A bibliometric study was used to see the development of international articles on mathematical communication from 1995 to 2023 through the Dimensions database. This research uses a bibliometric analysis method through the flow diagram stages of Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The results of this research show that mathematical communication is still a topic of interest for research, with the article entitled “There is more to discourse than meets the ears: Looking at thinking as communicating to learn more about mathematical learning” by Anna Sfard being the article with the most citations. The most articles in the SDGs are in the field of quality education, while the AIP Conference Proceedings is the publication that contains the most mathematical communication topics. Apart from that, it is also known that Yus Mochamad Cholily is the writer with the highest productivity on the topic of mathematical communication. The terms related to mathematical communication that are most popular in research are: cognitive style, PJBL, linear equations and mathematical expression. As for future research, it is hoped that there will be a link between mathematical communication with: emotional intelligence, PjBL and initial ability. The results of the co-authorship analysis show that there is one largest cluster containing eight authors. These results can be the basis for developing further research related to mathematical communication.

IMPLEMENTASI LKPD DENGAN PENDEKATAN RME BERBASIS ETNOMATEMATIKA “GEDRIK” MATERI LUAS BANGUN DATAR

Wiryanto Wiryanto — 2024-06-28

This research aims to determine the effectiveness of student worksheets that use the RME approach based on the ethnomathematics of gedrik game in the mathematics learning process regarding the area of flat shapes. This research allows students to carry out learning activities from contextual situations based on the traditional gedrik game, which is developed into cutting, measuring, calculating, and comparing activities. The method used is descriptive qualitative with a design research type in three stages, namely: preparation, experimental implementation, and retrospective analysis. This research involved five grade 5 students of SDN 1 Ngantru as respondents. The results of the research show that there is a compatibility between the Actual Learning Trajectory and the Hypothetical Learning Trajectory, meaning that the student worksheets with the RME approach based on ethnomathematics of gedrik game is effectively used in understanding students about the area of flat shapes. The results of this research can be tested in other schools at the same level, and developed by utilizing other cultures that are close to students’ daily lives in the form of student worksheets with an ethnomathematics-based RME approach

EFEKTIVITAS LKPD BERBASIS ETNOMATEMATIKA UNTUK MENINGKATKAN KEMAMPUAN PEMECAHAN MASALAH DAN MOTIVASI BELAJAR

Fitriasih Eka Destareiza — 2024-06-28

This research aims to determine the effectiveness of ethnomathematics-based student worksheets teaching materials to improve students' problem-solving abilities and learning motivation. This research was conducted using a pretest-posttest control group design, with an experimental research type. The research population was students in class VII of SMP Negeri 1 Sedayu, while the sample was students in class VII B and VII E. Data collection was carried out using test and questionnaires. Data analysis was carried out using Wilcoxon Ranked-Signed Test, Mann-Whitney U Test, and mean difference test. This method was used because the data obtained was not normally distributed. The results of the research show that the use of ethnomathematics-based student worksheets is effective in increasing students’ problem solving abilities and learning motivation. Further research can be carried out using a larger number of samples or determining a sample with a normal distribution so that the research results can be generalized to the population.
