Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman konsep kesebangunan bangun datar melalui kuis interaktif berbasis Quizizz. Kegiatan dilaksanakan di SMP Laboratorium Universitas Pattimura dengan melibatkan 19 peserta didik kelas VII. Permasalahan yang ditemukan adalah peserta didik masih mengalami kesulitan dalam memahami perbandingan sisi, sudut-sudut yang bersesuaian, serta penerapan konsep kesebangunan dalam penyelesaian soal. Pelaksanaan kegiatan dilakukan melalui beberapa tahap, yaitu koordinasi dengan pihak sekolah, penyusunan soal, pemberian pretest, pembelajaran menggunakan Quizizz, review soal, posttest, dan pengisian kuesioner respons peserta didik. Hasil kegiatan menunjukkan adanya peningkatan rata-rata nilai dari 51,47% pada pretest menjadi 63,47% pada posttest. Jumlah peserta didik yang mencapai nilai minimal 60% juga meningkat dari 8 menjadi 13 siswa. Selain itu, respons peserta didik terhadap penggunaan Quizizz berada pada kategori sangat baik dengan rata-rata skor 3,50. Temuan ini menunjukkan bahwa Quizizz dapat membantu menciptakan pembelajaran matematika yang lebih aktif, menarik, dan menyenangkan. Penggunaan Quizizz yang disertai review soal juga dapat mendukung pemahaman konsep, motivasi, dan keterlibatan peserta didik dalam pembelajaran.

Abstract

This study aims to examine the effectiveness of using CODAP on students’ mathematical representation ability in the topic of Linear Equations in One Variable. This study employed a quantitative design with a pre-experimental approach using a one-group pretest-posttest design. The research subjects were 19 eighth-grade students at Pattimura University Laboratory Middle School. The instrument used was an essay test designed to measure three indicators of mathematical representation ability: verbal-contextual representation, visual/graphical representation, and symbolic representation. The data were analyzed descriptively and inferentially using percentage scores, N-Gain, the Shapiro–Wilk normality test, the paired sample t-test, the Wilcoxon signed-rank test, and effect size analysis. The results showed that CODAP-assisted learning improved students’ abilities across all measured indicators. Verbal-contextual representation increased from 80.89 to 96.84, with an N-Gain of 0.483; visual/graphical representation increased from 47.37 to 86.84, with an N-Gain of 0.556; and symbolic representation increased from 0.00 to 56.21, with an N-Gain of 0.562. All improvements were categorized as moderate, yet they were statistically significant, with large to very large effect sizes. These findings indicate that CODAP helps students interpret contextual problems, read graphical representations, and construct mathematical models more meaningfully in the topic of linear equations in one variable.

Abstract

Mathematical representation ability is the ability to present notations, symbols, tables, pictures, graphs, diagrams, equations, or other mathematical expressions into other forms possessed by students to find solutions to a problem at hand. Therefore, teachers should provide sufficient opportunities for students to be able to train and develop mathematical representation skills as an important part of solving the problems given. The mathematical representation ability of students is still low. Students still find it difficult to solve mathematical problems related to aspects of verbal indicators, picture indicators, and symbol indicators. This can be found in linear programming material. Also, linear programming material is often considered difficult material by students in learning mathematics. This study aims to describe students' mathematical representation abilities including symbol representation, image representation, verbal representation on linear programming material in class XI SMA Negeri 3 Ambon. The type of research used is combination research (mixed methods). The research was conducted at SMA Negeri 3 Ambon with 36 research subjects from class XI MIPA 4 and the subjects chosen to be interviewed were based on the results of the mathematical representation ability test. From the results of the mathematical representation ability test on linear programming material, students are grouped based on the very high, high, medium, low, and very low categories. The subjects interviewed were 1 student with a very high category; 1 student with a low category, and 1 student with a very low category. Linear programming material is given to help students improve mathematical representation abilities. The largest percentage of students' test results are in the very low category. Based on the test results, it shows that the mathematical representation ability of students on symbol representation is higher than image representation and verbal representation. Meanwhile, from the three subjects interviewed, it was found that subjects tended to fulfill the indicator of symbol representation ability compared to the indicators of image representation and verbal representation
