Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan pembelajaran visual thinking berbantuan symbolab terhadap peningkatan kemampuan komunikasi dan self-esteem matematis. Metode yang digunakan adalah kuasi eksperimen dengan Non-equivalent Control Group Design. Subjek penelitian ini adalah peserta didik kelas VIII SMPN 54 Bandung jumlah sampel dua kelas, yaitu kelas VIIIA kelas eksperimen sebanyak 28 peserta didik dan kelas VIII C sebagai kelas kontrol sebanyak 28 peserta didik. Instrumen yang digunakan adalah tes kemampuan komunikasi matematis materi persamaan garis lurus dan angket self-esteem matematis sebelum dan sesudah pendekatan pembelajaran visual thinking berbantuan symbolab. Teknik analisis data dilakukan dengan pengolahan data hasil pretest dan posttest yaitu dengan melakukan uji  ternormalisasi kemudian dilanjutkan analisis normalitas dan homogenitas varians. Dilanjutkan dengan uji perbedaan dua rata-rata. Hasil penelitian ini yaitu terdapat perbedaan peningkatan kemampuan komunikasi matematis peserta didik melalui pendekatan pembelajaran visual thinking berbantuan symbolab dengan peserta didik yang menggunakan pembelajaran konvensional, terdapat perbedaan pencapaian kemampuan komunikasi matematis peserta didik melalui pendekatan pembelajaran visual thinking berbantuan symbolab dengan peserta didik yang menggunakan pembelajaran konvensional, terdapat perbedaan peningkatan self-esteem matematis peserta didik antara sebelum dan sesudah mendapatkan pendekatan pembelajaran visual thinking berbantuan symbolab.

Abstract

Mathematical problem solving ability remains a challenge for many students, requiring more engaging learning approaches. This study examined differences in the mathematical problem-solving abilities of Grade 10 students after the implementation of the Problem Based Learning (PBL) model assisted by interactive videos. A quantitative pre-experimental method with a One Group Pretest Posttest Design was employed. The participants were 46 Grade 10 students from a senior high school in Bandung Regency. Data were collected using a validated and reliable essay test administered before and after the intervention. The data were analyzed using the Shapiro Wilk normality test and a paired-sample t-test. The mean pretest score increased from 11.35 to 32.22 out of a maximum score of 50. Statistical analysis revealed a significant improvement in students’ mathematical problem solving abilities after the implementation of the interactive video-assisted PBL model. The findings indicate that integrating interactive videos with PBL can effectively enhance students mathematical problemsolving abilities.

Abstract

This study aimed to describe the validity and practicality of a Science, Technology, Engineering, Art, and Mathematics (STEAM)-based digital storybook for teaching statistics to seventh-grade junior high school students. This study employed a Research and Development (R&D) method using the ADDIE model, which consists of Analysis, Design, Development, Implementation, and Evaluation stages. The validity of the media was assessed by two subject matter experts and two media experts, while its practicality was evaluated through student response questionnaires administered in a small-scale trial involving five students and a large-scale trial involving thirty-five students. The data were analyzed using descriptive statistics in the form of percentages. The results showed that the digital storybook achieved a validity score of 97% from the subject matter experts and 94% from the media experts, both categorized as highly valid. In addition, the practicality test yielded scores of 83% in the small-scale trial and 88% in the large-scale trial, both categorized as highly practical. Therefore, the STEAM-based digital storybook meets the validity and practicality criteria and is suitable for use as a mathematics learning medium for statistics.
