Abstract

Mathematical divergent thinking ability is one of the important skills of the 21st century that plays a role in developing students' problem-solving abilities. However, the results of pre-research indicate that students still have difficulty in linking mathematical concepts to real situations and consider mathematics as a difficult subject. This condition indicates the need for innovative, interactive, and interesting learning media to stimulate students' divergent thinking abilities. This study aims to develop a web-based interactive learning media Wordwall that is feasible, interesting, and effective in improving students' mathematical divergent thinking abilities in arithmetic and geometric sequences. This study uses a Research and Development (R&D) approach with the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. The research subjects were grade X students of SMA Ma'arif NU 5 Purbolinggo. Data were collected through interviews, questionnaires, and tests with a One Group Pretest-Posttest design. Data analysis was carried out descriptively quantitatively through feasibility, attractiveness, and effectiveness tests with N-Gain calculations. The results of the study showed that the developed media was declared feasible with an assessment of 90.17% from material experts, 97.2% from test experts, and 90.625% from media experts, with a validation of the media's feasibility reaching 96.42%. Student responses reached 92% with a very interesting category, and the N-Gain analysis of the posttest results showed an increase in the average score of students compared to the pretest with an N-Gain value of 0.53 in the small group test and 0.62 in the large group in the "Medium" category. This study recommends the Wordwall web as an innovative learning medium to foster creativity and improve divergent thinking skills.

Abstract

The demands of 21st-century learning emphasize strengthening logical reasoning and digital literacy, while schools and Islamic boarding schools still lack technology-based bilingual teaching materials that are proven to be valid, practical, and effective..This study aims to develop and test the feasibility, practicality, and effectiveness of bilingual teaching materials (Indonesian and Arabic) on the subject of Two-Variable Linear Equation Systems (SPLDV) through Visual Studio Code (VS Code) to improve students' mathematical logical reasoning. This research is motivated by the low ability of students' mathematical logical reasoning and the limitations of innovative learning resources that integrate bilingual aspects and digital technology. The method used is Research and Development (R&D) with the ADDIE model, implemented on grade VIII students at Darul Falah Islamic Boarding School and Nashihuddin Islamic Junior High School in Bandar Lampung. The results of the study show that the teaching materials developed are declared Very Valid/Very Appropriate based on expert assessments (material experts 96.88%, media experts 87.5%, and language experts 100%) and are considered Interesting (practical) by students with an average positive response above 80%. Furthermore, the effectiveness test proved that the use of bilingual teaching materials based on Visual Studio Code was significant in improving mathematical logical reasoning, as evidenced by the average N-gain value which was in the medium category (Small Trial 0.563 and Large Trial 0.596). Thus, it can be concluded that bilingual teaching materials through Visual Studio Code are feasible, practical, and effective to be used as a learning innovation to improve students' mathematical logical reasoning abilities.
