Abstract

This study aims to develop a digital mathematics textbook based on an interactive flipbook format aligned with the Kurikulum Merdeka and accessible across various devices, including smartphones. The research addresses the limitations of conventional printed textbooks in engaging students and supporting differentiated instruction. The development process follows the ADDIE model, encompassing five stages: Analysis, Design, Development, Implementation, and Evaluation. The analysis stage involved identifying curriculum requirements and the preferences of both teachers and students regarding instructional media. The design and development stages produced a digital textbook containing textual materials, instructional videos, interactive animations, external links, and assessments aligned with the Asesmen Kompetensi Minimum (AKM). Validation was conducted by three content experts and one media expert using the Learning Object Review Instrument (LORI), assessing aspects such as content quality, interactivity, and accessibility. The validation results indicated a “highly valid” category, with average scores of 4.51 for content and 4.45 for media. A limited implementation was carried out at two public junior high schools (SMP Negeri) in Kolaka Regency, involving selected teachers and students. The results showed that the interactive flipbook effectively increased student engagement, supported differentiated learning, and enhanced students’ numeracy literacy. Further evaluation suggested that the product is widely applicable, with only minor technical improvements needed. The findings recommend that transforming textbooks from printed to interactive digital formats is an effective strategy for supporting 21st-century learning that is adaptive, flexible, and student-centered.

Abstract

This study aims to examine the effectiveness of the Alef Education platform in improving students' mathematics learning outcomes and their responses to its use at MTs Negeri 1 Kolaka. Alef Education is a digital learning platform that offers instructional videos, educational games, and assessments based on Higher Order Thinking Skills (HOTS). The research employed a post-test only control group design involving two classes: one as the experimental group using Alef, and the other as the control group receiving conventional instruction. Data collection instruments included a mathematics achievement test, student response questionnaires, and interview guides. Quantitative data were analyzed using a t-test, while qualitative data were analyzed descriptively. The results showed that the average learning outcomes of the experimental group were significantly higher than those of the control group (p < 0.05). Students responded positively to the platform, especially appreciating its video lessons and interactive games, which enhanced their conceptual understanding. In-depth interviews also revealed increased student motivation and learning autonomy. These findings suggest that Alef Education is an effective tool for mathematics instruction and holds promise for broader implementation in madrasah as part of digital education strategies.

Abstract

Students with low initial mathematical understanding have difficulty solving mathematical problems especially in Calculus subject that require higher-order thinking skills, one of which is problem-solving ability. Then, problem-solving skills need to be developed using Problem Based Learning models. This study aims to examine the influence of mathematical prior knowledge (MPK) and the problem-based learning (PBL) model on the problem-solving ability of Computer Engineering students at UNIPA in calculus. This quantitative study uses a factorial experimental design. Data were collected through documentation and test instruments, and analyzed using factorial ANOVA with SPSS 23. The results show that students in the PBL class had significantly higher problem-solving ability compared to those in the control class. Furthermore, students with high MPK in the PBL group scored the highest. It can be concluded that both MPK and PBL significantly affect students’ problem-solving ability in calculus.

Abstract

Mathematical problem-solving ability is a fundamental competency in secondary mathematics education; however, many students continue to face significant challenges in mastering this skill. In response, various instructional strategies have been implemented, among which Problem-Based Learning (PBL) has received considerable attention. This study aims to systematically and quantitatively examine the effect of PBL on junior high school students’ mathematical problem-solving abilities through a meta-analytic approach. A total of 24 empirical studies published between 2013 and 2024 were rigorously selected based on predefined inclusion criteria. The meta-analysis results indicate that PBL has a large and statistically significant impact on improving students’ problem-solving skills, with a mean effect size of 0.89, which falls within the high category. Furthermore, the effectiveness of PBL was found to vary across moderator variables, including implementation duration, assessment instrument type, and grade level. These findings suggest that PBL is an effective instructional strategy for enhancing students' critical thinking and problem-solving capabilities. The study recommends broader and more systematic implementation of PBL in schools, as well as targeted teacher training to support its optimal integration into classroom practice.

Abstract

This study aims to analyze the training needs of mathematics teachers in implementing the Merdeka Curriculum through a systematic literature review and online focus group discussions. The background of this research is the limited readiness of teachers in understanding and applying the core principles of the Merdeka Curriculum, particularly in mathematics instruction at the junior high school level. A qualitative method was employed, combining a systematic review of relevant policy documents and journal articles with data obtained from virtual discussions involving mathematics teachers. The findings reveal that teachers require training that is practical, contextual, and grounded in classroom experiences, especially concerning differentiated instruction, formative assessment, and the integration of technology in learning. This study recommends the development of training programs tailored to teachers' actual needs and the strengthening of professional collaboration among educators to support continuous curriculum implementation.
