Abstract

This study addresses the lack of valid, practical, and easily accessible diagnostic assessment tools for identifying elementary school students’ learning difficulties, particularly in the topics of Least Common Multiple (LCM) and Greatest Common Divisor (GCD). The purpose of this study is to design and validate a mobile-based diagnostic assessment instrument suitable for fifth-grade students. This development research employed the 4D model. The study involved experts in mathematics education and digital media, a fifth-grade classroom teacher, and 30 elementary school students. Data were collected through expert validation sheets, diagnostic test items, and teacher and student response questionnaires. Quantitative descriptive analysis and qualitative interpretation were applied. Aiken’s V coefficient was used to measure content validity, while practicality was analyzed through the percentage scores of user responses. Students’ diagnostic results were further examined using item difficulty indices and error pattern analysis. The results indicate that the developed mobile diagnostic tool achieved very high validity (Aiken’s V > 0.80) and high practicality (>85%). However, the diagnostic findings reveal that students’ conceptual understanding remains low, particularly in distinguishing between multiples and factors. These results underscore the importance of enhancing item diversity and integrating adaptive feedback features. This study contributes to the development of digital diagnostic tools aligned with the Kurikulum Merdeka, supporting adaptive, data-driven, and technology-enhanced learning in elementary mathematics.

Abstract

An ideal assessment should offer constructive feedback and insights into students' strengths and weaknesses in learning. This study aims to develop an assessment model integrating formative assessment with Differentiated Instruction (DIFAM) to assess learning achievements proportionally. The DIFAM model was developed using the ADDIE development framework. The research sample consisted of 99 students from four high schools in Bandung Regency. Student learning profiles were analyzed using N-Gain and paired sample t-test. Data analysis was conducted with R Studio and JASP software. Data analysis using the N-Gain formula revealed an average improvement in student learning achievements of 25% with the implementation of DIFAM. The formative tests conducted over eight sessions showed that students grasped the material more effectively compared to conventional teaching methods. Feedback from students and teachers indicated that DIFAM facilitated more structured learning and provided constructive feedback, contributing significantly to enhanced student performance. The DIFAM model demonstrates its ability to cater to diverse student needs, achieve significant learning improvements, and has the potential for broader application to ensure more inclusive and equitable learning outcomes.
