Abstract

Although students’ understanding of fraction concepts in elementary mathematics has received increasing scholarly attention, research specifically examining the use of manipulative media to improve conceptual understanding in rural primary school contexts remains limited. This study aims to evaluate the effectiveness of manipulative media in enhancing students’ understanding of fraction concepts at SDN 38 Bonto Perak, Pangkep Regency. A Classroom Action Research (CAR) design was employed, involving 20 students selected through purposive sampling. Data were collected through achievement tests, observation sheets, and documentation, and analyzed using descriptive quantitative techniques. The findings indicate that the use of manipulative media improved students’ conceptual understanding of fractions, as reflected in an increase in the average score from 62 in Cycle I to 82 in Cycle II and an improvement in learning mastery from 45% to 85%. These results suggest that manipulative media can facilitate hands-on and meaningful learning by helping students construct a clearer understanding of abstract fraction concepts. This study contributes to the literature on constructivist learning and elementary mathematics education by providing empirical evidence on the role of manipulative media in strengthening conceptual understanding. Practically, the findings imply that teachers should integrate manipulative media consistently into classroom instruction to enhance student engagement, conceptual comprehension, and mathematics learning outcomes.

Abstract

The Academic Attendance System (SIAKAD) is a crucial component in educational management at universities, aimed at facilitating the management of student attendance. This study aims to analyze student satisfaction with SIAKAD, focusing on user interface, available features, and its impact on the learning process. Data were collected through a survey involving 200 students from various programs and semesters, using a questionnaire designed to evaluate students' perceptions of the system. The results indicate that 75% of respondents access SIAKAD daily, with most spending 5-15 minutes each time. A majority of students (70%) find the user interface easy to use, although 30% of respondents indicated a need for improvements in navigation. The attendance and grade report features are the most frequently used, accessed by 85% and 70% of students, respectively. The impact of SIAKAD on the learning process is also significant, with 80% of respondents feeling that the system helps them manage attendance and enhance academic responsibility. This research is expected to provide useful insights for SIAKAD administrators in improving and developing the system in the future, as well as contribute to the literature on user satisfaction in higher education contexts. The findings also open opportunities for further studies on technology implementation in education and its effects on students' learning experiences.
