Abstract

Mathematical creative thinking ability refers to a student’s capacity to solve problems, integrate existing knowledge and skills, and generate new ideas based on key concepts. However, observations in the field indicate that students’ mathematical creative thinking abilities remain relatively low. This study aims to determine the effectiveness of a Problem-Based Learning (PBL)-based Electronic Student Worksheet (E-Worksheet) in improving elementary school students’ mathematical creative thinking, supported by an Android application called Bangun Ruang Sisi Datar (Bangsidat). The PBL model, assisted by the Bangsidat Android application, is designed to enhance students’ creative mathematical thinking skills. Thus, the primary objective of this research is to develop an Android-based student worksheet that supports this goal. The method used in this study is Design Research, which consists of two main stages: planning design and formative evaluation design. The research subjects were 28 eighth-grade students from SMP Negeri 2 Haurgeulis, located in the Haurgeulis Subdistrict of Indramayu Regency. Data collection instruments included attitude scales, interviews, documentation, and problem-solving tests. The collected data were analyzed using both quantitative and qualitative methods. Based on the results, the average score of students’ mathematical creative thinking across all questions was 80.81%, falling into the "very effective" category. The highest score was recorded on question number 2 with 86.50%, while the lowest was on question number 4 with 74.50%. The conclusion of this research is that the PBL-based E-Worksheet, supported by the Bangsidat application, is highly valid, practical, and effective in enhancing students’ creative.
