The journal publishes original research articles in the field of mathematics education and is issued biannually (April and October). JIPM focuses on the dissemination of innovative research related to mathematics teaching and learning, including instructional strategies, curriculum development, educational technology, teacher education, and contemporary issues such as numeracy literacy and ethnomathematics. The journal accepts various research approaches, including experimental studies, research and development (R&amp;D), classroom action research, survey research, and mixed methods. By promoting evidence-based practices and academic collaboration, JIPM contributes to the advancement of mathematics education at national and international levels.</p> en-US ernipuji@umpwr.ac.id (Dr. Erni Puji Astuti, M.Pd.) riawanyudi@umpwr.ac.id (Riawan Yudi Purwoko) Tue, 19 May 2026 10:01:54 +0700 OJS 3.1.2.2 http://blogs.law.harvard.edu/tech/rss 60 https://jurnal.umpwr.ac.id/jipm/article/view/6766 <p>This study aims to examine students’ mathematical creative thinking skills and the factors influencing their ability to solve multicultural-based open-ended problems. Data were collected through three open-ended mathematical creative thinking test items and interviews with the participants. The data analysis process was conducted through the stages of data reduction, data presentation, and conclusion drawing. The results showed that the mathematical creative thinking skills of the first subject (S1) and the third subject (S3) were categorized as creative, while the second subject (S2) was categorized as less creative. Subjects S1 and S3 successfully fulfilled all indicators of creative thinking, namely fluency, flexibility, originality, and elaboration, whereas subject S2 only fulfilled the indicators of fluency and elaboration.</p> Azizatun Nafi'ah, Arezqi Tunggal Asmana, Abdur Rohim Copyright (c) 2026 Jurnal Inovasi Pendidikan Matematika (JIPM) https://jurnal.umpwr.ac.id/jipm/article/view/6766 Thu, 30 Apr 2026 00:00:00 +0700 https://jurnal.umpwr.ac.id/jipm/article/view/7414 <p>This study aims to determine the validity, practicality, and effectiveness of learning media developed in the form of Digital Student Worksheets (LKPD). This Research and Development (R&amp;D) study was conducted to produce digital worksheets that can support and improve students’ mathematics learning. The development model employed in this study was ADDIE, consisting of five stages: Analyze, Design, Development, Implementation, and Evaluation. The research subjects consisted of 27 junior high school students and one teacher, including 10 students in a small-scale trial and 17 students in a large-scale trial. The object of the study was the designed Digital LKPD. Data were collected through questionnaires, observations, and assessment tests. The data analysis techniques included: (1) product validity analysis, (2) product practicality analysis, and (3) product effectiveness analysis. The validation results from experts indicated that the developed Digital LKPD met the criteria of being highly valid. In addition, the results of student and teacher response questionnaires showed positive responses with percentages of 80% and 78%, respectively. The effectiveness test also demonstrated satisfactory student learning outcomes with an average percentage of 88.23%. Therefore, it can be concluded that the Digital LKPD developed for mathematics learning is valid, practical, and effective for use in the learning process.</p> Kurniawati Sri Rianti Wahyuningsih Petta Solong, Heny Sri Astutik, Mukhlas Triono Copyright (c) 2026 Jurnal Inovasi Pendidikan Matematika (JIPM) https://jurnal.umpwr.ac.id/jipm/article/view/7414 Tue, 19 May 2026 10:01:26 +0700
