Abstract

Purpose – This study aims to investigate the effect of a Problem-Based Learning (PBL) model grounded in the local wisdom of Simalungun Marharoan Bolon on the Natural Science learning outcomes of fourth-grade students at UPTD SD Negeri 094155 Rambung Merah. The study is motivated by the need to integrate culturally relevant approaches to improve elementary science achievement. Methodology – The research employed a pre-experimental method using a One-Group Pretest–Posttest Design. The population comprised all fourth-grade students, with a purposive sample of 28 students selected based on class availability and feasibility. The intervention consisted of implementing the Marharoan Bolon-based PBL model during science instruction. Research instruments were tested for validity, reliability, item difficulty, and discriminating power. Data analysis included normality testing, paired sample t-test, and N-Gain analysis to determine learning improvement. Findings – The results indicate a significant improvement in students’ learning outcomes after the intervention. Statistical analysis showed t_count = 15.29, which exceeded t_table = 2.052, with a significance value of 0.00 < 0.05. These findings confirm that the Marharoan Bolon-based PBL model had a significant positive effect on students’ science achievement. Novelty – This study integrates a modern instructional model (PBL) with indigenous local wisdom, demonstrating the effectiveness of culturally responsive pedagogy in elementary science education. Significance – The findings benefit elementary teachers, curriculum developers, and education policymakers seeking culturally grounded strategies to enhance science learning outcomes.

Abstract

Purpose – This study aims to examine the effect of the Problem-Based Learning (PBL) model on the creative thinking skills of fourth-grade students in Natural and Social Sciences (IPAS) at SD Negeri 091608 Sinaksak. The research was motivated by students’ low creative thinking ability due to teacher-centered instruction and limited active participation. Methodology – A pre-experimental design using a one-group pretest–posttest approach was employed. The sample consisted of 23 fourth-grade students (12 boys and 11 girls). Data were collected through pretest and posttest instruments measuring creative thinking skills. Instrument validity and reliability were tested, and data were analyzed using the N-Gain test to determine the level of improvement after the PBL intervention. Findings – The results indicate a significant improvement in students’ creative thinking skills following the implementation of PBL. The average score increased from 50.22 (pretest) to 83.86 (posttest). Initially, most students did not achieve mastery, whereas after the intervention almost all students met the learning criteria. N-Gain scores ranged from 0.56 to 1.00, indicating moderate to high improvement. These findings suggest that PBL effectively enhances creative thinking in IPAS learning. Novelty – This study provides empirical evidence of the effectiveness of PBL in improving elementary students’ creative thinking skills within the integrated IPAS subject context. Significance – The findings benefit teachers, school administrators, and curriculum developers seeking effective student-centered learning strategies to foster creativity in primary education.

Abstract

This study aims to develop a digital flipbook-based learning media on regional economic conditions and determine its feasibility for fifth-grade elementary students. The research was motivated by low student learning interest and the limited use of digital media in IPAS learning. This study employed a Research and Development (R&D) method using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The data were collected through expert validation questionnaires (material, language, and media experts) and responses from teachers and students, analyzed using a Likert scale. The results showed that the developed flipbook media was categorized as very feasible, with material expert validation at 93%, language expert at 91%, and media expert at approximately 93%. Teacher responses reached 92% and student responses 89%, both categorized as very feasible. Therefore, the digital flipbook learning media is suitable as an alternative learning tool in elementary schools.

Abstract

Pembelajaran di Sekolah Dasar saat ini masih didominasi metode konvensional berpusat pada guru yang kurang mengaitkan materi dengan kehidupan nyata. Kondisi ini menyebabkan rendahnya keterlibatan aktif dan kemampuan berpikir kreatif siswa sebagai kompetensi abad ke-21. Selain itu, mitra guru menghadapi kendala berupa keterbatasan pemahaman terhadap konsep Contextual Teaching and Learning (CTL), kurangnya variasi strategi, serta ketiadaan perangkat pembelajaran sistematis. Pengabdian kepada Masyarakat (PkM) ini bertujuan mensosialisasikan model CTL guna meningkatkan kemampuan berpikir kreatif siswa dan kompetensi guru dalam mengembangkan perangkat pembelajaran inovatif. Metode pelaksanaan meliputi koordinasi analisis kebutuhan, sosialisasi konsep, pendampingan penyusunan Modul Ajar, praktik simulasi kelas, serta evaluasi bersama pihak sekolah. Target luaran meliputi peningkatan pemahaman guru, tersedianya Modul Ajar berbasis CTL yang aplikatif, dan publikasi artikel ilmiah pada jurnal pengabdian masyarakat. Sosialisasi model CTL menjadi solusi strategis dalam meningkatkan kapasitas profesional guru untuk menciptakan suasana belajar yang bermakna. Implementasi CTL diharapkan mampu meningkatkan kualitas pendidikan dasar dan menstimulasi potensi berpikir kreatif siswa secara optimal guna menghadapi tantangan perkembangan zaman. Dengan demikian, kegiatan ini memberikan dampak positif signifikan bagi pengembangan kompetensi pendidik dan peserta didik di sekolah dasar mitra secara luas serta berkelanjutan melalui integrasi kolaborasi akademik yang kuat.
