Abstract

This research is motivated by the limited use of interesting and interactive digital learning media in science learning in grade V of Nan Sabaris Elementary School, thus impacting the effectiveness of the learning process and student learning outcomes. This study aims to develop an E-Book media based on the Book Creator application that is valid, practical, and effective for use in science learning. This research is a research and development (R&D) with stages of analysis, design, development, and evaluation. The results of the validity test showed a score of 85.00 for material experts, 90.00 for language experts, and 97.50 for media experts, all of which are in the very valid category. The practicality test by grade V teachers at SDN 17, SDN 15, and SDN 16 Nan Sabaris obtained an average score of 99.16% with a very practical category, while student responses showed very good results. The effectiveness test based on the N-Gain analysis showed values of 0.7694, 0.8000, and 0.7692 with a high category. Thus, Book Creator-based E-Books are suitable and effective for use in science learning in elementary schools.

Abstract

Puberty is a critical developmental phase characterized by biological, psychological, and social changes that influence students' character development. During this period, curiosity and discipline often undergo significant changes that affect learning behavior. This study aimed to explore changes in students' curiosity and discipline during puberty at MIS Bakti, Padang City, and to examine the roles of teachers, parents, and peers in shaping these character changes. A qualitative case study approach was employed involving two students in the puberty phase as the primary participants, supported by teachers and parents as key informants. Data were collected through classroom observations, in-depth interviews, and documentation, and analyzed using data reduction, data display, and conclusion drawing with verification. The findings revealed that both students experienced a shift in curiosity from academic learning toward social and emotional interests, particularly curiosity related to interpersonal relationships. This shift was accompanied by declining discipline, reflected in reduced learning focus, violations of school dress regulations, and decreased compliance with school rules. The findings also showed that teachers, parental guidance, and peer interactions played decisive roles in either supporting or hindering the development of students' curiosity and discipline during puberty. The study concludes that effective character development during puberty requires consistent collaboration among schools, families, and peers to channel students' curiosity into positive learning experiences while strengthening discipline.
