Abstract

Persistent challenges in elementary science education, including teacher-centered pedagogy, low student engagement, and inadequate learning outcomes, necessitate pedagogical innovations that promote active participation and conceptual understanding. This classroom action research investigated the effectiveness of the Numbered Heads Together (NHT) cooperative learning model in enhancing fourth-grade students' learning outcomes in Science and Social Studies (IPAS) at SD Inpres Perumnas Palu. Twenty-eight students participated in two iterative cycles comprising planning, implementation, observation, and reflection phases. Data were collected through achievement tests, structured observation sheets for teacher and student activities, and field documentation, analyzed using both quantitative and qualitative methods. Findings demonstrated progressive improvements across all measured variables. Teacher activity increased from good (68-73%) in Cycle I to very good (92-95%) in Cycle II. Student engagement advanced from adequate (61-63%) to very good (80-81%). Most significantly, classical mastery rose from 33% at baseline to 43% in Cycle I and 79% in Cycle II, surpassing the 65% success criterion. Results confirm that NHT effectively transforms passive learning environments into active collaborative spaces, supporting both cognitive achievement and social-emotional development. The structured accountability mechanisms inherent in NHT promote equitable participation and peer-mediated learning consistent with social constructivist principles, demonstrating applicability in resource-limited settings with diverse student populations.

Abstract

Despite progressive curriculum reforms emphasizing student-centered learning in Indonesia's Kurikulum Merdeka, elementary IPAS instruction remains predominantly teacher-centered, limiting student engagement and conceptual understanding. This classroom action research employed Kemmis and McTaggart's cyclical model across two intervention cycles with 28 Grade IV students at SD Inpres Perumnas Palu. Data were collected through achievement tests, structured observations of teacher and student activities, and field documentation. Analysis integrated quantitative measures of learning mastery with qualitative assessment of instructional processes using Miles and Huberman's framework. Classical mastery remained stable between pre-action baseline (28.57%) and Cycle I (28.57%), indicating that procedural implementation alone proved insufficient. Following targeted refinements in Cycle II—including enhanced scaffolding, systematic group monitoring, and explicit instructional guidance—classical mastery increased dramatically to 85.71%, surpassing the 80% success criterion. Student activity improved from 58% to 69.5%, while teacher activity increased from 55% to 68%. Findings demonstrate that Jigsaw cooperative learning effectiveness depends critically on implementation quality rather than structural arrangements alone. Results align with constructivist and sociocultural learning theories, particularly Vygotsky's Zone of Proximal Development, confirming that appropriately scaffolded peer interaction enables students to achieve understanding beyond independent capabilities. The study extends predominantly Western cooperative learning scholarship into Indonesian elementary contexts, providing empirical evidence for pedagogically thoughtful implementation strategies.

Abstract

Traditional teacher-centered instruction in Indonesian elementary schools limits student engagement and conceptual understanding, particularly in integrated science curricula. This study investigated the effectiveness of Student Teams Achievement Division (STAD) cooperative learning in improving IPAS (Natural and Social Sciences) learning outcomes among fifth-grade students. Employing classroom action research design, this study implemented STAD across two iterative cycles with 32 fifth-grade students at SD Inpres Perumnas Palu during the 2025/2026 academic year. Data were collected through achievement tests, structured classroom observations, and teacher interviews. Quantitative analysis measured individual and classical mastery rates, while qualitative analysis using the Miles and Huberman framework examined engagement patterns and implementation quality. Classical mastery increased substantially from 19% at baseline to 40% in Cycle I and 87% in Cycle II, exceeding the 80% success criterion. Mean achievement scores rose 65% from 49.29 to 81.15. Student engagement improved from 70% to 86%, while teacher implementation quality increased from 75% to 83%. Heterogeneous grouping facilitated effective peer scaffolding, with proportionally greater gains among initially lower-performing students. STAD effectively enhances both academic achievement and student engagement in integrated science instruction. The study demonstrates that structured cooperative learning, supported by reflective practice and iterative refinement, operationalizes constructivist principles and supports holistic student development in resource-constrained educational contexts.

Abstract

Elementary students in IPAS (Integrated Science and Social Studies) often struggle with abstract concepts requiring visual representation and collaborative reasoning. The Picture and Picture cooperative learning model offers a pedagogical approach integrating visual scaffolding with structured group activities. This study examined the effectiveness of the Picture and Picture model in improving Grade V students' learning activities and outcomes in IPAS instruction at SD GKST Talabosa, Indonesia. A two-cycle Classroom Action Research design was employed with 12 fifth-grade students during the 2025/2026 academic year. Data were collected through achievement tests, structured observations of teacher and student activities, and field notes. Analysis combined quantitative measures of mastery levels with qualitative examination of instructional processes. Student engagement increased from adequate (69.23%-72.30%) in Cycle I to very good (81.53%-86.15%) in Cycle II. Teacher performance improved from good (68.42%-75.00%) to very good (76.00%-85.33%). Classical mastery advanced dramatically from 25% at baseline to 66.66% in Cycle I and 100% in Cycle II. Lower-achieving students demonstrated the greatest gains. The Picture and Picture model effectively enhances IPAS learning by combining dual-coding theory, constructivist principles, and social interdependence. The model provides an accessible, low-cost strategy particularly effective in resource-constrained settings, supporting both cognitive development and collaborative competence in elementary science education.
