Abstract

This study aimed to determine the effect of the Student Teams Achievement Division (STAD) cooperative learning model assisted by the Quizizz application on fourth-grade students’ mathematical comprehension skills and cognitive learning outcomes in the topic of number patterns. This research employed a quantitative approach with a Matching Only Pretest–Posttest Control Group Design. The sample consisted of two classes: the experimental class, which received the STAD learning model supported by Quizizz, and the control class, which received conventional instruction. The research instruments included a mathematical comprehension test and a cognitive learning outcomes test that had been validated by experts. Data analysis included tests of normality, homogeneity, the Independent Sample t-test, and the calculation of N-Gain to measure the effectiveness of learning improvement. The results indicated that the post-test scores of the experimental class were significantly higher than those of the control class for both measured variables, with significance values of less than 0.05. The N-Gain results also showed that the improvement in mathematical comprehension and cognitive learning outcomes fell into the moderate category, indicating that the STAD model assisted by Quizizz was reasonably effective. It was concluded that the STAD cooperative learning model supported by the Quizizz application had a significant effect on improving students’ mathematical comprehension skills and cognitive learning outcomes. This model is considered feasible for implementation as an interactive and effective instructional strategy in elementary school mathematics learning.

Abstract

This study aims to develop Interactive Electronic Teaching Materials for the IPAS (Science and Social Studies) subject on the topic of Earthquake Disaster Preparedness based on Problem-Based Learning (PBL) to improve the critical thinking skills of fifth-grade elementary school students. The research background is driven by the geographical reality that Bengkulu is a region highly vulnerable to earthquakes, while existing teaching materials are print-based and do not cover earthquake preparedness in depth. This Research and Development (R&D) study employed the 4D model (define, design, development, and disseminate). The research subjects were one classroom teacher and 17 fifth-grade students at SD Islam Al Kiswah, Bengkulu City. Data were collected through observation, interviews, questionnaires, and essay-based critical thinking skills tests. The results showed that the developed interactive electronic teaching materials were valid (average validation scores: content and graphics = 0.889; language = 0.875), received positively by teachers and students (student positive response above 80% in all aspects), and effective in improving critical thinking skills (N-Gain Score = 0.71, high category). Therefore, these PBL-based interactive electronic teaching materials provide an innovative solution for fostering more meaningful and contextual IPAS learning .

Abstract

This study aims to develop a Discovery Learning-based Student Worksheet (LKPD) using Geoboard on the topic of plane figures area to improve cognitive learning outcomes of fifth-grade elementary school students. This research employed the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Research subjects consisted of 12 students and 1 teacher in the limited trial class, 28 students and 1 teacher in the control class, 28 students and 1 teacher in the experimental class, as well as 2 material validators, 2 language validators, and 2 design validators. Data were collected through interviews, questionnaires, and tests, then analyzed using qualitative and quantitative descriptive analysis. The results showed that: (1) material validity obtained an Aiken's V value of 0.85 (very valid) with inter-rater reliability of 83% (very strong); (2) language validity obtained 0.86 (very valid) with inter-rater reliability of 78% (strong); (3) design validity obtained 0.86 (very valid) with inter-rater reliability of 75% (strong); (4) user responses were very positive, with teacher response reaching 92% and student response 91%, both categorized as very good; and (5) the experimental class achieved an average N-Gain score of 0.66 (66%), categorized as effective, significantly higher than the control class which obtained 0.46 (46%), categorized as moderately effective, with a significant difference confirmed by independent sample t-test (sig. = 0.006 < 0.025). These findings indicate that the Discovery Learning-based LKPD using Geoboard is valid, practical, and effective in improving students' cognitive learning outcomes on the topic of plane figures area.

Abstract

This study aims to develop a Project Based Learning (PjBL)-based teaching module for Pancasila Education and to describe the profile of gotong royong character values among fifth-grade elementary school students. This research employed the Research and Development (R&D) method with the ADDIE model stages. Research subjects consisted of material, language, and design validators, as well as fifth-grade teachers and students of SD Negeri 141 Rejang Lebong. Data were collected through questionnaires, observation, and documentation, then analyzed using quantitative and qualitative descriptive analysis. The results showed that: (1) the developed module is characterized by project-based orientation, collaborative activities, contextual puzzle media, and integration of gotong royong character values covering collaboration, caring, and sharing aspects; (2) expert validation declared the module very feasible for use; (3) teacher and student responses were categorized as very positive; and (4) the profile of students' gotong royong character values showed very good results, with collaboration at 88%, caring at 93%, and sharing at 90%. These findings indicate that the PjBL-based teaching module is feasible as a learning tool for Pancasila Education and effective in fostering gotong royong character values among fifth-grade elementary school students.
