Abstract

This project seeks to improve sixth-graders' mathematics communication abilities and find ways to teach prisms and pyramids at State Elementary School 060912. Classroom Action Research (CAR) was used. The subjects were 27 sixth-graders. The Think-Talk-Write learning technique was used to improve students' mathematics communication skills. Tests and observation were employed in this investigation. Both cycles of this study ended with a mathematics communication skills test. A validator checked the test before administering it. The first cycle survey found that 77.78% of pupils understood writing (moderate), 59.26% understood representation (poor), and 74.07% acquired classical mastery (adequate). The second cycle showed that 88.89% of pupils understood writing, 85.19% understood representation, and 88.89% reached classical mastery. Observers rated the researcher's learning management as good in the first cycle (83.33 points) and good in the second cycle (88.89 points). Learning through the TTW strategy, media additions, more extensive problem-solving procedures in the LAS than in the first cycle, and group size decrease to 3-4 students improved mathematics communication abilities.  According to the above description, the Think-Talk-Write learning technique can improve sixth-grade students' mathematical communication skills when teaching prisms and pyramids at State Elementary School 060912.

Abstract

This study aims to improve students’ learning outcomes through the Picture and Picture learning model integrated with the Wordwall application in the IPAS subject for fourth-grade students. The research employed a quantitative approach with a pre-experimental design (one-group pretest–posttest design). The sample consisted of all 28 students in Class IVA at SD Negeri 101740 Tanjung Selamat, comprising 9 male and 19 female students. Data were collected using learning achievement tests administered before and after the intervention, as well as observation and documentation techniques. The collected data were then analyzed quantitatively. The findings indicate that the use of Wordwall significantly improved students’ learning outcomes, as evidenced by the increase in mean scores from the pretest to the posttest. This improvement reflects a higher level of understanding of the instructional material. Furthermore, the integration of the Picture and Picture model with Wordwall was effective and engaging, fostering interactive learning through visual representations and digital quiz activities. Students demonstrated greater participation, focus, and enthusiasm during lessons. In addition to enhancing conceptual understanding, the model also supported the development of students’ critical thinking and collaborative skills. In conclusion, the Picture and Picture model supported by the Wordwall application can serve as an effective alternative instructional strategy for improving students’ learning outcomes.

Abstract

Low awareness regarding Clean and Healthy Living Behavior (PHBS) among early childhood students in the post-pandemic era presents a serious challenge for the partner institution. This multidisciplinary service and research initiative integrates Education (kinesthetic learning methods), Communication (visual campaigns and interpersonal persuasion), and Accounting (financial literacy education and healthy budget accountability) at the Permata Jaya Kindergarten and Early Childhood Education Center (TK KB) in 2026. Key issues faced by the partner included children's lack of independent hygiene practices, monotonous health communication, and the absence of a dedicated budget allocation for school sanitation. Implementation methods involved interactive storytelling, the creation of PHBS visual aids, and guidance on preparing a petty cash budget for sanitation needs. Results demonstrated a dramatic 85% increase in children's understanding of PHBS, a 90% improvement in the effectiveness of health messaging, and the establishment of transparent financial reporting for school sanitation. This multidisciplinary collaboration proved effective in fostering healthy habits among children while simultaneously strengthening the governance of school health facilities.
