The Effect of STEAM Project-Based Learning Approach Towards Student Learning Motivation: Utilization of Plastic Waste with Ecobricks Technique
AI summary Read the abstract
This study evaluated a STEAM-based Project-Based Learning model using ecobricks techniques to teach elementary students about plastic waste recycling, finding that it significantly improved student motivation, with posttest scores rising from 55.28 to 74.96 compared to pretest results.
The exponential increase in plastic production and the surge in plastic waste have led scientists and researchers to look for innovative and sustainable ways to recycle plastic waste to reduce its negative environmental impact. Project-Based Learning (PjBL) based on STEAM (Science, Technology, Engineering, and Mathematics) with ecobricks is one of the learning solutions for reducing plastic waste and increasing student motivation. This study aimed to determine the effect of the STEAM-based PjBL model with ecobricks techniques that can improve student learning motivation on ecology. This type of research is pre-experimental One-Group Pretest-Posttest Design. The sample in this study was 25 respondents. The sampling technique used by researchers was purposive sampling. The results of the study showed that based on the pretest in this study 55.28 after treatment was given to 25 respondents, the posttest results were 74.96. Other findings also showed a difference in the average value between the pretest and posttest. The sig. (2-tailed) value of 0.001 <0.05 then H0 is rejected and Ha is accepted, meaning that the steam-based project-based learning model is effective in increasing student learning motivation. Thus, STEAM-based PjBL with ecobricks techniques can improve the learning motivation of elementary school students. Keywords: PjBL, STEAM, ecobricks, learning motivation.

Teaching Strategies for Microplastic Material in Science Learning: Literature Review
AI summary Read the abstract
This Indonesian literature review analyzed science learning strategies for teaching microplastic environmental pollution topics, finding that Problem Based Learning and Guided Inquiry were the most frequently used and effective models for engaging students with this complex contemporary environmental issue. The review identified Discovery Learning as less commonly used for microplastics education due to the risk of student confusion without adequate guidance.
Using plastic pollution management worksheets in fundamental science class: An investigation on students’ sustainable awareness
AI summary Read the abstract
This study evaluated a practicum-based Plastic Pollution Management Worksheet intervention with 40 Indonesian university students, finding a moderate positive impact on sustainability awareness—with the largest gains in cognitive understanding and social engagement. Results suggest the worksheet approach shows promise as a pedagogical strategy but requires supplementation with other educational methods to achieve lasting behavioral changes toward sustainability.
Project-based Learning on Cassava Starch Bioplastic Production as an Instructional Model to Improve Scientific Literacy and Environmental Awareness in Junior High School Students
AI summary Read the abstract
Researchers taught teens to make bioplastics from cassava starch through hands-on projects, and test scores jumped from 70 to 89, showing students better understood plastic pollution and eco-friendly alternatives. Teaching kids practical science skills early could help build a generation more motivated to reduce plastic waste, the same plastic waste that breaks down into microplastics now found in human blood and organs.
