{"abstract":"This study investigates the effect of an ethnoscience-based 7E’s learning approach on the communication and problem-solving skills of Grade 4 pupils at Surallah Central Elementary School. Using a true-experimental design, 60 students were divided into control and experimental groups. The experimental group used researcher-developed ethnoscience-based 7E instructional materials, while the control group used Learner’s Activity Sheets (LAS) provided by the Department of Education. Pre-test and post-test assessments were conducted to measure the targeted skills. The results revealed a statistically significant improvement in the communication and problem-solving skills of the experimental group compared to the control group, indicating the effectiveness of integrating local wisdom through inquiry-based models in science education.","abstract_source":"original","authors":["April Grace Diwatin","Susie Daza"],"date":"2025-05-15","doi":"10.70838/pemj.370704","id":5196,"issue":7,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"a40f401ba18ae9114d9affb602d171300271fe7427ae67ffac242ee163b00d3e","schema":"scimatic-article/1","title":"Ethnoscience-Based 7E’s Learning Approach: Effect on Pupils’ Communication and Problem-Solving Skills in Science","volume":37}
