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.
