TEACHING THE TOPIC “ACID-BASE-pH-OXIDES-SALTS” IN GRADE 8 NATURAL SCIENCE USING THE 5E MODEL TO DEVELOP STUDENTS' SCIENTIFIC INQUIRY COMPETENCE

Abstract

This paper studies the application of the 5E model in teaching the topic “Acid, Base, pH, Oxide, Salt” in Natural Science subject for grade 8, with the aim of developing students’ Scientific Inquiry Competence. The study analyzed the relationship between the 5E model and the manifestations of Scientific Inquiry Competence, pointed out the requirements to be achieved in the topic “Acid, Base, pH, Oxide, Salt” suitable for teaching according to the 5E model, and described in detail the learning activities in each phase of this model, especially the discovery phase. In this phase, learning activities are suggested at different levels to suit the students. Two illustrative lesson plans on the topic “Acid, Base, pH, Oxide, Salt” were designed and pedagogical experiments were conducted with two classes at two secondary schools in Bac Ninh and Hai Duong, Vietnam. The results of the assessment of students' Scientific Inquiry Competence and learning outcomes after the experiment confirmed the feasibility and effectiveness of the proposed measures in the study.
