Learning of Objects, Elements, Compounds, and Mixtures in Daily Life’s Elementary School Students

Abstract

This study aims to grow elementary school students' knowledge of objects, elements, compounds, and mixtures that exist in everyday life. The learning approach used is scientific learning using two methods and two learning models. The first learning model is discovery-based learning with PowerPoint’s lecture learning method. The second learning model is project-based learning with a practicum learning model. Students were given 14 pretest questions before learning and 14 posttest questions after learning. This study was conducted on 36 elementary school students in Bandung, Indonesia. This study indicates that students can identify objects, elements, compounds, and mixtures that exist in everyday life. This is evidenced by the increase in the class average score from the pretest and posttest results of 35.11%. Learning is done using interactive PowerPoint so that students can participate more actively. In addition, practical assignments for students also make students better understand and remember the material that has been taught. Learning objects, elements, compounds, and mixtures using discovery-based and project-based learning models shows good results.
