Engineering design model: Environmental problem-solving ability, motivation and student perceptions

Abstract

This study aims to describe students'learning motivation, student perceptions and students' ability in designing problem solving of environmental pollution through learning of EDM. This is a descriptive study which involved 60 high school students in the West Bandung regency. Students were divided into two groups: EDM 1 and EDM 2. Students in EDM 1 are given the freedom to choose the tools and materials that will be used in making prototype while the students in EDM 2 are required to choose the tools and materials provided by the teacher. The results showed that students' ability in designing environmental problem solving through learning of Engineering Design Model (EDM) in EDM 1 and EDM 2 was not different (87.2% and 86,6%). Students in the EDM 1 class were superior to the ability to model prototype tools. While students in EDM 2 classes tended to be superior in the ability to identify problems. The result of student perception analysis showed that students in EDM 1 class had more motivation to innovate and had higher creativity than EDM 2 students.
