A Problem-Solving Approach in Practical Topic Research The Design of A
[Chemical-Energy-Car]
Abstract
The purpose of this study was to understand the creativity creative design and the
process and ability of problem-solving in the process of manufacturing a Chemical Energy
Car as a practical topic research. A problem-solving approach method was used in data
collection and analysis, and anecdote records observation records by teacher
experimental records oral report and result of the works of the authentic performance
evaluation was used to understand creativity creative design and problem-solving process
and ability of students. They designed a special chemical energy car by themselves with
cooperative learning, and they also solved problems of the car body transmission system
chemical energy and stopping in the setting distance with loading. Obviously, the practical
subject in the course of topic research can make students learn more with cooperative
learning, and help them to solve the practical problem which they will meet in the future.
Keywords: Chemical Energy Car problem-solving authentic performance evaluation
topic research.
