Abstract
This study aims to develop and verify instructional effects of coordinated problem-solving performance tasks in consumer education on junior high school home economics. Performance tasks were developed using a knowledge-based constructive jigsaw method involving role- plays wherein a group of four students engage in family planning to purchase home appliances. Analysis of classroom implementation indicated that students could resolve issues by utilizing the acquired knowledge and skills, leading to deeper understanding and actual empathy. Students also contributed to the family’s purchase plan. Thus, these tasks proved effective in consumers’ decision- making process.
