Abstract

The purpose of this study was to construct a learning framework for trade-off that is an essential concept of technology. We also examined a practical teaching method that applied the framework in a technology education class. Trade-off in technology education is defined as the focus on some objective elements and specifications to those related to social, environmental, and economic viewpoints in learning design. The framework was constructed using the following elements: “understanding task and configuration,” ”planning and design in limiting conditions,” “planning and design under an additional condition,” and “practice and evaluation.” A practical teaching method was formed using the teaching material, “TECH-mirai.” The lesson plan about “technology of energy conversion” was investigated for 142 eighth grade students. The students were evaluated based on descriptions of their learning activity; furthermore, we found that more than 80% of the students were thinking and making judgments from social, environmental, and, economical viewpoints. About 30% of the students clearly described the trade-off that was made. Key words: Technology education, Trade-off, Teaching method, TECH-mirai teaching material
