역공학 교육프로그램 개발을 통한 고등학교 기술과 공학교육 사례연구

Abstract

This study develops a reverse engineering education program and analyzes its implications in
 response to the emphasis on engineering in the revised 2022 high school Technology Education
 curriculum. To this end, the study examined the concept and model of reverse engineering as well
 as the technology curriculum. A reverse engineering education program was developed following the
 stages of hands-on activity development. To ensure the program’s completeness, expert validation
 and teacher feedback from case presentations at the A City Teachers' Association were incorporated
 to achieve both quantitative and qualitative improvements.
 Program practicality was assessed through a preliminary class conducted with 15 general high
 school students in City A over a period of four days in January 2024, consisting of 10 sessions.
 The meaning of the class was assessed through students' online portfolio materials, recorded class
 videos, and teacher reflection journals. The study’s results are as follows:
 First, reverse engineering offers students opportunities to learn product design principles,
 understand the functions of each component, discern the relationships between components, and
 identify areas for product improvement by dismantling a completed product. It affords students a
 concrete understanding of previously abstract engineering principles by working with actual products.
 Second, developed as a 10-session program following the stages of preparation, development, and
 improvement, the program was applied to 15 general high school students in City A during a
 four-day preliminary class, and the resulting data informed final modifications and completion of the
 education program. Third, student experiences were analyzed through themes such as understanding
 engineering principles through participation, experiences of failure and challenges, sense of
 accomplishment in product operation, interest in engineering, and career exploration.
 This study provides insights into implementing the engineering education emphasized in the
 revised 2022 technical and vocational curriculum in school settings. The results have implications
 for the technology education field and future curriculum revisions.
