Abstract

This paper reports the results of course restructuring employing design projects in an introductory mechanics of materials course at Pennsylvania State University. Unlike traditional lecture courses, students were encouraged to learn the rudiments of mechanical design and how materials standards, economics, manufacturing, environmental, legal (liability) and societal (safety) concerns relate to design. Through conducting collaborative design projects, the instructors helped students to acquire more advanced skills such as team-based decision making, integration and establishment of criteria, use of modern design theory, consideration of alternative solutions, and application of realistic constraints. In order to examine the impact of new course changes on students' learning, a survey was conducted in 1998 Fall semester. According to the results of survey analyses, students reported high values on this introductory mechanics of materials course. However, they did not give high values on the design projects. Rather, they preferred lecture sessions. Additionally, it was also found that students who earned higher grades from a prerequisite course(statics) showed lower values on the design projects. Implications for engineering educators and suggestions for future research studies were discussed.

이 논문은 펜실베니아 주립대학에서 실시된 수업개선에 관한 것으로 그 내용은 디자인 프로젝트를 재료역학 수업에 응용한 결과이다. 전통적인 강의를 활용한 수업과는 달리 학생들은 기계역학 디자인의 기초와 재료, 표준, 경제적인 요소, 제작상의 특성, 환경문제, 법 및 안전과 관련된 제반 문제들 등이 서로 연관되어 있음을 학습하도록 격려되었다. 협동학습 디자인 프로젝트를 통해 강사들은 학생들이 팀 단위의 의사결정, 평가기준의 설정과 통합, 현실적인 대안의 발견, 현실적인 제한점들에 대한 고려 등의 보다 고차원적인 내용을 학습할 수 있도록 도왔다. 새로운 수업개선이 학생들의 학습에 미친 영향을 알아보기 위해 1998년 가을학기에 설문조사를 실시하였다. 이 설문조사 결과에 따르면 학생들은 재료역학 입문수업에 대해 높은 가치를 부여하였다. 그러나 디자인 프로젝트에 대한 가치점수는 낮게 나타났고 오히려 전통적인 강의에 높은 가치를 부여했다. 더불어 이전 선수과목에서 높은 점수를 받았던 학생들이 디자인 프로젝트에 대해 낮은 가치를 보고했다. 공학교육자들을 위한 시사점과 향후 연구과제에 대한 제
