A Project-Based Approach to DOE in Materials Lawrence J. Genalo Iowa State University

1. Introduction

At Iowa State University, the Materials Science and Engineering Department teaches a course in the statistics of materials. Approximately one third of this two credit course is devoted to the design of experiments (DOE). A relatively brief introduction to the theory of DOE sets the stage for the inclusion of a software package used to assist materials engineers to design and analyze the results of experiments.

Texts for engineering statistics (1-3) contain chapters dealing with the design of experiments. Literature in materials journals routinely contains references to DOE (4-8). Coupling these texts and recent articles with some practical exposure to design of experiments and the software used to do this, allows students some exposure to industrial practice. In this course students are assigned a major project (20 % of the grade) to be performed in teams. In this project students are encouraged to draw from their co-op and internship experiences. They are also asked to consider to expand upon experiments encountered in other courses in the curriculum.

2. Desired Learning Outcomes

Some of the learning objectives for this course are for students to be able to… 1. Choose control variable settings to design experiments that improve the likelihood of finding statistically significant results which improve the performance of a material or system. 2. Conduct experiments, gather data, analyze data, and report on the experiment. 3. Present oral and written reports on an experiment designed, run, and analyzed by teams of students. 4. Function in teams.

These objectives are being met through the use of a project-based approach to learning design of experiments (DOE). The project, which counts for 20 % of the student’s grade, is performed in teams of 3 or 4 students. Students are required to choose a materials-related, multi-factor experiment and then design, run, and analyze the results of this experiment. They submit a brief project proposal and then report on the results through a 10 minute oral presentation and a 10 page paper. They are encouraged to choose topics from their industrial or national lab co-ops and internships. Those students who haven’t had such experiences yet (97 % of our graduates do), are encouraged to partner with others who have or choose a topic related to another materials course they
