Engaging Teachers and Students in Problem-based Simulation Activities Abstract This study investigates the perceptions of teachers and students involved in problem- based simulation, (PBS) activities used in design engineering curricula to introduce simulation as a design tool to better evaluate design solutions. The presentation demonstrates a clear and concise interpretation of the teacher and students developmental perceptions of the curricula developed at Mott Community College through a grant from NSF to enhance existing design engineering curricula using PBS activities. Through this study it is evident that the PBS activities have enhanced the curricula by providing a tool for students to better understand design concepts. It is also evident, that teachers and students learned to value and trust using simulation software as a beneficial teaching and learning tool to evaluate and validate their own design solutions.
The criteria used to determine participant inclusion and sample size is based on the research primarily being a qualitative study in which a relatively small sample size of three school settings have been chosen to test the curriculum. Each of the three schools included at least two of their classes in the study teaching topics of gears, cams and threads in their design engineering classes. One class was a control group that received traditional methods of instruction and the other was the treatment group which participated in the PBS activities.
The study was conducted using a quasi-experimental post-test only design as a quantitative component, and a qualitative component comparing prior and post surveys and observations. The curriculum materials produced through the NSF grant are PBS activities related to topics of gears, cams and threads which provide problems for the students to solve using reference material, which they then verify using a CAD generated 3D model that simulates the solution to the problem. The output from the 3D simulation is in the form of a plotted curve on a graph providing the answer to the problem and also providing a 3D motion output for a virtual visualization of the problem.
Workshops are scheduled for May through July of 2006 to orient teachers how to utilize the design and simulation software used in the delivery of the PBS activities. After completing the workshops instructors possess the skills and curriculum to deliver summer recruitment camps or teach the topics of gears, cams and threads in their engineering technology classes using the 3D models of mechanisms and simulations.
Introduction Simulation of the dynamics of mechanisms used in engineering technology curricula is presently a new concept rarely studied and there is a lack of understanding of how such simulations can be used most effectively in engineering and in education. The following is a quasi-experimental action research study incorporating both quantitative and qualitative data. It investigates the perceptions of teachers and students involved in problem-based simulation activities used in high school design engineering curricula.
