Abstract Micro-Electro-Mechanical-Systems (MEMS) are used as a vehicle to teach engineering and physical sciences concepts to high school students and to encourage more students to pursue careers in science and engineering. Drawing on a University research program in MEMS as a resource, the program guides students through the design process from solid modeling through manufacturing, and illustrates the applications of mathematics and physical sciences in engineering. A macro-scale (mm scale, rather than micrometer scale) analog to silicon micromachining that could inexpensively produce hand-held size planar layered structures will be used to illustrate the kinematics and geometry of MEMS devices. This analog will simulate the manufacturing process for MEMS without the need of a clean room or its highly volatile chemicals; it will use soap and wax, materials found in local hobby stores to produce macro scale models. The students will learn to use the program SolidWorks to create solid models of simple machines. They will translate their designs into kinematic models using a fused deposition of material rapid prototyping machine (Stratasys FDM1650) at the University, and also build soap and wax models that emulate lithography and micromachining at the K-12 school.
The project also includes an assessment portion to assess its effect on the students. At the beginning and end of the program, the students will fill out a questionnaire based on the Test of Science Related Attitudes (TOSRA). The test is designed to assess changes in student’s attitude toward scientific inquiry. An additional method of assessment, the review of students' comments in their personal portfolios, should indicate any overall change in attitudes about science and engineering. This program has the potential to be used as a model for schools to encourage students to pursue scientific or engineering careers.
A preliminary version of this program has been used at a private middle school (8th and 9th grade), and is being evaluated at a 9th-12th grade public high school.
