information about the process of research. Many of the ideasand plans in place or in progress at the nation’s research institutions are based on ideas laid out inthe Boyer Commission report [6] that highlights an integrated education through undergraduateresearch opportunities.Many of the larger public research schools struggle with low retention rates in STEM. Forinstance, at Washington State University freshman to senior retention in engineering is 48%. Asnoted in the literature [7], many STEM fields use undergraduate research as a capstoneexperience, held until the end of the curriculum as a culminating experience. However, it has Page

pressure on the instructor. No longer can theinstructor come to class with a clear, well-defined script for the day’s lecture. Instead, theinstructor finds himself metaphorically “negotiating a swiftly flowing river” in class.15 Thisrequires agile teaching and the flexibility to deal with the unexpected, which is perhaps outsidesome instructors’ comfort zones, particularly for novices or those not confident of the subjectmatter.3 Additionally, it encourages the instructor to give thought beforehand to possible studentmisconceptions and alternative routes for constructing correct understandings, so that on-the-flyadjustments may be more effective. Also, the insights gained by the formative assessment canbe useful for planning subsequent class

Thereason for this low rating is unknown, but, in any case, only a very small minority of the studentsfelt this way.Planned Future WorkThree of the four described experiments (i. e., the electric circuit, the cooling of a cylinder, andthe cantilever beam experiments) are portable and can be moved via carts into the computer lab.Plans are to make a small-scale, portable version of the orifice flow meter experiment that canalso be transported into the computer lab.

Nowadays, computer applicationsare not limited to proprietary software because a range of free, open source applications areavailable online that students can download and learn to use on their own. This type of learningempowers students with specific skills that cannot be acquired through formal academiclearning. Students become more self-directed in their learning when they take the primaryinitiative for planning, carrying out, and evaluating their own learning experiences 9. Theyassume ownership for their own thoughts and actions leading to the notion of “personalresponsibility in learning” 24.
