. Figure 1: diagram (A) and photo (B) of the holography apparatus.After successfully teaching this lab for the first time, we wanted to further investigate thesystem’s sensitivity to torsions and rotations. A few different experiments were tried and aresummarized here. First, as shown in the middle panel of Figure 2, we introduced only a verticalrotation of the metal beam by clamping it in the middle and applying a point load to the end.Rotation is not something a strain gauge can sense, since it uses the deformation of a metal foilto generate its signal (namely, a changed electrical resistance). In this setup, the small rotation isreadily determined, and produces evenly spaced and perfectly vertical fringes. With 4 fringesacross the 10 mm of beam

In this paper, quantitative andqualitative data collected over the past three years was analyzed collectively, triangulated, and related torelevant research and theories. This process allowed us to work toward: (1) providing a more generalizabledescription of our overall findings, (2) gaining a greater understanding of the underlying classroom and coursefactors and their impact on the development of domain-specific efficacy among minority students, and (3)developing a set of guidelines to effectively incorporate participatory design based on the situated learningframework.

We also measuredthe number of steps students took to complete the game between the two game versions, shown inFigure 5(b).
