The results from all three schools were compiled andanalyzed by the collaborator at VCU and an expert from the Education Department at VCU. Theresults were then communicated with the other two collaborators to further refine thecomponents for the next development and implementation phase.The Expected Learning OutcomesAfter being exposed to the piezoactuator module, students should be able to: (a) understand thefundamental concepts of modeling and control of piezoactuators, (b) transfer the knowledge tosolve engineering problems at higher levels of abstraction, (c) recognize mechanical

The iLab Batched architecture is referred to as “iLab-B” in this paper todistinguish it from the iLab Interactive architecture. The iLab-B architecture separates thevarious parts of a VL in such a way that only a very small amount of data needed to configurethe remote system under test needs to go through the low-bandwidth uplink, while all other datalab-related activities are done locally. As a result, the MIT iLab-B architecture was an idealplatform upon which to base the development of a new Operational Amplifier virtual laboratory(“OpAmp Lab”) hosted at Obafemi Awolowo University, Nigeria.II.
