This paper presents work-in-progress in terms of a framework that we have structured to support effective joint development among faculty from different engineering backgrounds, spanning mechanical engineering (ME), electrical engineering (EE), and materials engineering (MatE). The framework is organized in short instructional modules designed to span not only major device types and different fabrication technologies, but also different levels of resource requirements. An example of using functional prerequisites--rather than course prerequisites—is presented for one module, wherein each functional prerequisite must be satisfied by at least one member of each student team that will undertake the module. Roles of the faculty course designers are arranged to manage the complementary and essential aspects of design, fabrication, and testing. Each of these is essential to hands-on learning. As the work is still in progress, we do not present a formal set of conclusions, but do close with our observations on how these elements have served the module development process midstream.
