Research in preparing and supporting faculty as they transition pedagogical paradigmsinto those that engage and cultivate students in an active learning environment is of current needand will grow as more active learning spaces are designed and built.The faculty development program was a deliberate collaboration bringing together the expertiseof three campus units - the College of Engineering, the Center for Teaching Excellence, andInstructional Technology Services. Titled the Active Learning in Engineering Program (ALEP),the researchers created a comprehensive faculty development program that consisted of fivemain components: (a) a learning management system online community, (b) a workshop series,(c) community of scholar’s

A key feature of the venturi LC-DLM is the changing diameters. We were interestedin how participants’ ability to see the changing diameters in the venturi LC-DLMs helped themunderstand key concepts about velocity changes, energy transformations and pressure changes.Appendix B shows the descriptive statistics of participant responses on three items about thechanging diameters.

Empathetic Resonance - Person A experiences a shared emotional state related to the topic of conversation with Person B 3. Expressed Empathy - Person A expresses their resonance from step 2 to Person B 4. Received Empathy - Person B confirms that Person A has indeed experienced the same emotional state and that they feel understood on an emotional levelKouprie and Visser [3] proposed a framework for incorporating empathy into design.

An importantlesson learned from the first time offering of this project was the need to have a bettersupervision over the teams’ workflow and create an environment for a better and moretransparent team communication. Since most groups consisted of members located on differentcampuses, there were occasions that the team members were completely blindsided on theprogress of the project by the other members.

rope), but moment is a relatively abstract concept to them.Additional frustration is encountered due to the term "moment" since it conflicts with thestudents' prior knowledge from their physics course. There, they encountered the concept ofmomentum. This prior knowledge often leads to two misconceptions: 1. Since momentum is formed from the root "moment" with the addition of a derivational morpheme (-um), students assume that the concept of momentum presented in Physics is the same as the concept of moment in Physics. 2. The term moment has different meanings: (a) brief period of time, or (b) effect produced by a force acting at a distance on an object. Since "moment" is homographic and students have

Likely reasons for this is the cost to purchase, maintain, and upgrade experimentalapparatus; facilities requirements that can include compressed air and/or hydraulics in addition toelectric power; and the lab space to house the traditional control system equipment, which canhave a fairly sizable footprint. Given the low demand, there are a limited number of vendors whosell control system lab equipment and, hence, the range of apparatus that is available is alsolimited
