The first session, during the summer of2012, consisted of three days of hands-on instruction. At the end of the first session, the teacherswere given an assignment to complete during the fall semester. The second workshop sessionconsisted of a 1-day meeting in December 2012, during which the teachers presented completedassignments and participated in a group discussion. Sixteen high-school teachers participated inthe program. Participants received 20 hours of professional development credit. Meals wereprovided along with a $100 daily

APSC-100 is a team-based, project-basedcourse designed to promote a sense of curiosity about engineering, and develop open-endedproblem solving skills. The course is divided into three modules (each roughly the equivalent ofa standard one-semester course): Module 1-Problem analysis and modeling; Module 2-Experimentation and measurement; Module 3

This poses a problem in the softwareindustry, as there is generally a lack of knowledge of Software Verification and Validation(V&V) benefits and a shortage of adequately trained V&V practitioners. This project, funded bythe National Science Foundation –Transforming Undergraduate Education in Science,Technology, Engineering and Mathematics (NSF-TUES) grant, has objectives to transform arequired course in Software V&V offered to Software Engineering students at Author’sUniversity and disseminate it to the academic and professional communities.

Engineers are often important members, if notleaders, of the teams that make this innovation and entrepreneurship possible. It has become evenmore important for engineering graduates to not only understand business basics, but to be“flexible, resilient, creative, empathetic, and have the ability to recognize and seizeopportunities” 1. To help engineering graduates succeed in this environment, engineering schoolsare creating courses and programs focused on innovation and entrepreneurship, sometimesdrawing from business approaches in doing so 2.In designing these courses and

Thereare four important elements in this definition. The first element highlights an entrepreneur’sability to uncover an opportunity. Few people would disagree that opportunity recognition is animportant skill of an entrepreneur, and this skill is frequently listed as an indicator ofentrepreneurial ability or intention2,3.

Education, 2014 Conceptual Change Across Engineering DisciplinesIntroductionExisting research on conceptual change (i.e. the effortful process of revising or changing one’sfundamental understanding of something) has drawn from various disciplines including physics,biology, mathematics and history. Little research has been done, however, investigating howdifferences in content may affect conceptual change in the various disciplines [1].MethodsThe research described here investigates this question by analyzing data on studentunderstanding of engineering concepts from multiple content areas within the broad discipline ofengineering: mechanics of materials, Boolean logic, fluid mechanics, and transportationengineering. In total, this
