Although a few individual seminars havebeen changed or refined over the eight years of ETW, the intent of the seminars remains thesame – to provide content and embedded activities that orient, motivate, inform, stimulate,demonstrate, apply, and assess. Table 1 is a listing of the seminars to be offered as part of the2007 ETW which is being hosted at Northern Arizona University in July. The ETW staffconsists of engineering and construction management faculty volunteers from across the U.S.who are scholars of teaching and learning and schooled in the philosophy and methods of ETW.

The benefits of digital inkannotation are described by Hulls2 and contrasted with other teaching methods. Wise et al.3present responses to student surveys that indicate that Tablet PC use by instructors can helpimprove student learning. The above-mentioned papers use subjective instruments (such asstudent surveys) to identify benefits of using the Tablet PC for instruction.

Copyright © 2007, American Society for Engineering EducationIntroductionThe School Robotics Initiative seeks to improve student and teacher learning in regional schoolsand prospective teacher learning at the university. It is based on the establishment and gradualexpansion of a network of regional schools that will develop robotics-learning programs linkedto Cal Poly Pomona technological resources and faculty in education, psychology, andengineering. The School Robotics Initiative is implemented as a problem-based curriculumapproach designed to enhance cross-curricular learning (with an emphasis on mathematics,science and writing) at the levels of elementary through high school.1 As it evolves, this effortwill involve industry and academic experts

contentknowledge to effectively teach mathematics (Ball, 1997).1 Content knowledge is the conceptualunderstanding of the mathematics that teachers need to have in order to teach. Pedagogicalcontent knowledge involves understanding how children think and learn. Teachers who are ableto teach math effectively are able to bridge content and pedagogical knowledge. For example, astudent states that the fraction “ ¼” is smaller than “1/8” because “4 is smaller than 8.” In orderto teach effectively, the teacher must understand mathematically why ¼ is larger than the 1/8th .The content knowledge required to teach this concept involves understanding the concepts ofunit, unitizing, equivalency, partitioning and part-whole conceptions of fractions.

However, there are over 380 products currently on the market that usenanotechnology, and $30 billion worth of nano-products were sold in 2005 1.Scientists are now passing on the development of micro- and nano-systems to engineers forcreating new products. Engineers are beginning to design and manufacture micro-/nano-systems. Hence, nanotechnology is taking on an engineering approach. Now nanotechnology isbeing taught in some engineering departments of U.S. universities, and it requires a differentapproach when teaching it to engineering students. Since nanotechnology

Therefore, the tenor of the coursefollowed many other industrial engineering or engineering courses in that it focused on systemsanalysis or resource allocation. Peter Drucker was fond of quoting the nineteenth-centuryeconomist J. B. Say, stating “The entrepreneur shifts economic resources out of an area of lowerand into an area of higher productivity and greater yield.”1 As such, the course was notpresented so much as a course on how to start a business, as entrepreneurship is often perceived,but

People with impaired vision can use acane successfully to navigate in a forward direction, but often have difficulties with obstacles ateye level and with detecting openings (such as open doorways) to their sides. A team of one EEand one ME student is developing an ETA using ultrasonic sensors to detect obstacles in frontand to the sides of the wearer. Upon sensing an obstacle or a doorway opening, this informationis provided to the user by means of a tactile belt (Figure 1).

California State Polytechnic University in Pomona,California has one of the largest engineering programs in the US with over 4,500 undergraduatestudents. On the other hand, more than 84 percent of students at CPP are working during theweek [1]. In recent years, student attrition has been a problem for many engineering programsacross the nation such that a significant number of students drop out in their first- and second-year. As indicated in the EERP report on student attrition [2], the primary non-university relatedreasons students claimed for leaving their studies were the

This class covers basic dc and ac circuits,and fundamentals like Ohm’s Law, Kirchhoff’s Voltage Law and Kirchhoff’s Current Law.

As a means of describing the course coverage, the assignments that contribute to the course grades for the students will be discussed. The assignments can be divided into four general categories; those involving (1) a laboratory activity, (2) communication skills (written and/or oral), (3) a spaghetti bridge project, and (4) the final exam.

same. The simplest expression of the design process is encapsulated in ETC,Express-Test-Cycle. 7 This methodology may be explained as follows: 1. Express : This phase encompasses concept generation – brainstorming, ideation, sketching, defining the problem. 2. Test : In this phase ideas generated are tested and vetted against specific criteria. 3. Cycle : New issues inevitably arise that must be addressed, requiring a return to the Express phase.Other approaches are equally valid, but ETC is useful to make the relationship between designand convergent/divergent thinking more transparent. In the Express phase, divergent thinkingdominates. When a small group of solutions arise that are deemed preferable
