Such students are most likely disadvantaged in terms of both subjectskills and inclination to further study. The American Society for Engineering Education,reflecting the nation‟s anxiety over the situation in the U.S., in 2003 established a K-12 &Pre-College Engineering Division (website available at http://k12division.asee.org/).Many universities are now funding outreach programs to increase the number of engineeringundergraduates 4-15. Ideally, such outreach programs should have two positive outcomes:participating students should be both better prepared for and better informed aboutengineering careers.

Electrical components to condition,store, and deliver power to the load may be a mixture of analog and digital, whilecommunications may be performed in a number of frequency bands and network protocols.

Accompanying these developments in the Technical College Sector was therise of an Association for Liberal Education that had its own research officer [9].It will not have escaped the notice of the reader that no mention is made of universitystudents in technological studies receiving such treatment. Why should a person on adegree course be treated differently? The concept of liberal education has a long historythat can be traced back to the Greeks, and Davies provides an all too brief history of thedevelopment of liberal education from those times [8.ch 1]. From the Greeks and theRomans we get the notions of being free to learn, and as Davies notes

A systems thinkingapproach regards social, environmental and economic factors as necessary components of theproblem solution. Because it is a whole systems approach it also encompasses sustainability. Wehave integrated systems thinking in the following ways; 1) new material has been included intokey courses (e.g. the first-year introductory and senior design courses), 2) a sequence of threerelated environmental and transportation systems courses have been included within the curricula(i.e., Introduction to Systems, Decision Making, and Modeling), and 3) service-learning (S-L)projects have been integrated into key

One improvement that wasmade to this method during the mid 1900’s was to replace the metal sheet with a sheet ofconductive paper with a lower conductivity2. This method is still in use today. In fact,several educational companies, including Pasco3 sell equipment to run this kind ofexperiment. By using either metal or more recently paper, two-dimensional potentialfields can be plotted. Advantages of using conductive paper include lower conductivitythan metal and readily available supplies of the paper. A disadvantage is that theconductivity of the paper is often inconsistent causing errors in the field.Another device

This model couldultimately lead to integrating the enduring understandings needed to make sense ofnanoscale phenomena with effective pedagogical methods.
