They were asked to answer all 27 items of CATS-s v1, rate theclarity of each question, and provide suggestion to improve unclear questions. Nine (9) of thestudents completed their BA at a Hispanic University from Latin America. CATS-s v2 was thencreated after analyzing their responses.

Unfortunately, cognitive development related toknowledge collection has been the primary focus of education in the past.Active learning has been a topic of numerous papers and research since the 1970’s and continuesto be the focus of research and methodology discussions of instruction at all levels. Thetechniques of active learning are designed to move the focus of education from primarilyknowledge acquisition to include the solution-based strategies that teach the “whole” student.Originally designed for face-to-face instruction, active learning now must be taken into thenewer realm of on-line and technology enhanced learning.

We would expect reflections to occur at both the leading and thetrailing edges of the pulse. A much more significant programming challenge would be to allowthe load impedance to be complex. While it is easy to handle complex loads in a steady statetime-harmonic situation, it is much more difficult to handle them for non-steady state conditions.Code described in this paper and other examples presented at the conference will be madeavailable on the author’s website: http://www.eng.auburn.edu/users/wentwsm/References:1.

Students would be asked to confirm the value of the velocity at, for example, 1s byusing hand calculations. These can be obtained by calculating the velocity of the connectionsbetween the driving crank and the link (329.87 mm/s at 150.37 degrees) and between the linkand the lever (262.83 mm/s at 171.06 degrees – perpendicular to the lever). Then the angularvelocity of the link can be found (0.4161 clockwise) and the velocity of the CM can becalculated (magnitude: 291.53 mm/s). For the kinematic example (Figure 3) students

Today, linear motors are capable of achieving speeds up to 5 m/s(3 m/s average), and sub-micron accuracy1, 2. In railway transportation, linear motors are used inmagnetic levitation (maglev) train systems allowing achievement of high speeds unattainable byconventional trains3. However, most textbooks on electrical machines for undergraduateengineering students either do not cover linear motors at all or provide only a cursory coverageof the topic4.Since, in general, linear motors with accompanying controllers are expensive; their use inengineering education was fairly limited. Atencia et al.5 designed a low cost linear inductionmotor that can be used for
