material based upon previous knowledge that they may have.To measure student learning, pre- and post- Materials Concept Inventory (MCI) exams wereadministered. The MCI is a 30-minute, multiple choice exam that is available on-line and measuresstudents’ conceptual knowledge and reasoning. A sample MCI question regarding electrical conductivitybetween aluminum and glass is as follows: Aluminum is a better electrical conductor than is glass becausealuminum: a) has more total electrons per volume b) has more conducting electrons per volume c) haselectrons which move faster d) has electrons which move slower e) has more conducting electrons pervolume and they move faster than those in glass. The topics in the MCI exams are as listed in Table 3
into a digital image. An RGB digital camera is commonly used for image acquisition especially if the desired object has a color contrast with respect to the background. Some applications require a special image acquisition system like a thermal camera or an infrared camera8. 3. Image processing acts as the brain of the machine vision and is typically composed of pre-processing, segmentation, and feature extraction. a. Pre-processing – modify and prepare the raw image to produce an image data that is suitable for subsequent operation. An example is increasing the intensity of the image pixels. b. Segmentation - the desired object is differentiated from the background. The

These questions are intended to provideexamples of the types of questions that could be included in an assessment of engineering andtechnological literacy that is generally applicable for use with undergraduates who are notstudying engineering. As in the case of the Force Concept Inventory, it would not be advisable toinclude the entire assessment in a publication which might be accessible to the students beingevaluated.Sample Draft QuestionsTECHNOLOGY and SOCIETY1.)

, subsystem isolation, and requirement relaxation. Usage of the flowcharts is explained later in the section. 6. Estimate the cost, in terms of person hours and also dollars to complete each iteration of each concept, then determine which concepts to construct in parallel. The principles to this step are: (a) that the highest ranked concepts should be considered first, (b) as many concepts should be included as possible, (c) but a concept should not be pursued if the estimated cost of pursuing that concept exceeds available budget (i.e. the cost of all iterations).A generalized view of this process can be seen in Figure 1.

Unmanned Aerial VehicleUnmanned aerial vehicles (UAVs), such as the one shownin Figure 3(a), are becoming less expensive and easier touse. This makes them ideal for search and rescueoperations. The ACME company makes a UAV that can bedeployed by hand that automatically flies a spiral searchpattern like the one depicted in Figure 1(b). This patternmaintains a half-mile distance between passes to guarantee (a)the plane will pass within a quarter mile of any person inthe search area.The path of the plane is described by the equations andwhere and represent the coordinates of the UAV andare expressed in miles. The parameter has no physicalmeaning, but is used to delineate where the plane is on

While these two issues are intimately connected, they are oftendecoupled.9 These problems remain intact, as evident by the continued poor performance ofengineering students in thermodynamics, Fig. 1. This strongly suggests that either a) theattempted solutions did not address the problems, or did not treat the root causes, or b) thesolutions that worked, or worked partially, were not adapted by a sufficiently wide population ofuniversity instructors such that a clear improvement in students’ performance at the nationallevel is achieved. None of the attempts seemed to be comprehensive- each targeted few certainconcepts and/or principles.Common engineering thermodynamics textbooks have not been affected by the incrementalsuccess of some of the

ofagreement indicates that raters score skills within ±1 point on a five point scale at least 90% ofthe time. The literature further indicates that acceptable agreement occurs when different ratersagree to within ±1 point on a five point scale at least 70% of the time. For exact matches, highlevels of reliability occur when different raters match exactly at least 50% of the time, and exactagreement at least 30% of the time indicates acceptable reliability. Our analysis of ratings foreach of our 19 skills showed, in general, that the reliability of the overall rubric is acceptable.However, there was some variation in the reliability of each skill.

one of the three states, students who complete an associate’s degree at acommunity or other state college or university are given preferential admission at public, four-year institutions. Furthermore, some states have created “transfer blocks,” or sets of courses thatare often taken at a community college, which will transfer to a particular program if the studenthas earned passing grades in all the required courses. Five states with MIDFIELD institutionshave established transfer blocks for engineering; two of them include the engineering transferblocks as part of the associate’s degree, and students with satisfactory GPAs are guaranteedadmission to the MIDFIELD engineering schools in those states.Table 3 in Appendix B shows the range of
