After the responses were collated and similar themes combined by theDCI team, the experts were asked to examine twenty-four different concepts. They ratedeach concept on (a) how important it is, and (b) whether or not their students understandthe concept.The twenty-four resulting concepts were then ranked according to importance and difficulty.As the goal was to design a thirty question test (similar to the FCI), ten concepts wereselected so that each concept could be tested more than once.

table is a convenient way to display data that allows two variables tobe compared with each other. In cross-tabulation tables, we can see frequency counts of howmany students selected each answer for the two questions. By observing the individual entries ineach row and column, we can determine how many students answered both questions correctly.More importantly, when students answer both questions incorrectly using wrong answers that arerelated conceptually, we have obtained evidence of a misconception which carries across thecontext of both questions. For example, the results in Table II indicate a strong correlation forthe correct answer pair (c,f) as well as two sets of incorrect responses (a,e) and (b,g); theincorrect response pairs can

IMAGE PROCESSING ALGORITHM Each pixel in each captured image contains information in the form of three 8-bit binarynumbers for red, green, and blue (R p , G p , B p ) . One way to characterize each pixel graphically is tocreate a color vector in 3-dimensional space with pure red, pure green, and pure blue as orthogonalaxes. Figure 3.1 illustrates such a color box where one can draw color vectors for pixels. Themagnitude of this color vector represents the overall brightness of the pixel and the direction of thevector represents the relative color in the

adopting these types of projects at thefirst year level 13-17, we address these issues. The overall goal is to provide guidelines forengineering educators that would make their implementations more successful in terms ofenhancing student learning and student retention in engineering disciplines. To this end, weassert that a comprehensive study (which is underway), should involve the following steps: 1. Assessing the appropriateness of industry-sponsored project selection in terms of: a. Relatedness of the design project to the engineering discipline of choice for students, b. Gender orientation of the project domain, c. Ambiguity of the project and student readiness for open-ended problem solving
