In the spring of2008, twenty-two teachers, one from each elementary school in four school districts (District A,District B, District C, and District D), were designated as lead teachers by the school systems.During the summer of 2008, the lead teachers were trained in teaching EiE. The teachers were Page 15.1171.2supported by professors of engineering, technology, mathematics, and science from twocommunity colleges. During

The parameter a(u,v) is usedto avoid having an optical gain greater than unity, while b(u,v) is used to overcome the poleproblem otherwise associated with a normal inverse filter. Since the power spectra of the addresscode can be pre-calculated, implementation of this filter does not deteriorate the

Figure 1 presents both theworksheet problem, as well as the associated diagram. Problem 4: The ferris wheel shown rotates counterclockwise about point O such that at a given instant the acceleration of point A is aA = - 80i - 60j fps2. At this instant, what are the tangential and normal components of the acceleration of point B? What is the velocity of point B?Figure 1: Worksheet Problem Statement and Diagram for Rotation About a Fixed AxisThe motion for this particular problem is not complicated, and the diagram alone or incombination with

define problem-solving as “the cognitive process directed atachieving a goal when no solution is obvious to the problem solver (p. 287). xvi” This definitionsuggests that problem-solving has four characteristics. Problem-solving is 1) cognitive (i.e., it isan internal process that occurs in the person’s mind), 2) process-oriented (the manipulation ofknowledge), 3) goal-directed (i.e., the process is guided by the person’s goals), and 4) personal(dependent on the person’s skills and knowledge). According to Donald xvii, the problem-solvingprocess in engineering involves the following thinking skills: a) Breaking down complex problems to simpler ones b) Appling fundamentals to new problems

adjustments to the grades. For instance, ifnobody in the group was able to solve a particular problem the score associated with it may be added tothe raw scores. Control over the average of a set of grades is limited by the value of the highest rawscore, which may sometimes be a disadvantage.3. Flat scale (b) (M3)Raw scores are translated by a certain number but the highest scaled score and other scores can belarger than 100 %.y% = x%+ b% (3)(b= an arbitrary percentage)For instance, all but one raw score are within 35%-80% and there is one single score of 96%. Accordingto the instructor’s judgment, an x = 10% is added to all scores in order to obtain the numerical grade.Hence, 35 is scaled to 45 (= 35%+10%), 80 is scaled

For instance:consider a system that controls warning lights for a car. Figure 2 (a) shows a portion of codeusing multiple variables, and Figure 2 (b) depicts the same code using structures and unions. Themost obvious difference between these two pieces of code is the amount of typing required foreach. The code in Figure 2 (a) requires more typing and is very repetitive. In addition torequiring less typing for this portion of the project, the code in Figure 2 (b) organizes the codeinto layers and gives this section of the project a sense of hierarchy. Furthermore, the code inFigure 2 (b) contains

Open questions wereformulated to stimulate having a free discussion about the question domain. An analysis ofthe interviews indicates that experts use analogy to establish relations between the case inhand and other cases; this may or may not be useful in terms of solving a failure problem, butit becomes part of the knowledge stored by the
