for interested students.With this in mind, students must be convinced of three things: 1) that the “gospel” of Fs ≥ 2fmax (i.e.,sampling at least twice the highest signal frequency) that they learned regarding lowpass sampling is only aspecial case, 2) that for bandpass signals the selection of sampling frequency is more complicated, and that3) aliasing is not always a bad thing. By choosing Fs properly, aliasing places the signal spectrum wherewe want it, yet avoids the overlapping of spectral replicas that would render the signal useless.7, 8A bandpass signal is one where the energy is constrained to lie only between a lower frequency of fL andan upper frequency of fU . Thus the bandwidth of this signal is B = fU − fL . One useful form of

. This paperdescribes an investigation of problem-based learning on undergraduate electrical engineeringstudents’ conceptual understanding. Fifty-five students enrolled in an electrical engineeringcourse at a Mid-western university participated in this student. The study utilized a within-subjects A-B-A-B research design with traditional lecture as the baseline phase and problem-based learning as the experimental phase of the study. Participants completed pre-post testssurrounding the four topics covered in the study. Results suggested that participants' learninggains from problem-based learning were more than learning gains from traditional lecture.IntroductionRecently, there has been a shift from using lecture-based teaching methods in the

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

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
