For example, skill “k”, i.e.,have developed a commitment to quality, timeliness and continuous improvement, is ranked as#1, #4, and #6 with equal number of responses for each rank. Similarly, the range of rank variesfor skills “d’, “e”, and “f”.According to this analysis, it also turned out that skill “b”, i.e. apply current knowledge andadapt to emerging applications in mathematics, science, engineering and technology, does nothave a clear ranking at all since there is no consistency in the responses as to where that skillbelongs in ranking.In order to get the variances and no rank situation taken care of, the survey data was alsotabulated according to cumulative number of rank response for each skill.

Authority says: “do it” to avoid punishment. b. Egoistic—“what’s in it for me, you scratch my back I’ll scratch yours” approach.Level Two, Conventional Morality a.

This requirement is at odds with the traditional education system which is based onformal lecturing. Radical changes are thus necessary: the assignment of projects can provide theproper environment for the students to develop the abilities to solve real problems 4.In a more recent work Yerlici -interested in the philosophy of engineering education- suggests theneed of introducing in the learning process, the concept of innovative thinking by implementinghonor programs.

is how long it takes for the actual cost of manufacturing the product to equal the target cost. Initially the actual costs should be higher than the target costs for a number of reasons, including: • Operator learning curves • Supply chain establishment & stabilization • Process tuning • Design and document errors If the downstream manufacturing personnel actively and effectively participated the early stages of the development process the initial production disruptions caused by these factors should be minimal and quickly resolved. This participation is reflected in the initial difference between the actual and target costs and how long it takes to bring them into parity (A & B respectively

Each plot shows the percentage, either for all respondents or forrespondents from each school, on self-rated skill level in each topic. The first questionconcerned the respondent’s skill in creating, editing and incorporating images into coursematerials using the computer (Fig. 1a). The second concerned the respondent’s skill in creating aWeb page for a course to provide information and distribute course materials (Fig. 1b).The most noticeable feature of these figures is the uniformity of distribution of skill levels acrossthe coalition

To obtainthe black and white picture, each pixel of the color picture was separated into three main colors;red, green, and blue. The arithmetic average of the main colors ((R+G+B)/3) was calculated foreach pixel and recorded at the same pixel to obtain grain scale picture as follows: c = colorRGB Blue = Int (c / 65536) c = c - Blue * 65536 Grean = Int (c / 256

Then that still picture is converted into the screen shown in Figure3(a). Objects surrounding the robot (workbench, human hands and pulleys) are removed as theanimation progresses and the vector kinematic model is shown with the robot body (Figure 3(b)).Finally the picture of the robot body is removed and the vector model used for the mathematicalanalysis is displayed (Figure 3(c)).

Naturally for complex exponents the complex exponential functionis needed, which requires knowledge of the power series expansion of ex. With time being ofthe essence, it is problematic to develop sequences, series and power series at the end of MathIII (largely equivalent to the second calculus of four) in order to introduce the complexexponential function and then treat differential equations. The authors’ solution was to followthe path described in [La] and define ea+ib:=ea(cos(b)+isin(b)). In this fashion a complexexponential function with the right properties

At the outset, the differencebetween the two groups of students (non-ESP and ESP) was considerable: almost 19 points inthe mean math readiness score and almost 60 points in the mean math SAT score. Such gapswould ordinarily translate to differences in mean course grades of about a letter (B versus C,e.g.) and in mean common final exam scores of several

Half the global students and half the sequential students, Group A,were channeled to the sequential module, while the remaining students, Group B, used the globalmodule. The third and final module was also designed with sequential and global variations withidentical content.

population when looking at theaverage results. One might expect the hands-on content to help these students the most. For theS-type students, the greatest benefit, when compared with the “all” category, was found in thetorsion and combined loading modules. The N-type students almost always showed lower ratesof improvement. The V-type students did exhibit significant improvement on one of the bendingquestions and one of the combined loading questions, however the small sample size of V-typesmakes it difficult to arrive at any firm conclusions. Not surprisingly, the K-type student appearedto derive significant benefit from all three modules.3.4.
