position differentiation isviewed as very course content specific. Thus, there may be variation in the way the twoinstructors covered this content. Although WEB students did better on the change managementitem than did LEC students, in general, this item had a very low correct answer rate, suggestingone of several possibilities: (a) content may not have been taught, and/or (b) the item may bepoorly constructed.The differences between the percentages of correct response for the WEB students versus theLEC students were lowest in the following content areas: ≠ Life stage transition ≠ Organization management/culture ≠ Employee supervisionThe COST course provides an applied approach to the collection, analysis, presentation

Figure 1, for example, shows a typical configuration of a dataacquisition system offered by AIM Sports specifically designed for motor racing.Both, the data collected and the analysis performed by the use of data acquisition systemscan be subdivided into suitable categories. This subdivision normally depends on theintended application of a data acquisition system. In car racing, for example, it is Page 14.1257.5common to break down the collected data into the following categories:(a) Vital functions of the car,(b) Driver Activity, and(c) Chassis Physical Parameters.The number of

Only a veryfew (4 percent) included students analyzing data (D) and wrote that they would explainthe results based on science (E). None of the teachers mentioned the final parts of theinquiry process: (F) students revise models, (G) students present a consensus model, (H)students conduct additional experiments, (I) students further revise the model, or (J)students present final model. When combinations of steps in the inquiry process wereanalyzed, we found that the most commonly listed step (C—observations/experiments)was most frequently combined with B

(http://www.historylink.org)and soon decided to start producing his own airplanes. Together with Navy Lieutenant ConradWestervelt and Herb Munter, Boeing designed and built his first airplane, a float plane namedthe B&W. Shortly thereafter, on July 15, 1916, Boeing incorporated his aircraft manufacturingbusiness as Pacific Aero Products Company, a name he changed to Boeing Airplane Companythe following year. In early 1917, Boeing hired two students, Clairmont L. Egtvedt and Philip G.Johnson, from the University of Washington, to be his engineering staff. Though

In a telephonesurvey, respondents were asked if they had seen women in several professions, whether theythought men would prefer a spouse who was either an elementary school teacher or in one ofthose professions, and whether they agreed that women could be in certain professions.

Some variability is expected in the responses, but this serves to encourage classdiscussion. The majority of students compute (b), which is probably the right answer, but it isinteresting to hear what assumptions lead students to pick (a), (c), or (d). The students noticethat no groups that do a realistic calculation pick (e).Question 2: Referring to Figure 1 (below), none of the bolts will fail under the loads indicated.Rank the bolts according to how near they are to failure (closest-to

The blender is also used in a guided-inquiry laboratory exercise. The laboratory worksheetsfor the exercise are included as Appendix B. Students perform a laboratory exercise that takestwo hours. The laboratory exercise uses guided-inquiry to lead students to discover how theenergy storage and shaft work are manifest in the behavior of the blender. The thermocouplesignals are acquired from the DAQ, are displayed with a LabVIEW VI, and are post-processedwith a MATLAB program. The focus of the exercise is on manipulating hardware and collectingdata
meeting, you can ask the TA for any feedback that (s)he isgetting from the students. This is important, because students are often more willing to discusstheir difficulties with a TA than they are to discuss them with you.4. ContractsExperience indicates that few instructors enter into contracts with their TAs, but it is a goodpractice, because it makes explicit the expectations, and therefore makes it more likely that thegoals will be met. Appendix A and Appendix B contain two sample TA contracts. Thoughneither is from engineering (they are from Sociology and Hospitality & Tourism Management,respectively), both are indicative of what could be included in a contract for an engineeringcourse. Note that both of them stress the importance of

I summary, the generator has two main purposes: a) to be connected to the 3transmission of a bicycle so that a cyclist can generate electricity, just by riding a regular bikethat becomes a stationary exercise machine, and b) connect it to a propeller to harvest energy atlow-wind speeds. Hence, this project intends to impact two modern society concerns in anintegrated way: usage of alternative energy sources and developing of attractive human exerciseactivities. For isolated villages and colonies around the world, and even in developed countries,this project presents some ideas to supply them with electricity. 2. Design and Construction of

The students soon realize thatalthough there are specific goals to be met in a design, there are also inexplicit objectivesrequiring an evaluation of engineering uncertainties and engineering judgment in decision-making. The students are therefore challenged to base their decisions on sound engineeringreasoning and forecasting methods, including multiple iterations of a design with differentapproaches, and to

Studentsencounter two challenges: a) the integration of multiple modes of representation of a particularphenomena or problem19, and b) the learning skills necessary to create representations ofphenomena in an iterative manner to further their scientific thinking20.

Setup In order to measure the stiffness of the model, students used two probes from Pasco:Force Sensor and a Motion detector. One laptop with Data Studio from Pasco was used todynamically record the force applied on the structure and the associated displacement, Φx. Themodel and test set-up are shown in Figure 10. The students completed this test both before andafter their retrofits to see the effects. ii. Examples of data analysis The students choose to conduct at least three trials for the same model.

Rather, the need for understanding analytical concepts andaforementioned strategies mattered more in E/CS education. As such, the infusion of constructsinto a quasi-bridge system was more complex.
