reduced.The following chart shows the top 20 topics as rated by the respondents, and the bottom 20 topics.These are in ranked order with the #1 topic being the highest rated. Beside each topic are threecolumns: 1. Column #1 asks if the topic is core to the objectives of the academic program making the evaluation. An ‘A’ indicates it is considered Essential for their majors; ‘B’ indicates it is Important; ‘C’ indicates it is Good to include; and ‘D’ indicates it is Not significantly important. 2. Column #2 estimates the number of hours students are presented or work with that topic area. Page 23.149.3 This indicated the
approach used in class is to start with configurations of simple distillation columns (one feedstream and two product streams), and then progress to more complex column arrangements.Specifically, distillation column sequences with simple distillation columns are presented as amethod for separating ternary mixtures. This is a base case scenario shows how two or threecolumns may be sequenced to separate three compounds, as shown in Figure 1a. In this casethere is no thermal coupling between the columns, and each column has a reboiler and acondenser. A A, B A
stress distributions in the profile key seat with the r/B= 0.0832 under torsion, bending and axial loading will be investigated in order to find the maximum shear or normal stress’s locations on the key seat.(2) The profile key seats with the r/B=0.0832 on the corresponding shaft diameter for every standardized key will be investigated through FEA to explore the effects of shaft nominal diameters on stress concentration factors under bending, torsion and axial loading.(3) The shaft models with the same shaft diameter and the same key seat having different r/B will be numerically simulated to investigate the effects of the r/B on the stress concentration factors.2.1 The stress distributions in a profile key with the r/B=0.0832
moving quickly to embrace these safersystems and these laws are taught in the safety portion of the advanced course. Theequipment that had been used in labs over the years was not safe and the safety issue hadto be addressed in any change of lab design.Software licensing had become an issue. A-B has a relatively new concept for licensureincluding a unique MAC address per copy. While the lab had enough licenses, thepractice of ghosting the software onto an entire lab of computers would not work with thenewer A-B software.Evaluations for the advanced course were spotty at best and less-than-acceptable at worst.Evaluations were even more dramatically negative with students at exit interviews for theEET program just prior to graduation.

DOE (also known as experimental design) isa structured approach used to establish and quantify causality relationships between independentvariables (factors), as well as their interaction effects, and the outcome of an experiment. TheDOE approach can be applied broadly to many fields outside of engineering, including finance,health and social sciences9.To illustrate the DOE method, suppose that you are planning a series of experiments thatinvestigate the effect of three independent variables (A, B and C) on a measured response (Y). Afirst impression may be to vary each of A, B and C one
summer sessions, but not all. In the last two years morethan one section of the course has been offered during fall and spring semesters. Figure 1displays the percentage of grades of A+, A, A-, B+, B, B-, C+, C and C- (ABC rate) assigned bythe instructors for each section during this period. It should be noted that until fall 2011, thegrading scales did not include “+” or “-” letter grades. In Fig. 1, the instructors are identified asInst-1 through Inst-9. An examination of grade distributions shows that there are smallvariations in passing rates for a given instructor from semester to semester. A higher passingrate for an instructor for one semester may be due to an uncommonly good pool of students. Thegrade distributions in Fig.1, however

may be counterintuitive that an online tool would encourage contact between studentsand faculty. (See first row of Table 1). Nevertheless online methods providing a flippedclassroom environment, can improve provide the effectiveness of available face-to-facetime3. Thus contact between students and faculty can improve by employing a hybridtool. Also if the hybrid can help a student formulate questions or bound uncertainties,then it may foster better students / faculty exchanges.A forum type of venue could provide a useful means to engage students with open-endedtypes of questions. For example, students could be asked, “How might you address agiven situation (method A vs B) and why do you prefer this approach?” or asked, “Whatdid you learn of

In order to illustrate the degree of variance from the geometric configurationsthat students were asked to visualise and communicate, a superimposed wireframe model ofthe original objects has been placed on top of student solutions in the second part (b) of theimage. The first, second and fifth configurations were chosen to investigate the issue
. Remote ExperimentationThe lead author has been working on remote laboratory development and implementation for Page 23.807.3more than ten years. During this period, he has attracted research and development grants fromthe National Science Foundation and industries. Some of these developments are used to deliverlaboratory courses within an electrical engineering technology program. This section willprovide an outline of those developments.To maximize the benefit of remote laboratories, the facility design philosophy includes a numberof features: a) use of emerging technologies; b) individualized learning; c) knowledge-centeredlearning; d

The rubrics for oral communication, writtencommunication, and teamwork are included in Appendices A, B, and C, respectively.For the pilot study, the rubrics were used to assess student performance in upper-level courses inComputer Engineering Technology (CET), Electrical Engineering Technology (EET), andMechanical Engineering Technology (MET). Since the goal of this outcomes-assessment was theevaluate students’ performance near the end of their senior year, instructors provided scores inthe three rubrics for each student in the capstone courses. A vital part of an assessment process isto identify areas for improvement,4 and so the results were
