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

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).

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
