values would be most meaningful andappropriate for this process. Typically, students chose water temperatures in the range of 70 - 95°C and times between 30 s and 6 min. Some teams chose wider ranges of temperature or timeand would subsequently observe differences in the significance of the factors. Additionally, aseparate set of experiments were conducted to determine the value of the standard deviation. 1 2 Figure 1. French Press Coffee Maker.

by a retired industrial practitionerwho had a good idea of the types of deliverables that were representative of what studentswould encounter in the workplace, but this may not be the case today. In addition, theadvent of process simulators in the 1970’s and 1980’s had a huge impact on the way thatsenior design is currently taught. This paper summarizes the author’s selection of themost effective, innovative approaches for the capstone design course reported recently inthe literature or discussed at previous conferences. The challenges associated withteaching senior design, and approaches successfully applied to address these challenges,are also described.IntroductionThe senior design course in chemical engineering typically includes both

The specifics of equipmentdesign and simulation for other batch unit operations (distillation, filtration, crystallization, etc.)are not covered but are left for specific operations related to the group project.As an example of the differences between unsteady, batch operation and continuous operation,consider the preheating of a batch reactor with preheating of a continuous reactor in a continuousheat exchanger.

In addition, a literature and database searchshould identify recent activities of the company, including current business, technical and legalsuccesses/problems. This activity prepares the students to be more active in a subsequent mockinterview with the course instructor.We position the resume/corporate profile and mock interview writing assignments early in thesemester, so they aid students preparing for the Engineering Career Fair as well as corporateinterviewing on campus for summer intern, co-op, and permanent positions

Further, she notes that the gap between educational research and educationalpractice has been an ongoing phenomena and complaint of educational researchers since at least 1934.Careful experimental design was a focus of educational research in the 1960’s, but such research did notresult in broad and rapid adoption of researched

A Honeywell Experion DCS system was purchased forthis purpose. This DCS system is much less bulky than its predecessor, the TDC3000, whichuses predominantly 10base5 cable with BNC connectors, and is commonly found in manyrefineries and chemical plants. A major factor contributing to this reduction in bulkiness is theHoneywell Experion’s use of CAT5 Ethernet cable in place of the TDC3000’s bulky and stiff10base5 coaxial cable connectors, which allows this system to be implemented using equipmentfound in a typical campus computer lab.

Third, the examemphasizes the importance of the Level-3 competencies to our students and faculty. Students arekeenly aware that retention of knowledge and skills in the core areas is a requirement forgraduation in addition to simply completing required course work. Faculty awareness of theneed to help students learn fundamental concepts is also heightened.Table 2 shows the 18 Level-3 competencies assessed by the exam.

enrollment in anEngineering Freshman Learning Community is 14/20 (70%), compared to an actual EFLCenrollment rate of 61%. The electronic survey covered Supplemental Instruction and Peer-LedTeam Learning for General Chemistry I, Pre-Calculus and Calculus I. Enrollment data (Table I)indicate that about 2/3 of Fall quarter freshmen should be enrolled in either Pre-Calculus orCalculus I, and at most 1/20 should be without a Fall math class. On the survey, 1/22respondents stated that (s)he did not take math in Fall, which is consistent with enrollment data.An additional 3/22 students did not identify a math instructor; two of those answered noquestions beyond those about the EFLC, suggesting that they simply stopped participating in thesurvey. It is thus
