processes follow specific procedures or recipes. Theserecipes may be very specific, as might be the case for a pharmaceutical processes in which strictadherence to good manufacturing practices (GMP) is required for all steps in the production ofthe product. On the other hand, the recipe might be less formalized and involve some “art” as inthe case of producing a batch of special colored glass. An example of a recipe to produce achemical product is shown in Table 1, where only details of the first two steps are given. The keyelements of a recipe are the time required for each step, the equipment used, and the rawmaterials and utilities required.

One aspect of this bill was to fund the development of university education programs.These programs are described in more detail in the Department of Energy Multi-Year Research,Development, and Demonstration Plan2.Michigan Technological University is receiving federal support under this act, with an emphasison new course development, development of an interdisciplinary minor, and development ofmodules that can be used to supplement the traditional curriculum with information abouthydrogen and fuel cell technology.

disinterest in engineering career by nearly 85% of 8 to 17 oldstudents [1]. A major reason cited by the students is the lack of awareness about engineering.As most students advance through middle school science classes, their attitude toward sciencebecome more negative and their interests decrease most in the seventh grade [2-5]. Thus, themiddle grades are a critical period for students, representing the period most beneficial toprovide engaging academic opportunities. With the increase in demand of qualified engineers,the lack of interest has been thought as future problem. There has been a significant increase in academies and workshops to provide an earlyexposure to engineering, which is recognized as a way to prepare K-12 for
results.Additionally, students learn teamwork skills and oral and written communications by working inteams throughout the semester, preparing frequent technical progress reports, and delivering oralpresentations based on the project.The introduction of statistical experimental design through laboratory experiences in upper levelengineering courses has been addressed previously 1, 2, 3, 4. Ludlow et al.2 address theimportance of the application of statistics as a skill needed by undergraduate engineers andpresent a simple gas chromatography experiment which allows students to develop statisticalskills without being bogged down by a complicated experiment.

Gore CEO Terri Kelly speaks of creating a culture of “innovation” by“[creating] the right environment where collaboration happens naturally.”3 While it isclear the phrase “creating a culture” is fairly ubiquitous in modern society across variousplatforms, a standard connotation of this phrase is much less so. Accordingly, we definethe term culture in this work to mean “the relationships, interactions, activities, andevents involving the department, its faculty, and its undergraduate students.”As it relates to academia, culture within a department is experienced by

The survey is now conducted by the AIChE Education Division.This year’s survey focuses on the freshman engineering courses and details how freshmen areintroduced to engineering, what topics are taught, in what environment they are taught, and howthey are assessed. Teaching methods and novel approaches are focus elements of this survey.While the survey focuses on courses specific to chemical engineers, innovative teaching methodsin general introduction to engineering courses are included as well.1.

This assignment was executed between the second and third exams of the semester.To establish the “pretreatment” condition, scores from the second exam were compared betweenboth groups. Statistical hypothesis testing indicate that there is no significant difference betweenthem (i.e. Group #1 mean = 78.32, while Group #2 mean = 81.94). In
“Engineering Techniques”.“Engineering Techniques” is a freshman engineering course offered each fall semester and takenby all engineering students. This course is an introductory course designed to acquaint freshmenwith the fundamental concepts of various disciplines of engineering. Engineering Techniques isa 2 credit hour course consisting of 1 one hour lecture per week and one 2 hour laboratoryperiod. The laboratory experiments are drawn from the various engineering disciplines. As anintroductory course, it is essential that the level of difficulty of the experiment and the analysis ofthe results be appropriate for the academic level of the students. That is, some students enrolledin the course are taking pre calculus.The experiments in Engineering

22.139.2Technology reported in 1997 that significant investment needed to be made in understandinglearning and supporting the development of best practices. In supporting best practices, thereport emphasized the need for large-scale studies to determine best practices and provideinformation on generalizability.1 The Interagency Education Research Initiative, formed inresponse to that report, was created to support research and develop a knowledge base to“support the development, testing, and implementation of scalable and sustainable interventionsto improve teaching and learning, particularly through the use of technology.”2 Additionally,funding agencies like the National Science Foundation (NSF) require a “broader impact”component in all grant proposals.3

Page 22.157.1 c American Society for Engineering Education, 2011 Alternative Lab Reports – Engineering Effective CommunicationIntroductionFor many chemical engineering undergraduate programs, required laboratory sequences allowstudents to experience hands-on applications of chemical engineering principles outside theclassroom. After students have successfully completed their laboratory experiments, their resultsare analyzed and typically written up as a classic laboratory report [1-2]. In addition, prior totaking their chemical

As theuser defines the flowrates assigned from the process streams (sources) to the process units(sinks), infeasible solutions are detected and the student’s score is penalized. When a feasiblesolution is finally obtained, the grade is assigned based on the number of trials and the ratio ofthe student’s answer to the optimal value.

In 1999, as a response to ABET’s EC2000 criterion, a list of specific competencieswas defined in the Chemical Engineering Program at Brigham Young University that, whentaken together, constituted each Program Outcome. When the competencies were firstdeveloped, it became clear that the level of mastery expected from students varied fromcompetency to competency. Exposure to the material was all that was required for somecompetencies. For others, it was our expectation that students should not graduate withoutdemonstrating a specified level of mastery. The expected level of mastery is intimatelyconnected to the types of practices, assessment, and feedback associated with a givencompetency. Consequently, a mastery level of 0, 1, 2, or 3 was

The ICC module design follows a standardized protocol thatincludes four major sub-components: (1) pre-testing to quantitatively assess existing studentknowledge; (2) a set of topic notes so that students can perform a self-paced on-line review; (3) aseries of exercises and problems that allow the effect of various model parameters to be studiedin a conversational type of mode with graphical output; and (4) post-testing for quantitativeassessment of student knowledge progression for validation of the desired modules outcomes.

This approach showed promising results in terms ofstudent engagement and enthusiasm.After the initial success, we determined that it would be necessary to address the issue of laboratoryspace if this pedagogy were to be implemented at other institutions. To this end we developed theDesktop Learning Module (DLM), figure 1 (Golter, Van Wie et al. 2006). The DLMs are a systemconsisting of an approximately one cubic foot base unit and a series of modular cartridges. The baseunit contains pumps, flowmeters, thermocouples, water tanks, and
correlation between technical research and effectiveteaching [1-3], a few studies have found a positive correlation between the two [4]. Astin in hismonumental work reports that research-oriented universities in fact impact negatively on meas-ures of student cognitive and affective development [5]. Astin attributed this to a low prioritygiven to undergraduate teaching at such institutions. This low priority to teaching is also tied tofaculty hiring and reward structure which is heavily skewed towards research output because ofthe dependence of most universities on external research funding [6]. Interestingly, universitiesand community colleges which have teaching as their primary goal are striving for more researchoutput because they too want to

To answer these questions, we investigated the engineering teams in a chemicalengineering design capstone course for seniors. We assessed the possibility that the differences,rather than being due to team demographics or GPA discrepancies, were actually due to minutepersonality type differences among team members. We gave students the Myers-Briggs TypeIndicator® (MBTI)1 at the beginning of the course, but did not reveal their types to them so thatthey would not modify their behavior based on that knowledge. Throughout the course, theinstructor kept notes on student interactions during team meetings and

effect on student learningexperience in PD&C at Rowan University.The Undergraduate Process Dynamics and Control CourseThe Accreditation Board for Engineering and Technology (ABET) stipulates that chemicalengineering graduates are able to “design, analyze, and control physical, chemical, andbiological processes” [1, emphasis added]. These processes are intrinsically dynamic, in the sense thattheir variables are constantly changing with time; yet in most chemical engineering programs,the first and only course that focuses on dynamic behavior is PD&C. In this single course,students are required to develop a wide range of knowledge, abilities, and skills (KAS) coveringboth dynamics and control, such as those defined by Edgar et al. and

All eight programs have agreed to make comparisons of the knowledge gained,retention, and student attitudes between a typical class approach and a studio-based approach.Studio-Based LearningStudio-based learning (SBL) techniques have been used in a variety of disciplines, most notablyin architectural education.1 The technique is rooted in a type of constructivist learning theorycalled sociocultural constructivism.2 The studio-based approach typically encompasses four keysteps (see Figure 1). 3 First, students are given complex and meaningful problems for which theyhave to construct solutions. Second, students present their solutions and justifications to theentire class for

Not only is there general interest in the chemical mechanisms behind “typical”food, but molecular gastronomy as a high-end cooking approach (as seen in thegroundbreaking el Buli and Alinea restaurants) is generating significant interest. Whilethe fraction of chemical engineering graduates going into the food and consumer productssector has held relatively constant at 10-20% for decades (1), at our institution thefraction of our graduates heading into such industry has increased from slightly below thenational average to slightly greater during the past decade.

practical pieces to relate to.Students’ feedback at the end of the year (2006-2009, 2011) noted disconnects between theoryand real world examples, complaints about the mathematics/equations used throughout thecourse, and finally not enjoying the textbook by Smith and Van Ness[1]. During the Fall semester,2012, we developed a new approach to the course with two goals: 1) students will actively readthe book[2], 2) students will reflect on thermodynamic learning[3] and also self-assess learningtechniques.In previous years, the Thermodynamics class at our University would consist of a typical lecture,followed by solving problems in group format. This semester, class time changed to a readingactivity, followed by a concept clarity feedback, and then
