and then develop a flowsheet of the process as they envision it.This gives the students an opportunity to see how the various pieces of equipment can come together to form asuccessful design. The students then perform detailed material and energy balances around the entire processand around selected pieces of equipment (material- and energy-balance problems associated with this casestudy may be found in the reference cited above). Depending on the timing of the case study during a semester,the material and energy balances either replace or reinforce homework problems. It is emphasized to thestudents that, at this early stage, they are not expected to know every detail of the design, but that by the end ofthe curriculum they will be able to
ethics education that crossescognitive, affective, psychomotor, and social domains of learning, driven by a motivational cyclethat includes autonomy and value. Studies have also found that engineering co-curricularactivities can contribute to students’ ethics education [11-13].A number of papers have been published that provide examples of ethics education in chemicalengineering courses [14-21]. Surveys of how key chemical engineering courses are taught havedetermined that within material and energy balances courses, ~44% include ethics, ~44% includesustainability, and ~62% include safety/health/environment [22]. Within capstone designcourses, the percentage that included various ESI topics were: 37% ethics, 16%sustainability/life-cycle analysis
questions used in the new SAM cur-riculum were similar to those from the traditional courses. Comparison of student performanceshowed that SAM students performed as well as or better than traditional students in both multi-ple choice and work-out problems in the area of dynamics. A similar study, but with a smallsample size, was conducted at the University of New Haven in the chemical engineering pro-gram23. The original sequence of two sophomore courses (Fundamentals of Chemical Engineer-ing I and II) focused on material and energy balance applications using a traditional approach.The new curriculum included a SAM course discussed earlier followed by a course that providedmore depth in material and energy balances.

situations.3 However, science and engineeringclassrooms often reward students more for rote learning than for conceptual understanding.4, 5There is clearly a need for more emphasis on conceptual understanding and concept-basedinstruction.Concept-based instruction (e.g., ConcepTests, concept inventories) often depends on high qualityconcept questions. These questions can be time consuming and difficult to construct, posing oneof the biggest barriers keeping faculty from implementing this type of pedagogy.6, 7 The AIChEConcept Warehouse decreases this barrier by housing questions pertinent to courses throughoutthe core chemical engineering (ChE) curriculum (Material and Energy Balances,Thermodynamics, Transport Phenomena, Kinetics and Reactor Design
prior courses thatare not formulaic, they often rate them as being harder or complicated. The transition ofbecoming more broad-thinking in problem approaches is a difficult one, even for very hardworking and bright students. Concept maps enable instructors and students to more concretelydescribe connections among different course topics and to place new knowledge into acomprehensive problem solving framework.Examples of concepts maps from a series of chemical engineering courses are used to discusshow the idea of concept maps can be used in different ways. Concept maps built over thesemester for a sophomore material and energy balances course are used to highlight how layeringof new concepts and an inherent increase in complexity leads to a
section of the course on Life Cycle Assessment [39] (LCA) which is a method formeasuring the environmental impact of an object through every step of its existence. We beginLCA with the basics of material and energy balances and explain the importance of the laws ofconservation of mass and energy to engineering calculations. We end the class by giving studentsperspective on the different stages in production that can drive environmental impact(particularly energy use and raw material extraction) and discuss minimizing environmentalimpact via their second project presentations.Student Learning OutcomesOur goals for student learning were most related to ABET outcomes two through five, especially2 and 4: 2. an ability to apply engineering design to

It is delivered to chemical, biological and environmentalengineers directly following the material and energy balance courses. The goal of the course is tohave students recognize that variation is inevitable, and teach them skills to quantify thevariation and make engineering decisions which account for it while still utilizing model basedproblem solving skills.The instructional design is based on constructivist and social constructivist models of learning. Aconstructivist perspective views learning as individually constructed based on the learner’s priorknowledge, interpretations, and
syllabus states the course objectives in the following words: 1. To help you apply classical thermodynamics (in particular, the first and second laws) to medical devices, laboratory systems, and living systems. 2. To enable you to write and solve macroscopic material and energy balances on laboratory devices and living systems. Such a knowledge will be useful in specifying and applying medical instrumentation, in analyzing existing and proposed medical devices such as artificial organs, and in the study of quantitative physiology and transport in BME 210, 251, 252, and later courses. 3. To provide a forum for solving problems and addressing relevant bioengineering issues in groups.Approaches to
problems for the Material and Energy Balance Course. With continuing funding, fiveadditional core courses have been added: Kinetics and Reactor Design; Process Dynamics andControl; Heat and Mass Transfer; Fluid Dynamics; and Thermodynamics. Workshops were heldfor faculty to learn basic principles of biology and how engineering principles are applied inmany different aspects of modern biotechnology, from kinetics of biological reactions to fluidtransfer and process dynamics problems in whole organisms. Problems are organized bytextbook sections relevant for each course. There are over 300 problems posted on the websiteand the solutions to the problems are available only to registered faculty. The problems havebeen created by chemical engineering
group. Conversely, in upper level courses, wherestudents are more likely to have committed to engineering pathways and have developed effectivecoursework strategies, we see no significant relationship between changes in EI measures and receipt ofpersonalized feedback. This stands in contrast to students in the control group, who in the introductoryChemical Engineering course, had uniformly higher positive EI beliefs by the end of the term. It may bethat students who receive personalized feedback earlier, exit their early courses with higher levels of EI. Table 1.

Twoconstructs were explored: problem solving and perception of problem difficulty. The study adoptedan established and validated rubric to quantify performance in relevant stages of problem solving,including problem identification, representation, organization, calculation, solution completion,and solution accuracy. While problem solving can be influenced by perception of problemdifficulty, the widely used NASA Task Load Index (TLX) was adopted to measure the problemrigor.

The first two years of the program are similar to traditional engineering disciplines.Thereafter, one takes a series of courses that introduce Energy Engineering concepts.Fundamental energy engineering principles involve material and energy balances,thermodynamics, fluid mechanics, heat and mass transfer operations, and physical and chemicalprocessing as applied to energy industries. In addition to these engineering principles, studentsenroll in required courses in renewable/sustainable energy principles. Students will be trained inbasic chemistry of fuels – coal, petroleum, natural gas and biomass; combustion; petroleum andnatural gas processing; electrochemical energy conversion; and energy conversion
successes of collaborative learning, selected elements of each were tied intoa simple project requiring minimal student time to collaboratively develop a reflective learningdocument using a wiki. A wiki is a web-accessible document that can be edited by multipleusers. For this project, students in a material and energy balance course were assigned theweekly task of maintaining a wiki page on the current textbook chapter by entering what theyperceived as the most important items learned during class. This was similar to other activelearning activities suggested in the literature, but in this case the student contributions werecollaborative and archival. Students were encouraged to be complete and accurate with thepromise that their entries would be
