0 1.9 64.0We have had first year students do this lab for the past seven years. We wondered if studentsremembered the technique later, so we asked some questions of sophomore chemical engineeringstudents. During the semester, 38 students in the Material and Energy Balances class were givena homework problem from the textbook8 (problem 4.13, 3rd edition). In this problem, thestudents must perform the same type of analysis as the fermentation lab, finding a regressionequation for exponential data. The students were asked to use Excel to find the equation and alsoto plot the data on a piece of log-log paper. Surprisingly, most of the students had troublecreating the paper plot (but had no trouble with the Excel regression

These coursesdeliver the principles of unit operations theory, the laboratory practices of which are usuallyemployed as a program capstone7. While a foundational Material and Energy Balance (MEB)course is typically the first to introduce students in these programs to the techniques of applyingtransient matter and energy balances, those systems are most commonly treated as spatiallyhomogeneous8,9. Limiting system analysis to a strictly temporal variation ensures that the only asingle ordinary differential equation (ODE), or a system thereof, will arise.The transport courses following MEB focus on fluid mechanics, heat transfer, and masstransfer/separations.

In each of these categories,respondents rated the use from 5 (high) to 1 (low) with an additional option to state ifspreadsheets were not used for this category. In Figure 1 the average score for this rating isshown. To compare this question to the 2003 survey in which only a yes or now response wasobtained, we grouped the 4 and 5 responses to indicate a yes.

EML is an excellent complement to project-based learning,collaborative pedagogies, and other student-centered activities both in and out of class. The KEENframework is summarized in Figure 1.

Second, thestudents were able to make connections between their introductory sciences courses from theirfreshman year curriculum and these process units, effectively bridging the mental gap betweentheir prior coursework and their future chemical engineering courses. Third, the team exercisewas representative of the type of group work and oral presentations required in several chemicalengineering courses. By forming these relationships among the participating students, they couldbegin their sophomore year knowing their classmates and identify potential study partners.

It is important to note that a core class in the CHBE curriculum iscalled “Material and Energy Balances”, and is likely a strong contributor to this difference.The theme “diagrams” also had a significant increase in frequency from the start to the end ofterm from 0 to 15. This theme would be expected to increase since it is the first term thatstudents start interpreting and creating chemical engineering diagrams such as block flowdiagrams and process flow diagrams. Some other themes that had similar trends of high increasebetween start and end are “equilibrium” (1 to 12), “process control” (2 to 21), “reaction ratelaw/kinetics” (3 to 16), and “separation techniques” (0 to 11). All of these topics are

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
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

paper describes theinstructional structure and design of a large sophomore level data analysis and statistics classbased on best educational practices. 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

S. This was the first year of teaching for theinstructor and TAs of the course. The course covers reaction stoichiometry and homogenous kinetics,steady-state and time-dependent reactor design with material and energy balances, deriving reactionmechanisms and rate laws, and understanding transport limitations for heterogeneous catalysis. The coursegrade was comprised of graded homework sets (15%) and 3 midterm exams (16%, 17%, 17
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
