hydrogels for oral drug delivery. For this experiment, studentsprepare pH-responsive hydrogels based on p(MMA-EG) and characterize the network structureof the swollen hydrogel through mesh size modeling in different pH environments. Students canoptimize the hydrogel for oral drug delivery by varying its structure. They identify importantdesign variables, practice translating quantitative laboratory measurements into data used indesign evaluation, and learn aspects of polymer characterization, which can be applied to otherareas of material science and engineering.Mesh size is determined from correlations using existing tensile and experimental density data tocharacterize how the gels respond to pH variations.The swelling ratio, Q is found from

For each action the highest percentage of responses occurred forthe same consideration with the only exceptions being actions “P” (Working in groups on web-based quizzes) and “Q” (Working in groups on take-home exams). In the survey by 4, the highestpercentage for the consideration of both actions was “Cheating”, while in the current study, thestudents considered action “P” to be “Unethical but not cheating” and action “Q” to be “NeitherUnethical nor cheating”. Regarding the frequency of cheating behavior the only difference in theoccurrence of the highest percentage was for action “C” (Asking another student about questionson an exam you have not taken).

semester. As a reminder, the heat transfer cannotbe directly determined from a P-V diagram. This part of the task requires students to use the FirstLaw, ∆U = Q − W , and knowledge of the work and internal energy comparisons from the othersections of the task. We have also created a one-dimensional work task (see Fig. 2) appropriate for students in ourintroductory courses. In this task, students compare the net work done in propelling a cart the samedistance using two different propulsion methods. We have also altered the phrasing from a questionto a statement. This task differs in two main ways from the P-V task. First, the variables aren’tstate variables. We would need to use tension and extension to get the equivalent one-dimensionaltask and

Differences between the two calculated average detention time valuescould then be used as the focal point for an error analysis.The same basic sensor and overflow system can be used to examine other, more complexexperimental systems with the possible intent of comparing actual and theoretical system tracerresponses, determining the system dispersion number, or estimating the extent of dead volumepresent in a system.
