Courses were developed that focus onmethods to minimize or prevent waste streams from existing chemical plants in the 1990’s. Theeducational

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.

instruction to remotely teach engineering concepts to diverse,underserved communities during the COVID-19 pandemic and beyond.IntroductionBiomaterials are substances that can treat, augment or replace any tissue, organ or function of thebody [1]. At the inception of the modern biomaterials field in the 1940’s, this mostly includedbioinert medical devices and prostheses for cardiovascular and orthopaedic applications [2].Since this time, biomaterials have evolved with the field of tissue engineering, which aims todevelop functional substitutes for damaged tissues [3]. Today, scientists, engineers, andclinicians collaborate to develop a wide range of novel biomaterials that can diagnose and treatnumerous diseases in previously unimaginable ways [4
in most texts ≠ A numerical approach with Microsoft Excel®74 ≠ Excel/VBA based simulation75Trouble SpotsTrouble spots for this course can include: ≠ Students not understanding the physical meaning of the Laplace variable “s”. This will likely remain a mystery. Instead, focus on how conservation laws in the Laplace domain can be arranged to yield key information about process behaviors through parameters like gains and time constants. ≠ Bringing in computing tools too early or too late. Students must understand the how and why before actively developing models with software like Simulink. The appropriate time to introduce them will depend on your curriculum, but probably should be after

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
Collaboration ReflectionSelf-Reflection AssignmentsThe self-evaluation rubric has been incorporated into a junior-level chemical engineeringundergraduate course through self-reflection assignments. Five times during the semester,students were given an essay prompt to identify one or more skills to work on in the followingtwo-week period (first essay) or one-month period (subsequent essays except the last). Studentswere asked to assess their current proficiency level in that skill according to the self-evaluationrubric, describe their goals related to the skill and their plan for improvement, and share progressin the skill(s) if any had been made since the previous essay.

This concept wasfurther developed to include defining team and task, team climate, communication, and reflection(for a detailed description, please see Table 1)23-26.Design competence focused on finding and evaluating variants and recognizing and solvingcomplex design problems. These were further defined as having the ability to discover and designmultiple solutions to a given problem and to effectively evaluate those solutions to determine thebest solution, and having the ability to see the overall picture of a complex design problem, thenbreaking it into smaller, more manageable parts to solve while keeping the overall problem

With hundreds of numeric combinations on many problems, students canrepeat a new version of any question until they compute correct answer(s). With over 100 differentquestions, the most difficult spreadsheet skills can be identified from students’ success. Thenumber of attempts before correct and total attempts will complement the percent correct to givemultiple metrics. Over 9,000 questions were attempted by the 2018 cohort and will be analyzedhere.

substrate-enzyme reaction can be expressed as S + E ←⎯→ k1 ES (1) k2 ES ⎯⎯→ k3 P+E (2) S = Substrate E = Enzyme ES = Enzyme-Substrate Complex P = ProductThe Michaelis-Menten approach was used to derive the rate equation. For this approach, it isassumed that the product-releasing step is much slower than the reversible reaction. Thereversible reaction involves the formation of an enzyme-substrate complex, which is based on avery weak interaction

presented with the followinghomework problem: A tube with circular cross section is fashioned from compacted dark chocolate powder (inner wall radius R = 2 cm, total length L = 20 cm). Warm milk is flowing slowly (v = 6 cm s-1) in laminar fashion (no chaotic mixing) through it. The milk entering the tube is chocolate-free (0.0 g cm-3). Chocolate dissolving in the milk is carried downstream by convection and is also spreading radially inward by diffusion. The diffusion coefficient of the chocolate in the milk is D = 0.35 cm2 s-1. You realize that the system may be described with the following PDE (z is the length down the tube, r is the radius, c is the local concentration of chocolate in
