ethics important for chemical engineers? A variety of reasons havebeen posed, including but not limited to enhanced awareness on proper mitigation methods ofhazards and ensuring up and coming engineers understand their responsibilities when faced withadverse situations. By definition, process safety is a discipline that focuses on the prevention offires, explosions, and accidental chemical releases at chemical process facilities [1]. Processsafety provides the means for engineers to understand the risks they are taking to developmechanisms that make those situations inherently safer for all involved. Whether it is at thebench scale or manufacturing level, understanding hazards is crucial at all phases of a process.In the same respect, ethical

They aresignificantly different from those in a typical transport phenomena course, which include theability to identify, simplify and solve differential equations used to describe transport phenomenaand recognize and use the similarities between the theoretical models for momentum, heat andmass transport. Student learning in both courses is assessed via weekly homework assignments,one or two midterm exams and a final exam. In the applied course, however, the “artificial”exam questions were not always a good indication of student learning. Writing exam

The formal researchquestions guiding this work are: 1. What types of process safety ethical dilemmas are the most difficult for students to determine a course of action? 2. How does course instruction in process safety affect decision making approaches?MethodsStudy Design and Data CollectionDuring the 2019 spring semester, the Engineering Process Safety Research Instrument (EPSRI)was distributed to 274 senior chemical engineering students from eight ABET-accreditedinstitutions; the breakdown by institution is shown in Table 1.

While all types of active learning show greater improvements compared to passive learning,interactive engagement, where students are interacting with each other or technology shows thelargest learning gains [1]. Our hands-on team-based learning is inherently interactive, due tostudents working within groups, and we hypothesize that this pedagogy will also demonstratelarger learning gains compared to traditional lectures or students working on the DLMs bythemselves.Often, engineering students do not get to interact with technology or do experiments related toconcepts they are learning until their junior or senior year in
knowledge without first having to introduce significant amounts of background content.This workshop affirms the problem-based motivations of engineering students while providingrelevant connections to the chemical engineering discipline, forming an essential bridge for first-year undergraduates.IntroductionThe first year of undergraduate engineering education is a unique time of transition, opportunity,and expectation for learners. Therefore, it merits intentional design of learning experiences byengineering educators. Adopting a constructivist view of learning, where new knowledge is builtas new experiences lead to the restructuring of previous knowledge [1], it is worthwhile to beginby considering plausible knowledge and skill backgrounds of

While an instructor can’t“intrinsically motivate” students, they certainly can create conditions that cultivate or defeatintrinsic motivation. In this study, the impact on students’ motivational state of five coursedesign features was measured using Guay, Vallerand, and Blanchard’s Situational MotivationScale (SIMS) (1).

The aims of this paper are to shed light on the perceptions of early career faculty(untenured or recently tenured) regarding the tenure process. Specifically, we aim to: (1) classifythe variability in perceptions of tenure requirements among assistant and associate professors inchemical engineering programs and (2) identify their perceived impediments towards obtainingtenure. Faculty from ABET accredited programs in tenure-track positions were identifiedthrough an online search, and were provided with an online survey to complete.

Environmental regulations, strict quality requirements and the constant drive toincrease manpower productivity reinforce this trend; processes without modern automation donot survive. The displacement of the middle skill worker, who in the process industry was thefloor operator responsible for one unit operation, has been happening gradually over the last 3-4decades, replaced by a control room operator who interacts with a control system operating manyunits. Implicitly this has transferred the responsibility for control of units and processes from theoperations staff to the engineering staff. An engineer wishing to build

Withsuch a variety of resources available, and many of them providing tips for spending the time usedto prepare to teach as efficiently as possible, it can be overwhelming for new assistant professorsto find the resources that work best for them.Over the past ten years, the number of tenure-track faculty members in chemical

Two activities have been undertaken at Oregon State University (OSU) insupport of this goal: (1) development of a Nanotechnology Processes Option in the ChemicalEngineering (ChE) Department and (2) development a survey course within the College ofEngineering (CoE) that is broadly available to all engineering undergraduates.

This example illustrates how scaling analysis can beused to both interpret performance data as well as to extract useful characterization parametersfrom the data. As such, it underscores the advantages of scaling analysis as a learning tool tohone students’ intuition.1.

IntroductionThe purpose of this paper is to describe a series of process hazards and risk analysis check sheetsthat were incorporated into a section of an undergraduate chemical engineering laboratorycourse. These new laboratory check sheets provide the students with an approach and tool foranalyzing and documenting risks to ensure that they will safely handle hazardous materials andmanage hazardous processes. The check sheets were developed from work that is required forhigh-risk industrial hazardous processes regulated under the OSHA Process Safety Management(PSM) standard 1910.119.1 They capture and document the qualitative elements of the
