For example, we model a spectrophotometer in one simulation, depicted in Figure 1,where students are able to alter the chemical species, concentration, light intensity, wavelength,and so on. Students are tasked with determining unknown reaction rate constants; in order to doso, they must calibrate the spectrophotometer, set reasonable starting concentrations, run thesimulation for sufficient time, and then use the resulting data to determine the reaction rateconstant. However, the steps required to successfully solve for an unknown property can often beaccomplished in a variety of ways, similar to laboratory experimentation; the simulations areopen-ended, allowing

/community, breakingthe ice with the students is usually not an issue.A common request is for university students and industry alumni to represent their particularengineering disciplines and to break down into stations with 1-2 ambassadors per discipline(sometimes even with a poster or other backdrop prepared ahead of time). Then high schoolstudents spend time at each of their top stations, corresponding to their career leanings. After 5-7minutes, they are instructed to ‘switch stations’. Bringing a demo, or actual representativeoutput of a project creates interest and focuses audience attention.As far as reaching the greatest number of high school students, the best venue is during theschool day, during one or more class sessions.

framework for theteaching and learning process based on a concept familiar to most engineers: feedback controlsystems. Feedback control has long been a staple of engineering curricula, primarily in electricalengineering, but also across other disciplines such as mechanical and chemical engineering. Thisis largely due to the diversity of applications of control theory.[1] Feedback control concepts havealso been applied in areas outside of engineering, such as psychology and human behavior,particularly in the areas of goal setting and performance.[2,3] However, in the field of engineeringeducation, the concepts from control theory have been underused. We build upon the ideaspresented in the related literature by providing a novel control systems

While this approachspecifies in advance the issues and questions to be discussed, it gives the interviewer freedom todecide on the sequence and wording of the questions during the course of the interview.Advantages to this approach are that it provides a systematic and comprehensive way to collectdata while allowing the interview to have a conversational tone and flow11.

written, distributable articulation of suchpriorities is also felt to be required. But if we are interested in the social relations associatedwith engineering codes of ethics, we must ask: Why precisely is such an articulation felt to benecessary? After all, many features of many professional operations never find such formalexpression; although Codes of Ethics for History professors exist, they are rarely invoked inpractice or passed along for graduate students, for example. Moreover, although developing acode of ethics is commonly viewed as having been an essential part of engineering’sprofessionalization in the United States,1 the question of how codes of ethics actually shape dailyengineering practice is a, huge realm for study.

In this case, the 3Dprinter was left unattended overnight since the time predicted by the 3D-printing program tocreate a part was about 9 hours. As the first few layers were deposited, they separated from theprinting platform and adhered to the printing nozzle of the extruder. Then, the nozzle and someportions of the extruder were encapsulated as more plastic was extruded. To remove the plasticbuild-up, a student used a heat gun to re-melt the plastic and release the extruder.
