Timing was such that the first item (theAgreement of Cooperation19) was due at the end of the first week of class so that the teams werestarted quickly with a clear, immediately milestone. Feedback was given on these agreements sothat students had all discussed how to deal with conflict, differing work ethic, and how to bestrespect each other’s ideas. The schedule and plan of progress reports were outlined in thesyllabus on the first day of class for the students. The progress reports were: • Team’s Agreement of Cooperation: Outline goals and guidelines of group participation. • Progress Report 1: Introductory description of proposed, novel analytical

the teaching of concepts in an introductory thermodynamics coursethrough video. This generation of students is technology savvy, and regularly communicates bymeans other than face-to-face interactions (e.g. texting). Additionally, the popularity of sites suchas Khan Academy makes the idea of teaching with video difficult to ignore. Thus, we assert thatthere is value in using this media for instruction, and that this media can be leveraged for use in achemical engineering course. During this study, students will be asked to 1) take a conceptdiscussed during class, and articulate it in video media using everyday examples that otherstudents can relate to (autodidactic learning) 2) watch peer-made videos that teach these concepts(peer-to-peer

Second, studentspresent their solutions and justifications to the entire class for discussion and feedback.Third, students’ peers critique their solutions and provide comments. Finally, students aregiven the opportunity to respond to comments and criticisms, and to modify theirsolutions appropriately

benefits of hands-on learning, such asincreased student attention, are widely acclaimed [1-5], there are also benefits to more traditionalteaching styles, such as the ability transmit more information [6], and the instructor is left tryingto determine which pedagogy will be best suited for each topic in a course. As part of an effort todevelop and promulgate hands-on, active learning pedagogies, the authors have undertaken astudy to develop guidelines for lecture versus hands-on, active learning in fluid mechanics andheat transfer.Students in a junior level Chemical Engineering Fluid Mechanics and Heat Transfer course weretaught in a split manner with two sections and one instructor.

Rodriguez and Gayosos12 extended an earlier formalism proposedby Ponton13, also for stead-state processes.Current texts, however, offer a number of starting points that are quite useful. Felder andRousseau1 present and illustrate a degrees of freedom approach wherein they state that: ndf = nunknowns – nindependent equations (1)  where ndf is the number of degrees of freedom, nunknowns is the number of “unknown variables”and nindependent equations is the number of “independent equations” relating the

students were balancing an individual project with a team project, and afinal one at the end-of-semester when only a final team project remained. This three projectstructure, two individual and one team, allowed us to examine both the design experiences andteam effects on student self-efficacy.A wide number of self-efficacy gains suggest that students’ self-efficacy is positively affected byour senior design class. Patterns of self-efficacy gains indicate that there may be a time-dependent variable that affects the development of students’ self-efficacy. A higher number ofobserved self-efficacy gains between surveys 1 and 2 suggests that the steeper learning curveduring the first half of the course may allow for high gains in self-efficacy

student teams work out theirinterpersonal problems only to then be faced with hours of grading lengthy reports. And,although the students only have to complete the work once, for faculty, the cycle repeatsannually.Two years ago, we attended a presentation on gamification in a laboratory course 1. Although theplan used in that paper did not suit us, the idea of adding an element of fun and competition tothe Unit Ops Lab had a certain appeal. We brainstormed ways to incorporate the game conceptand fix some of the small annoyances of teaching the lab courses. The small gamificationaddition was dubbed “Bragging Points”. The idea would be to recognize the students for doingsomething right (that they probably should have been doing anyway) and let them

The engineering textbook is primarily used for defining terms andequations. Additionally, worked examples and homework problems are included in mostengineering textbooks. However, the invention and mass production of the smartphone andsimple access to factual information through Internet search engines, including Google, haschanged how students obtain most of the information found in textbooks [1].

In the process of pyrolysis, biomass is heated to 400-600°C in the absence of oxygen, to produce bio-oil.2 The products formed in the process arechar, oil, tar, water, and fuel gases.

The next two sections, the students select from eight different“mini-projects” on topics such as Artificial Kidney Design(2), Biomass Conversion toFuels and Absorption of Wastewater Contaminants. These “mini- projects” are project-based multi-disciplinary design experiences. The goal is to introduce some basicengineering concepts, as well as guide the students to which type of engineering theyprefer to study(3, 4) .
