These studentswere given a class assignment to write an essay in which they reflected on the links betweentheir co-op work assignment and their Statics course. The pedagogical purpose of thisassignment was to prompt students to think in depth about the

formulated with several objectives: • Encourage students to reflect on thermodynamic concepts and link them to more concrete applications. • Enable students to communicate thermodynamic concepts using media or methods they felt comfortable with. • Connect more directly with students in a large lecture environment. • Foster a collaborative learning environment in the classrooms as students engaged with other student projects.The specific project described was also intended to address needed pedagogical elements in theclass. Felder et al. has identified several types of learning styles including visual, verbal, sensing,intuitive, global, sequential, and more.10 Felder recommends that engineering instructors focus noton specific

Figure 1: Representation of porous sound absorption materialThe incident wave impacts the face of the material, reflecting some of its energy and sending therest into the material. The energy sent into the material is either transmitted through the material,or absorbed within the porous structure of the material. The sound absorption coefficient is thesum of the percentages of sound that were not reflected. From Figures 1, the sound transmissioncoefficient, τ, is simply the ratio of the sound power transmitted through the material sample intoanother space to the sound power incident on one side of a material sample. Since some soundenergy

However, even the qualitative analysis can be useful. Outcomes2 and 4 seem to be least addressed. The apparent lack of coverage of Outcome 2 is a reflection Page 24.18.5of the fact that Table 1 only includes the analysis problems; significant coverage of this outcomewas provided by traditional homework problems. The limited coverage of Outcome 4 is notsurprising since developing problems that cross traditional boundaries is not easy. This wasexacerbated in 2013 due

many activities that follow the 5E’s approach9, and have done so in a traditional coursedelivery structure. The courses have been well-received by students with a range of class sizesfrom as low as 35 to as large as 54 students each semester. Since this is a required course inengineering at University of PEI, the enrolment reflects the variability in annual cohorts.In its original form, the course-work consisted of in-class quizzes on a topic-by-topic basis. Thequizzes made up 40% of the course grade (5 quizzes throughout the term with a “drop thelowest” policy). 10% of the grade was earned by individual solutions of practice problems. Theremaining 50% of the course grades were earned from extensive lab reports from 5 of 6 labsdone through the

While scrutinizing higher educationwhich has been central to the cultural and technological advancement of civilization solely on amonetary basis might seem irreverent or myopic, the vigorous ongoing debate on education hasundeniably spurred action and innovation.

Page 24.682.3The required courses of the typical engineer offer little room for flexibility. By the junior andsenior years, students are fairly programmed into set schedules. Engineers, then, must beprovided with something that will give them the skills to produce the text needed to survive inthe real world and do it in a manner that requires the least amount of superfluous effort.Supplying large numbers of writing courses will not improve the situation

Theseinclude:  Using the Index of Learning Styles (ILS)4-6 to categorize learning style preferences and tailor information delivery. The ILS is a relatively simple measure of how students prefer to receive information. The survey divides learning style preferences into four domains with opposing descriptors, visual-verbal, active-reflective, sensory-intuitive, and sequential-global. Using these domains, it has been established that students tend to prefer visual, active, and sensory modes, despite the fact

Proper testing facilities should be available to students throughout theproject so that they can learn to operate them, measure attachment points, etc. Materialsand shop facilities must also be made available if prototypes will be required. Andcertainly the projects must be carefully aligned with the desired outcomes.Third, many students struggle to accurately assess the causes for the difference betweentheir theoretical results and what they find during testing. Taking time in class to reflect onthe possible causes is important. For example, we have found that often the students dothe analysis correctly, but fail to take into

objectives for thispaper was to document the details of what we did to implement the flipped classroom, includingdetails such as software choices, video length, and topic used. Here are the things that we learnedand wished that we had known when we started this. 1. Do not be afraid to try new things. When Prof. DeNucci, first brought this idea to Prof. Swithenbank, she was not excited about this. It was new and different, but after further reflection, she thought “why not give it a try?” This may work for you and it may not, but it was definitely worth trying. We would use this method again after trying it while incorporating some of these lessons learned. 2. Preparation will reduce the amount of time it takes to produce the

People with this learning style are best at finding practical uses for ideas and theories.

Continued poor performance inthermodynamics is linked to students not grasping key concepts and failing to recognize how toapply relevant concepts in solving problems.(1) Many students succeed at algorithmic problemsolving yet have difficulty explaining the physical systems being described by the mathematics.This is reflected in low scores on concept inventory exams which require minimal mathematicalcalculations, but are designed around common misconceptions.(2,3)Poor learning has been linked to not being able to correctly assess the information provided andbegins with a lack of clear understanding of the fundamental concepts. A coherent framing ofproblems is essential to reason through new problems.(4) To address this, teachers often

Learning style (also referred to as psychologicaltype6,7) refers to how students preferentially perceive (e.g., sensory vs. intuitive), howinformation is most effectively perceived (e.g., verbally or visually), how information ispreferentially organized (e.g., inductive vs. deductive), how information is processed (e.g.,actively vs. reflectively), and how understanding
