The Tiktaalik Collection: Science in Transformation

This poster, first presented at the National Academy of Engineers Frontiers of Engineering Education workshop in Long Beach CA in Oct 2012, explains the necessity of developing engineering cognition, affection, and conation by completing the whole Kolb Learning Cycle. It emphasizes experience and reflection as essential, but overlooked, aspects engineering education with the potential to create transformation of the student.

This project is developing and testing a new approach to teaching engineering and science students that leverages their interest in experiment and experience. Unlike a traditional liberal arts pedagogy involving reading about ethics, discussing the readings, and writing new analyses, this pedagogy uses games to position students in a series of potentially adversarial relationships that force them to confront some of the salient problems of sustainability, including environmental externalities, the Tragedy of the Commons, weak vs. strong sustainability and intra-generational equity. Recent tests allow students at different universities to play the games simultaneously using information communication technologies (ICT). In each game, students must ask themselves the questions related to moral cognition , "What are my obligations to my fellow students?” and moral conation, “What am I willing to risk in my own sense of well-being to meet these obligations?" We hypothesize that this approach will result in students that are actively engaged in learning exercises, and result in an improved ability to identify ethical problems, pose potential solutions, and participate in group deliberations with regard to moral problems.

Historically, advances in technology have made it possible for modern consumers to perform daily tasks more rapidly and efficiently. In the present technological age, innovation extends to energy conservation. As a typical consumer may be well aware, such innovation often means higher prices. However, in the case of appliances which run on minimal energy, advertisements claim that higher purchase prices will be justified by long-term monetary savings resulting from lower energy bills. This report investigates the veracity of this claim. Generally, the findings in this report are that it depends.

The ENERGY STAR program pioneered by the United State Environmental Protection Agency is a voluntary green-labeling program that helps consumers identify energy-saving appliances. Nevertheless, ENERGY STAR does not indicate to consumers whether a higher purchase price for the efficient appliance will be justified by subsequent energy savings.

There are several variables which may justify spending more for energy conserving appliances. It seems uncommon practice for a consumer to thoroughly evaluate factors which affect their purchase, making it possible to spend more money despite the mindset of saving money. The goal of this report is to identify and evaluate the variables, or varying scenarios, that potentially sway the smart purchase decision in the case of ENERGY STAR refrigerators. Thus, the decision can be tailored to a specific type of individual or household.
The ideal refrigerator for any given consumer depends on the habits and preferences of that consumer including: time value of money preferences, food storage habits, and energy prices. A cash flow diagram is a tool used to depict the monetary gains and losses involved in an investment and will be a practical means to showcase both the initial costs and long-term maintenance costs for either type of refrigerator as influenced by each of the three criteria introduced.

This report uses cash flow diagrams to investigative the sensitivity of a refrigerator purchase option to these three parameters. Graphs are also included which will take the costs shown in the cash flow diagrams and display how many years it will take for the higher initial purchase price of the ENERGY STAR refrigerator to be justified by its lower maintenance costs, called the break-even point. The analysis also involves calculating the net present value, a term used largely in business, for both an ENERGY STAR appliance and a conventional appliance; and involves calculating this net present value, also, as influenced by the different circumstances mentioned.
