Assessment Log of Recent Changes and Improvements. This section contains a running account of course improvements, including the motivation for the changes. Spring 2008. (Lin) Three design-oriented problems were given at the end of the semester. These problems required use of Interactive Thermodynamics (IT) to examine the efficiencies of three different thermodynamic cycles by varying a number of control parameters. Fall 2007. (Stanier, Ratner) Only minor changes in the course relative to fall 2006. New 6th edition of Moran and Shapiro was used for the first time. Students were required to purchase the book with the “WileyPlus” online content feature, and were allowed to purchase the book with optional IT software. A delay in WileyPlus version textbooks, plus a proliferation of ISBN numbers for the text caused confusion for students and the bookstore. WileyPlus was not used except for voluntary practice problems. Two guest lectures were given (Milster Ferman on UIowa Powerplant, Alec Scranton/David Murhammer on Energy and Society; the powerplant tour was expanded to include 144 students). Spring 2007 (Beckermann) Six 15-minute unannounced quizzes were given. An extensive final design problem was given, as well as six open-ended problems from the Moran & Shapiro text, each requiring ~4 pages of written response. Continuation of open-ended problems and quizzes recommended. (Note, in the fall semester, in-class quizzes are not used since the course is offered in two separate sections). Fall 2006. (Stanier, Ratner) Guest lectures were given (Milster Ferman on UIowa Powerplant, Iowa State researcher on biodiesel); the powerplant tour program was continued from Fall 2005. Spring 2006 (Ratner) Course was maintained similar to Fall 2005. Guest lectures and the power plant were again popular and the students were excited about seeing real-world applications of the topics they are studying. Fall 2005. (Ratner, Stanier) Design problem scaled back to two (one writing and research / one calculation-based) relative to fall 2004. Guest lectures introduced. Guest lectures by Milster Ferman (UIowa Powerplant), Bill Eichinger (Atmospheric Thermodynamics), and Jerry Schnoor (Climate Change) to bring more current applications of thermodynamics to the students. Voluntary program of powerplant tours started to followup on high interest level of students in Milster Ferman lecture. A tablet PC was introduced to improve legibility of hand-worked example problems. Elluminate Live software was used to record tutorials on the IT software – so that more students would have access to a detailed problem solving demos using the IT software. Spring 2005 (Beckermann) Fall 2004. (Ratner, Stanier) Minor changes relative to previous semesters. Three “design problems” (involving a mix of outside reading, guided computations, and open ended problem solving) were used in the course, with students selecting from multiple topics to try to interest students from multiple disciplines. Motivation was to bring more realistic problems to the students, and give more choices to interest electrical and biomedical engineering students. 3 Part A. Improvements and Recommendations this Semester. Provide a description of course improvements that have occurred this semester relative to those of previous semester (including the motivation for these changes), and recommended changes for upcoming semesters as needed. SPRING 2008 HIGHLIGHTS We made the best use of consultation hours by emphasizing one-to-one interaction with students, and offered extended office hours during the weeks of examination to help students understand the concepts. The on-line Wiley-Plus supplemental material was not used because it was incomplete. Instead a number of practice problems were handed out in class. Recommended changes for future offerings: Assign more IT and/or design-oriented problems and/or projects. Part B. Quantitative Assessment Results. Quantitative Assessment Results – Self-Assessment Based: 14 students completed the online EASY survey administered by the college of engineering. Each learning goal was assessed using questions as shown in the table and a 1-6 response scale: 6 strongly agree; 5 moderately agree; 4 slightly agree; 3 slightly disagree; 2 moderately disagree; 1 strongly disagree. Mapping scores of 5-6 to mastery; 3-4 to competency; and 1-2 to exposure. Using this metric, the learning goals fall into 2 categories. The first category contains learning goals 15 falling into mastery. Learning goal 6 (software) was in the category of competency. This is consistent with historically low self assessment given around the IT software package, which requires simple command line programming, has some bugs, and can be difficult at times. EASY Survey Questions I learned the definitions and underlying concepts of thermodynamic terms such as system, property, state, phase, process and cycle. I learned about the concepts of energy transfer by heat and work, and energy transformation from one form to another. I learned how to determine properties for pure, simple, compressible substances, and the relations between these properties. I learned the basic laws of classical thermodynamics for closed and open systems. I learned about some important thermodynamic cycles and their applications. I learned to utilize Interactive Thermodynamics software to compute thermodynamic properties and solve thermodynamics problems. I learned to use IT software to vary parameters in a thermodynamic process or cycle to see the effect on the operation of the process/cycle, thus allowing for the design optimization of the process/cycle. Course goals Mean/Median 1 5.43/6.00 3,4 5.36/5.50 2 5.07/5.00 4 5.21/6.00 5 5.36/5.50 6 4.29/4.00 6 4.07/4.00 4 Quantitative Assessment Results – Exam Based: Summary: “E.x-y” denotes “Examination x, problem y”. There were three midterm examinations (x=1, 2, and 3), and one final examination (x=4). The results show good to excellent achievement of the learning goals 1, 2, 3, 4, and 6. The learning goal 5 involving “thermodynamic cycles and their applications” is fairly achieved. This is because there were only four lectures on cycles and applications scheduled after the third examination and before the final examination. Students did not seem to have enough time to fully understand them. Course Learning Goal Exam/IT Problems Assessment 1.
