It has been suggested that engineers don't have a life. I, for one, refuse to believe this. Tell me what else, besides Thermodynamics, interests you. MCEN 2022 THERMODYNAMICS FALL 1998

Philosophy: Thermodynamics is an important course for most engineers, yet it is considered one of the most difficult courses to understand. In fact, many students finish the semester feeling that the course has been a waste of time, completely incomprehensible, and/or downright boring. Therefore, in an attempt to address these points, I have restructured the course in the following manner. On Mondays and Wednesdays, I will present the theory behind the concepts of thermodynamics and address the mathematical and problem solving aspects of the course. This will be done in a traditional, lecture-style fashion. On Friday, the class will meet in the Integrated Teaching and Learning Laboratory, where the session will consist of one or more of the following elements: a 15 minute group quiz; group work sessions where we will work on problems relating to the material in an active learning environment; demonstrations related to thermodynamics; group presentations on hands-on projects that will be assigned later in the semester. Hopefully by combining the academic background with a more hands-on and group-oriented approach, this course will prove to be one of the more rewarding experiences in your engineering career.

General Information:

Homework is due at the beginning of class each Monday. Late homework will not be accepted. However, you will be allowed to drop one assignment Every Thursday evening from 5-8 p.m., there will be a work session where either myself or the TA (or both) will be there to assist you with questions. It is expected that you will have looked at the material previous to this session. You are encouraged to work together on homework if it helps you learn the material. However, see item 7 on this list.
All exams and quizzes are open book, open note.
There will be twelve 15 minute quizzes during the semester; you are allowed to drop two. These quizzes will be held at the beginning of class on most Fridays. You will be allowed to work in groups of no more than three students, and you are encouraged to work in different groups. There will be no make up quizzes given, as you will be allowed to drop two quizzes.
There will be three hour exams given in this course. You will be allowed to drop the lowest of the three exams. There will be no makeup exams given. Please note that the exams are given in the evening. This is to allow for more time. If there is a problem with any of the dates, please let me know by the end of the first week.
Projects will be done in groups of 4 and will entail experimental work, a write-up and a presentation to class. More information about the projects will be forthcoming.
On Wednesday evening from 5-6, if requested, I will give a review of the concepts learned in the previous week. This hour is for you to get help with any of the lecture or book material that you may be having difficulties with. I will review material that is requested by any of the students attending the session. It is not a homework help session.
Please note: Any incident of academic dishonesty will lead to automatic failure of the course. Such incidents include, but are not limited to: using someone else's work as your own, including homework, quizzes and tests; allowing someone else to use your work; using solution manuals to solve problems;
