Course Pedagogy Importance of Homework: Solving engineering fluids problems is the only way to understand and master the topic. Thus, homework is an important part of this class. Solutions to the homework will be posted soon after the due date and/or given in class. For these reasons, homework submitted after the due date and time will not receive credit. Cooperative Work: You are encouraged to discuss the homework problems with classmates; however, the final work you turn in must be your own. Copying someone else’s work is unacceptable. You are encouraged to help each other understand the concepts and problem solving techniques involved. There is a clear distinction between discussing work and copying someone else’s work. If you simply copy what someone else has done, you are not increasing your understanding of the material. It is very easy to recognize copying. Presentation: Sloppy, untidy submission of work will be penalized for two main reasons. First, it is not the responsibility of the grader to attempt to decipher your solution because it is either hardly readable or disorganized. Second, as a potential professional engineer, it is important that you learn to communicate your work in the most professional manner possible. This includes the presentation of plots, charts, graphs, figures, equations, and short essays. Website: The UVM blackboard will be used primarily for posting assignments, solutions, and information communicated to the class via UVM’s email system.
