Explain the process and importance of professional licensure (P5) HELPFUL INFORMATION My Teaching Philosophy: My goal in teaching is to prepare students to become confident and responsible professionals. My approach to teaching involves being a facilitator in the learning process as opposed to being an authoritarian favoring one-way transfer of information. My objectives, therefore, are to understand and respect individual differences in learning and do the best that I can to promote learning in the classroom by working with individual differences rather than against them. At the same time, I wish to impart technical skills and a sense of responsibility by encouraging students to play the role of professionals in the classroom. I expect students to put their best effort in this course. This involves attending class, participating in the in-class exercises, reading the assigned material before attending class, doing the homework, editing the lab reports until they are clear and correct, and preparing for quizzes and exams. 1
Lecture: I will spend approximately 1/3 of lecture time to explain the key concepts of fluid mechanics. The other 2/3 will be devoted to solution of problems. This will change depending on the topics covered but I will follow this as far as possible. You are expected to develop an understanding of other material outside of class. Lectures will help you solve the problems on the quizzes and the final exam. Labs: The laboratory assignments will give you hands-on experience with the science of fluid mechanics and will help reinforce the theory you learn in class. Remember that there is no such thing as an easy experiment (Why?). The lab assignments provide an opportunity for you to work with a physical system (one you can touch and observe) as opposed to a purely abstract system (one you can only imagine). Working with a physical system will help you develop an appreciation of the nature of a fluids and their behavior. Homework: Homework will be assigned to give you some practice using the concepts and procedures discussed in class and in the text. I expect you to do your own homework. Homework is due before 4:30 pm in the main office on the day it is due. Due dates will be posted on your course web page and/or announced using the university e-mail system. You are responsible for checking your e-mail in a timely manner. You will have approximately one week to turn in your completed work from the day the HW problems are assigned. To receive full points, use the following format and directions for your homework: Use standard sized 81/2” x 11” paper. Summarize the given data, identify the unknowns, clearly state all assumptions, include a diagram (where applicable) and show all steps and intermediate results. Do not forget to include units. Present your work in a neat organized manner. Underline critical points and put the final answer in a box. Turn it in by 4:30pm at the CEE office (3500EB). Keep a copy for yourself so that you can compare your solution to the solution we post on the web. Readings: Reading and studying the assigned material is essential to developing sufficient understanding of fluid mechanics to do well in the course. The solved problems and figures are helpful and should be studied carefully. You are expected to read the appropriate sections in your textbook (see schedule below) before coming to class. Quizzes: The seven quizzes (six regular quizzes plus one lab quiz) will test your understanding of fluid mechanics. There will be an emphasis on the numerical solution of word problems similar to the ones solved in class and assigned for homework. There will also be questions to test the understanding you have developed of basic concepts and principles through your study outside of class. All quizzes and the final exam are closed book. You are allowed to bring a cheat sheet with formulas. I will provide all property values and other relevant information. Please remember to bring a calculator. Final Exam: The final exam will cover topics for the entire course. Please note that there are no make-up exams in this course. It is your responsibility to appear in time for the final exam. Study Groups: Study groups, if used correctly, can aid your learning. Use a study group to discuss methods that can be employed to solve a homework problem and when and/or why these methods are appropriate. It is inappropriate and academically dishonest to divide-up a homework assignment (problems) among the members of a group, each person doing a few problems and then copying other peoples answers to problems you did not do. Academic honesty: Copying all, or part, of someone else’s homework, or lab report, or looking at someone else’s quiz or exam during a test period are all obvious forms of academic dishonesty. Anyone found guilty of academic dishonesty will get a 0.0 for the course. For additional 2
information visit the web page of the office of the ombudsman: https://www.msu.edu/unit/ombud/academic-integrity/index.html Grading Scale: The following grading scale will be used. Score Grade Score Grade 91-100 4.0 70-74 2.0 86-90 3.5 65-69 1.5 80-85 3.0 55-64 1.0 75-79 2.5 0-54 0.0 Note the integer point scale. For example, all final scores between 86.0 and 90.99 are a 3.5. A 4.0 requires scores of 91.0 and above and so on. Course Grade: A weighted-score will be computed and the grade determined on the basis of the grading scale indicated. I retain the option to curve the final scores but you should assume that I would not do that. Homework In-class activities/Attendance Six quizzes (best five of six: 5*6=30) Final Exam Laboratory
10 % 10 % 30% 20% 30%
Note that while homework itself is only worth 10%, completing the homework problems and getting actively involved in the exercises provided during lecture will prepare you for the quizzes and the final exam. Attendance and In-class Activities: You are expected to attend all classes. The random in-class activities are designed to test your understanding of key concepts and to ensure that students attend classes regularly. The instructor will assign a maximum of 10 points for in-class activities based on his discretion (after examining all the in-class activities of the student for the entire semester). Assistance: We (the TA and I) are available during our scheduled office hours to help you. You will make the best of your time by having identified specific questions that you need answered before talking to us. Often by identifying the issues you need help with, you will be able to find the answer yourself - a skill worth developing. Syllabus / Important Dates / Class Policies: We will try to follow the schedule shown in the table below. If there are errors in the table (or if we decide to cover some topics in more detail), the dates and topics will change. I will announce these changes in class and an updated version of this document will be posted on your class web page. Similarly in the unlikely event that we need to change some class policies, the latest version of this document will be posted online. It is your responsibility to check the class web page at regular intervals. Course Web Page: Lecture notes and other resources are posted on the course web page. The link to the class web page is: http://www.egr.msu.edu/classes/ce321/mantha/. Lecture notes, HW problems, Instructor and TA office hours and announcements (and any changes to this document) will be posted on the course page. Makeup Exam Policy: There are no makeup exams since we take the best five out of six quizzes. Homework Grading Policy: It is not possible to grade all homework assignments. However, solutions to all homework assignments will be posted online to help you with your work. A few randomly selected HW assignments will be graded and these scores will be used to compute your 3
final grade. However, you should assume that all homework assignments will be graded and used to compute the final grade. Projects. Projects are an important part of this course. They are carefully selected to give you experience in applying the principles of fluid mechanics. Project reports will be evaluated for correctness of the theory, calculations etc. as well as for completeness. Evaluations are evidencebased so if you claim to have done some calculations, it is important that you include those calculations in your report either as an Appendix or in the main body of the report. Once project teams are formed, I have no way of evaluating individual contributions; therefore I assume that you put in your best effort possible. From time to time, I talk to project teams to make sure members are contributing to the final product (the report). Project evaluation forms will also be distributed to all students. If a majority of the members in a team indicate that a certain individual did not substantially contribute to the project, that individual will receive a zero for the project. Therefore it is your responsibility to work with your project team members. If there are differences of opinion on how to divide project tasks or other reasons that make it impossible for you to work with your team, you are responsible for bringing this to my (or the TA’s) attention sooner than later. Policy on use of Phones, Tablets and Computers in the Classroom. Given our subject matter (fluid mechanics) and the nature of our in-class activities that include solving problems of a numerical nature, I have determined that students do not need to access material on the Internet while they are in the classroom. Therefore, the use of cell phones, iPods, iPads / tablets, laptops / other computers and similar devices is not allowed during class hours. Any student using these electronic devices must leave the classroom for the rest of the day. I have arrived at the decision after careful thinking. Please read the attached article on this topic. Computational Thinking: I encourage computational thinking in this course as a way of solving problems and thinking about fluid mechanics and the world of fluids around you in general. What exactly is computational thinking? Do a Google search to learn more or lookup Wikipedia. I encourage the use of MATLAB or Excel as tools that help you with your day-to-day computational tasks and for visualizing data. You are doing computations if you are trying to fit a line or a curve to your data, trying to solve a system of equations involving pipe flows or trying to solve a non-linear equation iteratively for the friction factor based on pipe flow theory. I often say that to be a good driver you don’t need to understand exactly how the fuel injection system works. In a similar way, you can learn to make intelligent use of readily available tools such as MATLAB and Excel even if you don’t understand all the details of the algorithms used inside the functions. I will not be able to teach MATLAB or numerical methods in this course but I expect you to make use of the help system available in MATLAB to learn how to use a function. There are a number of freely available resources on the Internet if you are interested in computational work. I am happy to help you with specific tasks but you need to ask! Happy computing!
