Grading Standards

Course Grade

The final grade for the course will be based on the scores earned in the two mandatory exams, the mandatory comprehensive exam, the average score earned in the quizzes, the average score earned in the homework, and the average score earned in lab reports. Each one of the two exams contributes 10%, the comprehensive exam contributes 15%, quizzes average contributes 20%, homework average contributes 15%, lab reports average contributes 20%, and participation, neatness, attitude, and class attendance contribute 10%, for a total of 100%. The overall average score (X) for the course is determined as follows:

X =0.10 x (exam1 score + exam 2 score) + 0.15 x (Comprehensive exam score) + 0.20 x (quizzes average score) + 0.15 x (homework average score) + 0.20 x (lab report average score) + 0.10 x (participation/neatness/attitude/attendance scores).

Submission Format Policy

Lecture Format

This course consists of a three 50-minutes sessions per week and three lab hours. The three hours class will be spent mostly explaining and discussing concepts, and solving relevant case problems. The other three class hours will be dedicated to a short lecture, lab experiments, result analysis, and lab reports. Lectures will not be used to communicate the entire textbook course content and thus, you will have to study a set of course paragraphs specified by the instructor on your own to further your understanding. Student participation in class discussions is highly encouraged and rewarded.

Exams

There will be two regular exams plus one comprehensive exam at the end of the semester. Each exam is based on two testing parts. A Theoretical part based on chapters reading (closed book) is designed to test the students’ ability to acquire a self-reading knowledge of the taught materials. A practical part (open book) is designed to test the students’ ability to analyze and solve a set of problems. Each exam is based on the course materials developed between two consecutive exams, except for the last one which is comprehensive.

Quizzes

The goal of these quizzes is to encourage the students to study the course materials by themselves. Quizzes will consist of true/false, multiple choice type of questions and/or short problems.

Homework

Homework will be assigned from a set of chosen chapters by the instructor. It will be turned in each week, unless specified by the instructor.

Lab Reports

Lab reports are based on mass and heat transfer theories studied in class, or presented during lab sessions. Labs will be submitted either in formal or informal presentations. All informal labs must be presented with three full paragraphs, theory used, results obtained, and a thorough discussion of the results. A special attention will be dedicated to the presentation. A formal template lab report will be handed out to the students. Students are encouraged to finish their lab and submit it during the lab session if possible. Arriving late to the lab will be penalized by -5 points on the lab grade. Quitting the lab session without the authorization of the instructor will be penalized by -10 points on the lab grade.

Note: You may not submit a paper for a grade in this class that already has been (or will be) submitted for a grade in another course, unless you obtain the explicit written permission of me and the other instructor involved in advance.

Late Paper Policy

Exams

You are expected to take the exam on the scheduled date and time it is given. However, if for a major and acceptable reason you are unable to do so, then you must inform the instructor in advance in writing and give a valid proof of your absence. The instructor will give then a make-up exam toward the end of the semester. For those who did not have a valid reason for missing the exam, they are allowed to take the make-up exam, but they will be graded over 80% of the regular 100% exam grade. The examination materials for the make-up exam may be very different from the ones given in regular exams.

Quizzes

You are expected to take these quizzes on random scheduled dates and times. However, if for a major reason you are unable to do so, then you must provide the instructor with a valid written excuse. For those who missed quizzes with a valid reason, the instructor will then give two make-up quizzes at the end of the semester. For those who did not have a valid reason for missing the quizzes, they are allowed to take the make-up quizzes, but they will be graded over 80% of the regular 100% quiz grade. The examination materials for the make-up quizzes may be very different from the ones given in regular quizzes.

Homework

Homework are turned in each week, unless specified by the instructor. Homework must be turned in on the due date at the beginning of class. Once class starts, homework will be still accepted for a grace period of 48 hours and graded over 80% of the regular 100% homework grade. After the grace period, homework will be accepted and graded over 60% of the regular 100% homework grade. Each student is responsible for submitting his own individual personal homework copy, written in his own words. No dual or group homework copy is accepted unless specified by the instructor.

Lab Reports

Lab reports must be turned in on the due date, at the beginning of class. Once lab class starts, lab reports will be still accepted for a grace period of 48 hours and graded over 80% of the regular 100% lab grade. Once the grace period is over, lab report will be still accepted and graded over 60% of the regular 100% lab grade. THERE IS NO MAKE-UPfor any lab session missed. Each group of students is responsible for submitting its own lab report in its own words. A student cannot add its name to a student lab group if absent.

Plagiarism Policy Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception. Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters. We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student. We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed. Written and adopted by the 2002-2003 MSU Student Senate.

Students with Disabilities The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring an accommodation, please contact the Disability Support Services in Room 168 of the Clark Student Center, 397-4140.

Safe Zones Statement The professor considers this classroom to be a place where you will be treated with respect as a human being - regardless of gender, race, ethnicity, national origin, religious affiliation, sexual orientation, political beliefs, age, or ability. Additionally, diversity of thought is appreciated and encouraged, provided you can agree to disagree. It is the professor's expectation that ALL students consider the classroom a safe environment.
