Student Coursework Requirements

It is expected that each module will take approximately 6–10 hours per week to complete. Here is an approximate breakdown: reading the assigned sections of the texts (approximately 2–3 hours per week) as well as some outside reading, listening to the audio annotated slide presentations (approximately 2–3 hours per week), and writing assignments (approximately 2–4 hours per week).

This course will consist of the following basic student requirements:

Informed Discussion Board Participation (15% of Final Grade Calculation)

We are going to have 15 discussions. We will have 14 discussions called “Muddiest Points of Module N” where N is the module number. We have 14 modules. Each “Muddiest Points of Module N” has 1% of final grade. Plus 1% for the last discussion “Tell me about yourself and what you get from our course!”.

For the Every “Muddiest Points of Module N” discussion, we will discuss the materials of the Nth module. This “Muddiest Points of Module N” discussion is a sort of an Online Study Group. In each week, you are asked to participate in a discussion on muddiest points. What was the “muddiest point” (i.e., the point that you struggled with the most, or had the most difficulty understanding) for you among the topics and concepts covered throughout this module? How did you resolve the issues you faced in comprehending the topic/concept? If you are still having difficulty with a topic/concept, please elaborate so that I and/or your classmates can assist you.

Each student should make a minimum of two posts. The initial post will answer the question on what was most unclear or "muddiest" and you should also respond to at least one of your peers to try to help clarify their muddiest point. Feel free to post as many questions or comments as you like.

I will monitor module informed discussions and will respond to some. In certain instances, I will summarize the overall discussions and post the summary for the module.

Individual Homework and Reports (20% of Final Grade Calculation)

There will be ten individual homework and reports (2% each of final grade calculation) that will include Part 1 (numerical problems). Some of the assignments will include Part 2 (writing reports and/or programming). You must include a cover sheet with your name and assignment identifier. Also include your name and a page number indicator (i.e., page x of y) on each page of your submissions. All Figures and Tables should be captioned and labeled appropriately.

All assignments are due according to the dates on the Calendar. Late submissions will be reduced by one letter grade for each week late (no exceptions without prior coordination with the instructor). If, after submitting a written assignment you are not satisfied with the grade received, you are encouraged to redo the assignment and resubmit it. If the resubmission results in a better grade, that grade will be substituted for the previous grade.

Part 1 (Numerical Problems) will be evaluated by the following grading elements:

1. Givens and requirements are clearly stated (10% of the assignment Part 1 grade)
2. Sketches are clear and describe the problem (15% of the assignment Part 1 grade)
3. Assumptions are clearly stated (15% of the assignment Part 1 grade)
4. Intermediate derivations and calculations are provided (20% of the assignment Part 1 grade)
5. Answer is technically correct and is clearly indicated plus any needed comments (30% of the assignment Part 1 grade)
6. Precision and units are appropriate (10% of the assignment Part 1 grade)

Part 1 is graded as follows:

• 100–90 = A—All parts of question are addressed; All givens, requirements and assumptions are clearly stated; Sketches are clear and describe the problem. All intermediate derivations and calculations are provided; Answer is technically correct and is clearly indicated; Answer precision and units are appropriate. Comments clearly explain the physical understanding of the problem.
• 89–80 = B—All parts of question are addressed; All assumptions are clearly stated; Sketches are clear and describing the problem; Some intermediate derivations and calculations are provided; Answer is technically correct and is indicated; Answer precision and units are appropriate. Comments explain the physical understanding of the problem.
• 79–70 = C—Most parts of question are addressed; Given, requirements and assumptions are partially stated; Sketches are partially describing the problem Few intermediate derivations and calculations are provided; Answer is not technically correct but is indicated; Answer precision and units are indicated but inappropriate. Comments are stated but the physical explanation is not clear.

Part 2 (Reports and/or Programming) will be evaluated by the following grading elements:

Report with programming:

1. Flow chart or pseudo code of your program with a 10% of the assignment Part 2 grade.
2. The MATLAB program submitted as an “*.m” file with a 60% of the assignment Part 2 grade. Comments and units inside the code are a must.
3. Accuracy and correctness of the results with 30% of the assignment Part 2 grade.

Report only:

1. Follow the standard sequence: Abstract, Introduction, Discussion (or any appropriate subtitle), Conclusion and References (30% of the assignment Part2 grade). Following the sequence and guidelines inside the textbook, A Guide to Writing as an Engineer, is recommended.
2. Writing quality and technical accuracy (40% of the assignment Part2 grade) (Writing is expected to meet or exceed accepted graduate-level English and scholarship standards. That is, all assignments will be graded on grammar and style as well as content.)
3. A 5 min short video where you present your report (30% of the assignment Part2 grade). Your video will be shared with the entire class as part of the discussion.

 Part 2 is graded as follows:

• 100–90 = A—Rich in content; full of thought, insight, and analysis.
• 89–80 = B—Substantial information; thought, insight, and analysis has taken place.
• 79–70 = C—Generally competent; information is thin and commonplace.

Group Final Project (15% of Final Grade Calculation)

In the middle of the semester by the end of module 7, the entire class will be divided into groups.  A group final project, "Flow Over Airfoil ANSYS Fluent CFD Modeling and Simulation,” will be due at the end of the semester (module 14). You must complete two forms: a peer-evaluation and a team-evaluation.

A video presentation is required plus a written report and simulation model. An 80% of the project grade coming from the instructor and 20% of the project grade coming from your peer-reviewers (your classmates, excluding your teammates).

Peer Reviewers Evaluation: After the due date, I will post the video presentations and the written reports on Canvas for discussion and comments (Q&A session). In the peer-evaluation, you must review each video and written paper from the other teams. If you do not complete the peer-evaluation or write a non-insightful evaluation, you will lose 10% of the project grade.

Teammates’ Evaluation: Your grade will be multiplied by a factor x, where x is your teammates’ evaluation score for you. You must complete a team-evaluation form. If you do not complete the team-evaluation or you write a non-insightful evaluation, you will lose 50% of your final group project's grade.

The instructor project evaluation (80% of the project grade) has following grading elements:

1. Video and presentation will be graded as described in the rubric (30% of the project grade).
2. Written report must follow the standard sequence as: Abstract, Introduction, Discussion (or any appropriate subtitles), Conclusion and References (10% of the project grade). Following the sequence and guidelines inside the textbook, A Guide to Writing as an Engineer, is recommended.
3. Writing quality and technical accuracy (10% of the project grade) (Writing is expected to meet or exceed accepted graduate-level English and scholarship standards. That is, all assignments will be graded on grammar and style as well as content.)
4. Flow chart or pseudo code of your program or software (10% of the project grade)
5. A working software or a workable model (20% of the project grade)

Course Project is graded as follows:

• 100–90 = A—rich in content; full of thought, insight, and analysis.
• 89–80 = B—substantial information; thought, insight, and analysis has taken place.
• 79–70 = C—generally competent; information is thin and commonplace.

Exams (50% of Final Grade Calculation: 15% for Midterm and 15% for Final)

The midterm exam will be available in Module 6. The final exam will be available in Module 12. For each exam, you can login anytime during the exam week.  Once you access the exam, you will have 6 days to complete and upload your solution back on Canvas. The two exams will be open book and notes. The two exams are due according to the dates on the Calendar. Late submissions for any exam will not be accepted unless there is an acceptable excuse. 

Grading Policy

Assignments are due according to the dates posted on the Canvas course site. You may check these due dates in the course Calendar or the Assignments in the corresponding modules. I will post grades one week after assignment due dates.

We generally do not directly grade spelling and grammar. However, egregious violations of the rules of the English language will be noted without comment. Consistent poor performance in either spelling or grammar is taken as an indication of poor written communication ability that may detract from your grade.

A grade of A indicates achievement of consistent excellence and distinction throughout the course—that is, conspicuous excellence in all aspects of assignments and discussion in every week.

A grade of B indicates work that meets all course requirements on a level appropriate for graduate academic work. These criteria apply to both undergraduates and graduate students taking the course.

EP uses a +/- grading system (see “Grading System”, Graduate Programs catalog, p. 10).

100-98 = A+97-94 = A93-90 = A−89-87 = B+86-83 = B82-80 = B−79-77 = C+76-73 = C72-70 = C−69-67 = D+66-63 = D

Final grades will be determined by the following weighting:

Classroom Climate

JHU is committed to creating a classroom environment that values the diversity of experiences and perspectives that all students bring. Everyone has the right to be treated with dignity and respect. Fostering an inclusive climate is important. Research and experience show that students who interact with peers who are different from themselves learn new things and experience tangible educational outcomes. At no time in this learning process should someone be singled out or treated unequally on the basis of any seen or unseen part of their identity. 
 
If you have concerns in this course about harassment, discrimination, or any unequal treatment, or if you seek accommodations or resources, please reach out to the course instructor directly. Reporting will never impact your course grade. You may also share concerns with your program chair, the Assistant Dean for Diversity and Inclusion, or the Office of Institutional Equity. In handling reports, people will protect your privacy as much as possible, but faculty and staff are required to officially report information for some cases (e.g. sexual harassment).

Course Auditing

When a student enrolls in an EP course with “audit” status, the student must reach an understanding with the instructor as to what is required to earn the “audit.” If the student does not meet those expectations, the instructor must notify the EP Registration Team [EP-Registration@exchange.johnshopkins.edu] in order for the student to be retroactively dropped or withdrawn from the course (depending on when the "audit" was requested and in accordance with EP registration deadlines). All lecture content will remain accessible to auditing students, but access to all other course material is left to the discretion of the instructor.
