Student Coursework Requirements

It is expected that each module will take approximately 10-12 hours per week to complete. Here is an estimated breakdown: listening to the video lectures (3-4 hours per week), participating in the discussion (~1 hour per week), taking the quiz (~15 min per week), completing assignments (3-4 hours per week), and working on research project deliverables (~3 hours per week).

This course will consist of the following basic student requirements:

Preparation: Quizzes (10% of Final Grade Calculation)

Each module will have a short, online quiz that you must complete as part of your grade.  The quizzes are designed to permit you to self-assess your knowledge on the topics that are covered and will help you prepare for the exams.  You are responsible for carefully viewing the video lectures and being prepared for discussion and assignments; the quizzes are a tool to help evaluate your level of preparation.  Students must receive a score of 90% or better on the module quizzes before access will be granted to the assignment for the module.

Participation: Conferences, Discussions (15% of Final Grade Calculation)

Conferences (5% of Final Grade Calculation): Students will be asked to schedule 2 online conferences with the instructor via Zoom—one in the middle of the semester, one at the end.  During the conferences, students will be asked about course material and their research projects.  These conferences also help develop a line of communication with the instructor to foster future interactions.  Instructions on how to schedule and participate in these conferences will be provided by the instructor during the semester. 

Discussions (10% of Final Grade Calculation): You are required to participate in a discussion forum during each module, which includes writing an initial post in response to a discussion prompt AND commenting on postings by two (2) other classmates. Unless otherwise instructed, you will need to 1) post your initial response to the discussion prompt by the end of either day 3 or day 4 of that module week (specific deadline information is posted in each module), following any guidelines posted for that module’s discussion forum; and 2) post your comments on 2 other classmates’ responses by the end of day 7 of that module week.  In your comments to other students, please keep your tone collegial and civil.  It is fine to agree or disagree (or something else entirely), but please do so with professionalism and courtesy.  A great way to frame a comment on someone else’s post is to name something you found interesting or thought-provoking about their post and then ask a follow-up question.  The instructor will monitor module discussions and will respond to discussion threads as needed. Together, your initial posting and your comments on classmates’ postings help to drive an interactive discussion environment in what can otherwise become an isolating online course experience.  Your discussion grade will be broken down equally into timeliness and critical thinking, as follows:

• 100–90 = A—Timeliness [all required postings; early in discussion; engaged throughout the discussion]; Critical Thinking [rich in content; full of thought, insight, and analysis; used references where required and appropriate]
• 89–80 = B—Timeliness [all required postings; some not in time for others to read and respond]; Critical Thinking [substantial information; thought, insight, and analysis has taken place; used references where required and appropriate]
• 79–70 = C—Timeliness [all required postings but at the last minute without allowing for response time]; Critical Thinking [generally competent; information is thin and commonplace; poor or no references]
• <70 = F—Timeliness [some or all required postings missing]; Critical Thinking [no references; rudimentary and superficial; no analysis or insight is displayed]

Late policy for discussions: Discussions are the only formal opportunity for students to interact with each other in a semi-synchronous manner; late postings or comments miss the time window when other students will be tuned in and ready to exchange ideas.  Accordingly, there will be a 10% deduction for each day that an initial post is late; any discussion components that are posted after the end of day 7 of a given module will not receive any credit.  At the end of the semester, the lowest discussion grade will be dropped before calculation of the final course grade.

Assignments (25% of Final Grade Calculation)

Assignments for each module will include a mix of qualitative assignments (e.g. essay questions, case study analysis, etc.) and quantitative problem sets.  Each problem should have all relevant assumptions, calculations, and conclusions clearly delineated. All figures and tables should be captioned and labeled appropriately. Assignments must be submitted in PDF format. Unless otherwise indicated, each assignment is due by 11:59 p.m. (Eastern time) on day 7 of the module.  On each assignment submission, your words & work must be your own.  Any violations will be treated as a breach of academic integrity.

Late policy for assignments: If an assignment is submitted late, it will receive a late penalty of 1 letter grade (10%) deduction for each week late, up to 2 weeks late.  Any assignments submitted more than 2 weeks late will receive a zero (0) grade.  At the end of the semester, the lowest assignment grade will be dropped before calculation of the final course grade.

Qualitative assignments are evaluated by the following grading elements:

• Each part of question is answered (20% of each assignment)
• Writing quality and technical accuracy (20% of each assignment). 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.
• Rationale for answer is provided (20% of each assignment)
• Examples are included to illustrate rationale (20% of each assignment)
• Outside references are included, where applicable (20% of each assignment)

Qualitative assignments are graded as follows:

• 100–90 = A—all parts of question are addressed; writing quality/rationale/examples/ outside references [rich in content; full of thought, insight, and analysis].
• 89–80 = B—all parts of the question are addressed; writing quality/rationale/examples/ outside references [substantial information; thought, insight, and analysis has occurred].
• 79–70=C—majority of parts of the question are addressed; writing quality/rationale/ examples/outside references [generally competent; information is thin/commonplace].
• <70=F—some parts of the question are addressed; writing quality/rationale/examples/ outside references [rudimentary and superficial; no analysis or insight displayed].

Quantitative assignments are evaluated by the following grading elements:

• Each part of question is answered (20% of each assignment)
• Assumptions are clearly stated (20% of each assignment)
• Intermediate derivations and calculations are provided (25% of each assignment)
• Answer is technically correct and is clearly indicated (25% of each assignment)
• Answer precision and units are appropriate (10% of each assignment)

Quantitative assignments are graded as follows:

• 100–90 = A—all parts of question are addressed; all assumptions are clearly stated; all intermediate derivations and calculations are provided; answer is technically correct and is clearly indicated; answer precision and units are appropriate.
• 89–80 = B—all parts of question are addressed; all assumptions are clearly stated; some intermediate derivations and calculations are provided; answer is technically correct and is indicated; answer precision and units are appropriate.
• 79–70=C—most parts of question are addressed; assumptions are partially stated; few intermediate derivations and calculations are provided; answer is not technically correct but is indicated; answer precision and units are indicated but inappropriate.
• <70=F—some parts of the question are addressed; assumptions are not stated; intermediate derivations and calculations are not provided; the answer is incorrect or missing; the answer precision and units are inappropriate or missing.

Research Project (35% of Final Grade Calculation)

Each student will complete a semester-long research project designed to help familiarize students with engineering interventions in cardiovascular science and medicine.  It will include a series of written assignments over the course of the semester that build on each other and will culminate in an oral presentation that summarizes their work over the course of the semester and includes a proposal for future design development to better meet current needs.

For specific research assignments, expectations, grading criteria, and formatting requirements, please consult the weekly research project instructions (posted in each module) and the “Course Project” overview document posted on Canvas.  However, for a brief overview, each project component will be evaluated by the following grading elements:

• Each element of the research assignment is addressed (40% of each assignment)
• Writing quality and technical accuracy (40% of each assignment). 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.
• Appropriate outside references are included (10% of each assignment)
• Page limits are adhered to (10% of each assignment)

Course Project is graded as follows:

• 100–90 = A—all aspects of prompt are addressed; writing adheres to page limits; appropriate references are cited; exceptional writing quality/clarity/rationale/examples [rich in content; full of thought, insight, and analysis].
• 89–80 = B—all aspects of the prompt are addressed; writing mostly adheres to page limits; appropriate references are cited; good writing quality/clarity/rationale/examples [substantial thought, insight, and analysis has occurred].
• 79–70=C—most aspects of the prompt are addressed; writing does not adhere to page limits; appropriate references are sometimes cited; average writing quality/clarity rationale/examples [generally competent; information is thin/commonplace].
• <70=F—some aspects of the prompt are addressed; writing does not adhere to page limits; references are seldom or never cited; poor writing quality/clarity/rationale/examples [rudimentary and superficial; little or no thought, insight, or analysis is demonstrated].

The grades from all submitted deliverables will cumulatively account for 35% of the Final Grade Calculation.  Research deliverables must be submitted in PDF format.  Although these are research projects and thus involve reading other people’s writing, your words & work must be your own.  Any violations will be treated as a breach of academic integrity.

Exams (15% of Final Grade Calculation, average of 2 exams)

You will take 2 exams in this course.  The midterm covers material from Modules 1-6 and will be administered in Module 7, and the final exam covers material from Modules 8-13 and will be administered in Module 14. Each exam will be made available in Canvas to students from day 4 to day 7 of the exam module.  You will have 2 hours to complete each exam, which will consist of a combination of objective questions (multiple choice, matching, etc.) and problem-solving/short answer questions.  Additional details about each exam will be provided closer to the exam date.  You must not receive any outside help on any of the exams, and your words & work must be your own.  Any violations will be treated as a breach of academic integrity. 

Exams are evaluated by the following grading elements:

• Each part of question is answered (10%)
• Assumptions are clearly stated (20%)
• Intermediate derivations and calculations are provided (25%)
• Answer is technically correct and is clearly indicated (25%)
• Answer precision and units are appropriate (10%)
• Outside references are included, if required (10%)

Exams are graded as follows:

• 100–90 = A—all parts of question are addressed; all assumptions are clearly stated; all intermediate derivations and calculations are provided; answer is technically correct and is clearly indicated; answer precision and units are appropriate.
• 89–80 = B—all parts of question are addressed; all assumptions are clearly stated; some intermediate derivations and calculations are provided; answer is technically correct and is indicated; answer precision and units are appropriate.
• 79–70=C—most parts of question are addressed; assumptions are partially stated; few intermediate derivations and calculations are provided; answer is not technically correct but is indicated; answer precision and units are indicated but inappropriate.
• <70=F—some parts of the question are addressed; assumptions are not stated; intermediate derivations and calculations are not provided; the answer is incorrect or missing; the answer precision and units are inappropriate or missing.

Grading Policy

Final course grades will be determined by the following weighting:

• Preparation (quizzes) = 10%
• Participation = 15% (conferences 5% + discussions 10%)
• Assignments = 25%
• Exams = 15% (midterm 7.5% + final exam 7.5%)
• Research project = 35%

A grade of “A” indicates achievement of consistent excellence and distinction throughout the course. 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.

Course Evaluation

The link to the course evaluation will be sent out by the university (via email) near the end of the semester.  The instructor will provide more instructions at the end of the semester and answer any questions about accessibility that may arise.

Academic Policies

Deadlines for Adding, Dropping and Withdrawing from Courses

Students may add a course up to one week after the start of the term for that particular course. Students may drop courses according to the drop deadlines outlined in the EP academic calendar (https://ep.jhu.edu/student-services/academic-calendar/). Between the 6th week of the class and prior to the final withdrawal deadline, a student may withdraw from a course with a W on their academic record. A record of the course will remain on the academic record with a W appearing in the grade column to indicate that the student registered and withdrew from the course.

Academic Misconduct Policy

All students are required to read, know, and comply with the Johns Hopkins University Krieger School of Arts and Sciences (KSAS) / Whiting School of Engineering (WSE) Procedures for Handling Allegations of Misconduct by Full-Time and Part-Time Graduate Students.

This policy prohibits academic misconduct, including but not limited to the following: cheating or facilitating cheating; plagiarism; reuse of assignments; unauthorized collaboration; alteration of graded assignments; and unfair competition. Course materials (old assignments, texts, or examinations, etc.) should not be shared unless authorized by the course instructor. Any questions related to this policy should be directed to EP’s academic integrity officer at ep-academic-integrity@jhu.edu.

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.
