Student Coursework Requirements

Course Grading

Course grading will consist of three basic categories with all assignment and deliverable submission links and due dates posted in Canvas.

Self-Check Quizzes (5% of final grade calculation)

Each student is responsible for carefully reviewing all course lecture content and readings. Self-Check Quizzes are provided for each module to promote thought about the lecture topic and gauge student understanding.

Participation in other course interactions including, discussions, office hours, and team projects are also important elements to demonstrating understanding and improving the collective learning process.

Problem Sets (35% of final grade calculation; 5% per problem set)

Problem sets will be quantitative in nature and typically aligned with the associated module content. We are all working professionals and have developed a Problem Set submission/late policy that gives you some flexibility while keeping the class on track.

Any 3 of the problem sets may be submitted up to 1 week late without penalty. Additional late problem set submissions will be penalized per the table below. Solution sets will not be released until the late submission deadline, one week after original due date.

• 0 – 3 Problem Sets (of 9): Full Credit
• 4 – 6 Problem Sets: 10% penalty per assignment
• 7 Problem Sets: 20% penalty per assignment

No credit will be given for late submissions once the associated solution set is released (1 week from due date).

Each assignment will have specific point allocations using a partial-credit methodology. Please review the Problem Set Grading Guidance document in the Canvas Course Information module for further details. No credit will be provided for numerical answers without any supporting work.

Course Team Project (60% of Final Grade Calculation)

A course Team Project will be assigned in the first module of the course. Team assignments will be made by the head instructor once all students have completed the Team Assignment Survey. The project deliverables and their associated milestones for submittal are specified in the Team Project Description (TPD) document, including a breakdown of the respective point values for interim and final project deliverables.

Individual student contributions to each deliverable shall be clearly identified using the Team Organization and Responsibilities (TOR) tool provided in the Canvas Team Project Module.

All project deliverables are due according to assignment due dates in Canvas. Exceptions will be granted on a case-by-case basis, contingent upon receiving prior approval from the head instructor.

For Interim Project deliverables, the maximum eligible grade will be reduced by 10% per day late, where the penalty may be specifically assessed against delinquent team (member) components (provided all other components are submitted on time).

For Final Project deliverables and briefings, no materials will be accepted after the due date. In addition, all team members must present their contribution to the project in order to receive individual credit, where alternate pre-recorded methods are acceptable in select cases (contingent upon instructor approval). No credit will be given if a presentation is not delivered on the scheduled date in the course Calendar.

The Team Project grading is designed to reflect both the team and individual student performance. The Team Organization and Responsibilities (TOR) tool, presentation, and team peer review are used to ensure each student's grade represents their contribution to the Team Project.

Expected Workload

The expected student workload has been tailored for this graduate course offering, with the approximate breakdown provided in the table below. Please note that your experience will vary from week-to-week depending on how the material aligns with your engineering background.

Grading Policy

Student assignments are due according to the assignment due dates in Canvas. Problem Set grades will typically be posted within one week after the solution sets are released (the late submission deadline).

Final grades will be determined by the following weighting:

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

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 in the Graduate Programs catalog).

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.

Students with Disabilities - Accommodations and Accessibility

Johns Hopkins University values diversity and inclusion. We are committed to providing welcoming, equitable, and accessible educational experiences for all students. Students with disabilities (including those with psychological conditions, medical conditions and temporary disabilities) can request accommodations for this course by providing an Accommodation Letter issued by Student Disability Services (SDS). Please request accommodations for this course as early as possible to provide time for effective communication and arrangements.

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.
