Student Coursework Requirements

It is expected that each module will take approximately 5–9 hours per week to complete. Here is an approximate breakdown: reading the assigned sections of the texts (approximately 1–3 hours per week), listening to the audio annotated slide presentations and self-guided multiple-choice questions (approximately 2–3 hours per week), and various homework assignments (approximately 2–3 hours per week; problem sets, guided MATLAB exercises, and literature critiques).

This course will consist of the following basic student requirements:

Forum Discussions (22% of Final Grade Calculation)

Forum discussions are assigned in modules 1, 2, 4, 5, 7-12,14 and will be posted in the Discussions section. You are responsible for carefully reading all assigned material and being prepared for discussion. The majority of readings are from the course text. Additional reading may be assigned to supplement text readings.

Post your initial response to the discussion questions by the evening of day 4 for that module week. Posting a response to the discussion question is part one of your grade for module discussions (i.e., Timeliness).

Part two of your grade for module discussion is your interaction (i.e., responding to classmate postings with thoughtful responses) with at least two classmates (i.e., Critical Thinking). Just posting your response to a discussion question is not sufficient; we want you to interact with your classmates. Be detailed in your postings and in your responses to your classmates' postings. Feel free to agree or disagree with your classmates. Please ensure that your postings are civil and constructive.

We will monitor module discussions and will respond to some of the discussions as discussions are posted.

Evaluation of preparation and participation is based on contribution to discussions.

Preparation and participation is evaluated by the following grading elements:

  1. Timeliness (50%)
  2. Critical Thinking (50%)

The percent of possible credit for each of the 10 assignments will be multiplied by 2% of your total grade, as graded forum discussions make up 20% of the total grade for this course.

Graded assignment (32.5% of Final Grade Calculation)

Graded assignments will be assigned for modules 1-13. Include a cover sheet with your name and assignment identifier (e.g., Module 2, Problem Set). Also include your name and a page number indicator (i.e., page x of y) on each page of your submissions. You may submit am edited word doc, or a scanned/photographed copy of your homework assignment (provided the work is legible). For each problem, please state any assumptions/context/approach upfront before solving the problem. Make sure to show your work using figures and full sentences!

All assignments are due according to the date given in the assignment

Late submissions will be reduced by one letter grade for each week late (no exceptions without prior coordination with the instructors).

Quantitative assignments are evaluated by the following grading elements:

For each problem in the assignment, full credit will need

  1. Each part of question is answered (25%)
  2. Problem assumptions/context/approach are clearly stated (25%)
  3. Intermediate derivations and calculations are provided (30%)
  4. Answer is technically correct and is clearly indicated (20%)

Qualitative assignments are evaluated by the following grading elements:

For each problem in the assignment, full credit will need

  1. Each part of question is answered (25%)
  2. Writing quality and technical accuracy (50%) (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. Rationale for answer is provided (25%)

The percent of possible credit for each of the 13 assignments will be multiplied by 2.5% of your total grade, as graded problem sets make up 32.5% of the total grade for this course.

Literature Critiques (12% of Final Grade Calculation)

Literature critiques are assigned in modules 1, 3, and 6. Students are to be graded on a literature critique of a peer reviewed article of your choice, related to the assigned topic, where a one-page summary document is to be submitted to the Blackboard forum. Students must demonstrate that they read and synthesized the paper themselves.  Pictures can be used and are encouraged to enrich the summary. Include your name and assignment identifier. You must submit a word doc or pdf.

All assignments are due according to the date given in the assignment

Late submissions will be reduced by one letter grade for each week late (no exceptions without prior coordination with the instructors).

Graded written assignments are evaluated by the following grading elements:

For each problem in the assignment, full credit will need

  1. Submit a 500 word summary of their selected peer-reviewed article (50%)
  2. Include an executive summary of the paper, discuss relevancy to the course module, and describe 1-big limitation and 1-big bold next step (50%)

The percent of possible credit for each of the 3 assignments will be multiplied by 4% of your total grade, as graded written assignments make up 12% of the total grade for this course.

Midterm Exam (16% of Final Grade Calculation)

The midterm exam will be available during Module 7 (time agreed upon by class) and will cover theoretical concepts, leveraging in-class examples and problem sets. You will have approximately 36 hours to complete the exam. You may use the course text to complete the exams. The exam will not include problems from the lectures/problem sets in module 7.

The exams are evaluated similarly to the graded problem sets and graded written assignments:

  1. Each part of question is answered (25%)
  2. Problem assumptions/context/approach are clearly stated (25%)
  3. Intermediate derivations and calculations are provided (30%)
  4. Answer is technically correct and is clearly indicated (20%)

Or

  1. Each part of question is answered (25%)
  2. Writing quality and technical accuracy (50%) (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. Rationale for answer is provided (25%)

The percent of possible credit for each problem will be added up then multiplied by 16% of your total grade.

Final literature survey and report (17.5% of Final Grade Calculation)

A course project will be assigned two modules into the course. Students will be required to select a topic (to be submitted and approved by instructor) by module 7 on which they would like to write a literature review and survey paper. The second to last module of class will have 3 associated presentation times where students will be required to present this literature review for 5% of their final grade (to be recorded). The remaining 12.5% of the grade will be based on grading the survey paper, and delivering periodic updates/submissions.  A more detailed rubric will be sent out during the course

Students must develop and submit a 3-5 page paper (12pt Times New Roman, single spaced) that reviews current relevant papers in a field of biomechanics research. Citations must be used and follow MLA.

The paper should include:

  1. Executive summary/abstract (300 words) (15%)
  2. Introduction/motivation (15%)
  3. Sections describing key research and findings in the area of research. This section is to be organized as students best see fit, but should represent the majority of the review paper (25%)
  4. Sections describing key challenges and gaps in the field (25%)
  5. Conclusion (20%)

In addition this final research survey paper, there will be a presentation based on the literature review. The presentation should be 10 minutes long and should contain similar content to the survey paper – an introduction to the topic, an overview of the researchers in that field, a summary of research activities and key findings in the fields, an assessment of key challenges and gaps for future development. 5% of grade will be given based on completing the presentation, as described above.

The percent of possible credit for each portion of the assignment will be added up and multiplied by 17.5% of your total grade

Grading Policy

Assignments are due according to the dates posted in your Blackboard course site. You may check these due dates in the Course Calendar or the Assignments in the corresponding modules. We will post grades no later than 2 modules 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. Consistently 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 module.

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).

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.
