Student Coursework Requirements

It is expected that each module will take approximately 8–11 hours per week to complete. Here is an approximate breakdown: reading the assigned sections of the texts (approximately 2 hours per week) as well as some outside reading, listening to the audio annotated slide presentations (approximately 2–3 hours per week), and completing assignments and computer solutions (approximately 4–6 hours per week).

This course will comprise four basic student requirements:

1. Preparation and Participation (Module Discussions) (15% of Final Grade Calculation)

There will be module discussion topics posted each week in which there is not a quiz or exam.  The designated module discussion forums will be graded – these graded discussion forums will occur during modules 1, 2, 4, 5, 6, 8, 9, 10, 12 and 13.  You are responsible for carefully reading all assigned material, performing the practice assignment problems, and being prepared for discussion. The majority of readings and practice assignment problems 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 3 for that module week. Posting a response to the discussion question is part one of your grade for the designated module discussion forums (i.e., Timeliness).

Part two of your grade for designated module discussion forums 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.

I will monitor all module discussions and will respond to some of the discussions as they are posted. In some instances, I may summarize the overall discussions and post the summary for the module.

Evaluation of your preparation and participation is based on your contribution to the designated module discussion forums.

Preparation and participation is evaluated by the following grading elements:

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

Preparation and participation is graded as follows:

100–90 = A—Timeliness [participates regularly in all designated discussion forums; all required postings; early in discussion; throughout the discussion]; Critical Thinking [rich in content; full of thoughts, insight, and analysis].

89–80 = B—Timeliness [frequently participates in all designated discussion forums; all required postings; some not in time for others to read and respond]; Critical Thinking [substantial information; thought, insight, and analysis has taken place].

79–70 = C—Timeliness [infrequently participates in all designated discussion forums; all required postings; most at the last minute without allowing for response time]; Critical Thinking [generally competent; information is thin and commonplace].

2. Practice Assignments (20% of Final Grade Calculation)

Practice Assignments will include qualitative questions and quantitative problem sets. 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. Each problem should have the problem statement, assumptions, computations, and conclusions/discussion delineated. All Figures and Tables should be captioned and labeled appropriately.

All Practice Assignments are due according to the dates in the Calendar.

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

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.

Qualitative Practice Assignments are evaluated by the following grading elements:

    1. Each part of the assignment question is answered (20%)
    2. Solution assumptions and rationale are provided and articulated clearly (writing and organization of your solution response is expected to meet or exceed accepted graduate-level English and scholarship standards) (20%)
    3. Solution intermediate results are included (20%)
    4. Technical accuracy of the response / solution (40%)

Qualitative Practice Assignments are graded as follows:

100–90 = A—All parts of question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [rich in content; full of thought, insight, and analysis].

89–80 = B—All parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [substantial information; thought, insight, and analysis has taken place].

79–70=C—Majority of parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [generally competent; information is thin and commonplace].

<70=F—Some parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [rudimentary and superficial; no analysis or insight displayed].

Quantitative Practice Assignments are evaluated by the following grading elements:

    1. Each part of question is answered (25%)
    2. Assumptions are clearly stated (15%)
    3. Intermediate derivations and calculations are provided (25%)
    4. Answer is technically correct and is clearly indicated (25%)
    5. Answer precision and units are appropriate (10%)

Quantitative Practice 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.

3. Quiz[s] (15% of Final Grade Calculation, combined from two quizzes)

Two quizzes will be given.  Quiz #1 will be available in Module 3 and Quiz #2 will be available in Module 11. You will have one week to complete the quizzes and they will be due by 5PM exactly one week from their release. You may use the course text to complete the quizzes.

The quizzes are evaluated by the following grading elements:

    1. Each part of the question is answered (20%)
    2. Solution assumptions and rationale are provided and articulated clearly (writing and organization of your solution response is expected to meet or exceed accepted graduate-level English and scholarship standards) (20%)
    3. Solution intermediate results are included (20%)
    4. Technical accuracy of the response / solution (40%)

Quizzes are graded as follows:

100–90 = A—All parts of question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [rich in content; full of thought, insight, and analysis].

89–80 = B—All parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [substantial information; thought, insight, and analysis has taken place].

79–70 = C—Majority of parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [generally competent; information is thin and commonplace].

4. Exam[s] (50% of Final Grade Calculation, combined from 25% for Midterm and 25% for Final)

A midterm and final exam will be given.  The midterm exam will be available in Module 7 and the final exam will be available in the last Module. You will have one week to complete the exams and they will be due by 5PM exactly one week from their release. You may use the course text to complete the exams.

The exams are evaluated by the following grading elements:

    1. Each part of the question is answered (20%)
    2. Solution assumptions and rationale are provided and articulated clearly (writing and organization of your solution response is expected to meet or exceed accepted graduate-level English and scholarship standards) (20%)
    3. Solution intermediate results are included (20%)
    4. Technical accuracy of the response / solution (40%)

Exams are graded as follows:

100–90 = A—All parts of question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [rich in content; full of thought, insight, and analysis].

89–80 = B—All parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [substantial information; thought, insight, and analysis has taken place].

79–70 = C—Majority of parts of the question are addressed; Assumptions and rationale; Intermediate results / Technical accuracy of the solution [generally competent; information is thin and commonplace].

Grading Policy

Assignments are due according to the dates posted in your 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.

I 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 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.

A breakdown of grading is provided, below.

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.
