Environmental Engineering
Summer 2023

Description

This course examines current applications of biotechnology to environmental quality evaluation, monitoring, remediation, and mitigation of contaminated environments. The scale of technology ranges from the molecular to macrobiotic. Relevant topics of microbiology and plant biology are presented. These provide a foundation for following discussions of microbial removal and degradation of organics, phytoremediation of soil and water contaminated with toxic metals and radionuclides, wetlands as treatment processes, biofilms/biofilters for vapor-phase wastes, and composting in alignment with sustainable development goals considering climate change. Emphasis is placed on modeling and design. Advantages and disadvantages of each application are compared. Case studies are presented in the areas of biosensors in environmental analysis, molecular biology applications in environmental engineering, and genetic engineering of organisms for bioremediation. Prerequisites: Prior coursework in environmental microbiology, molecular Biology, or biochemical engineering is recommended but not required.

Student Coursework Requirements

It is expected that each module will take approximately 4–7 hours per week to complete. Here is an approximate breakdown: reading the assigned sections of the texts or assigned journal articles (approximately 2–3 hours per week), listening to the audio annotated slide presentations, and assigned videos and pod casts (approximately 1–2 hours per week), and self-assessment quizzes, problem sets and writing assignments (approximately 1–2 hours per week). 

This course will consist of five basic student requirements: 

  1. Preparation and Participation (Module Discussions) (15% of Final Grade Calculation) 
  2. Quizzes (10% of Final Grade Calculation) 
  3. Written Assignments and Problem Sets (15% of Final Grade Calculation) 
  4. Technical Research Presentation Project (35% of Final Grade Calculation) 
  5. Midterm Exam (20% of Final Grade Calculation) 

Discussion (15% of Final Grade Calculation)

Preparation and Participation emphasis on module discussions- Each module will contain assigned material. Students should prepare for discussion. student are responsible for carefully reading all assigned material and being prepared for discussion and post their 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 the grade for module discussions (i.e., Timeliness). Part two of the grade for module discussion is students’ interaction (i.e., responding to classmate postings with thoughtful responses) with at least two classmates (i.e., Critical Thinking). Weekly assignments will vary depending on module learning objectives. 

Additional guidelines
  1. Avoid postings that are limited to 'I agree' or 'great idea', etc. If you agree (or disagree) with a posting then say why you agree by supporting your statement with concepts from the readings or by bringing in a related example or experience. 
  2. Address the questions as much as possible (don't let the discussion stray). 
  3. Try to use quotes from the articles that support your postings. Include page numbers when you do that. o Build on others’ responses to create threads. 
  4. Bring in related prior knowledge (work experience, prior coursework, readings, etc.)
  5. Use proper etiquette (proper language, typing, etc.). 

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 [regularly participates; 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; 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; all required postings; most at the last minute without allowing for response time]; Critical Thinking [generally competent; information is thin and commonplace].

<70 = F—Timeliness [rarely participates; some, or all required postings missing]; Critical Thinking [rudimentary and superficial; no analysis or insight is displayed].

Quizzes (10% of Final Grade calculation)

Quizzes will be multiple choice and will be evaluated with full credit or no credit depending on selection of the correct answer. No partial credit will be awarded.

Assignments (15% of Final Grade Calculation)

Assignments will include a mix of qualitative assignments (e.g. written literature reviews, model summaries), and quantitative problem sets. Each problem should include assumptions, computations, and the final answers should be boxed. All assignments are due according to the dates in the Calendar.

Grading Policy

Student assignments are due according to the dates in the Calendar and Assignments items in the corresponding modules. The instructors 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. 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.

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.
