Course Requirements

Attendance at all class sessions is expected.   One point each week will be awarded for attendance and participation in class exercises.  These may include lecture, quizzes, lab, group work, computer explorations or other activities.

Course Materials:  Please bring the following to every class:
    § Your textbook and notebook.
    § Scientific calculator with logarithms, exponents, scientific notation, and a memory.
    § Pencil, eraser, 6" ruler, and a colored pencil (any color).

E-Mail: Students must maintain a valid e-mail account (either through NEIU or an e-mail service) and must pick up messages at least every 2-3 days.
 
Homework:  Homework will be assigned frequently and regularly.  Assignments and due dates will be posted on the homework web page.  Many assignments will require that you prepare materials to present in class.  For example, you may be asked to find a journal article related to a particular topic and teach your colleagues about it in class.   If you are not prepared on the due date, these assignments cannot be made up.  Grades for this type of assignment will be based partly on evaluation by the instructor and partly on evaluation by your peers.

Some homework assignments will be completed and handed in by individuals, and some will be handed in by teams.  Each paper handed in should list only the names of the students who participated in producing the final product.  Team members should first outline the solutions to problems on their own, and then should work together to complete the solutions.  Only one grade will be assigned per team.  When solving quantitative problems, be sure to use the hints linked to this syllabus.
  If your homework is not ready on the due date, this must be discussed with me on or before that date.  No homework will be accepted more than one week late.

Quizzes:   Quizzes will be announced in advance and factored into the grade as homework assignments.

Expert Witness Report:  A few weeks into the semester, you will be provided with geologic and analytical data on a “real-world” field site with contaminated ground water.  More data will be provided throughout the semester, and homework assignments will be based on the data.  You will work with the data to practice various methods learned during the class.  Several homework assignments will involve this site.  Near the end of the semester, you will be asked to examine all the data and render a decision identifying the source of contamination.  You will construct an expert opinion report explaining and supporting your conclusions.  More information on the format and content of the assignments and final report will be presented as the semester proceeds.
 
The expert witness report will be evaluated on the basis of the following considerations:
  * Content  (Is the hydrogeologic analysis logical, consistent, well-reasoned, and complete?  Are arguments and conclusions well-supported?  Is the degree of uncertainty in the analyses quantified and evaluated reasonably?)
  * Organization  (Are all the required sections present?  Is information presented in a logical order, with appropriate headings and subheadings?)
  * Format and presentation  (grammar, composition, typing, clarity and completeness of figures/tables/graphs).  More information on format will be given later in the semester.
 
Assessments: Students must participate in all assessment activities ("green sheets").  I want to learn how well certain concepts are getting across and how the class is feeling about the material and the course as we go along.  At the end of each class period, you will anonymously assess this.  On each green sheet, assessment questions will help me find out how well the day’s outcomes were achieved.  This may be done in the form of an ungraded quiz-type question, a “muddiest point” question, or survey-type questions.  This information will help me to determine the extent to which the course is meeting its goals.  To provide me with the most information so that I can make the course better, I ask that you give me your most thoughtful, honest feedback-- the more, the better.  A list of course outcomes is linked to the web version of this syllabus.  In addition to these outcomes, each class day you will receive a list of expected daily outcomes.  You also can find these daily outcomes from the outline of topics on the web version of this syllabus; just click on each date.

Academic integrity:  The NEIU policy on academic integrity will be strictly enforced.  A site from the University of Indiana explains and gives examples of plagiarism and provides helpful tips on how to avoid it.

Flexibility: This outline will change as the semester evolves.  Please allow for flexibility in topics and assignments.  Check this page frequently for updates!
