ACTIVITIES REQUIRED OF STUDENTS

A. Attendance: Credit may not be awarded if the number of absences exceeds

the number of times that the class meets per week - namely 5 hours. Punctuality will be strictly enforced.

B. Tutorial/ Laboratory Sessions and Field Visits:

A number of tutorials (problem-solving) will be held, and each student must have his scientific calculator during all the classes. These sessions will provide ample opportunity to ask questions, to clear doubts, to improve problem-solving skills, and to understand practical applications. Computer usage will form part of these sessions.

A number of laboratory sessions will be held to provide introduction to water and wastewater analysis.

Field visits shall include visits to water and wastewater treatment plants.

C. Home assignments:

Use of library facilities and internet resources shall be incorporated. These should be submitted in time. Late submissions will not be accepted for evaluation

D. Course Folders:

All tutorial sheets (question papers and answer sheets), assignments, lab reports and test papers shall be placed in a Course Folder. The Course Folder must be submitted on specified dates (to be announced in the class).

D. Tests and Final Examination:

These should be taken on the dates and times which shall be announced at least one week in advance. No make-up tests will be given except under extremely special circumstances.

Tentative dates for Tests:

Test 1: Wednesday, September 10, 2008

Test 2: Monday, October 6, 2008

Test 3: Wednesday, November 12, 2008

EVALUATION PROCEDURE:

The final grade for indicating the quality of academic work represents the student’s successful performance in all the instructional areas of this Course.

The final evaluation shall be based on the following:

Home assignments, tutorials & labs: 30%

Tests: 30%

Final examination: 40%

GRADING SYSTEM: A Excellent 85 - 100

B Good 70 - 84

C Average 60 - 69

D Poor 50 - 59

F Failure < 50

DISABILITY ACCOMMODATIONS:

If a student has a documented and declared disability, reasonable accommodations will be provided if requested by the student according

to the recommendations of the office of Counseling and Disability Services (CDS) (912) 356-2285/(912) 303 1650/(912) 356-2202.
