Methods of Evaluation of Competencies:

Evaluation of student mastery of course competencies will be accomplished using the following methods:

The Astronomy course grade will be based on a minimum of 650 points.
Graded work for the course will include 4 tests, quizzes, written
assignments, and a cumulative final exam.

Grade Work                       Percentage of Course Grade
4 Tests                               40 - 60%
Chatroom/Discussion Participation      5 - 15%
Quizzes, Paper(s) and/or Project(s)    5 - 15%
Final Exam                            15 - 25%   
  Total                                 100% 

Caveats:

1. Students will need basic word processing and Internet searching skills for the completion of some papers, exercises and projects.
