Published articles are accessible through E-journals link on the GMU Library webpage unless noted. If you encounter any problems, contact the instructor.

 

Attendance: All students are expected to attend all sessions during the semester. One absence only will be permitted without penalty. Any additional absences will result in lost credit for that week.

 

Honor Code: Preparation for each weekly session can be done in groups, but weekly graded materials (summaries, quizzes) must be produced by students individually. If published material is used in a summary, references must be given. Group presentations are collaborative and group members will be graded as a group.

 

Grading: Student grades will be based on weekly news summaries, quizzes, presentations and participation in class discussions. There are 13 graded sessions, 12 of which will determine the final grade. If a student attends all sessions, the lowest grade will be dropped.

 

Weekly newspaper-worthy summaries: Each student is expected to bring to each class session a one-page or less newspaper-worthy summary of the topic being discussed that week. This is usually based on the assigned reading, but can also include other materials obtained by the student. It must be suitable for the nonscientific public, exciting, timely, lively and publishable.

Weekly quizzes: At the end of each class discussion students will take a short quiz concerning the topic assigned for that week.

Presentation: Group presentations will be graded by the class members and the instructor.

Participation: All class members are expected to attend each class session and participate in all discussions. No missed work can be made up or turned in late.

 

Prize Paper Assignment: Each student must propose a paper for discussion by the class. Search the recent literature for a paper you think will be interesting and worthy of discussion and write a one-page justification. The instructor will choose one of these for discussion during the semester; the sponsor will not be required to turn in a summary or take a quiz that week.

 

Group Presentations: Groups will be formed by the instructor by the third week of class and each group will choose a paper for class discussion. The paper must be approved by the instructor at least two weeks before presentation. The group members will be responsible for introducing the topic the week prior to the presentation, presenting the topic, leading the discussion, and giving the quiz. Presenters will be evaluated by the class and the instructor.
