Review or Make-up


 

Most classes will consist of an introduction by the professor, followed by informal, interactive powerpoint presentations on the assigned papers, led by a student.

 

EVALUATION

 

Undergraduate student evaluation:

10% for participation in the class discussion about the selected articles.

30% for formal seminar presentations topical to the lecture at two different times.

10% for essay proposal with annotated bibliography, due six weeks before last class

50% for final essay, due April 4. 1% will be deducted for each day late.

Students will be responsible for giving an oral presentation on a topical article pertinent to the lecture of the day. They will do this twice so that they will have the opporunity to learn from their first presentation. The essay will be 3000-4000 words (not including references). It will describe a real-life situation (like catching a baseball, for example) in scientific terms, incorporating something from each lecture section. The purpose of this essay is not only to test the students knowledge, but more importantly to help them synthesize and apply this knowledge to real-world situations in a useful and memorable way. Undergraduates will be required to cite 15 papers and these may be review articles and/or papers covered in class. They will need to be able to coherently demonstrate that they understood the main concepts and where they apply. Undergraduates will receive formal feedback about their essay proposal.

 

 

Graduate Student evaluation:

10% for participation in the class discussion about the selected articles.

30% for formal seminar presentations topical to the lecture at two different times.

60% for final essay, due April 4. 1% will be deducted for each day late.

In the final essay (5000-6000 words), graduate students will be required to properly cite at least 30 journal articles. At least 20 of these must be original research papers (not reviews), including at least 10 papers that were not covered in the class. Graduate students will be required to show a greater depth of original synthesis and application of the concepts to a real life situation. Graduate students will require approval of their essay topic, but will not have to submit a formal proposal.
