An appreciation for research design and data analysis may help the attacker. He or she will be required to listen well, think quickly, ferret out logical flaws and opinions that are disguised as facts, and question the empiricism of quoted materials. An attacker should be well prepared and have read the opposite side of the issue. Attacks should not be made on personal attributes of the participants but on the merits of the prepared presentations and the ideas put forth in the issues. A fielder will be responsible to answer any questions regarding the groups' s presentations.
Fielders are also responsible for any important material omitted by a group member.
Because fielders can be asked questions about other members presentations, it is a good idea to know what the other members are going to say. If the group consists of three members or fewer, the fielder position will be assumed as a secondary role for all. Grading Grades will be based upon the clarity of the arguments, both written and oral. Grasp of the issue and important related points. Proper use of supporting empirical evidence.
