Each summary should provide (1) complete citation information about the paper (with the same requirements as in the daily readings summaries), (2) a summary of the key points and take-home lessons provided by the chosen paper, (3) an analysis of the paper's strong and weak points, and (4) discussion of related or subsequent work that the paper suggests (i.e., on this last point, another way of putting this is what could a researcher do next given these results). Do not simply echo the paper but instead provide a synthesis of the ideas and results found in it.
In preparing the summary, you probably will want to read other papers by the same group and related work. Include references/citations to those other papers.
The appropriate length for a summary is at least two single spaced pages.
Include a copy of the paper. Turn in a printed copy of your summaries and don't forget to put a copy on your Web page. Place your email address on all assignments.
