Points of View Reference Center essays were designed to present a balanced view of at least one aspect of a controversial issue as a springboard for further research, evaluation, formulation, and construction of one’s own argument or position on the issue. Each Overview provides basic facts, names, and figures on a topic. This provides students with a strong, yet neutral, starting point in their research. The Point and Counterpoint essays summarize viewpoints on the topic, using an objective perspective supported by sources. Each is an example of one viewpoint on a given issue meant to serve as a model for students in supporting an argument.
