This editable doc contains six on-line sources relating to the topic of the effects of zero tolerance policies on the attitudes, behaviors, and actions of young people. All sources are links to full-length articles and pdfs of research.
The format follows the AP Language template for the synthesis question. You could edit the sources down to just a few; you could divide the class into groups and have one group report out on the article / research, etc. You could also use this as a resource for students who are beginning to conduct research on the impact of zero tolerance policies on children and teens.
If you are working on PARCC preparation for the PBA and EOY essays, this resource will allow you to have several resources at your fingertips.
