Abstract
We are interested in whether inducing homework plans can increase homework performance and learning. We are also interested in whether we can improve student meta-cognition.

Experimental Design
Experimental Design
There are three conditions: Control, plan, review then plan.
Experimental Design Details
All students at this middle school were randomly assigned to one of three conditions. Control: At the end of math class whenever there was homework over a 5 week period these students completed a workbook with math problems. Plan: At the end of math class whenever there was homework over a 5 week period these students completed a workbook with math problems + a plan for the implementation details for when and how they’d get their homework completed that night. Review + Plan: At the end of math class whenever there was homework over a 5 week period these students completed a workbook in which they reviewed and reflected on their previous homework plan and then made a plan for the implementation details for when and how they’d get their homework completed that night. All students were asked to make a plan to mail a form to the researchers on a specific date during the winter holiday. We recorded whether they succeeded in mailing it to us.
