Supporting Strategic Writers (SSW) is an instructional approach and curriculum for college developmental English and integrated reading and writing courses. SSW is based on strategy instruction integrated with practices common in college English. Students learn strategies for writing and critical reading of sources based on rhetorical analysis and genre. In addition, they learn metacognitive, self-regulation strategies such as goal setting, task management, progress monitoring, and reflection. Research over 10 years, funded by the US Department of Education, included 3 experimental studies that found large positive effects on quality of writing and motivation. The purpose of this cost analysis is to help college personnel, including both administrators and faculty, make decisions about whether to use the SSW curriculum in their developmental courses and to guide them in allocating sufficient resources for implementation.
