We have found that "mid-course corrections" are helpful for comp courses, so we recommend a short evaluation be given about the middle of the semester (shortly after the first portfolio is collected). These can help you adjust to your students' needs while there is still a significant amount of time left to implement new strategies, if necessary. The sample includes prompts teachers have found useful.
Having students complete group and self assessments after a collaborative project builds in accountability. We'd be happy to include additional prompts you've found useful.
Finally, although you'll give the composition final evaluation form, supplemental questions can also give you more specific feedback about COCC300.
