My thoughts:
In an effort to integrate writing into our classrooms naturally and in a way that is easy to assess, could we:
- Ask students to pick one problem from every quiz/test and explain the process in words.
- As a review (or when a substitute is there), give them a random page number from their INB and ask them to summarize the concept/process in writing.
- Ask students to write a monthly reflection of something pertaining to class: a test, a quiz, a review game, an activity, a worksheet, seating arrangement, etc. This would also double as interesting feedback to the teacher.
- As an exit slip, write a summary of the lesson in text/slang or every day language and have them rewrite technically with correct vocabulary.
- On a test or quiz, give them a graph, diagram, chart, or table (pertaining to current classwork) and ask them to write everything they know about it, using as much vocab as possible.
- For those that use word walls, have them randomly pick two words and compare and contrast.
- Give a problem that is worked out incorrectly and have them to explain and correct the error in words only.
That's the best I can do in a way that feels natural to my teaching.
