When I taught and from what I have seen in classrooms writing generally begins either with something read, a brainstorming session, a writing prompt, or a quick reflection on a personal experience. It could be a letter, a poem, a persuasive essay, a summary, or an opinion to name a few. It usually starts 3-4 days before the final product is expected and you work diligently through the process getting some feedback and edits before submitting the final product. All in all 3-4 days is the average time.
What if writing (at least the longer pieces) started weeks or even a month before the eventual expected date of being finished.
So let me take a standard:
Write informative/explanatory texts to examine a topic and convey ideas and information clearly.
This is an overall standard, not meant to be all inclusive, but will use this to explain my idea.
In the mean time ask others, for 5 - 10 minutes, to go in and respond either with questions or compare/contrast to a similar topic or ideas that they could explain. Then have the original author, having been given a few days, think about the concept and get feedback from peers. Have them rewrite or add to their original writing. Do this 4-5 times before you give them the assignment
This written assessment I see as coming in the form of something they read, let's say "how gemologists determine the value of a diamond?" Maybe not the most interesting topic, but the assignment for the class is to write an informative/explanatory text to examine a topic and convey ideas and information clearly.
Make sure they:
