Allow students to practice writing in chunks for a particular paper.
For example, begin with writing the introduction. Collect and make notations on it. Return to students so changes or corrections may be made.
Often students have “run away” papers. Holding them to one step at a time makes it much easier to redirect their writing should it be necessary.
Once you have approved the first step, move on to the next step by providing them with paragraph one page. Again collect and check.
If need be, students implement noted changes on another page.
Once the introduction and paragraph one are acceptable, students move forward with the next step, etc. This method allows those who understand to move ahead, while those needing to make necessary changes have a new page to write on. Students can then see their growth from page to page or paragraph by paragraph.
