Writing Pathways has some gems in it, including how to use writing checklists while avoiding the "checklist mentality." Lucy Calkins suggests placing student skills on a learning progression and then showing students the next steps to help them move up the ladder. I liked that the checklists, rubrics, and learning progressions were all included. I also appreciated the benchmark pieces that can help to show kids in conferences what is looks like to move up the ladder.
I have a few red flags about the sheer amount assessments suggested in this book. The amount of time that students will spend taking the assessments and the amount of time I would need to spend grading and analyzing the assessments is a bit overwhelming.
