I Built a Classroom Student Differentiation Machine - And It Works for Every Chapter!
You've just finished a unit assessment. Some kids aced it. Some missed a few objectives. Some missed a lot. Your district wants differentiation — meaning every student should be working on their specific gaps, at their reading level. In the past, that meant hours of sorting data and writing activities. Realistically? It meant one worksheet for everyone. Not anymore. I built an automated pipeline using Claude Cowork that turns my Google Forms results into a fully individualized, scaffolded review activity for every single student — formatted, named, and ready to print. Here's how it works. -- The Pipeline, Start to Finish I set up a custom skill in Claude Cowork — a saved set of instructions that knows my students, my curriculum objectives, and exactly how the output should look. I built it once. Now I just upload a CSV and say "run the gap analysis." Claude scores every student's assessment (MC automatically, free response on a 0/1/2 rubric), maps every wrong answer to a curriculum objective, and produces a color-coded Excel gap analysis with per-student scores, question breakdowns, and tier gap profiles. Then it generates one personalized .docx activity per student, targeted to that specific student's missed objectives. That's the part that still blows my mind. -- The Differentiation Is Real Every activity is built around what that student missed — not the class average, not a group. But here's what makes it truly scaffolded: the format is differentiated by NWEA reading tier. - Tier 1 gets matching tables, fill-in-the-blank, and word banks — concrete formats that reduce reading load — plus stretch questions pushing toward summarization - Tier 2 gets a matching warm-up, then short-answer with evidence prompts - Tier 3 gets analysis and comparison paragraph tasks - Tier 4 gets evaluation and synthesis essays Students who scored perfectly still get a robust activity — a 10-item matching section plus enrichment questions at their tier's depth. No one gets a pass, no one gets busywork.
