The document discusses using data from CAT4 (Cognitive Abilities Test) assessments to develop literacy and learning strategies tailored to students. It describes analyzing CAT4 data through MIDYIS graphs to understand students' strengths and weaknesses. Various teaching methods are suggested based on where students fall in the different quadrants of the MIDYIS graph. Effective strategies include using word walls, sequencing exercises, and concept mapping. The challenge of embedding many techniques into lessons is also discussed. The key takeaways are how to use CAT4 data to characterize a classroom and select appropriate teaching methods for students.
