He has conducted work in early reading instruction, writing instruction, and cognitive strategy instruction that leads to self-regulated learning. More recently, he has extended his work by seeking to understand how to create schools as learning organizations that create the capacity for continuous learning and improvement. Currently, he is conducting a study to explore how teachers can provide concurrent academic and social support for students with significant learning and behavioral difficulties.
