Collaborative classroom research among a group of elementary and middle school teachers provides insight into the effective use of the Three Level Guide. Building lessons around content area materials, teachers employed the Three Level Guide regularly, coming together to share successes and frustrations and to offer suggestions. Their reflective analyses of the use of the Three Level Guide offer insight into its impact on teacher effectiveness as well as its impact on students' academic achievement, critical thinking ability, and academic esteem.
