Take a look at how Marzano’s Nine Instructional Strategies for Teaching and Learning and the elements and processes used when implementing the Strategic Instruction Model (SIM™) align.

The relationship between the High-Leverage Practices in Special Education (HLPs) and the elements and processes used when implementing the Strategic Instruction Model (SIM™) are remarkable.  Used in tandem they can empower all teachers with evidence-based instructional tools and interventions, which embed HLPs shown by research to improve achievement for students with disabilities.

According to John Hattie, practices with effect sizes of d>.40 have a greater than average influence on achievement. Take a look at the effect sizes of the compelling key features of the Strategic Instructional tools.
