Features of Direct Instruction: Interactive Lessons

Rolf et al. (2021) mapped the six moving parts inside every Direct Instruction lesson.

They did not run an experiment. They described how the parts fit together.

The paper is a blueprint, not a scoreboard.

The six parts are: clear formats, flexible grouping, active responding, responsive interaction, data decisions, and mastery checks.

When any part is missing, the lesson loses power.

All six must run at the same time for the best results.

Slocum et al. (2021) wrote the sister paper the same year. They looked at content analysis instead of lesson delivery. Together the two papers give you the full DI engine.

Ganz et al. (2009) went further and actually tested DI language lessons with three children with autism. They showed the six features work in real life, not just on paper.

Early et al. (2012) used interactive video to teach staff how to run lessons. Their focus was trainers, not students, but they still leaned on the same idea: keep the learner active and check each step.

Use the six-part checklist when you write or buy a lesson. If a script skips active responding or has no built-in mastery check, fix it or pick another. The paper gives you the specs to judge curriculum fast.
