The Gradual Release of Responsibility Instructional Framework is widely accepted as a "best practice" in the world of education.
For teachers, the "I do" and "we do" steps of explicit and guided instruction are the highest leverage part of a class. This is the time when teachers introduce new concepts, skills, and/or content and model the thinking required for the upcoming learning activities for the class before guiding the students through whole-group or small-group practice.
The goal of these steps of the gradual release is to build connections between the students' prior knowledge and new concepts and content and help students develop a schema for the work they will be doing independently.
An approach to delivering instruction that allows for two minutes of quiet processing (thinking and writing) followed by two minutes of oral processing (partner talk) for every ten minutes of direct content delivery (lecture, group reading, demonstration, modeling)
Short term memory has limited capacity and direction. “Chunk and Chew” or 10 → 2 + 2 increases the retention of information and provides students an opportunity to process new learning. Embedding this principle into teaching creates frequent, informal opportunities to hold students accountable and check for understanding.
For every 10 minute “chunk” of input, students are provided with four minutes of structured processing time: two minutes to reflect, solve, or apply and two minutes to refine their thinking with a partner. Like all partner work, this works best when accompanied by clearly articulated expectations and established routines.
