Size and Saliency in Instructional Hierarchy
The instructional hierarchy diagram incorporates size and saliency elements where set size determines the amount of teaching, with low sets for accuracy building and large sets for generalization and adaptation. Saliency or explicit instruction is high at the hierarchy's bottom and decreases as you progress. Small sets involve highly explicit instructions, repeated practice, and detailed feedback, which are gradually faded during the adaptation phase. It is crucial to rely on scientific evidence to determine set size and repetitions, such as aiming for declarative skills of 40 digits per minute before moving to the next skill. This hierarchical approach helps organize research findings and offers practical guidance to educators. For instance, if a student is accurate but slow, below a certain cutoff, explicit timing should be avoided based on research findings. The instructional hierarchy acts as a framework to tailor interventions based on a student's performance level, incorporating insights from various studies and ongoing research efforts.
