Overview
- Influence: Interleaved practice
- Domain: Student Learning Strategies
- Sub-Domain: Learning strategies
- Potential to Accelerate Student Achievement: Potential to accelerate
- Influence Definition: Interleaving involves implementing a schedule of practice that mixes different kinds of problems, or a schedule of study that mixes different kinds of material, within a single study session. It can also involve mixing, or interleaving, multiple subjects of topics, as opposed to blocked practice, which typically involves studying one topic very thoroughly before moving to another topic

Confidence
The Confidence is the average of these four measures, each divided into five approximately equal groups and assigned a value from 1 to 5 based on the following criteria:
-
Number of Meta-analyses
- 1 = 1
- 2 = 2–3
- 3 = 4–6
- 4 = 7–9
- 5 = 10+
-
Number of Studies
- 1 = 1–10
- 2 = 11–50
- 3 = 51–200
- 4 = 201–400
- 5 = 400+
-
Number of Students
- 1 = 1–2,500
- 2 = 2,501–10,000
- 3 = 10,000–20,000
- 4 = 20,000–100,000
- 5 = 100,001+
-
Number of Effects
- 1 = 1–100
- 2 = 101–300
- 3 = 301–600
- 4 = 601–1,200
- 5 = 1,200+
