Elaborative interrogation

Overview

  • Influence: Elaborative interrogation
  • Domain: Student Learning Strategies
  • Sub-Domain: Meta-cognitive/self-regulated learning
  • Potential to Accelerate Student Achievement: Potential to considerably accelerate
  • Influence Definition: These strategies enable learners to commit information and skills to memory. In combination, practices of elaboration (such as note-taking or forming questions about course material) are often combined with practices of organization (such as outlining or information mapping).

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+
