Adaptive training instructional interventions: A meta-analysis.

Area of Science:

• Educational Technology
• Military Science
• Human Factors Engineering

Background:

• Military training modernization emphasizes technology integration for enhanced engagement and future readiness.
• Adaptive training (AT), personalizing instruction to individual strengths and weaknesses, is a key strategy for modernization.
• Existing research on AT best practices is fragmented, necessitating a comprehensive review.

Purpose of the Study:

• To conduct a meta-analysis evaluating the effectiveness of various adaptive training instructional interventions on learning outcomes.
• To identify which specific AT techniques yield the greatest improvements in trainee learning.
• To provide evidence-based design recommendations for future AT systems.

Main Methods:

• A meta-analysis was performed on 30 peer-reviewed publications examining adaptive training interventions.
• Studies were categorized based on the specific adaptive intervention employed (e.g., difficulty, feedback, scaffolding).
• The impact of each intervention type on learning outcomes was quantitatively assessed.

Main Results:

• The effectiveness of adaptive training varied significantly across different instructional interventions.
• Adaptive difficulty techniques demonstrated the highest positive impact on learning outcomes.
• Adaptive scaffolding and remediation/test-out techniques also showed significant effectiveness.

Conclusions:

• Adaptive training is a valuable approach for military education, but its effectiveness is intervention-dependent.
• Adaptive difficulty, scaffolding, and remediation are recommended AT strategies for maximizing learning.
• Findings inform the design of more effective and responsive future adaptive training systems.
