Teacher-learner interaction quantifies scaffolding behaviour in imitation learning

Area of Science:

• Cognitive Science
• Educational Psychology
• Human-Computer Interaction

Background:

• Teachers often assume they adapt instruction to student learning progress.
• Empirical evidence for this adaptive teaching behavior, particularly during imitation learning, is limited.
• Understanding the dynamics of teacher-learner interaction is crucial for effective pedagogy.

Purpose of the Study:

• To investigate the interactive behavioral coordination between teachers and learners during imitation learning.
• To determine if behavioral data can support the belief that teachers account for learner progress.
• To identify bidirectional information exchange and shared knowledge during the teaching-learning process.

Main Methods:

• Analyzed manual movements of teachers and learners during a puzzle-solving imitation task.
• Utilized a bivariate autoregressive model to quantify causality and noise covariance.
• Calculated information transfer and shared information to assess interaction dynamics.

Main Results:

• Information transfer from teacher to learner (lateral motion) reflected imitation of spatial information.
• Information transfer from learner to teacher (vertical motion) indicated teacher monitoring of learner progress.
• Shared information in lateral motion increased with learning, signifying knowledge transfer.

Conclusions:

• Teachers actively and contingently scaffold imitation learning, demonstrating an intention to promote learning.
• Behavioral data provides a signature of adaptive teaching, supporting teachers' awareness of learner progress.
• Findings enhance our understanding of the fundamental nature of teaching and interactive learning.
