Seeing through the virtual reality: the effects of learning environment and task difficulty on difficulty perception,...

Area of Science:

• Educational Technology
• Cognitive Science
• Human-Computer Interaction

Background:

• Virtual Reality (VR) offers immersive learning, contrasting with traditional multimedia videos.
• Research on VR vs. video learning outcomes, especially knowledge transfer and mental models, is inconsistent.
• Task difficulty may mediate learning environment effects on cognitive processes.

Purpose of the Study:

• To investigate the interaction between learning environment (VR vs. multimedia video) and task difficulty (high vs. low).
• To examine effects on learners' difficulty perceptions, knowledge transfer, mental models, and retention.
• To provide empirical evidence for adaptive instructional design in different learning environments.

Main Methods:

• A 2x2 between-subject factorial design with 92 college students.
• Learning environments: Virtual Reality (VR) and multimedia video.
• Task difficulty levels: High and low, assessed using a dual-task paradigm.

Main Results:

• VR environments led to higher perceived task difficulty for challenging tasks.
• VR learning significantly enhanced knowledge transfer and mental model construction, especially for high-difficulty tasks.
• Multimedia video learning was superior for knowledge retention and mental model development in low-difficulty tasks.

Conclusions:

• The effectiveness of VR and multimedia video depends on task difficulty and learning goals (transfer vs. retention).
• Adaptive instructional design strategies are crucial for optimizing learning outcomes in diverse cognitive demands.
• Findings inform the design of both immersive and traditional educational media.
