Highlights：

• In-game real-time feedback produced significantly higher performance outcomes.

• Feedback delivered by pedagogical agents resulted in largest retention outcomes.

• Feedback delivered as audio alone produced negative gains in assessments outcomes.

• Agent interface modalities did not vary across performance and mental demand scores.

• Feedback delivered as audio alone resulted in significantly lower mental demand.
