A randomized study analyzed 49 secondary pupils using an adaptive algebra system with or without motivational pedagogical agents. The agent condition showed descriptive gains, but its adjusted post-test advantage and error-rate difference were not significant. Interaction analyses highlighted different choices about optional learning activities and the importance of prior knowledge. The study illustrates why engagement paths deserve attention, while a small sample and 25-minute intervention cannot establish durable benefits from adding an agent.
