The pedagogical approach embodied in these architectures is learning by doing , specifically, learning science via virtual experiments and via modelling.
Traditional media offer high authenticity but low interactivity.
Textbook illustrations and posters can provide thought-provoking pictures, tables, charts, and other depictions of complex information. Movies and video can provide gripping dynamical displays. But none of these media provide interaction. They cannot ask for more details about explanations that they don't understand. They cannot satisfy their curiosity about how efficiency varies with operating temperaturesby testing the engine over range of values.
