In the reflection version the players receive reflection prompts that aim to trigger self explanations (specific declarative knowledge on proportional reasoning as well as procedural information). The reflection prompts are menu-based and structured which means that players can select their answer from a list of options, and the options are matched to the prompt. In this way cognitive demands are lowered which may support below-average players. The assumption is that the reflection prompts will affect learning, and that the procedural information can help the players to structure and represent their explanations.
