For learners with limited knowledge of content, it is often better to go with “lower fidelity” images (flat images as opposed to more realistic pictures) as this design approach has been proven to help learners focus on the essential information, minimize distractions, and speed up encoding.
We placed the learner in an institute full of locked rooms and clickable displays. The learner has to navigate through the institute the same way they are to navigate the book, unlocking rooms and earning game pieces as they answer challenges using their actual book along the way.
In the end they are awarded a trophy for having solved the challenges which increased in difficulty as they progressed through the course.
