Interactive textbooks is an online learning platform designed to engage students. Each module is divided into three sections. The learn section introduces the theme with a short animated scenario. In the try section, students solve problems and complete exercises. With repetition, positive reinforcement and instant feedback, students master the material at their own pace. The play section is a mini-game with an adaptive feature so students can choose the level of difficulty. The try section is not only entertaining and fun; it shows students if they have mastered the material or if they need to try again until they do.
