Towards making block-based programming activities adaptive

Block-based environments are today commonly used for introductory programming activities like those that are part of the Hour of Code campaign, which reaches millions of students. These activities typically consist of a static series of problems. Our aim is to make this type of activities more efficient by incorporating adaptive behavior. In this work, we discuss steps towards this goal, specifically a proposal and implementation of a programming game that supports both elementary problems and interesting programming challenges and thus provides an environment for meaningful adaptation. We also discuss methods of adaptivity and the issue of evaluating student performance while solving a problem.
