A Visual Interface for Concretizing Sorting Algorithms

Algorithm visualization is an efficient way to teach programming. Several different visualization techniques have been developed in the past decades. The Concretization Environment Framework, CEF, combines algorithm visualization with concrete objects (e.g. Lego Mindstorms robots). CELM, Concretization Environment for Lego Mindstorms is an application of this framework. By using the framework, the user can turn the mental model the user has into a concrete one. User feedback on the framework and its application has confirmed the functionality of the concept and the usefulness of the approach.
