labyrinths are wonderful little puzzles that can be used to show what algorithms are, how they work, and what that different algorithms have different strenghts and weaknesses. in a current research and design project, we are creating MOOC units for parts of the »ways of thinking in informatics course«. for computational thinking, this bachelorproject for two persons or masterproject for one person should design and implement a »labyrinth lab«, where students can experiment with algorithms in labyrinths. eg. it should be possible to see how different algorithms solve different labyrinths, follow the execution of the algorithm debugger-style through the labyrinth, and maybe even construct individual labyrinths for the algorithms to solve.
