How to solve a computational problem?
This educational video shows from top shot perspective the fictitious “brainiac” Tom when he solves a difficult colouring problem. You can observe the sketches he makes on his sketch-pad as well as his chains of thought, because Tom works in a thinking-aloud setting, i.e. he speaks out everything that he is thinking about when solving the problem. You can experience first-hand, how Tom first analyses the problem and then uses the key insights he gained to productively work on the problem until he reaches the final solution. The viewer, however, will not be left alone. At particular points the video will be interrupted with animated picture sequences in order to explain Tom's previous problem solving activities in more detail. Weak problem solvers can thereby deepen their knowledge about computational problem solving methods gained in lessons and lectures. They witness the usage of those methods by a strong problem solver virtually live.
The video has been derived from a study with weak and strong problem solvers who tried to solve the colouring problem in a thinking-aloud setting. The very efficient approaches of the over-achievers have been didactically reprocessed and reassembled to an exemplary computational problem solving process, which has a relation to real-life. At the beginning a picture story tells the scientific background of the video. Computer science students in the first semester who saw the video for evaluation highly appreciated the concept. Tenor: “entertaining and informative at the same time”.
