GoalPost: LEGO programming exercise support

In an introduction to C programming exercise, it is important for students to promote their interest and motivation. Robot contest and group collaboration is one of the styles for the purpose. We propose a game programming exercise using a simple robot kit LEGO Mindstorms. We introduce an exercise model and develop support environment GoalPost. The system has some tools along the exercise process. The aim of our research is to improve applicative ability and challenging activity of students with group communication in programming exercise.
