Graphical programming: a vehicle for teaching computer problem solving

Translating from a problem description given in a natural language to a solution expressed in a programming language requires many complex steps. Though many of these steps can be done mentally for simple problems, the process itself is important when dealing with complicated software. Expressing the process demonstrates not only the complexity of solving a particular problem but also the inherent difficulties in forcing beginners to jump from a problem description to a solution. Our experiences show that using LabVIEW and Alice as graphical foundations, with several carefully designed examples, may help students more quickly learn the process involved in computer-based problem solving than they would with traditional techniques.
