Finally, the applied numerical methods are easier to handle for newcomers, leaving the more complex methods like differential equations, Fourier transformations etc. Increase and sustain motivation for learning For an increasing majority of students the computer is accepted as a normal instrument to work with. It is accepted in a rather positive manner when compared to other media and this motivation does not seem to fade out with time. Computer simulations make use of this positive bias and can thus offer more interesting and fruitful opportunities for learning and training than traditional means and media. If simulations are not just used for a rather specialised purpose but offer a broader range of possible interactions through more complex user interfaces, the learners are in risc to be overwhelmed and to loose orientation.
Guidance is needed to avoid experience of failure and loss of motivation.
The use of complex simulations is definitely reduced, if no method for a flexible integration of guidance and exploratory actions is offered.
