Considerations

The students always have to know where they are, from where to where they have come in the material and where they can navigate.
The titles should be short, clear and exact.
The activities should be alternate within a unit so as to keep up dynamism.
We can’t give any kind of information without purpose. Provide the necessary texts and descriptions when they are needed for problem solving.
Accordingly we have to break the texts into small units.
By designing individual learning paths we can differentiate the students.
Keep the units in small size. They are easier to desing and easier to overview and use.
The review in the induction part helps to orientate and navigate in the material. Accordingly we should refer to the place of the unit in the whole material. We can give some advice, too, to use the unit.
