Readers who are familiar with the one or the other sample case mentioned
above may admit that being able to challenge the target in the way described
can be seen as a clear indicator of mastery.
Challenging the target is just one of the many educational patterns supported
by means of direct execution. Figure 8 illustrates another example of changing
decision trees by hand which immediately return results of varying quality.
Fig. 8.
Challenging decision trees with regular patterns on a fixed set of input data
Webble technology-to be more precise: meme media technology, in general-
allows for many more sophisticated educational patterns. One of the key features
is that composite meme media objects may be decomposed in different ways.
For instance, users may peel just one object off a larger construct to replace
it by another one. Intermediately, the composite object is loosing its ability to
execute the function it has been built for. After plug in of another component,
the larger composite object becomes immediately operational, again.
This enables teachers to set up a large variety of playful exploratory settings.
Think of composite objects in which replacing one component by another does
drastically change the behavior ... or not. Replace, for instance, one correct
procedure for solving a certain sub-problem by another procedure implement-
ing some heuristics which in many cases returns them same result, but not
always. This calls for a competition in finding the simplest cases showing the
difference.
