Task

Every trainer has some tools?Which tools have teachers?

Do they need tools?Teachers say: we have a lot to do , too much – and it is a difficult task, we have no time, for preparing any change

IdeaWe have again and again students who show their competence by

developing programs in some aspects of cultural techniques - reading, writing and arithmetic.: apps.tugraz.at

• We asked: Can we do more than deliver tasks and check right or wrong?

Tutorial Intelligence

One aspect of this problem ist to give every student the „right“ task.

We remember the problem of teachers – often with some more than 20 students in one class:

In domains with a dominance of drill & practice – for example the multiplication tables, they are physically too restricted for perceiving significant quantitative aspects of the performance of single students

and the whole class.

Giving the rigth task is just orientated to the „mean“We started to

Program / Checklist

• The system should estimate the competence grade of the learner

• The system should provide appropriate tasks or categories of tasks according to the competence grade of the learner.

• Nevertheless the tasks should tend to be challenging.

• The system should ensure that already well-done exercises are repeated and practiced. After succeeding a problem the probability for a repeated display decreases in two levels

(similar to a Leitner System )

Checklist cont.• In general the system should be motivating and show that

learning can be fun.

• The system should record and safe fine-grained data of all done exercises, test results and the current competence grade of the learner in order to prepare the next sessions in an adequate way.

• It should relieve the teacher from this unsolvable task as an information processing tool

• We planned an ubiquist system with interface for the conventional desktop browsers and also for Android and Apple mobile devices

• That was a first step towards Learning Analytics & Educational Data Mining

Big Data?Here you see the actual total statistics of our program to diagnose the

exact competence in computing the multiplication tables
