Fig. 3.
The learner's workspace with some feedback examples
fields which are not filled or not necessary for the task. The learner starts to
represent the information on the “Lagekarte” which are contained in the “4-
fach Vordruck”. For this, he only has to place the needed symbol with drag and
drop from the symbol box to the places on the map, which are described in the
message. The flooded area can be marked with the drawing toll. If the student
made some mistakes in this point, he get provided some feedback depending on
the chosen symbol, the number of attempts, the location on the map, and the
relative position to other symbols. Finally the goal of the learner is to solve the
problem correctly. This can be done by trial and error or conscientious. When
this is achieved, he gets a feedback and it will be saved automatically and marked
as resolved, then sent back to the teacher. So, if it is desired it can provide a
overview over the solution method of the learner.
4 Technical Requirements
The sample scenario presented in the previous section consists of the 3 most
important elements for the work of S2: “4-fach Vordruck”, “Lagekarte”, and
tactical symbols. In this section these are described in detail. It is divided in
an explanation of the presented possibilities and the required data collection
