Fig. 5. Seeing down to the workspace
The team got points when its participants followed the given instructions, but if they did
not, their punctuation was decremented. Other way to measure the group effectiveness was
by comparing the number of movements required to get each piece of furniture where it
was last placed, against the number of movements the team actually made; the more
effective use of movements is then represented by a 0 difference. The game table was not
taken into account for this effectiveness score because a group could not get to that point. In
Table 5, the first and second rows show the score given for correctly following instructions
as “Instructions Score”, and the effectiveness in moving furniture as “Movements score”.
The percentage of time each group spent in each session stage is also presented in Table 5,
the row that follows the stage is the discussion time the group spent in that specific stage,
and the final row presents the total percentage of time they used for discussion periods.
Regarding a collaborative intelligent tutor, a clear opportunity to intervene is the fourth
team presented in Table 5. This team started almost immediately -after 2 seconds, with the
implementation and then they had very short discussion periods; through the data, it seems
that they worked almost in silence. In the audio tape at some point they commented “-
remember that we are not supposed to talk” with apparently no reason and they worked to
the end of the task in silence. However, they faked talking, that is, they pressed the talking-
turn key probably to bring the others attention.
