setting
In a TV contest, a contestant chooses one of three doors; behind one of the doors there is a prize and behind the other two there is nothing. After the
competitor choose a door, the host opens one of the other and reveals that there is no prize. The host then asks the competitor's choice whether to keep or
want to switch. It is advantageous, in statistical terms, to switch or keep?
data
Two students (Raquel and Mariana)
Raquel from Business, Mariana from Education
Both correct answers
Two different kinds of answers
data

Raquel (Business student)
Raquel (Business student)
For her the problem is solved.
First outcome (decision tree) evaluated as possibly relational.
Second outcome (algorithm) evaluated as multi-structural.
Raquel (Business student)
Mariana (Education student)
=INT(RAND()*3)+1
On the two first cells, generates a random number from 1 to 3.Doors that the contestant could choose.
This empirical experiment allow her to simulate the outcome.
This outcome was evaluated as relational close related to
extended abstract.
Mariana (Education student)
Final remarks
Evidences of proceptual divide: Raquel clearly with a procedural thinking taking refuge on algorithms and Mariana proceptual thinking with some meaningful combinations of procepts.
The model of analysis used to characterize the outcomes appears to work in identifying the different outcomes.
