With respect to the test, we have implemented an agent whose task is one of validating that
the answers are correct. Here, the learner answers the test offline (anytime or anywhere) and
then he chooses the upload option. The answers are sent to the portal through a file (text
message) so that they are evaluated by our agent. The result of the test evaluation is sent to
the apprentice through a text message. With respect to Chat, this it is available through the
interactive portal only. With this characteristic we provide the learner with a mobile tool
that offers bigger educational opportunities. In [5] the authors describe five properties of
handheld computers that produce unique educational affordances:
1. Portability - can take the computer to different sites and move around within a location
2. Social Interactivity - can exchange data and collaborate with other people face to face
3. Context Sensitivity - can gather data unique to the current location, environment, and
time, including both real and simulated data
4. Connectivity - can connect handhelds to data collection devices, other handhelds, and
to a common network that creates a true shared environment
5. Individuality - can provide unique scaffolding that is customized to the individual’s
path of investigation.
