These learning materials, developed in the SOLE Project (Leonardo
da Vinci Programme), are organised in lessons/information and activities.
They can be used in different contexts and with different learning
methodologies:
supported self-learning,
virtual class,
collaborative learning.
Being the lessons/information
self-consistent they can be used also in a self-learning mode.
The activities, on the contrary, require a tutor or a teacher
that, on the basis of the answers sent, interact either with individual
trainee or with the whole class. The activities performed by the trainees
are sent to a data base that can be enquired both by the teacher/tutor
or by any learner. In order to identify her/his own learners'
answers the tutor will provide the trainees with a code (individual
or group) that will have to be inserted in the provided field.
The Units are not to be
intended in a sequential order but for topic areas.
