screen magnificients could interpret the elements in
a good way. F2) The information must be shown in
small groups. For example, if a list is shown, it
should be divided into small groups of five or ten
elements.
F3) The system has to inform the user about all
completed tasks or the status of some tasks with an
alert. These alerts should be shown by the system in
a visual, audio, voice and vibration way to be
realized by the user.
F4) The message could be a text message and/or
an email. If an email is sent then it should contain
text, well-formed links and images with alternative-
text only.
Table 1 shows the different tasks and steps that
users should perform when they want to complete a
task. The first column shows the name of the task,
the second column shows the steps to perform in
each task and the third column explains how to make
each step accessible for everybody. This explanation
takes into account the features described in section
3.3 classified as F1, F2, F3 y F4.
4 CONCLUSIONS AND FURTHER
RESEARCH
This paper presents a theoretical approach for
creating to create accessible collaborative learning
modules for mobile devices. This approach has as a
starting point some previous studies of m-learning,
accessibility in mobile devices and collaborative
learning for personal computers.
This research is centered in the collaborative
module which would allow teachers and students to
collaborate in the learning process through mobile
phones. Our study provides the architecture of a
mobile LMS which includes a collaborative module.
It specifies the main features that a collaborative
learning module should have to be accessible in
mobile devices. Finally, this approach specifies the
different features that a mobile device should have
to be accessible for everybody.
Currently, we are working on implementing and
evaluating the theoretical approach.
