| Abstract | dc.description.abstract | Concept mapping is a technique that allows for the
strengthening of the learning process, based on graphic representations
of the learner’s mental schemes. However, due to its graphic
nature, it cannot be utilized by learners with visual disabilities. In
response to this limitation we implemented a study that involves
the design of AudiodMC, an audio-based, virtual environment for
concept mapping designed for use by blind users and aimed at virtual
training and rehabilitation. We analyzed the stages involved
in the design of AudiodMC from a user-centered design perspective,
considering user involvement and usability testing. These include
an observation stage to learn how blind learners construct
conceptual maps using concrete materials, a design stage to design
of a software tool that aids blind users in creating concept
maps, and a cognitive evaluation stage using AudiodMC. We also
present the results of a study implemented in order to determine
the impact of the use of this software on the development of essential
skills for concept mapping (association, classification, categorization,
sorting and summarizing). The results point to a high
level of user acceptance, having identified key sound characteristics
that help blind learners to learn concept codification and selection
skills. The use of AudiodMC also allowed for the effective development
of the skills under review in our research, thus facilitating
meaningful learning. | en_US |
