ICT are transforming Cuban higher education towards the adoption of blended-learning and distance learning. This dissertation focuses on investigating the effectiveness of using social software to support collaborative learning in a Cuban university. Five studies were conducted within three phases that included diagnostic, integration and validation of the social software that was used to support collaborative learning. A didactic model was created to integrate social software within Cuban teaching and learning in higher education. Social Network Analysis and content analysis were used to evaluate the effectiveness of social software to support students' learning through their collaborative learning relationships and through their posts in wiki pages and online discussions. Statistical analysis was used to evaluate students' self-efficacy as a measure of their achievements in social software-supported collaborative learning. The findings confirmed social software’s suitability to support collaborative learning, as it increased collaborative learning's effectiveness, compared to face-to-face collaborative learning. Specific findings were revealed for the use of wikis and online discussions within teaching and learning, which are extendable to other social software tools. A didactic model to integrate social software in Cuban teaching and learning, as well as a framework to analyse students' interactions, were used for first time and validated to extend its use among Cuban university stakeholders.

Problem statement
6. Benefits of collaborative learning
• Both facilitators and learners become active
participants in the educational process (Brookfield,
1986).
• The hierarchy between facilitators and learners is
eliminated (Bruffle, 1999).
• A sense of community is created (Kaplan, 2002).
• Knowledge is created, not transferred (Sheridan,
1989).
• Knowledge is considered to be located in the
community rather than in the individual (Whipple,
1987).

8. Benefits of social software use in
education
• can be individualized in design and use
• can represent problems more realistically
• can display each step of a difficult problem
solving task
• can afford group discussion and
collaboration across distances
• can provide immediate feedback for
monitoring and evaluating student
progress
