Table 3. Percentage of Interactions per Communication Channel. Average % of interactions taking place over the different communication channels employed in our study. No significant differences were found between different groups of students. Moodle interaction count was increased only if the post received an answer. The collaborative workspace let us include interactions from blog posts, document shares, reminders or messages in the collaborative space. Each chat and classroom IRC session (sequence of messages exchanged without stopping for more than 3 min) counted as a single interaction.
