SUMMARY:

This exploratory and ongoing research aims to analyze interactive processes of prospective teachers in an online and collaborative context. Triangle similarity tasks were planned and implemented in the virtual and synchronous environment VMTcG. The data (graphs, tables, textual transcripts, constructions on screens) of the research were generated in the environment itself and served as a basis for the re-elaboration of tasks, as well as for the analysis of interaction and aspects of mediation in the learning of (future) teachers . From the pilot implementation, the tasks were reformulated, proposed environment and target audience. The second implementation allowed the (re)design of the tasks in relation to the proposed type of task, of a closed nature for a more open scope. We observe that this change of perspective can help the teacher in the development of online tasks with different goals, from construction to theory and vice versa. At the end, we analyzed the first task proposed from the discursive point of view to verify the interrelationship of spaces and the continuity of the participants' interaction in the VMTcG environment. We also identified the different uses of the drag feature and the indications of these uses for the cognitive process of (future) teachers. Among them, we highlight the wandering drag and guided drag, which worked as an empirical-perceptive control in the exploration of properties and relationships of the figures built in GeoGebra.
