13th International Congress on Mathematical Education Hamburg, 24-31 July 2016 1 - 4 COLABORATION IN TEACHER INITIAL TRAINNING: ANALYSIS OF CONSTRAINTS Roberto M. Araújo Filho, Verônica Gitirana, Celso Gonçalves LEMATEC-EDUMATEC-UFPE, Recife , Brazil; UNITRI, Uberlândia, Brazil. This paper discuss main constraints presented in a collaboration online environment for teacher training. The theoretical framework was based on Computer Supported Collaborative Learning. The method was a construction of an environment to promote collaboration with a script, in a proposed activity to for teacher initial training, when they had to build a class to teach function using Modellus, using the online environment. The data analyze shows that most f constraint comes from technic problems, evidencing the need for an online environment, which enable better communication among participants in a collaborative session. INTRODUCTION This paper presents a cut of a master essay that aimed to analyze math teachers´ collaboration in an online training. In the original research, it was analyzed teachers´ interactions and environment configurations, which was specially designed for the course. In this paper we drew a cut, undertaking an analyze of the meeting constraints, found out on diverse technic and technologic aspects, on script proposal and on participants identification in each session. Our theoretical framework is Compute Supported Collaborative Learning, investigated by some researchers from Education and Math Education, among them; we use Stahl et al (2006) e Dillenbourg (2002). COMPUTER-SUPPORTED COLLABORATIVE LEARNING The Computer Supported Collaborative Learning (CSCL) is a theory which draw attention to learning while people interacting on online collaboration environment. In doing so, CSCL draws attention to some elements, that according to the theory, comprises collaboration in a online environments, which are objects of CSCL investigations: environment structure and factors which determine collaboration. Stahl et al (2006) define CSCL as an online learning way that occurs within joint participation of all subjects involved in the process, considered as final product what is determined by the group to be. According to Stahl et al. (2006), CSCL cannot be considered when isolated ideas when joined make up a final product, but essentially as a mutual production within all participating. These researchers do not ignore individuality. It is from his/her individuality that a person construct his/her reasoning. What they mean is that CSCL does not concentrate on this particular thinking way. In order to structure a CSCL session it is necessary a previous planning. Dillenbourg (2002) calls this previous planning by script. According to him, Script is a guidelines that mediator – someone who organizes the session - prepares and communicates to subjects previously to the session. This script according to Dillenbourg (2002) must contain all information referring to session, from software programs to actions and roles played by the subjects.
