A integração da Abordagem Documental do Didático e um processo de Design para o desenvolvimento de uma plataforma de suporte ao ensino a distância.

In this paper, we deal with the integration of the Theory of Documentational Approach to Didactics (DAD) with a design process, as a methodology for the construction of an artifact directed to teaching geometry online. The ADA provides theoretical support to guide the analysis of resource choices and production of teachers' documents and brings reflexive research as a methodological part to analyze the actions of the teacher in documentational genesis. Thus, following seven steps of a design process: define, research, ideate, prototype, select, implement, and learn, we relate design techniques to scientific research methods. Aiming to solve the difficulties of online teacher planning of geometry, we set up a methodological structure for the construction of a platform. The methodological structure was composed of the application of field research, problem mapping, question method, reflexive investigation, brainstorming and prototype. The methods were chosen according to the objectives of each of the seven stages of the design process. In a first analysis, it is possible to identify the potentialities of the integration of the ADA with design processes, to produce an artifact that assists teaching activities. [ABSTRACT FROM AUTHOR]
