Abstract

TREVISAN, André Luis; FONSECA, Maycon Odailson dos Santos da  and  PALHA, Sonia Abrantes Garcez. Proposition of tasks with DCIT in Calculus classes. Rev. Diálogo Educ. [online]. 2018, vol.18, n.58, pp.713-738.  Epub Feb 06, 2020. ISSN 1981-416X.  https://doi.org/10.7213/1981-416x.18.058.ds06.

Considering that the process of elaboration, application and refinement of tasks that make use of DCIT is an important activity in the scope of teaching, the objective of this text is to present a reflection about the results of a teaching experience in which it was proposed a task with the use of Geogebra in the discipline of Differential and Integral Calculus. To do so, it adopts design-based research assumptions and presents a retrospective analysis of data from the work with a task to explore the ideas necessary to understand the concept of derivatives. As a result of this reflection, an alleged “failure” in the interaction between the students and the application, related to aspects of the learning environment, in turn interrelated to each other, is recorded: the task statement; the DCIT; the interpretation of the actions, explanations and interaction of the students; the interaction between teacher and students in the process of formalization. This result confirms the importance of an integrated analysis of teaching experiences and allows us to point out specific suggestions for improving the interaction between students and the application in terms of task development and the teaching and learning environment.

Keywords : Teaching and learning of Differential and Integral Calculus; Mathematics tasks; DTIC; Teaching and Learning Environment.
