摘要：The present work presents the pedagogical use of Network Educational Technologies (TER), more specifically video, as mediator of the teaching-learning of Agroecological Sciences. The results of a research carried out using questionnaires, with 30 students of Agrarian Sciences (Agronomy, Veterinary Medicine, Zootechnics and Post Graduation in Rural Extension) of the Federal University of Santa Maria-Rs/Brazil, perceptions about the functionality of audiovisual in teaching-learning. The perceptions point to the acceptance of the audiovisual as an important mediator of teaching, as it is a tool capable of giving visibility to local and regional experiences, allowing, even if virtually, exchanges of knowledge and experiences, since the senses remain stimulated through sound, images in shared movements and emotions. The results still point to the need to revise teaching practices and the epistemological bases where the Agricultural Sciences are anchored, since contemporaneity requires new positions for the formation of professionals capable of contributing to Sustainable Development, based on social equity, traditional knowledge, ecosystem equilibrium and the autonomy of subjects.
