Seeds that germinate, sprout, grow and develop in their own time: productions of educational actors inserted in different spaces

Resumo

As part of the “Digital Videos in Mathematics Education” extension course, we aimed to understand how the discourse of a teacher combines semiotic resources in the video production entitled “About the sphere and the cylinder”. The research approach is qualitative, and the data produced in the investigation is based on the video, on interviews, and on discussion forums. We reflect on spontaneity, the classroom, and the use of digital technology, creating a link between the spreading of seeds and the possibility of exploring this technology in public schools to stimulate students to produce mathematical knowledge through videos. In this sense, when we became aware that our reflections touched the sensibility of the teacher, we oriented the investigation to the product of his experience in the light of multimodality. We conclude that this educational actor, guided by “playfulness” and “valid information”, harmonizes semiotic resources of language, mathematical symbolism, and visual demonstration when producing meanings in his discourse.
