Critérios de avaliação para videoaulas na sala de aula invertida: o caso do ensino sobre semelhança de triângulos na preparação para o exame nacional do ensino médio

Abstract

This Course Final Work - CFK addresses the theme of use of video classes in Mathematics in the inverted classroom methodology. The general objective is to create criteria to analyze the potential and limitations of a video lesson on similarity of triangles in a proposal of an inverted classroom for mathematics classes. The motivation for this CFK came from his experience as a teacher and channel owner of the RK Mathematics pre-university course. It is a research with a qualitative approach, exploratory regarding the objectives and a case study for the collection of information. For this, we have theoretical references that discuss the Inverted Classroom - SAI, about or hybrid teaching, in video-class and video. We also carry out consultations on the Youtube platform to survey possible criteria as well as video classes on similarity of triangles available. These references provide support for the elaboration of criteria. We created 7 criteria organized in the technical dimension (3 criteria that are related to image and audio quality, lighting and video editing), mathematics (2 criteria, that is, the knowledge of the mathematics teacher and the systematic organization of the content presentation) and the dimension (2 criteria, teacher use of technologies for teaching, relationship of video with face-to-face/hybrid classroom and video time. After this step of surveying criteria for creating and evaluating a video class, we started to create a video - classroom of the RK channel on similarity of triangles followed by its implementation in the SAI methodology in a hybrid model similarity of triangles from two raised criteria Finally, we end by reflecting on the need to continue the research as it tests two criteria and production of more material on the subject due to the scarcity of material for studies and research by mathematics teachers.
