SUMMARY:

The teaching of thermochemistry is one of the main challenges for the Chemistry teachers, since it involves a series of difficulties described in literature. We bring a pedagogical proposal for this theme with the use of experimentation and video production, seeking to stimulate students to make experiments and develop their knowledge, using digital technologies of which they naturally have some skill, allowing to minimize considerably the diversity observed in the classroom, for a better participation, commitment and collaboration. During this work we developed an application as an educational product, which focuses on didactic guidelines for secondary school teachers. The participants of the investigation were the students of a high school and technical of School Professional Prof. Walquer Cavalcante Maia, located in the city of Russas-CE. Seven meetings were necessary for application, involving the capture of previous conceptions, illustrative experimentation, dialogical exhibition of concepts, classroom activity, execution of experiments in the laboratory, production and editing of videos by students, exhibition and evaluation of the teaching proposal applied. The results of the approach have highlighted a promising strategy. There was dedication through a more active participation, with a constant stimulus that provided autonomy and this favored the changes of the participants in the procedures for experiences and video production, also allowing the cooperation between those who presented more and less difficulties in the proposed activities. Their previous content presented in the great majority, a confusing relationship between the phenomenological and theoretical levels of knowledge. The responses after watching the videos showed progress in the macroscopic aspect, by making better interpretations of the studied phenomena. In the classroom activity, we were able to explore the representative aspect in terms of identification and understanding of thermochemical equations and enthalpy diagrams. In the evaluation of the teaching proposal, we did not find any discordant answer regarding the understanding of the chosen strategy.
