Caminhos da reação: uma sequência didática para o processo de ensino e aprendizagem de taxa de desenvolvimento da reação. 2019. 153f.

For these reasons, it is essential to seek didactic resources that enable the improvement of the understanding of the concepts of this discipline. In this sense, this work aimed to develop a didactic sequence on the reaction rate content, from different strategies, such as textbooks, videos, newspaper and magazine news, Phet simulator, experimentation and space for dialogue, which address food, environment, fuel chemistry and catalysis issues. In addition to encompassing expository strategies, this proposal also developed an educational game as a tool to aid the process of teaching and learning in chemistry. The research was characterized as qualitative and the choice of the theme, reaction rate, was due to the difficulties of understanding regarding the contents already existing in the literature due to the use of traditional methodology. The work was applied in two classes of the second grade of high school, and starting with a didactic sequence of four blocks, two classes in each block, making a total of eight classes. At the end of the blocks the didactic game was applied, which allows the student to acquire knowledge through alternative methods to the traditional teaching models, incorporating playful characteristics of the games to the concepts and contents and allowed the teacher to evaluate the content worked. Data were collected through recordings (audio and video) made in the classroom, field diary and forms. For data analysis and treatment, the data triangulation technique was used, which aims to cover the maximum amplitude in the description, explanation and understanding of the focus in study, in qualitative research. It was possible to identify the previous knowledge of the students and, thus, use strategies, tools and educational objects allied to the themes (food, environment, fuel chemistry and catalysis) used in the didactic sequence, which enabled motivation both in the game and in class to discuss the four themes. The interaction between student-students and student-teacher provided by the game was intense, as well as in the problem situations created in class. The playful stood out, especially in the game, which presented a lot of fun and pleasure. During the application of the game it was possible to observe the great relationship that the game had with the content worked in the classroom. This work allowed the students, during the application of the didactic sequence and the game, to establish and relate the concepts of the reaction rate content, based on the problems and questions about the themes involved. An educational product, which is the didactic sequence, was designed for the reaction rate content.Acesso AbertoSequência didáticaJogo didáticoCaminhos da reaçãoTaxa de reaçãomasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::QUIMICA
