Resumen
The teaching and learning process in Chemistry is still considered a great challenge for
many teachers who live with the difficulties faced by the student, since its content is
characterized by the high degree of complexity and difficulties of comprehension. 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.
