NOX ROOL: A CHEMICAL ACTIVITY IN CHEMISTRY IN THE CONTENT OF OXIDATION NUMBER

Abstract

The use of didactic games in Chemistry classes is a challenge for all the teacher of this area of ​​knowledge, since it aims at a bridge between play and theory, facilitating and creating an environment conducive to knowledge. Thus, the game "NOX roulette" was created, where it aims to identify the Oxidation Number (NOX) of each chemical element, that is, simple and compound substances so that the students understand this theme in a playful way. We use as orientation to build this game the studies of Fonseca (2016). This research shows the preparation to the experience of a didactic game, entitled "NOX roulette" using as methodology the CEK (Kellyana Experience Cycle) proposed by George Kelly (1963). This game is aimed at high school students in the content of Oxidation Number. This didactic resource was created International Institute Awakening Vocations (IIDV) linked to the International Program Awakening Vocations for Undergraduate Courses (PDVL) articulated to the Working Group (GT) of Didactic Games in the Teaching of Chemistry, and the experience was realized in a class of 2º year of the High School, in which she is a partner of the program, in the city of Recife - Pernambuco. Thus, the Kellyana experiment cycle (CEK), which is based on George Kelly's Theory of Personal Construsions (1963), was used as a methodological framework. In this experience, it was undeniable that about 82% of the students answered questions about NOX. From the results of this work, it is possible to emphasize that the students have the opportunity to actively participate of all the activity, making use of their previous knowledge, realizing reflections and discussions with the colleagues and the teacher favoring the interaction student-student and student -teacher.
