Ensino de química em contextualização: uma proposta de aula sobre tabela periódica para os estudantes do ensino médio do IFPI campus – Cocal

Abstract

The improvement of chemistry teaching should be related to the difficulties experienced in the students' day-to-day life. Thus, building proposals that aim to help students understand the environment in which they are inserted can contribute to better learning. In view of the absence of dialogue and decontextualization in chemistry teaching, it aims to make a class as a facilitating strategy for the teaching of periodic table based on the contextualization with culture and challenges of young students of the integrated high school of IFPI Campus Cocal, in the classes of 1st, 2nd and 3rd year of administration. The research took place in five parts, at first the questionnaire was applied to identify the areas of greatest difficulty, the second step was the bibliographic research of the textbooks, in the third moment, the application of a questionnaire related to the content that was goin to be taught and then, the execution of a contextualized class on the content of Periodic Table, the fourth moment was the application of the post-questionnaire, and the fifth moment was the construction of a chapter of a book on the content studied. In which, it is observed that after class, on average more than 70% of the students in the three classes were able to correctly answer the questions of the post-questionnaire. Therefore, it is valid to state that the application of the contextualized class, using a didactic material was effective for the development in the learning teaching process
