Vitamina C – contextualização e interdisciplinaridade no ensino de química.

Abstract

The contextualization and interdisciplinarity in teaching chemistry are proposed to approximate the context in which the student is inserted, taking into account their culture, ethical and human values. Thus the teaching of chemistry can not just be restricted to lectures that emphasize memorization of facts, laws and theories that are unrelated to the socio-cultural background of the student. In this sense, it is necessary to insert pedagogical proposals that address the contextual ization and interdisciplinarity in teaching chemistry. The use of teaching by projects where it addresses socially relevant topics, represent great potential for contextualizing the chemical knowledge. In this context, this work presents a project that aimed to address the interdisciplinarity and the contextual ization in teaching chemistry, using as a motivating theme Vitamin C, emphasizing fruits grown in the region. The project development environment was the State Preparatory High School Innovative Orlando Venancio dos Santos, located in Cuite-PB. The survey was conducted in the second half of 2014. In this been involved students of two classes of the second year, adolescents of both sexes in the age range 16-18 old, living in urban and rural areas. The project was developed through stages where they presented various activities, which were incorporated into lectures, field class and experimental classes, where they sought to promote contextualization and interdisciplinarity of content inherent to the topic Vitamin C. Evaluation of project was done through the application of four questionnaires, where they had objective and subjective questions that were directed exclusively to students. From the analysis of the questionnaires, it was found that the teaching for or ot project design in line with the interdisciplinarity and the contextualization, contributes to the understanding of various concepts that are related to the theme vitamin C, especially the chemical concepts.
