Aplicação de estudo de caso com o tema tabagismo no ensino médio de química

Abstract

The work carried out is related to the application of a methodology of resolution of case study in the classroom.The method was applied in a public school in a 3rd year high school class in the city of Bagé, State of Rio Grande do Sul. The activity was developed through the application of three case studies relating questions about smoking and its consequences. Seeking to make known the main toxic substances contained in the cigarette and the health damage of active and passive smokers due to the permanence in tobacco smoke.The research was carried out in a regular teaching group, with approximately 21 students, who were submitted to eight meetings to solve the activity. We adopted different means to carry the necessary information so that the students had access to information that would allow developing the proposed activity. Such as investigative questionnaires, lectures, videos, experimentation and presentation.The use of investigative cases is viewed with good eyes by many teachers, because it allows approaching diverse social, cultural and environmental themes in the classroom, increasing the knowledge of the student and making significant learning. As results, we believe that the present work contributes to the strengthening of the contents learned, since it contributes to the development of critical thinking and the student's decision making in face of real situations that can be found in the student's daily life, helping in the teaching and learning process.
