Cloroplastos: uma análise nos livros didáticos de ensino médio

Abstract

Based on the experience of high school public schools in the city of Fortaleza, it was noticed a great difficulty of the students in the topic that talks about chloroplast and photosynthesis of plants, this problem is caused by several reasons related to the educational system. Biology is an experimental science that requires the student to have contact with what is taught, the only contact the students of this school had with this subject was through the textbook used in the classroom. The textbook has dominated the school environment by becoming the main method of study in schools, it is used by students and teachers in study and in educational practice. It is important to remember that this book has undergone many modifications over the years, in its text, its structure and its method of approach. The Brazilian government, in 1985, created the National Textbook Program (PNLD) to invest, facilitate and organize the distribution of these books in education. But in addition to investing in these books it is necessary to improve the educational method. In this work, through the application of a questionnaire with teachers of biology in public schools and later were analyzed textbooks of different periods, he problem of textbooks in schools and the approach to the subject of chloroplasts in books and in the classroom were studied. Through the results of this research we observed difficulties in the educational method, in the choice of books used and in the teaching and learning process.
