Dificuldades inerentes à compreensão e resolução de problemas envolvendo as leis de Newton

Abstract

This dissertation was prepared from an applied research in a public educational institution with the first year high school students, in which we sought to investigate the mistakes made by students with regard to the study of textbook use to develop the laws of Newton. The theme is very relevant therefore is commonly reported that a portion of students do not understand the concepts related to this topic and as a consequence can not solve exercises on the topic. Evidence of the work presented here, show that the textbook when he makes use of inappropriate language in the concepts approach contributes to the spread of the difficulty of learning in relation to Newton's laws, making the resolution of exercises related to the subject becomes-a difficult difficult to overcome. In the introductory chapter, raised some hypotheses to the difficulty of understanding the study of Newton's laws of physics and the study of the context. For the construction of the theoretical framework discussed the significant learning, the role of the textbook in the teaching-learning process and the training of teachers in Brazil. Chapter three discusses the approach used to conduct the survey, while the fourth chapter presents the analysis and discussion of results. For construction of the research was used an online questionnaire (google drive) applied after the subject to be taught by graduate student in class into two groups, one control group and one evaluated. In one of the two first-year high school classes, the class was given an expository manner with reference to the methodology used by a textbook widespread adoption in the country, while in a second, the lesson was presented using as reference the support material called educational product (suggested in Appendix b of the work). Evidence points to the effect that the use of inappropriate language commonly used by some textbooks, has significant reflection on the difficulty of understanding of the laws of Newton. The methodology suggested in the study of this topic in this study (called educational product) indicates that the use of more cohesive language and the application of more appropriate examples seems to provide a better level of understanding of the students.
