Proposta de atividades para o ensino de trigonometria / Proposed activities for teaching trigonometry

Francisco Delmar Pinheiro de Sousa 15 May 2014 (has links)
CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Este trabalho relata a experiÃncia de aplicaÃÃo em sala de aula de uma sequÃncia de atividades de trigonometria com destaque para a construÃÃo, estudo e utilizaÃÃo de um ciclo trigonomÃtrico ou prancha trigonomÃtrica numa turma de 2 ano TÃcnico em ComÃrcio (em nÃvel mÃdio) de uma escola profissional da rede estadual de ensino do estado do CearÃ. As atividades aplicadas constam de estudo de semelhanÃa de triÃngulos, das razÃes trigonomÃtricas no triÃngulo retÃngulo e das funÃÃes circulares seno, cosseno e tangente facilitadas por sua vez, pelo manuseio da prancha trigonomÃtrica. A avaliaÃÃo dos resultados do trabalho se dà atravÃs do acompanhamento das facilidades/dificuldades encontradas pelos alunos na confecÃÃo dos materiais e na resoluÃÃo das atividades propostas. / This paper reports the experience of the application in the classroom of a sequence of activities trigonometry with emphasis on the construction, study and use of a trigonometric trigonometric cycle or board in a class of 2nd year in Technical Trading (medium level) a professional state school education in the state of CearÃ. The activities listed in the applied study of similar triangles, the trigonometric ratios in right triangle and circular functions sine, cosine and tangent facilitated in turn by the management of trigonometric board. The evaluation of the results of the work is through the monitoring of the facilities/difficulties encountered by students in the preparation of materials and the resolution of the proposed activities.
