This work aims to assist the Geometric Progression Content Learning, developing educational material supported by research methodology called didactic engineering. We developed an instructional sequence based on a problem situation, in which students, by providing a simulation of a polluted river, should predict the time needed for the de-pollution to occur and develop a mathematical model in order to explain this phenomenon. The work was applied in a Ninth Grade classroom (Junior High School) in the State School called Victor Maida in Ibitinga with 29 students divided into trios. These trios remained together until the end of the application of the instructional sequence, which lasted five days. The sequence contained about 60 questions, which were formulated into a form with which the student could act autonomously, with minimal teacher intervention. Finally, this work was based on the collection of results in the analysis of priori and a posteriori of the responses provided by the teams, in order to check the results obtained.
O ensino e a aprendizagem da análise combinatória dentro do contexto de telefonia
(Universidade Federal de São Carlos, 2013-08-17) Fusel, André Thiago; Costa, Ivo Machado da; https://lattes.cnpq.br/1111331485581633; https://lattes.cnpq.br/4530476750103140
This present dissertation, structured in the methodology of well-known research as Didactic Engineering, it presents the development of an unpublished class for the teacher on combination analysis in the High School. The objective of this work is to elaborate a didactic material that aids the students in the learning of some concepts of combination analysis in a significant way. The elaborated didactic sequence is inserted in the telephony context and it approaches the current subject on the increment of the 9th digit in the numbers of cellular of the area of the State of São Paulo with code of area 11. The whole sequence was thought so that the student will be the protagonist of its learning, making observations, you conjecture, debating with the colleagues, manipulating materials and solving the problems proposed in the leaves of activities in an autonomous way. The didactic sequence was applied for two groups of 2nd year of the High School in the School Educational Center SESI Bragança Paulista. For they accomplish the activities, the students were divided in groups. All the sheets of activities accomplished by the students and the registrations of observations facts by the teacher during the application of the activities were good as tools to verify the objective plans were reached.
