Material manipulável e manipulável virtual para o ensino de estimativa de proporção populacional na formação inicial de professores

Abstract

This work aimed to evaluate how the 3rdgrade students in a Mathematics Degree course judge, conceptualize or qualify the use of manipulable material and virtual manipulable for the Population Proportion Estimate Teaching. In order to meet this target, an applied qualitative research was developed and then organized in 4 steps: 1-Theoretical framework production to verify situations of Statistics contents Teaching in the Basic Education; 2-Search for materials for the Population Proportion Estimate Teaching, in which the manipulable material elaborated by the professor Lisbeth Kaiserlian Cordani was found and for the lack of existent technological resources the researcher developed a virtual manipulable in partnership with a student of the Computer Science course of Universidade Estadual do Norte do Paraná; 3-Intervention or application of the research, it refers to the application moment ofthe materials mentioned on the step 2 in a 3rdgrade class of a Mathematics Degree course where data were collected, 4-Data collection analysis, in which the Discursive Textual Analysis based upon Moraes and Galiazzi (2016) was used. Through data analysis, it was possible to observe that the students approve the use of manipulable material and virtual manipulable for the Population Proportion Estimate Teaching, beacuse: they help the teacher in the teaching process, they facilitate a contextualized teaching applied to the students’ reality, they provide a connection between the theoretical and practical knowledge and they contribute positively to the graduation of mathematics teachers when these ones get to know these materials still during the graduation course, stimulating them to develop the content futurely in the Basic Education.
