Possibility of using Information Literacy, Mathematical Literacy and Problem-Solving methodology to teach mathematical concepts related to the contents of Spatial Geometry and Matrices to High School students

This research aimed to investigate methodological possibilities for teaching Mathematics, in High School, based on the triad Informationl Literacy, Mathematical Literacy and Problem-Solving methodology. To this end, it was carried out bibliographic and field research, with predominantly qualitative results. The suggested methodological proposal was validated with 2nd year high school classes of a public school in Alexânia (GO). In the proposed approach, the teacher acted as a mediator of the teaching and learning process, and it was noticed that the research practice in the classroom served as a foundation for the construction of new concepts. The proposed problems were starting points, that is, introductory to the contents covered in the didactic sequences and did not aim at fixing or finalizing a content. We emphasize that Information Literacy directly influences the achievement of Mathematical Literacy, which is about giving students subsidies to understand mathematics in the modern world.
