- ItemEnsino de probabilidade : uma proposta de sequência didática com uso dos jogos Bozó e Coup(Universidade Federal de Mato Grosso, 2021-12-06) Alves, Luis Paulo de Souza; Rodrigues, Eunice Cândida Pereira; 468.790.641-91; http://lattes.cnpq.br/9037151037918091; Rodrigues, Eunice Cândida Pereira; 468.790.641-91; http://lattes.cnpq.br/9037151037918091; Silva, Clayton Eduardo Lente da; 297.022.948-00; http://lattes.cnpq.br/4069908956291996; Dias, Ivonildes Ribeiro Martins; 961.058.951-00; http://lattes.cnpq.br/8664599889120339Didactic sequence is an important tool for organizing educational practice, it guides and systematizes such practice. Because of this, it is necessary that this instrument adapts at students’ demands, and one of these demands is that knowledge be practical and part of their daily lives. In this regard, the use of games presents itself as an important tool to be able to make an approximation of mathematical concepts, in this case concepts of probability, daily life, and for being inserted in a playful way, sharpening student’s curiosity. The main objective of this research is to verify if the use of the Bozó and Coup games for the preparation and application of a didactic sequence on probability facilitates the understanding of the worked concepts. For this purpose, a thematic approach was formulated following the guidelines of the Common National Curriculum Base (BNCC) and, according to its requirements, a didactic sequence was structured and applied using the aforementioned games with students from a 9th grade class of elementary school at Leibniz School from Rondonópolis. After the application, a qualitative research was carried out using the technique called heremeneutic-dialectic circle of data collection, through an oral presentation of their evaluation of the didactic sequence and learning itself, answering individual questionnaires with the same regards, and through the analysis of the answers of the activities carried out by those involved. It was found that the use of games contributed in a positive way, which can be verified mainly by the greater involvement of students, by verifying the practice of writing activity with games still in hand, and by the untying of problem solving with ready-made formulas.
- ItemModelos matemáticos de equações diferenciais aplicados ao estudo da pandemia de SARS-CoV-2(Universidade Federal de Mato Grosso, 2021-12-09) Silva, Fabrício Onório da; Silva, Clayton Eduardo Lente da; 297.022.948-00; http://lattes.cnpq.br/4069908956291996; Silva, Clayton Eduardo Lente da; 297.022.948-00; http://lattes.cnpq.br/4069908956291996; Rodrigues, Eunice Cândida Pereira; 468.790.641-91; http://lattes.cnpq.br/9037151037918091; Gouveia, Márcio Ricardo Alves; 257.244.268-03; http://lattes.cnpq.br/7578944173575239This work presents a study on applications of Ordinary Differential Equations to Epidemiology. We analyze the behavior of some epidemiological models using the concepts of the Qualitative Theory of Differential Equations. In particular, we analyzed the epidemic caused by the SARS-CoV-2 virus, which causes the COVID-19 disease, in the city of Rondonópolis. Therefore, we study the main concepts involved in the modeling process, in addition to demonstrating mathematical results that corroborate the statements generated by the proposed models. Finally, based on the studies carried out, we discuss the importance of teaching the exponential function for high school students.
- ItemO uso do GeoGebra para o ensino do cálculo da área de polígonos no ensino fundamental(Universidade Federal de Mato Grosso, 2021-09-24) Gonçalves, Lilian da Silva; Oliveira, Joelma Ananias de; 897.514.501-87; http://lattes.cnpq.br/0370758268194196; Oliveira, Joelma Ananias de; 897.514.501-87; http://lattes.cnpq.br/0370758268194196; Santos, Dércio Braga; 297.022.948-00; http://lattes.cnpq.br/7566907783145556; Lima, Leandro Bezerra de; 276.630.588-28; http://lattes.cnpq.br/3605569619458324The indices in mathematics, presented by national evaluations are not favorable, in the classroom it is possible to notice the difficulty of students in understanding mathematical subjects, configuring important research and discussion on methods of teaching the discipline, even more at this time of COVID-19 pandemic that the world faces and has direct reflections on school education. Thus, the general objective of this study is to develop a collection of interactive activities on GeoGebra, which helps elementary school teachers to demonstrate formulas used in the calculation of the area of polygons. To achieve the outlined objective the methodological path followed by this study was the realization of a research of applied nature; qualitative approach; as for the objectives it is exploratory; in relation to the procedures it is a bibliographic research with inductive method. Through the development of this research it was possible to know some features of GeoGebra, such as the use of the application for graphical representation of function, discussion on solving linear systems, the mutual contribution between members of the GeoGebra community and the collaborative development available through the software. In terms of dimension the material produced is a prototype of a book that is divided into three sections, the first contains applications for the use of the teacher in the classroom, in order to facilitate the demonstration of the formulas for calculating the area of polygons and provide a tool that facilitates the visualization and understanding of the formulas by the student. The second section has practical activities for memorizing the calculation processes, and the third section presents problem solving exercises. By being in possession of a published material the user can access the creator's profile, search for the post and make comments, criticisms or submit a change suggestion. It was concluded that the elaboration of a collection of interactive activities in GeoGebra, which helps the elementary school teacher to make the demonstrations of the formulas used in the calculation of the area of polygons was developed and presented in the research results, proving that the work achieved its main objective.
