O percurso da didatização do pensamento algébrico no ensino fundamental: uma análise a partir da transposição didática e da teoria antropológica do didático / The route of the didactization of the algebraic thinking in the elementary school: an analysis from the Didactic Transposition and the anthropological theory of didactic

Marcia Aguiar 18 December 2014 (has links)
O ensino de álgebra nos três últimos anos do Ensino Fundamental tem se reduzido a um momento destinado ao treino e à fixação de regras e procedimentos algébricos. Ao que parece, os livros didáticos corroboram com essa visão do ensino de álgebra. Por outro lado, sabemos que no livro didático estão presentes algumas intenções didáticas legitimadas, de certa forma, por todos aqueles que participam do processo de ensino. Ao professor, que muitas vezes só possui o livro didático como material para preparar as suas aulas, cabe transformá-lo no saber que será ensinado na sala de aula. A álgebra é uma ciência ensinada predominantemente na escola e é relevante para capacitar os sujeitos a compreender o desenvolvimento científico e tecnológico atual. Por isso, parece-nos que o ensino de álgebra nos 7º, 8º e 9º anos do Ensino Fundamental deveria contribuir para a construção de um pensamento algébrico, superando as práticas rotinizadas. Assim, o objetivo do nosso trabalho é analisar de que modo os livros didáticos desse nível de ensino permitem a construção do pensamento algébrico. Ou seja, investigar o percurso de didatização da álgebra no Ensino Fundamental ou, mais propriamente, nos livros didáticos. Para essa análise utilizamos a Teoria da Transposição Didática e a Teoria Antropológica do Didático, propostas por Yves Chevallard. Essas teorias propiciaram uma análise mais aprofundada sobre os materiais e também demonstram ser uma ferramenta consistente para auxiliar o professor na sua prática pedagógica. Analisamos três materiais pedagógicos: dois livros didáticos, que vieram da lista de livros aprovados no PNLD-2011 e o Caderno elaborado pelo governo do Estado de São Paulo proveniente da proposta São Paulo Faz Escola. Com essas análises conseguimos perceber que a programabilidade do saber legitimada pela noosfera impossibilita muitas inovações na didatização referente ao ensino de álgebra, e que alguns livros ainda mantêm o ensino de álgebra voltado para o treino de procedimentos e resoluções. Por outro lado, também conseguimos encontrar outros percursos de didatização nos quais está presente um ensino voltado para o desenvolvimento do pensamento algébrico. / The teaching of algebra in the last three years of elementary school has been reduced to a point aimed at training and to set rules and algebraic procedures. Apparently, textbooks corroborate this view of teaching algebra. On the other hand, we know that in the textbook are didactic intentionalities, in a way, to all who participate in the teaching process. In the teacher, who often only have the textbook and material to prepare their lessons, will lie the responsability to turn it in the knowledgment which will be taught in the classroom. Algebra is a science predominantly taught in the school and it is relevant to enable the students to understand the current technological and scientific development. Therefore, it seems that the teaching of algebra in 7th, 8th and 9th grades of elementary school should contribute to the construction of an algebraic thinking, overcoming the routinized practices. The objective of our work is to analyze how that grade level books allow the construction of algebraic thinking. In other words, to investigate the route of didactization algebra in elementary school or, more properly, in textbooks. For this analysis, we will use the theories of Didactic Transposition and Anthropological Theory of Didactic proposed by Yves Chevallard. These theories provided a deeper analysis of the materials and also prove to be a consistent tool to assist teachers in their teaching. We analyze three teaching materials: two textbooks, which came from the list of approved books in PNLD-2011 and the Booklet prepared by the state government of São Paulo from the proposed São Paulo Faz Escola. With this analysis we can see that the programmability of knowledge legitimized by the noosphere prevents many innovations in didactization concerning the teaching of algebra and some books still keeps teaching algebra facing the training procedures and resolutions. On the other hand, we did find other paths of didactization in which an education directed to the development of algebraic thinking prevails.

When we talk about elementary school and high school researchers consider textbooks as being the main resource used by teachers in the classroom scenario. With this focus in mind we decided to assess this approach on the affine function carried on in mathematics books in the 9th grade of elementary school and the 1st year of high school. In order to have an idea about what is being produced in the educational field in Brazil we analyzed some researches that deal with the affine function. Based on the analysis result we summarized some of the difficulties presented by the students, in the grades mentioned above, who participated in those researches had to face and deal with the affine function. We observed that difficulties to analyze and build the function of the graphic of the affine function occurred with both elementary and high school students. It was also confirmed that the approach on the affine function in four textbooks assessed during the research were not enough to overcome some of the difficulties pointed out in the research. To increase knowledge on the case study we also investigated a sequence about the affine function carried out on the UFRPE’s science teaching post graduation program. We decided to analyze the textbooks and the didactic sequences because we wanted to know what were the common aspects between them and what were the outcomes. To achieve this goal, we used as analyzing tool the didactic anthropological theory on workbooks that provided us with the praxeology knowledge to guide us in order to achieve our objectives. This way we carried an praxeological analysis in the activities proposed by textbooks and didactic sequences. As analyzing tools, we adopted the mathematics praxeology notion proposed by Chevallard in the anthropological textbook theory. It was confirmed that there are some major divergences among textbook approaches and the didactic sequences. It was also confirmed that textbooks emphasize more practical aspects related to technical mathematics praxeological blocks, as opposed to the aspects related to the technological theoretical ones. As a result of this research, we present some results about affine function teaching that will be able to support forthcoming researches as well as help teacher have a more accurate view towards all the activities and approaches in textbooks. / No contexto da educação matemática, algumas pesquisas têm mostrado que os estudantes dos ensinos fundamental e médio possuem dificuldades quando estão trabalhando com situações que envolvem a função afim. Quando falamos dos ensinos fundamental e médio, vários pesquisadores consideram o livro didático como sendo o principal recurso utilizado pelo professor em sala de aula. Nesse sentido, nos propomos a analisar as abordagens de função afim realizadas em livros didáticos de matemática do 9º ano do Ensino Fundamental e do 1º ano do Ensino Médio. Para termos uma ideia sobre o que está sendo produzido na área de educação matemática no Brasil, analisamos algumas pesquisas que trabalharam com a função afim. Com base nessa análise, fizemos uma síntese das dificuldades que os estudantes dos ensinos fundamental e médio, que participaram dessas pesquisas, enfrentaram ao lidarem com a função afim. Verificamos que dificuldades para analisar e construir o gráfico de função afim ocorre com alunos, tanto do Ensino Fundamental como no Ensino Médio. Também constatamos que as abordagens sobre função afim nos quatro livros didáticos analisados não dão conta de superar parte das dificuldades apontadas nas pesquisas. Para aprofundar nosso estudo, analisamos também uma sequência sobre função afim desenvolvida no Programa de Pós-Graduação em Ensino de Ciências da UFRPE. Optamos por analisar os livros e a sequência didática porque queríamos saber quais eram os aspectos comuns entre as abordagens dos livros didáticos e da sequência didática. Para isso utilizamos como ferramenta de análise a Teoria Antropológica do Didático que com a noção de praxeologia nos deu subsídios para alcançarmos nossos objetivos. Desse modo, fizemos uma análise praxeológica das atividades desenvolvidas pelos livros e também pela sequência didática. Como ferramenta de análise adotamos a noção de praxeologia matemática desenvolvida por Chevallard, na Teoria Antropológica do Didático. Constatamos que existem divergências entre as abordagens dos livros didáticos e da sequência didática. Verificamos ainda que os livros didáticos dão mais importância aos aspectos relacionados ao bloco prático técnico da praxeologia matemática, em detrimento dos aspectos relacionados ao bloco tecnológico teórico. Com essa pesquisa, apresentamos alguns resultados sobre o ensino de função afim que podem subsidiar pesquisas futuras, bem como o professor a ter um olhar mais atento às abordagens propostas nos livros didáticos.

The study is an introduction to the topic and leads the reader to understand that the notorious Euler Relation if inadequately presented, is not sufficient to establish the existence of a polyhedron. For analyzing some examples, the text inserts the idea of doubt, showing cases where it is not fit enough numbers to validate the Euler Relation. The research also highlights a theorem certainly unfamiliar to many students and teachers to research the polyhedra, presenting some very simple inequalities relating the amounts of edges, vertices and faces of any convex polyhedron, which clearly specifies the conditions and sufficient necessary for us to see, without the need of viewing the existence of the solid screen. And so we can see various polyhedra and facilitate understanding of what we are exposed, we will use Geogebra, dynamic application that combines mathematical concepts of algebra and geometry and can be found through the link http://www.geogebra.org / Neste trabalho, analisamos a Rela??o de Euler de uma maneira geral, utilizando, como meios de visualiza??o, a manipula??o de materiais concretos, a fifim de que haja maior facilidade na percep??o do conte?do, expandindo a aprendizagem aos alunos de n?vel m?dio e at? fundamental. O estudo faz uma introdu??o ao tema e leva o leitor a entender que a Rela??o de Euler, se apresentada de maneira inadequada, n?o ? sufificiente para determinar a exist?ncia de um poliedro. Pois, analisando alguns exemplos, o texto insere a id?ia de d?vida, mostrando casos onde n?o ? sufificiente encaixar n?meros que validem a Rela??o de Euler. A pesquisa destaca ainda um teorema, certamente desconhecido de muitos alunos e professores que pesquisam sobre os poliedros, apresentando algumas inequa??es muito simples, relacionando as quantidades de arestas, v?rtices e faces de qualquer poliedro convexo, as quais definem de forma precisa as condi??es sufificientes e necess?rias para que possamos constatar, sem a necessidade da visualiza??o, a exist?ncia do s?lido em tela. E para que possamos visualizar v?rios poliedros e facilitar a compreens?o do que estamos expondo, utilizaremos o Geogebra, aplicativo de matematica din?mica que combina conceitos de geometria e alg?bra e pode ser encontrado por meio do link http://www.geogebra.org

Effects of Direct Instruction Common Core Math on Students With Learning Disabilities

Monye, Joseph Ifeanyi 01 January 2016 (has links)
U.S. students with learning disabilities' math skills acquisition has been on the decline in recent years. Studies show that teachers using traditional methods of teaching math lack knowledge of task analysis, chunking, sequencing, mass practice, modeling, and repetition of instruction. These components of direct instruction or pedagogical activities are hallmarks of special education teaching and are collectively described as cognitive support pedagogy. The study evaluated direct instruction teaching strategies to teach Common Core math to middle school students with learning disabilities, to determine if the current downward trend in math skills acquisition amongst them can be reversed. The theoretical framework of this study was based on Watson's theory of behavioral psychology as it applied to learning and teaching. The participants consisted of a convenience sample of students with learning disabilities. The study used a Solomon 4-group experimental design, in a series of two One-way ANOVAs to measure differences in math score by intervention for pretested and for non-pretested students, with one Factorial 2 X 2 ANOVA which measured for differences by interaction between pre-testing and intervention. Results of ANOVAs were significant at the α-levels of .05 (F (1,78) = 233.66 p < .001), indicating that significant differences existed in math scores of pre-tested students who received intervention and those who did not. The study is significant to teachers, curriculum developers, and instructional leaders because it is the first study of its kind to measure the outcomes of Common Core math using direct instruction and it points a way forward to creating positive social change by increasing students' graduation rates and promoting students' engagement in school and beyond.

Text in Afrikaans / Die doel van hierdie navorsing was om vas te stel of leerders in Graad R die nodige wiskundige vaardighede deur gestruktureerde spel bemeester het wat as grondslag vir verdere wiskunde-onderrig kan dien. In die literatuurstudie is die verskillende wiskunde konsepte in diepte ondersoek. Daar is ook gefokus op die oordra van wiskunde konsepte aan jong leerders. Verder is daar in die literatuurstudie ondersoek ingestel na die doel, waardes, tipes, ontwikkeling van spel asook spel in die moderne era. Vir die empiriese ondersoek is 103 Graad R-leerders van ses verskillende skole betrek. Daar is gebruik gemaak van ʼn ewekansige steekproef by die skole wat bereid was om aan die studie deel te neem. Die ondersoek het plaasgevind deur die gebruik van die positivistiese kwantitatiewe navorsingsmetode. Daar is gebruik gemaak van vraelyste om te bepaal wat die bemeestering van wiskundige vaardighede by Graad R-leerders is. Gestruktureerde spel is as hulpmiddel gebruik vir die insameling van die navorsingsmateriaal. Die resultate is bekom deur die vraelyste statisties te verwerk. Daar is ook vraelyste aan die onderwysers gegee om meer agtergrond oor hulle onderrigmetodes asook die onderwysers se eie gevoel teenoor en kennis van wiskunde te bekom. Die navorsingsresultate bevestig dat die meerderheid van die Graad R-leerders oor ʼn goeie wiskundige grondslag beskik. Dus is daar deur die studie gevind dat dit belangrik is dat jong kinders baie moet speel om nuwe vaardighede aan te leer, maar ook die geleentheid moet hê om die vaardighede te beoefen. / The purpose of this research was to determine whether learners in Grade R mastered the necessary math skills through structured play that could serve as a basis for further mathematics training. In the literature various math concepts were studied in depth. The main focus was on the transfer of math concepts to young learners. The literature study further focussed on the purpose, values, and types of play, development of play and play in the modern era. An empirical study using random sampling was done using 103 Grade R learners from six different schools who were willing to participate in the study. The study was done using the positivism quantitative research methodology. Questionnaires were used to determine the mastery of mathematical skills by Grade R learners. Structured play was used as a tool to collect the research material. The results were obtained by processing the questionnaires statistically. Questionnaires were also completed by the teachers to confirm their background knowledge, teaching methods as well as to determine the teachers‟ own feelings towards and their knowledge of mathematics. The research results confirm that the majority of Grade R learners have obtained a good math foundation. The study also confirmed that it is important that young children need to play to learn new skills and must have the opportunity to practise the new skills. / Psychology of Education / D. Ed.
