The aim of the study is to investigate pre-service middle school mathematics teachers&rsquo / critical thinking processes through statistical and probabilistic knowledge in the context of popular media texts. The study was conducted with a qualitative case study method. Participants of the study consisted of four senior pre-service middle school mathematics teachers enrolled in a public university. Data were collected through in-depth interviews with the participants. Analysis of the data was conducted on the basis of two dimentions / critical thinking skills, and statistical and probabilistic knowledge. The results of the study indicated that pre-service middle school mathematics teachers reflected different critical thinking skills and made use of different statistical and probabilistic knowledge in different contexts. They mostly reflected interpretation skill on the basis of their statistical and probabilistic knowledge. Moreover, to what extent they made use of critical thinking skills was differentiated on the basis of their statistical and probabilistic knowledge. They reflected complicated critical thinking process dealing with conditional probability statements. They had difficulty with probabilistic statements underlying conditional probability especially in this process.

For this, we search the subjects of official documents and researches that addressed the teaching or the learning of probability, and we realize its growing withing mathematics education s field, confirming our hypotheses about the relevance of develop a research in this subject. In this context, we formulate our goal that s diagnose invariant operative mobilized by students. In situation of troubleshooting, and to seek elements that allowing a proposal for a concept of building model (learning evolution model). The work developed trying to relate the identified operative invariant with the elements of probabilistic literacy when learning of probability mobilizes elements of geometric probability, articulating the classical approach and the frequentist approach to probability. To achieve the goal, we formulated the following research question: Which literacy probabilistic elements identified in mobilizing operative invariants by third grade of high school students to solve problems that articulate the classical approach and the frequentist concepto f probability? Claving to answer this question, We Will use the theory of conceptual fields linking it with the principles of probabilistic literacy. As a research methodology chose the case study. Our sequence comprises three adapted teaching situations developed earlier research, in our research group, called A Bernoulli urn , B Pixels urn and C Franc-Carreau game and these situations were applied to a group of student volunteers attending the third high school of a private school in São Paulo. The analysis of the protocols built allowed us to identify students mobilized operative invariants allowing estimate the probability, articulating the classical approach and frequentist, confirming development of probabilistic assumptions literacy. Reported proportions via an own speech, transiting the concrete domains and pseudo-concrete. No student has achieved the full probabilistic literacy, that supposed to problem solving in the abstract domain, under the proposed scheme for a process of abstraction to be followed during learning / O tema no qual esta pesquisa se desenvolveu é o desenvolvimento do processo de aprendizagem da probabilidade. Para tal, buscamos primeiramente os conteúdos de documentos oficiais e pesquisas que abordaram o ensino ou a aprendizagem da probabilidade, e percebemos o seu crescimento dentro do campo da Educação Matemática, confirmando nossas hipóteses sobre a relevância de se desenvolver uma pesquisa nesse tema. Neste contexto, formulamos nosso objetivo que é diagnosticar invariantes operatórios mobilizados pelos alunos em situação de resolução de problemas, para que busquemos elementos que permitam uma proposta de modelo de construção de conceito (modelo de evolução de aprendizagem). O trabalho se desenvolveu buscando relacionar os invariantes operatórios identificados com os elementos do letramento probabilístico quando a aprendizagem da probabilidade mobiliza elementos da probabilidade geométrica, articulando o enfoque clássico e o enfoque frequentista da probabilidade. Para alcançarmos tal objetivo, formulamos a seguinte questão de pesquisa: Que elementos do letramento probabilístico identificamos na mobilização de invariantes operatórios por alunos do 3º ano do Ensino Médio ao resolver problemas que articulam o enfoque clássico e frequentista do conceito de probabilidade? Almejando responder a essa questão, utilizaremos a Teoria dos Campos Conceituais articulando-a com os princípios do letramento probabilístico. Como metodologia de pesquisa escolhemos o estudo de caso. Nossa sequência é composta por três situações didáticas adaptadas de pesquisa anterior desenvolvida em nosso grupo de pesquisa, denominadas A-Urna de Bernoulli , B-Urna de Pixels e C-O jogo Franc-Carreau e estas situações foram aplicadas a um grupo de alunos voluntários, cursando o terceiro ano do Ensino Médio de uma escola da rede privada da cidade de São Paulo. A análise dos protocolos construídos nos permitiu identificar que os alunos mobilizaram invariantes operatórios que permitiam estimar a probabilidade, articulando o enfoque clássico e frequentista, confirmando hipótese de desenvolvimento do letramento probabilístico. Descreveram proporções e por meio de um discurso próprio, transitando pelos domínios concreto e pseudoconcreto. Nenhum aluno atingiu o letramento probabilístico pleno, que supunha a resolução de problemas no domínio abstrato, segundo o esquema proposto para um processo de abstração a ser percorrido durante a aprendizagem
