▼ This study investigated the comparison between captured and revealed Pedagogical Content Knowledge (PCK) about graphs of motion. The aim of the study was to explore PCK when captured in a written format and discussions (captured PCK) and compare it to the PCK that the same teachers revealed in practice (revealed PCK) when teaching the topic. Four Grade 10 Physical sciences teachers were purposively and conveniently selected as participants of the study. Their PCK was captured through Content Representations (CoRes) and interviews. The revealed PCK on the other hand was gathered through lesson observations. The Topic Specific Pedagogical Content Knowledge (TSPCK) model was used as the framework that guided the analysis of the two manifestations of PCK. The focus was on teachers’ competences in the TSPCK components namely; learners’ prior knowledge including misconceptions, curricular saliency, what is difficult to teach, representations including analogies, and conceptual teaching strategies. The results of this study indicated that teachers’ competences in the TSPCK components varied. This was evident in both the captured and the revealed PCK. Thus it suggested that a teacher’s level of competence in one component is not necessarily an indication of his or her competence in the other components that define PCK, and subsequently in his/her overall captured or revealed PCK. Furthermore, the study suggested that the level of competence in a component in the captured PCK is not necessarily an indication of the level of competence within that component that the teacher would reveal during lesson presentation. The level may be the same, slightly different (higher or lower) or even be drastically different in the lesson than suggested by the captured PCK. A concluding remark was then made that teachers’ captured PCK is not necessarily a true reflection of the PCK they reveal during lesson presentation and that different instruments must be used to reflect on and assess teachers’ PCK in a topic.

Este trabalho é uma pesquisa qualitativa que tem como finalidade investigar o desempenho de alunos do 2 ano do Ensino Médio de uma escola pública estadual de São Paulo, sobre a interpretação e análise de informações contidas em gráficos. O estudo foi inspirado no projeto de recuperação e reforço de alunos da rede pública estadual, São Paulo Faz Escola, proposto pela Secretaria de Educação do Estado de São Paulo no ano de 2008. Especificamente, nos detivemos no material direcionado aos alunos de 7 e 8 séries, na forma de um jornal, no qual o bloco de Ciências Naturais sugere diversas atividades, envolvendo textos e gráficos que tratam do crescimento de determinadas populações de quatis. O ponto de partida dessa proposta foi discussão do significado da cadeia alimentar relacionada à vida animal de uma determinada região, culminando com o cálculo das taxas de crescimento bruto e relativo. Percebemos que essas atividades com representações gráficas, solicitavam dos alunos habilidades matemáticas e capacidade de leitura e interpretação de dados contidos em gráficos, para resolvê-las. Identificamos aí uma boa oportunidade para realizar nosso trabalho, visando investigar como os alunos se comportam quando solicitados a buscar informações contidas em gráficos, para fazerem comparações de quantidades e manipularem conhecimentos mobilizáveis de matemática, no que se refere às operações de subtração e divisão. O instrumento para coleta de dados foi constituído por cinco atividades contento textos e representações gráficas, que foram norteadas pela teoria dos Registros de Representações Semióticas de Duval, e pelos níveis de compreensão de representações gráficas, de Cúrcio. Os estudantes realizaram as atividades num clima de entusiasmo e seriedade e os resultados permitem inferir que, com as habilidades trabalhadas, os alunos parecem estar instrumentalizados a iniciar a análise do comportamento de funções a partir de seu registro gráfico. Esta conjectura pode servir de ponto de partida para futuras pesquisas

This work is a qualitative research that it has as purpose to investigate the students of the 2nd year of the Medium Teaching of a state public school of São Paulo acting, on the interpretation and analysis of information contained in graphs. The study was inspired in the recovery Project and students of the state public net reinforcement, "São Paulo Faz Escola", proposed by the General Office of Education of the State of São Paulo in the year of 2008. Specifically, we stopped in the material addressed to the students of 7th and 8th series, in the form of a newspaper, in which the block of Natural science suggests several activities, involving texts and graphs that treat of the growth certain quatis populations. The starting point of that proposal was discussion of the meaning of the alimentary chain related to the animal life of a certain area, culminating with the calculation of the taxes of rude and relative growth. We noticed that those activities with graphic representations, requested of the students mathematical…

▼ Internet technology, in modern communities, has become an indispensable tool for everyday life since most people use it on a regular basis and do many daily activities online. This frequent use of the internet means that measures taken for internet security are indispensable since the web is not risk-free. One of those risks is the fact that the web is an environment where intellectual property is under threat since a huge amount of digital data are transferred every day, and thus such data may end up on a user who falsely claims ownership.Digital watermarking (or, simply, watermarking) is a technique for protecting the intellectual property of a digital object; the idea is simple: a unique identifier, which is called watermark, is embedded into a digital object which may be used to verify its authenticity or the identity of its owners. A digital object may be audio, picture, video, text, or software, and the watermark is embedded into object's data through the introduction of errors not detectable by human perception; note that, if the object is copied then the watermark also is carried in the copy. Efficient watermarking techniques should be able to embed and successfully extract the watermark, even after the digital object has been attacked, i.e., it has been subjected to transformations by malicious users that aim to mislead the watermark extractor.The issues addressed in this thesis concern the design of efficient and easily implementable codec systems for watermarking software and digital media, such as image, audio, and text. Previous works on digital watermarking propose specific encoding techniques for a specific type O of a digital object, i.e., the main idea of a proposed technique for watermarking a digital object of type O cannot be efficiently applied to a different digital object of type O'; for example, the main idea of a proposed technique for watermarking a software (application program) P, cannot be efficiently applied to image I, audio (signal) S or even text T. In our work, we overcome such a drawback by proposing algorithmic techniques for encoding a watermark w into a self-inverting permutation (or, SiP for short) π*, and then embedding the self-inverting permutation π* into different digital objects, i.e., software, image, audio, and text, by using different representations of the same SiP π*. The data structures used to represent the SiP, as well as the encoding techniques, encompasses important properties allowing us to design a codec system which efficiently detect attacks.In the first part of the thesis, presents the basic research on encoding watermark members as graph structures through the use of self-inverting permutations (SiP) and algorithms for multiple encodings. We introduce the notion of a bitonic permutation, and present our algorithm Encode_W.to.SiP for encoding an integer w as a self-inverting permutation π*, along with the corresponding decoding algorithm Decode_SiP.to.W, and discuss important properties of the self-inverting permutation π*. Then, we define the main…
