Hypergoemetric Series are very important in mathematics and come up regularly when dealing with the precise definitions of constants such as <i>e</i>, &pi; and Apery's constant &sigmaf;(3). The evaluation of such series to high precision is traditionally done with multiple divisions, multiplications and factorials, which all takes a long time to compute, especially when the computation is done on a single machine. The interest lies in performing this computation in parallel and in a distributed fashion. In this thesis, we present a simple distributed toolkit for doing such computations by splitting the problem into smaller sub-problems, solving these sub-problems in parallel on distributed machines and then combining the result at the end. Our toolkit takes care of all the networking for the user; connectivity, dropped connections, management of the Clients and the Server. All the user has to provide is the definition of the problem; how to split the problem into sub-problems, how to solve the sub-problems and finally how to combine the sub-problems and produce a result. The toolkit records timings for computation as well as for communication. What is different about our application is that all the code is written in Java (which is completely machine independent) and all the Clients are Java Applets. This means that having a web browser in enough to take part in the computation when it is distributed over the internet. We are almost guaranteed that every computer on the internet has a web browser. The Java Plug-in (if unavailable) can easily be downloaded from Sun's web site. We present a comparison between Java's native BigInteger library and an FFT based Integer Library written by R. Howell of University of Kansas. This study is important since we are doing computations with very large integers. To test our system, we evaluate <i>e</i> to different number of digits of precision and show that our system truly works and is easy for anyone to use.

Diploma thesis "Using the Internet to teach physics at school" discusses the possibility of using the Internet as tools for teaching physics at elementary school. Its use in teaching would also improve the computer literacy of teachers and pupils. It would meet the key competencies for learning, problem solving, communication, social and personal, civic and labor. The practical part of the thesis contains the knowledge of teaching physics in the 8th classroom of elementary school, where the results are then compared using the Internet in teaching and learning without the use of the Internet. There are also links and reviews of sorted physical websites and thein use in teaching. The last part of work is a questionnaire for teachers of physics at the elementary school and its evaluation.

It is available in Moodle of the Mathematics Department of UFSCar, was created in four topics, one for each learning situation provided in the student diary volume 3 of the third grade of High School of the Secretaria of Education of the State of São Paulo .Each topic consists of activities like lessons, quizzes, sending files and participation in specific forums. The lessons seek to lead the student to acquire the skills provided in the Student notebook. The questionnaires are used to strengthen and verify that learning. The purpose of sending files and participating in the forums is to provide a self-evaluation and development of students' writing skills The environment does not change the principles guiding the curriculum of the State of São Paulo, keeping the content and context of encouraging the development of personal skills, especially those related to reading and writing mathematics. It is expected that the application of the environment, the use of the viewers, the participation in the forums and execution of activities and exercises with the aid of technology, encourage, motivate and facilitate the teaching and learning of mathematics, leading each participant to resize their concepts and knowledge. The participation of undergraduated students in the activities of virtual learning environment seeks to provide grants to train a teacher who can act as mediator, facilitator and challenger of learning, ready to work with students to construct their knowledge through manipulation, exploitation, navigation and communication with the "objects" presented. / O presente trabalho relata a elaboração de um ambiente virtual de aprendizagem (AVA) para o ensino de Funções, com a utilização de visualizadores criados no GeoGebra, se constituindo em um dos produtos do Mestrado Profissional desenvolvido na Universidade Federal de São Carlos. Disponibilizado no Moodle do Departamento de Matemática da UFSCar, o AVA foi idealizado em 4 tópicos, um para cada situação de aprendizagem prevista no caderno do aluno volume 3 da 3a série do Ensino Médio, da Secretaria de Estado da Educação do Estado de São Paulo. Cada tópico é formado por atividades do tipo lições, questionários, envio de arquivos e a participação em fóruns específicos. As lições procuram levar o aluno a adquirir as habilidades previstas no Caderno do Aluno. Os questionários servem para reforço e verificação dessa aprendizagem. Já o envio de arquivos e a participação nos fóruns propiciam a auto-avaliação dos estudantes e o desenvolvimento das habilidades de escrita. O ambiente não altera os princípios norteadores do currículo do Estado de São Paulo, mantendo a contextualização dos conteúdos e favorecendo o desenvolvimento de competências pessoais, especialmente as relacionadas à leitura e a escrita matemática. Esperase que a aplicação do ambiente, a utilização dos visualizadores, a participação nos fóruns e a execução de atividades e exercícios com o auxílio da tecnologia incentive, motive e facilite o ensino e a aprendizagem da Matemática, levando cada participante a redimensionar seus conceitos e conhecimentos. A participação de alunos de Licenciatura nas atividades do AVA busca fornecer subsídios para formar um professor que possa atuar como mediador, facilitador e desafiador da aprendizagem, preparado para trabalhar com alunos que constroem o conhecimento por meio da manipulação, exploração, navegação e comunicação com os objetos apresentados.

With the prevalence of internet, it is gradually becoming a trend to use the network as a tool of computer-added education. However, it is used to present the computer-added education with static state of the word, but it is just convenient to read for the user and there are no difference with traditional textbook. As the growing up of WWW and the development of Java, the interactive computer-added education is becoming a trend in the future and it can promote the effect of teaching basic statistics with the application of this new media. The instructor can take advantage of HTML by combining with Java Applets to achieve the display of interactive education through WWW. In this paper, we will use six examples of Java Applets about statistical computer-added education to help student easily to learn and to understand some abstract statistical concepts. The key methods to reach the goal are visualization and simulation with the display of graphics or games. Finally, we will discuss how to use the Applets and how to add the Java Applets into your homepage easily.
