O papel das interações professor-aluno na construção da solução lógico-aritmética otimizada de um jogo com regras

Na presente dissertação relato minhas inquietações profissionais intrinsecamente ligadas ao desconforto que eu percebia estar produzindo em meus alunos, a partir de uma prática docente, que, em muitos aspectos, necessitava de reformulações e adequações aos novos tempos. Era uma prática docente fundada nos pressupostos da ciência moderna, que pretendia descrever a realidade por leis deterministas, exatas, hierarquizadas e compartimentalizadas. Buscando transformar minha prática, (re)construí, na interação com meus pares, a proposta de um laboratório de Educação Matemática. As atividades desse laboratório deviam proporcionar uma fértil ambiência de interações verbais, despertando uma participação ativa dos alunos na construção de conhecimento. Com a certeza de que precisava ampliar a reflexão sobre meu trabalho docente, (re)construí uma nova visão pessoal de ciência, me apoiando nas idéias de alguns filósofos que se aproximam de um olhar transdisciplinar e do que tem sido chamado de ciência pós-moderna. Com esta nova concepção, procurei articular a Educação Matemática com os postulados da Psicologia Histórico-Cultural, a fim de me apropriar de ferramentas teórico-metodológicas para investigar minha prática docente. Na presente dissertação, relato uma análise microgenética de minha interação com dois alunos em uma atividade típica do laboratório de Educação Matemática: a aprendizagem da solução lógico-aritimética otimizada de um jogo com regras, o Nim. Filmei as 36 partidas que joguei com os alunos até que eles descobrissem a estratégia otimizada do jogo e depois as transcrevi, integralmente. A análise mostrou três momentos da construção da estratégia otimizada: a formulação e (re)formulação de hipóteses; a seleção, aplicação e teste de hipóteses e a transferência do raciocínio construído para a formulação de novas hipóteses. Observei transições genéticas em todos os momentos e mudanças nos padrões interativos que ora refletiam uma abordagem comunicativa predominantemente dialógica (no primeiro e terceiro momento), ora de autoridade (no segundo momento). Percebi como os alunos, interagindo comigo, desenvolveram a capacidade de regular suas próprias ações para resolver o problema que os desafiavam.

Education for Energy Efficiency through an Educational Game

This paper presents an assessment of an educational game for teaching the efficient use of electricity. Developed with Adobe Flash (R), it is a virtual board game where participants choose a car that starts the path and reaches the same final goal, going through a number of track steps defined in terms of a dice that each player rolls in turn. The car moves if the participant is able to correctly answer a question that is randomly generated by the software. The objective of the game is to answer questions related to energy efficiency promoting a healthy and attractive learning process for participants on concepts related to energy efficiency such as: the rational use of energy, the basic concepts of forms of energy generation, among others. The main objective of this paper is to assess the impact of the application of this virtual game in the teaching and learning process of high school students. Therefore, the game was applied in the discipline of physics in a class of junior high public school in the state of Sao Paulo. Initially, the class that had 43 students was divided into 10 groups of 4 students, and 1 group of 3 students. Each student group competed with one another. The idea was that each of them should indicate a student who was the representative of this group until only 4 group leaders were selected for the finals. At this stage, each student could interact with a group of up to ten students that acted as advisers. The adopted assessment process is based on the model proposed by Savi [7]. Then, at the end of the game, the students answered a prepared questionnaire based on the model proposed by Savi. According to Savi, although there are significant studies that show the importance of educational games for the process of cognitive development and learning concepts of students, there are few papers that present forms of assessing the potential of these resources. Thus, the assessment criteria proposed by Savi are based on the model of training evaluation by Kirkpatrick [3], taken as a reference to measure the efficiency of processes of continuing education courses for professionals. The authors assert that the metric of the evaluation proposed to assess the game is based on the first level of the model proposed by Kirkpatrick.

Programa de Atividade Física Adaptada com Uso de Vídeo Game: o que Pensam os Alunos?

Exergames are a new educational tool, and have been used by teachers in physical education classes because it is an activity that provides entertainment and caloric expenditure. The goal of this study was to verify the opinion of students in an elementary school class on a program of adapted physical activity using the videogame, developed during physical education classes. Study participants were students in a fourth-grade elementary school class that had a student with disability. The researcher and the Physical Education teacher elaborated the planning program of an adapted physical activity with the use of videogames. The classes were recorded in a log book and group interviews were conducted at the end of each class. The results showed that the classes were nice, fun and interesting experiences. The study concluded that the program was successful.

Aspectos formais da trilha musical de Yasunori Mitsuda para o game Chrono Cross e sua interação com o enredo

This work has the aim of evince compositional tools used in the development of musical scores for role-playing videogames through the analysis of Yasunori Mitsuda’s music for Chrono Cross (1999). This research is divided in two main parts: the first traces a historic path of the RPG genre on videogame consoles, since its birth as a tabletop game in the decade of 1970 until its consolidation on 3D game machines released in the 1990’s. The focus of this historical study concentrates on the aesthetics of this kind of game and on the multiple relations it settles with sound throughout the years. The second part is an analytical work on an assortment of pieces by Mitsuda for the aforementioned game, bringing up the most interesting aspects of the connections established between these compositions and the whole game.

The results obtained showed that students’ performance on tests improved after the use of simulators. It was found that the students had more homogeneous test results when using the simulator.

Televisão digital interativa na educação: desenvolvimento de um conteúdo. complementar ao ensino

This work had as objective the development of a prototype of educational content, as an experimental process, making use of resources from Interactive Digital TV. The characteristics of interactive digital terrestrial television are presented, in the form of a media mode capable of performing as a complementary source to education. The methodology used is composed of four phases: deduction, analysis, induction and synthesis. Its conception takes as issue the expressed need stated by UNESCO to use ICT (Information and Communications Technology) towards education, as well as the possibility of applying digital television in an educational process. The content is structured in the form of a quiz, a type of question-answer game as an informal way of education for high school students. The prototype developed in this work is presented as a structural script and map, taking into account the necessary activities and routines to put it into operation in the tested environments, eclipse, virtual set-top-box and Developer Box. The practice of prototyping was carried out in NCLua, based on middleware Ginga. As a result, we concluded that Ginga offers enough support to carry out the task, providing characteristics of interaction to publish the proposed content, at the moment of the actual practice.

NASH game and mixed H2/H∞ control

In this work a Nonzero-Sum NASH game related to the H2 and H∞ control problems is formulated in the context of convex optimization theory. The variables of the game are limiting bounds for the H2 and H∞ norms, and the final controller is obtained as an equilibrium solution, which minimizes the `sensitivity of each norm' with respect to the other. The state feedback problem is considered and illustrated by numerical examples.
