A aprendizagem é um processo continuo permeado por construções e reconstruções do conhecimento, com a inserção do computador no processo de ensino aprendizagem, juntamente com a análise das abordagens da Psicologia Educacional e Educação Matemática, foi possível, neste trabalho, a elaboração de um prototipo computacional voltado para o auxilio a aprendizagem da matemática. Este prototipo e um ambiente computacional interativo para auxiliar o aprendizado das quatro operações básicas (adição, subtração,multiplicação e divisão). Assunto este de grande repercussão no ambiente escolar, pois se não aprendido adequadamente, apresenta sérios problemas na evolução do aprendizado matemático do estudante. O trabalho envolve quatro etapas: Aspectos teóricos sobre o processo de ensino aprendizagem, dando-se maior ênfase a abordagem construtivista; Processo de ensino aprendizagem de Matemática, suas dificuldades e perspectivas de mudanças mediante ao aprendizado auxiliado por meios computacionais; concepção e modelagem do prototipo seguido dos Resultados obtidos durante aplicações do mesmo, resultados esses favoráveis a proposta inicial do trabalho.

Este trabalho objetiva analisar os possíveis efeitos que o uso da Modelagem Matemática, enquanto estratégia de ensino, provoca no processo de aprendizagem dos alunos da disciplina Cálculo III – EDO (Equações Diferenciais Ordinárias). A pesquisa foi desenvolvida em uma turma de alunos do 2° ano do curso de Engenharia da Computação, na Universidade Federal do Pará. O trabalho é de cunho qualitativo onde foram levados em consideração os aspectos sociais que permeiam uma sala de aula universitária. Importante destacar que houve a participação direta da professora-pesquisadora de Matemática. Para que eu pudesse fazer a coleta dos dados, utilizei alguns instrumentos que considerei essenciais, tais como: observações, gravações em áudio, questionários semiestruturados e registros escritos dos alunos. De posse de alguns resultados preliminares, me foi possível observar o quanto a Modelagem Matemática desempenha um papel relevante na aprendizagem dos conteúdos matemáticos por parte dos alunos, pois foi possível eles interagirem com outras áreas do conhecimento sendo, desta forma, estimulados a realizarem pesquisa e, simultaneamente, serem parte do processo de ensino e aprendizagem que foi gerado no ambiente de sala de aula. Observei, também, que a utilização da Modelagem Matemática, enquanto estratégia de ensino e aprendizagem, conduziu os alunos a despertarem para os aspectos reflexivos e críticos até então adormecidos, uma vez que são necessários para uma aprendizagem com qualidade para, assim, construírem seus conhecimentos acadêmicos e profissionais.

The purpose of this study was to determine a shape factor to estimate area of leaflets of two peanut cultivars (IAC TATU ST, IAC RUNNER 886). Correlation studies were conducted involving real leaf area (Sf) and leaf length (C), maximum leaf width (L) and the product between C and L. For each cultivar was determined a form factor (f) by means of regression analysis between the product of the length by the width and the actual area of leaves and the correlation between leaf area estimated by the correction factor and direct measurement. All evaluated models (linear, exponential or geometric) provided good estimates of leaf area (above 87%). Linear models had the best fit, passing or not through the origin. From a practical viewpoint, it is suggested to use the linear model involving the C and L product, using a linear coefficient equal to zero, with values of factor f equal to 0.7111 and 0.7266 for IAC RUNNER 886 and IAC TATU ST, respectively. The method of dimensions is feasible for the estimation of leaf area for both peanut cultivars, for showing good r(2) values (0.97), with errors below 3%, even when used with independent data.

Years after the constructivism theory was adopted by “Parameters for National Syllabuses”, the results have pointed to a worse performance in teaching and learning with regards to reading and writing. This article presents the conclusions proceeding from investigation about the probable reasons for the student’s lack of success in reading and writing, and its relation to Emília Ferreiro’s constructivism proposals. Interviews were made as well as sit in class observation were done, with twenty teachers at six Fundamental Level 1 schools in Ourinhos, SP State, in schools that had been awarded the best and the worst performance rating in the Prova Brasil-2005, with this objective: to know and analyze the teacher’s conceptions under their practices and their practices in the classes. The conclusion is: it is not possible to attribute the students’ lack of success in reading and writing; these studies showed that many teachers, most of them, have a non-constructivist concept of teaching and learning, it means that they do not apply Ferreiro’s researches.

In this research, we analyzed the use of manipulative materials and games as motivators tools that facilitate the comprehension of fractions content when presented to a class of students from the 9th grade from a public school in Guaratinguetá-SP city. The students are 14 and 17 years old. Initially we presented the benefits that could bring manipulative materials for teaching and learning with understanding, followed by historical accounts of the Tangram material. We show the advantages of the games, when properly used in activities classroom. The game titled Dominoes fractions using the Tangram was applied in order to check if students retook properly the fractions contents. This research was motivated students to participate in math classes and this motivation may have promoted the understanding of the contents worked

Over the last years, the new technologies have changed the way we relate to information and communicate with other people, which has brought on impact to foreign language teaching and learning, and, consequently, to the area of foreign language teacher education. The abbreviation CALL (Computer Assisted Language Learning) has been used to designate the processes of language teaching and learning with the use of computers, and language teacher education in CALL to name teacher education for and with the use of new technologies, since a number of authors point to the interdependence of both processes. We intend in this article to present an overview of the literature of the area of language teacher education in CALL nowadays and discuss issues related to the use of new technologies concerning its integration to teacher education and the functional and institutional roles to be taken. We also present two proposals of teacher education with the use of new technologies which are being implemented and at the same time studied in Brazil, which we believe have essential elements for the development of language teachers for and with the use of new technologies currently.

The aim of this study was to evaluate if upward or downward head inclination might interfere with determination of the growth stage, using cervical vertebrae maturation index (CVMI), in order to verify the accuracy of such diagnosis when radiographs are taken with errors. Forty-nine patients, 26 females and 23 males, aged 9 to 15 years, were submitted to 3 lateral cephalograms: normal (NHP), with 15° upward head inclination (NHP-Up), and with 15° downward head inclination (NHP-Down). Three examiners evaluated the CVMI on the 147 cephalograms. The agreement among examiners was higher in the evaluation of cephalograms taken in NHP. The weighted Kappa test revealed moderate to substantial agreement between NHP and NHP-Up and between NHP and NHP-Down. There was greater agreement between NHP-Up and NHP-Down. It may be concluded that the evaluation of the CVMI on cephalograms in NHP is different as compared with radiographs taken with inclinations. Both NHP-Up and NHP-Down exhibited greater disagreement in the interpretation among examiners, since the evaluation method was not designed for cephalograms with positioning errors.
