Ciências no ensino infantil: contribuições da introdução de atividade lúdicas e investigativas para o processo de ensino e aprendizagem

Here we present the introduction of a range of science´s experimental activities, designed and developed with a focus on the investigative methodology in an interdisciplinary context. The activities have as main theme water and covers topics of heat and temperature, density and states of matter. The relevance of this project is to promote the first contacts of children with Science in an attractive way, and correctly of the scientific point of view, respecting the cognitive level of each child, trying to stimulate the development of hypotheses, creativity and critical thinking, as well as the development of the narrative, descriptive language and drawing. We developed seven lesson plans that were applied in the year of 2012, during three weeks in a school for early childhood education in the city of Bauru. The activities were conducted with fifteen children aged four to six years old together with the teacher responsible for the group. As main contributions in the teaching learning process we cite: acquiring of new vocabulary, progress in the development of hypotheses, development of collective work, evolution of knowledge of the topics covered, and use of the acquired knowledge to new problems and situations

Sistema de recomendação de produtos online baseado em palavras-chave

This project aims to explore the many methods used for the development of recommendation systems to user ’ s items and apply the content - based recommendation method on a prototype system whose purpose is to recommend books to users. This paper exposes the most popular methods for creating systems capable of providing items (products) according to user preferences, such as collaborat ive filtering and content - based. It also point different techniques that can be applied to calculate the similarity between two entities, for items or users, as the Pearson ’s method, calculating the cosine of vectors and more recently, a proposal to use a Bayesian system under a Dirichlet distribution. In addition, this work has the purpose to go through various points on the design of an online application, or a website, dealing not only oriented algorithms issues, but also the definition of development to ols and techniques to improve the user’s experience. The tools used for the development of the page are listed, and a topic about web design is also discussed in order to emphasize the importance of the layout of the application. At the end, some examples of recommender systems are presented for curiosity , learning and research purposes

Uma proposta para utilização do computador no processo de ensino e aprendizagem dos primeiros números do sistema hindu-arábico

The aim of this work is presenting the development and the results of a research, which focus of interest has been the making of softwares that could help the process of teaching and learning of the hindu-arabic numerals system, on children in the alphabetical stage. Since the most important presupposes to this work are the development of the number concept according to Jean Piaget (1986-1980) and the reality of the classroom, then three different moments have been fixed: the creation of a beginning scheme of computer activities; the aplication of these activities on children in the alphabetical stage; and, finally, an analysis of the limits and possibilities of these activities while an environment cause of actions that would benefit the process of teaching and learning of the mentioned content. Finally, based on the anlysis of the results obtained, the next step was fixing a more consistant set of computer activities, which makes up a proposal to the use of computer in the process of teaching and learning of the first hindu-arabic numbers

Os limites e as possibilidades de uma sequência didática: o conceito de proporcionalidade e a aprendizagem de alunos do 5º ano do Ensino Fundamental

This study aimed to analyze the limits and possibilities of a didactic sequence, addressing the concept of proportionality in the learning of students in 5th year of elementary school. From the results of the Diagnostic Assessment Initial applied to students in a class of 5th grade of elementary school, we selected eight (8) students who participated in the constituent activities of that instructional sequence. For the development of this sequence were used theoretical elements of Genetic Epistemology (Piaget, 1990), the theory of fields of Conceptual Vergnaud (1996) and the definition of instructional sequence proposed by Zabala (1998). Finally, after 20 days of application of these activities, we applied the Diagnostic Assessment Final aimed at investigating which concepts related to proportionality were built by the participating students. By analyzing the collected data, it can be concluded the following about the possibilities of teaching sequence: 1) students who, in Diagnostica Home Assessment used the multiplication algorithm, but also did not indicate the comparison between quantities are now performing; 2) students who, in the Diagnostic Assessment Initial, used the addition algorithm, now gradually are using the multiplication algorithm; 3)students who, in the Diagnostic Assessment Initial, could not solve problems involving the idea of proportionality, are now resolving, however, still use, in large part, the addition operation as a strategy for this proportional thinking. Now, in relation to the limits of the sequence noted: 1)time sufficient to propose a higher number of problem conditions to be carried by students who may have been a trigger of construction have not through the proportional multiplication;2)the distant proposition situations of assimilation schemes (interpretation) of the students, which may have caused certain imbalance in them, preventing them from thinking about the problem situation;3)the rapid passage of...

Simetria no ensino fundamental através da resolução de problemas: possibilidades para um trabalho em sala de aula

This paper presents an alternative way of working with the theme of symmetry in the elementary school classroom. The proposal is based on qualitative research developed in the Professional Masters degree program in Science and Mathematics Teaching. We conducted field-work consisting of applying a sequence of activities for students in the seventh grade. The sequence was developed from the perspective of mathematics teaching using problem solving, taking into consideration aspects relevant to the study of geometry, such as intuition and visualization. In carrying out the activities, the dialogues between students and teacher were recorded and later transcribed. For data analysis we used the procedures of phenomenology. When interpreting the data, we observed that the teaching of symmetry using problem-solving enhances learning. We also found that, in an investigative environment, students are able to identify properties, argue about the geometric characteristics, and justify their opinions.

Considerações teóricas sobre o uso da informática na resolução de problemas de trigonometria

The present work is determined to analyse trigonometry problem solving with the help of CabriGéomètre II software from the perspective of two axes of mathematics teaching which are: the concept formation in Klausmeier and Goodwin´s perspective(1977) and problem solving according to Sternberg’s conception(2000). With such an approach traces of a more significant learning may be found , which according to Ausubel(1980) enables the adoption of better teaching and learning practices.
