1. O ensino da matemática na educacão de jovens e adultos: uma abordagem a partir de sequências didáticas
This study aimed to determine how sequences can contribute to the didactic teaching high school math in youth and adults at the Center for Advancing Education Equivalency (NAES) in Navegantes. From the theoretical and methodological proposed by Freire, Cury, Fonseca, and Méheut Zabala, the investigation the survey involved two classes of students, being dev

2. Planejamento instrucional adaptativo usando Workflow e planejamento genético
The course in distance learning can be customized taking in to account the specific characteristic of each student. This means that the learning environment has adaptativity. So, in order to develop adaptative systems of distance learning, it is necessary to consider the problems: instructional planning and the student model. The first problem allows to gene

3. Ambiente informatizado: para o aprofundamento da função quadrática por alunos da 2 série do ensino médio
The purpose of this study was to develop a computerized environment turned to teaching, in order to favor the deepening of the knowledge related to the polynomial function of second degree. In this environment, there is a sequence of activities that approaches the graphical representation of polynomial functions of second degree. It is based on the principle

4. Escolha e desempenho no trabalho de adultos com deficiência mental.
Choice making is a fundamental skill for all individuals. Choice opportunities are related with important questions of human development, and of paramount importance to the development of clinical and educational programs for mentally retarded individuals. Despite its practical importance, little is known about the effects that choice may have in the work en

5. MODELAGEM DE COMPOSIÇÃO DE OBJETOS DE APRENDIZAGEM / MODELING LEARNING OBJECTS COMPOSITION
The development of instructional content using new Information Technologies is an expensive, time-consuming and complex process that leads to the development of new methodologies. It was in this context that the concept of Learning Objects (LOs) was proposed as an approach that promotes content reuse. However, if content is expressed as small LOs, it is also

6. Modelo de ensino para mudanças cognitivas: um instrumento para o planejamento do ensino e a avaliação da aprendizagem em ciências
This study intends at discussing the theoretical basis of a constructivist model for the teaching of science and at the same time its empirical validation. The teaching model departs from the theory of causal knowledge building proposed by Piaget and Garcia (1984), according to which the focus of individuals theories shifts from intra- object attributes to i

7. Mechanisms of Mutagenesis by Chloroacetaldehyde
A number of bifunctional chemical mutagens induce exocyclic DNA lesions. For example, 2-chloroacetaldehyde (CAA), a metabolite of vinyl chloride, readily reacts with single-stranded DNA to predominantly form etheno lesions. Here, we report on in vivo mutagenesis caused by CAA treatment of DNA in vitro. These experiments used partially duplex phage M13AB28 re

8. Mechanisms of Mutagenesis by a Bulky DNA Lesion at the Guanine N7 Position
In order to examine the mechanisms of mutagenesis by a bulky DNA lesion at the guanine N7 position, the replicative form DNA of phage M13AB28 (mp8 without the amber codons in phage genes) was modified in vitro with aflatoxin B(1)-2,3-dichloride and transfected into appropriate Escherichia coli cells. Forward mutations in the lacZ α-complementing gene segmen
