Um estudo sobre a aprendizagem de alguns conceitos algébricos e geométricos

The objective of the present work was develop a study about the writing and the algebraic manipulation of symbolical expressions for perimeter and area of some convex polygons, approaching the properties of the operations and equality, extending to the obtaining of the formulas of length and area of the circle, this one starting on the formula of the perimeter and area of the regular hexagon. To do so, a module with teaching activities was elaborated based on constructive teaching. The study consisted of a methodological intervention, done by the researcher, and had as subjects students of the 8th grade of the State School Desembargador Floriano Cavalcanti, located on the city of Natal, Rio Grande do Norte. The methodological intervention was done in three stages: applying of a initial diagnostic evaluation, developing of the teaching module, and applying of the final evaluation based on the Mathematics teaching using Constructivist references. The data collected in the evaluations was presented as descriptive statistics. The results of the final diagnostic evaluation were analyzed in the qualitative point of view, using the criteria established by Richard Skemp s second theory about the comprehension of mathematical concepts. The general results about the data from the evaluations and the applying of the teaching module showed a qualitative difference in the learning of the students who participated of the intervention

Gestão ambiental na indústria do petróleo :um estudo sobre as práticas de gestão na perspectiva da aprendizagem organizacional

This work discusses the environmental management thematic, on the basis of ISO 14001 standard and learning organization. This study is carried through an exploratory survey in a company of fuel transport, located in Natal/RN. The objective of this research was to investigate the practices of environmental management, carried through in the context of an implemented ISO 14001 environmental management system, in the researched organization, from the perspective of the learning organization. The methodology used in this work is supported in the quantitative method, combining the exploratory and descriptive types, and uses the technique of questionnaires, having as scope of the research, the managers, employee controlling, coordinators, supervisors and - proper and contracted - of the company. To carry through the analysis of the data of this research, it was used software Excel and Statistical version 6.0. The analysis of the data is divided in two parts: descriptive analysis and analysis of groupings (clusters). The results point, on the basis of the studied theory, as well as in the results of the research, that the implemented ISO 14001 environmental system in the searched organization presents elements that promote learning organization. From the results, it can be concluded that the company uses external information in the decision taking on environmental problems; that the employees are mobilized to generate ideas and to collect n environmental information and that the company has carried through partnerships in the activities of the environmental area with other companies. All these item cited can contribute for the generation of knowledge of the organization. It can also be concluded that the company has evaluated environmental errors occurrences in the past, as well as carried through environmental benchmarking. These practical can be considered as good ways of the company to acquire knowledge. The results also show that the employees have not found difficulties in the accomplishment of the tasks when the manager of its sector is not present. This result can demonstrate that the company has a good diffusion of knowledge

Um estudo sobre o ensino-aprendizagem das demonstrações matemáticas

Demonstrations are fundamental instruments for Mathematics and, as such, are frequently used by mathematicians, math teachers and students. In fact, demonstrations are part of every Mathematics teaching environment, because Mathematics considers something true when it can be demonstrated. This is in contrast to other fields of knowledge that employ observation and experimentation to validate truth. This dissertation presents a study of the teaching and learning of demonstrations in Mathematics, describing a Teaching Module applied in a course on the Theory of Numbers offered by the Mathematics Department of the Universidade Federal do Rio Grande do Norte for mathematics majors. The objective of the dissertation was to propose and test a Teaching Module that can serve as a model for teaching demonstrations. The Teaching Module consisted of the following five steps: the application of a survey to determine the students‟ profiles and their previous knowledge of mathematical language and techniques of demonstration; the analysis of a series of dialogues containing arguments in everyday language; the investigation and analysis of the structure of some important techniques of demonstration; a written assessment; and, finally, an interview to further verify the principal results of the Teaching Module. The analysis of the data obtained though the classroom activities, written assessments and interviews led to the conclusion that there was a significant amount of assimilation of the issue at the level of relational understanding, (SKEMP, 1980). These instruments verified that the students attained considerable improvement in their use of mathematical language and of the techniques of demonstration presented. Thus, the evidence supports the conclusion that the proposed Teaching Module is an effective means for the teaching/learning of mathematical demonstration and, as such, provides a methodological guide which may lay the foundations for a new approach to this important subject

Uma proposta de ensino e aprendizagem de Língua Inglesa integrada ao uso das TICS para o desenvolvimento da autonomia dos aprendizes

This study focuses on the teaching and learning of English based on a new theoretical perspective concerning the Zone of Proximal Development (ZPD), which points to the apprehension of metacognitive processes as the way to reach learning autonomy. The theoretical set underline this study is those of a new pedagogy based on the symbiosis of Bruner‟s (2002) and Freire‟s (2009) concepts and in the metacognitive theory. In a social context dominated by the Communication and Information Technologies (CIT), the integration between teacher and learners with the support of the internet has been used as the way to operationalize this new emergent proposal of the theoretical perspectives. The analyses have been conducted through Systemic and Integral Action Research. The results at the end of this study corroborate our hypothesis that the enlargement of spontaneous knowledge of the learners can facilitate the understanding of scientific concepts, stimulating their metacognition and thus promoting their autonomy.

Design participativo de um ambiente virtual de aprendizagem de histologia

A progressiva diminuição de carga horária destinada às disciplinas baseadas em microscopia, os altos custos dos laboratórios e a necessidade de materiais multimídia que integrem a teoria com a prática e incentivem os alunos a estudar têm propiciado o desenvolvimento de atlas interativos e ambientes virtuais de aprendizagem, que são, em geral, pouco adotados por professores e alunos. O presente trabalho descreve o desenvolvimento de um ambiente virtual de aprendizagem de Histologia, baseado na metodologia de design participativo e em princípios da ergopedagogia, no qual alunos e professores conduziram sua construção. Com base na avaliação do protótipo, concluiu-se que, embora os ambientes virtuais devam adequar-se às necessidades de aprendizagem, características dos alunos e ao contexto de uso, é preciso que os professores integrem estes recursos em suas práticas de ensino, para seu uso efetivo

The proposal focuses on some properties, special cases and applications of affine functions in order to show the importance of the demonstrations while awaken student interest by showing how this function is important to solve everyday problems

Corpo, movimento e aprendizagem na psicocinética de Jean Le Boulch

School teachers in the discipline of Physical Education, we find ourselves constantly in question of methodological and epistemological issues of practice. This research aims to identify human body understanding, movement and theoretical learning proposed by examining the work of Jean Le Boulch and his approach to Physical Education. We seek to indicate epistemological elements about Physical Education theory and practice, believing that this approach and dialog comes to contribute with this field of knowledge. Boulch, a French teacher of Physical Education, Medicine and Psychology, had an important influence in Brazilian Physical Education during the 1970s and 1980s. His main contribution was teaching courses and knowledge about psychomotricity. Boulch’s studies helped to build knowledge of human movement; considering his importance in people’s development and a critic to a mechanistic view of body and movement. Our reflections will be based on the concepts brought from psychokinetics presented in the bibliographic references of Le Boulch in Brazil, and other references developed by him in this country including conferences, lectures and interviews. This reflection includes the debaters of his work. We chose a theoretical approach referring to the Phenomenology of philosopher Maurice Merleau-Ponty (1999) as a methodological reference considering the influence of his thought in Le Boulch studies. This thesis examines the learning and practice of teaching the Physical Education field of knowledge. We conclude that the body being an entity that exists for itself in the world and that contact with the world starts from human movement. Ultimately, new trains of thought for the teaching of physical education can be set from the reflection of phenomenological concepts brought by Le Boulch in his theory.

A motivação no teatro musical sob a perspectiva da teoria da autodeterminação

Este estudo teve por objetivo geral investigar os processos motivacionais dos participantes de um grupo de Teatro Musical sob a perspectiva da Teoria da Autodeterminação - TAD (RYAN; DECI, 2004; REEVE, 2006). Os pesquisadores Edward Deci e Richard Ryan (1985, 2000, 2008a, 2008b) afirmam que todos os indivíduos possuem uma propensão inclinada à autorregulação. Por esse motivo, a TAD analisa as razões pelas quais os indivíduos podem se envolver ou evitar participar de determinadas atividades, e adota um conceito de internalização que é representada por um continuum de autodeterminação, evidenciando os diferentes tipos de motivação previstos na miniteoria da integração organísmica. Os tipos de motivação podem ser identificados de acordo com o nível de autodeterminação dos indivíduos, através da satisfação de três necessidades psicológicas básicas: a necessidade de autonomia, a necessidade de competência e a necessidade de pertencimento. Esta pesquisa tem uma abordagem qualitativa e escolheu-se o estudo de entrevistas como estratégia de investigação, utilizando a entrevista semiestruturada como principal técnica de coleta de dados. A pesquisa foi realizada com 12 participantes de um grupo de Teatro Musical de uma universidade do Estado Rio Grande do Norte, referida na pesquisa com o pseudônimo de Companhia Musicale. Os resultados apontam que a principal motivação dos alunos não era a intrínseca. Portanto, a motivação foi considerada complexa e multifacetada, pois os participantes passaram por internalização do comportamento dependendo das condições situacionais. As complexidades nas interações puderam promover a satisfação das necessidades psicológicas básicas dos integrantes que apresentaram maior internalização dos comportamentos autodeterminados. Assim, os integrantes com maior desempenho nas tarefas foram os que internalizaram a importância e o valor das atividades. O estudo busca contribuir para futuras pesquisas e colaborar no sentido de perceber a importância de investigar e promover a motivação de alunos, professores, diretores, regentes, coordenadores e participantes de grupos artísticos em geral, trazendo esclarecimentos que ressaltam as contribuições e a importância que a motivação tem sobre o ensino, a aprendizagem musical e o envolvimento de participantes de grupos artísticos em diferentes atividades.

Integração e interdisciplinaridade no processo ensino/aprendizagem de projeto: o curso de Arquitetura e Urbanismo da Universidade Potiguar de Mossoró-RN

Training in Architecture and Urbanism with its general characteristic involves, in its nature, knowledge of various areas (technology, theory, history, representation, and design), being the space of design conception that place where the synthesis of this knowledge is reflected more clearly. We believe that the integrated work in the architectural curriculum can provide an overview of the project, thus contributing to better training of the architect. This research aims to reflect on the role of integration and interdisciplinary in teaching architectural design. This theme has been work recurrently by critics in the teaching area of project and events of the area as the seminars of the Projetar, highlighted by several authors to search integration as an essential pedagogical approach to design education. The work aims to contribute to reflection and awareness of those involved on the importance of integration in the architectural course of project processes. For this, we analyzed the potential and limits of this process in Architecture and Urbanism Course (CAU) at the Universidade Potiguar (UNP) Mossoró, which has the integration and interdisciplinary recorded since the Pedagogical Project of the Course. This analysis will be performed by observing the development of “interdisciplinary work” in the fifth term during the first half of 2014.1. This research concerns an exploratory qualitative study that aims to investigate specific issues on the teaching/learning architecture project and the integration in architecture courses, following a non-participant observation in architectural design classes in the fifth term of CAU/UnP/ Mossoró, and analysis of final products, which would be the work of the last unit of the semester, called “Interdisciplinary work”. Questionnaires for the teachers who participated in the process has been apply via email and analyzed. Reflection supports several other already carried out to identify the difficulties inherent in applying these principles satisfactorily. Noting, however, that interdisciplinarity, in fact, it goes beyond integration and is even more difficult to achieve. In addition to an educational project that incorporates these principles, such as the course of Architecture and Urbanism of the UNP-Mossoró, full adhesion it is necessary by the faculty and students of this teaching philosophy.

Aceitação e uso de ambiente virtual de aprendizagem no contexto de um curso de capacitação para servidores públicos

This study aimed to examine how students perceives the factors that may influence them to attend a training course offered in the distance virtual learning environment (VLE) of the National School of Public Administration (ENAP). Thus, as theoretical basis it was used the Unified Theory of Acceptance and Use of Technology (UTAUT), the result of an integration of eight previous models which aimed to explain the same phenomenon (acceptance/use of information technology). The research approach was a quantitative and qualitative. To achieve the study objectives were made five semi-structured interviews and an online questionnaire (websurvey) in a valid sample of 101 public employees scattered throughout the country. The technique used to the analysis of quantitative data was the structural equation modeling (SEM), by the method of Partial Least Square Path Modeling (PLS-PM). To qualitative data was the thematic content analysis. Among the results, it was found that, in the context of public service, the degree whose the individual believes that the use of an AVA will help its performance at work (performance expectancy) is a factor to its intended use and also influence its use. Among the results, it was found that the belief which the public employee has in the use of a VLE as a way to improve the performance of his work (performance expectation) was determinant for its intended use that, in turn, influenced their use. It was confirmed that, under the voluntary use of technology, the general opinion of the student s social circle (social influence) has no effect on their intention to use the VLE. The effort expectancy and facilitating conditions were not directly related to the intended use and use, respectively. However, emerged from the students speeches that the opinions of their coworkers, the ease of manipulate the VLE, the flexibility of time and place of the distance learning program and the presence of a tutor are important to their intentions to do a distance learning program. With the results, it is expected that the managers of the distance learning program of ENAP turn their efforts to reduce the impact of the causes of non-use by those unwilling to adopt voluntarily the e-learning, and enhance the potentialities of distance learning for those who are already users
