Análise das avaliações realizadas na disciplina de arquitetura atômica e molecular no curso de química, modalidade a distância da UFRN

The field of education is very rich and allows us to research in various aspects. The area of chemical education has been growing more and more, and an important aspect that has been researching this area is about the learning difficulties of students. The approach of the themes atomic structure and chemical bonds are developed in high school and have many problems that are often brought to higher education becoming an obstacle to the advancement of learning. It is necessary for these initial themes - the atomic structure and chemical bonds - are well understood by the student to the other contents of Chemistry will be understood more easily. This paper aims to describe, analyze errors and difficulties presented in the assessments of the discipline Atomic and Molecular Architecture, the students of the degree course in Chemistry - EAD, with respect to the contents of " Atomic Structure and Chemical Bonding ", by of the assessments made by the students and the Virtual Learning Environment (VLE), taking into account the activities , discussion forum and access to materials . AVA allows obtaining reports which were used to analyze regarding access / participation to assess their contribution to learning and its relation to the final result (pass / fail). It was observed that the most frequent errors in the assessments are related to the early part of the chemistry that is the understanding of atomic structure and evolution models. Students who accessed the extra material and participated in the activities and forums were students who achieved success in the course. Ie, the difficulties were emerging and the use of available teaching strategies, students could minimize such difficulties, making their performance in activities and assessments were better. Was also observed by attending the AVA, the discipline began with a large withdrawal from the page access as well as the frequency of face- evidence from observation in Listing presence of classroom assessments

A construção identitária em um fórum de discussão: um estudo com alunos da EAD

The aim of this study is to highlight the cultural identities of Spanish undergraduate students from Instituto Federal de Educação, Ciência e Tecnologia – IFRN, in integration with Universidade Aberta do Brasil – UAB, in the distance modality, built from utterances produced by them in a forum discussion online. For this, we chose to analyze the thematic forum “Using fragments of the internet is an ethical act?” generated in the first semester of 2011, linked to the Reading and Writing course. The interest of this researcher to highlight the cultural identities of these subjects, in the Virtual Learning Environment, emerged from the contact with this reality, in which it was found that the statements constructed by students were rich in positions, meanings and interactions. By producing their speeches, such subjects nurture a reflection on how we can establish meaning in the interaction created in online teaching as well as on the construction of cultural identities of the subject within that virtual space. The way students participate in the discussion forum represents learning experiences that lead to the construction of cultural identities, which determine the trajectory of the subjects, which makes the identity an ongoing process. Our theoretical reference follows the interdisciplinary approach of Applied Linguistics and is based on the socio-historical model of language, with language construed as a social practice. This study also established an interface with cultural studies, as it uses the concept of cultural identity in postmodernity. Analysis of the utterances lead to plurality, with a multiplicity of identities, as evidenced from the positioning of the subjects, some focused on the agreement, others on the disagreement, or even on the boldness. It was found also in the investigative path that these identities can be constructed and reconstructed if they are immersed in another set of historically determined social practices.

Capital Social e Desenvolvimento Rural: acesso, uso e gestão da água nos Territórios Rurais do Sertão do São Francisco

This study aimed to contribute to the discussion of social capital, seeking to relate that to the access, use and water resources management in the Sao Francisco Vale, specifically in rural areas of the wilderness of San Francisco situated in the State of Bahia and Pernambuco. As, stimulate action possibilities for individuals (family rural) apart by a patrimony public so precious that is water. Besides a theoretical discussion of social capital (networks, trust, participation) and rural development. We applied 387 questionnaires to farmers and some interviews with actors social of territorial forum and committee of the São Francisco basin where it was possible to correlate our variables in order to confirm our hypothesis: social capital is a key element to ensure access, use and management of water for rural families living in irrigated and rainfed areas
