Canine retraction and anchorage loss Self-ligating versus conventional brackets in a randomized split-mouth study

Objective: To evaluate the velocity of canine retraction, anchorage loss and changes on canine and first molar inclinations using self-ligating and conventional brackets.Materials and Methods: Twenty-five adults with Class I malocclusion and a treatment plan involving extractions of four first premolars were selected for this randomized split-mouth control trial. Patients had either conventional or self-ligating brackets bonded to maxillary canines randomly. Retraction was accomplished using 100-g nickel-titanium closed coil springs, which were reactivated every 4 weeks. Oblique radiographs were taken before and after canine retraction was completed, and the cephalograms were superimposed on stable structures of the maxilla. Cephalometric points were digitized twice by a blinded operator for error control, and the following landmarks were collected: canine cusp and apex horizontal changes, molar cusp and apex horizontal changes, and angulation changes in canines and molars. The blinded data, which were normally distributed, were analyzed through paired t-tests for group differences.Results: No differences were found between the two groups for all variables tested.Conclusions: Both brackets showed the same velocity of canine retraction and loss of anteroposterior anchorage of the molars. No changes were found between brackets regarding the inclination of canines and first molars.

A formação do Professor de Línguas de uma Perspectiva Sociocultural

With the development of cognition studies and the awareness that teachers’ previous experiences, knowledge acquired in language teacher education programs and classroom experiences in different contexts shape the ways teachers think and construct their teaching practices, teacher education programs start to understand, from a sociocultural perspective, teachers’ learning as a dialogic process of knowledge co-construction, which is situated and emerges from practices and sociocultural contexts. Considering the relevance of this new perception, this article aims at presenting such theoretical perspective as well as its contributions to language teacher education research and teaching.

Atividades investigativas: o impacto na capacidade de argumentação em alunos do ensino médio sobre eletroquímica

The education research guidelines have shown the important contribution of the investigations that focus on analysis of the discursive dimension of teaching and learning of Science in actual classroom. An interesting proposal to analyze the effectiveness of an educational activity is to assess the potential of investigative activities in the development of argumentation in science classes. Several studies have taken into account the use of argument in the classroom as a way to provide students with new ways to know the science. Argument refers to the process of associating components that play a central role in the construction of explanations, models and theories. In order to investigate the potential of these activities took place the application of investigative activities with third-year high school students, recorded in audio and video, focusing on the development of the argument. The search, conducted ranks as a qualitative research with characteristics of a case study. The arguments collected during the activities contained the students' conceptions about the concepts discussed and all were recorded in audio and video. With the encouragement of the argument by the investigative activity we evaluate the learning experienced by the speech of students. It may be noted that students have appropriated the concept of oxidation involving electron transfer, thus the activity reached the goal, so that was planned, making it effective for the introduction of electrochemical concepts

Educação ambiental e contexto escolar: questões para um programa de pesquisas

In this paper are systematized the discussions conducted by GDP "Research in EA and School Context", in VII EPEA, which have had, as its main axis, themes, authors and theoretical perspectives privileged in research presented at the event and declared themselves affiliated to this GDP. The dialogue with researches from previous meetings and other, aims to deepen the questions posed by the research group. The discussions allowed to identify themes and issues that present themselves as significant and challenging for research in EA in the school context, namely the conversion of schools into sustainable educational spaces; public-private partnerships, with great interest from companies and NGOs in school spaces, waving kits with educational materials produced for the school; lack of investment in public policies for teacher training in EA; tendency to an adherence to critical environmental education, without, however, have clear theoretical and methodological commitments under this option.

Pesquisa em Educação Ambiental: compromisso com a vida

Different environmental disasters registered around the world and their consequences to nature and to the biodiversity, including the human beings, lead us to deal with nature’s mysteries and with our limits In controlling technological apparatus that make us proud enough to think that we can control nature’s processes. These kinds of experiences, considered as a real “being-event”, make us experiment processes of disillusion related to the possibilities of science and technology. Considering this frame and the historical human experiences, one fundamental question is related to our position, our professional and ethical commitments and our responsibilities facing this reality. How can we deal with these facts that are continuously announcing the limits of nature, of science, technologies and our self-limits? As researchers involved with environmental education, it seems plausible for us to ask about the ethical commitments related to our “acts” of investigation. So, considering different and stimulating possibilities opened by intellectual and philosophers who are adding significant contributions to these debates, my proposal for this essay is to invite environmental education researchers to carry on a dialog involving these questions with some perspectives proposed specially by Bakhtin (1895 – 1975) and some other authors affiliated or not to his approach. This seems to be an opportunity which allows us to realize that our commitments as environmental education researchers would be identified with our commitments with life

O dispositivo metodológico e interventivo autoconfrontação e seus usos em pesquisas de educação

This article presents an academic and scientific study about the use of the device methodological and intervening of selfconfrontation in research in post-graduate studies in Education in Brazil. The self-confrontation is a device created by linguist Daniel Faïta and perfected by psychologist Yves Clot. She seeks to capture the multiple discourses and perspectives around a particular craft, integrating researcher and workers to facilitate the installation of a dialectical movement of analysis and production of knowledge about the work, ownership of these knowledge workers and the collective transformation of labor activity. We chose a qualitative approach and the realization of documental analysis of the abstracts of researches that resulted in the production of doctoral theses and dissertations held in Brazil between 1987 and 2011. Were examined studies that had their abstracts gathered and made available by the Coordenadoria de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) on its website. The results show that self-confrontation is used piecemeal studies produced in the area of Education, used primarily to collect data and to give less emphasis to the transformation of the labor process.

Fotografias escolares: a leitura de imagens na história da escola primária

This research consists in photograph reading, more specifically, school photographs related to primary teaching in the city of Campinas, between 1897 and 1950. It is based on a heritage constituted of 55 images that analyzes four categories of photographs: school architecture, student classes, teaching body and school activities, these categories illustrate the discourse about school, human contexts and social relations revealed by those images. The text also focuses the iconography documentation relevance for History of Education research, specially, about educational institutions.
