Teachers Formation in Higher Education: Some Aspects under the Light of Education-Work Relations

This text is mainly aimed to address essential aspects of teacher formation in the light of education-work relations in the higher education, from our systematic experience in higher education teaching, particularly teaching and research in the field of Didactics discipline. This formulation is justified considering our concern in seeking to situate this discussion in the context of bringing together knowledge areas and the field of teaching knowledge. Still, our choice to develop such an approach in the light of work-education relationship is due to the belief about the possibilities of seeking to overcome the requirements imposed by capitalism to our educational system, within the possible contradictions of these relationships. In this context the teachers’ formation in higher education gains social and strategic importance, taking on the task of forming individuals of “action-reflection-action” in a society established historically based on the social relations which settle in the light of capital’s multiple determinations. It appears that, in this sense, the major confrontations have been given within the discussions about what to prioritize or combine in the list of criteria and content for teacher’s formation. In Didactic, we seek to emphasize discussions that we consider with a philosophical background, referring to the orientation of teaching practice in knowledge of contemporary ideological struggle; socio-historical, referring to the possibility of formation of disciplines, among them Didactic, and curriculums and references to support its guidance in the process of teacher’s formation. This context of discussion is based on the concrete teaching practice with a view to transformation and to search for new syntheses in terms of knowledge and in terms of historical reality. Then therefore, our methodological approach grounded in the dimensions of the same unit: historical materialism as posture, method and as praxis.

Permian stromatolites associated with bivalve coquina beds-Angatuba, SP, Brazil (Teresina Formation, Parana Basin)

Silicified stromatolites have been described in the Permian Teresina Formation, Passa Dois Group, of the Parana Basin. These stromatolites occur as blocks in the Fazenda Monte Alegre area at the headwaters of the creek known as Corrego Catanduva in the municipality of Angatuba. These blocks originate from the Serra de Angatuba region and were recognized in a road that was cut in the midst of sandstones and siltites. The stromatolites are isolated bioherms that are domed to subspherical with a flat base in profile and a rounded to lenticular shape in plan view. The stromatolites exhibit a reddish coloration and are composed of microcrystalline quartz. Lamination is continuous, non-columnar, and anastomosed, showing parallel to divergent growth; however, divergent columns also occur, especially at the tops of the bioherms. The lamination is fine and well preserved, with alternating light and dark laminas. Microfossils of filamentous cyanobacteria are preserved and were related to the genera Microcoleus and Rivularia. Silicified bivalves occur in association with the stromatolites and are preserved in the form of coquina beds and rare isolated specimens within the bioherms. The described specimens belong to the Pinzonella illusa biozone, with representatives of the species Pinzonella illusa, Angatubia cowperesioides, and Houldausiella elongata. The formation environment of these stromatolites is associated with tidal plains of shallow, brackish, relatively calm, warm waters of good luminosity with the presence of weak currents. There was likely a low level of predation, and the environment may have been hypersaline. The coquina beds associated with the stromatolites indicate a probable proximal tempestite, i.e., they were formed near the coastline. The stromatolites were originally composed of carbonates, although these were replaced by silica during early diagenesis.

Professor de língua estrangeira para crianças: conhecimentos teórico-metodológicos desejados

Tem aumentado o interesse pelo domínio da língua inglesa como ferramenta de comunicação para inclusão no mundo globalizado, bem como a oferta de seu ensino para crianças (CAMERON, 2001; PINTER, 2006). Neste texto, buscamos refletir acerca da formação do docente para atuar junto a esse público em especial. Trazemos sugestões de mudanças no processo vigente, que venham ao encontro das necessidades contemporâneas (SACRISTÁN, 2006; LIBÂNEO, 2006), mediante a visão de cinco professoras que lecionam língua inglesa para crianças em um município matogrossense. Os dados fazem parte de um estudo qualitativo e foram gerados por meio de entrevistas individuais e sessões reflexivas coletivas entre o grupo de docentes e a pesquisadora. Com base em seus dizeres, apresentamos os conhecimentos teórico-metodológicos adquiridos e os desejados, e algumas características peculiares a esses docentes (SPADA, 2004). São abordadas, também, algumas dificuldades encontradas e a importância da experiência para o desenvolvimento da docência. A formação é entendida como contínua, com caráter coletivo, colaborativo e reflexivo (PORTO, 2004; IMBERNÓN, 2005; PIMENTA e GHEDIN, 2005), possibilitando ao docente desenvolver ação investigativa de sua prática pedagógica.

Ultrastructural and histochemical examination of alveolar bone at the pressure areas of rat molars submitted to continuous orthodontic force

It is usually believed that repair in alveolar bone during orthodontic movement occurs after decreasing of force. However, we have recently observed signs of repair in previously resorbed cementum from human teeth exposed to continuous forces. In order to test the hypothesis that bone resorption and deposition occur concomitantly at the pressure areas, a continuous 15 cN force was applied in a buccal direction to upper first molars from eight 2.5-month-old male Wistar rats for 3 d (n=4) and 7 d (n=4). As a control, two additional rats did not have their molars moved. Maxillae were fixed in 2% glutaraldehyde + 2.5% formaldehyde, under microwave irradiation, decalcified in ethylenediaminetetraacetic acid, and processed for transmission electron microscopy. Specimens from one rat from each group were processed for tartrate-resistant acid phosphatase (TRAP) histochemistry. At both the times studied, the alveolar bone surface at the pressure areas showed numerous TRAP-positive osteoclasts, which were apposed to resorption lacunae. In addition, osteoblasts with numerous synthesis organelles were present in the neighboring areas overlying an organic matrix. Thus, this study provides evidence that the application of continuous forces produces concomitant bone resorption and formation at the pressure areas in rat molars.

Formation of SnO2 gels from dispersed sols in aqueous colloidal solutions

Transparent SnO2 gels were obtained from SnCl4 aqueous solution. The sol formation from tin oxihydroxy peptization in different concentrations and by electrolyte addition in solution was measured. It was verified that the residual presence of chloride ions compromises the colloidal system stability. The sol-gel transition was investigated as a function of the quantity of solid particles in the aqueous environment and of aging time at 60°C by infrared spectroscopy and rheological measurements. The transition from plastic to pseudoplastic flow observed with the increase in loading suggests that a continuous and three-dimensional network formation is closely related to hydrogen bridges and/or hydrogen clusters, culminating in the gel formation. © 1990.

Continuous production of metal matrix composites from the semisolid state

Continuous strip metal matrix composite (MMC) casting of 0.3 mm diameter hard-drawn stainless steel (316L) wire in a quasi-eutectic SnPb (64Sn36Pb) matrix was performed by a two-roll melt drag processing (TRMDping) method, with the wire being dragged through a semisolid puddle with a fibre contact time of approximately 0.2 s. A slag weir placed at the nozzle contained two wire guide holes: one located near the upper roll, and the other located between the rolls. A successful continuous composite strip casting with good fibre alignment was achieved by inserting and embedding the wire into the matrix using the guide hole between the rolls. Degeneration of eutectic/dendrite structures led to the formation of globular structures. The occurrence and formation mechanisms of cracks, de-lamination and voids in the matrix were discussed. TRMDping is economically viable and has significant benefits over other MMC fabrication methods. © (2013) Trans Tech Publications, Switzerland.

Spirituality: Do teachers and students hold the same opinion?

Background:  Few studies have investigated potential differences between the opinions of educators and undergraduates regarding spirituality in patient care. Understanding these differences, could lead to better strategies for educational proposes. Purpose:  To compare the opinions of medical teachers (MTs) and medical students (MSs) regarding spirituality training in a Brazilian medical school. Methods:  A cross-sectional study was conducted. MTs and MSs filled out a questionnaire containing the Duke Religion Index, and questions regarding spirituality in clinical practice and at medical school. A comparison between early-curriculum MSs, late curriculum MSs and MTs was carried out. Chi-square (categorical) and Mann-Whitney (continuous/ordinal) tests were used. Results:  A total of 475 MSs and 44 MTs were evaluated. Results showed that MSs did not address spirituality as frequently as MTs (p<0.001), and that most participants did not feel prepared to address this issue, and believe that Brazilian medical schools are not giving all the required information in this field. Nevertheless, they believe MSs should be prepared to discuss these issues. Late-curriculum MSs believed that spirituality plays a more positive role in patient health (p=0.027), and were more prone to address this issue than early-curriculum MSs (p=0.023). Conclusion:  These findings revealed some of the challenges faced by spirituality medical training in Brazil, and differences between MTs and MSs regarding this issue. Further studies are needed to replicate these findings in other countries. © Blackwell Publishing Ltd 2013.
