BEHAVIORS AND ATTITUDES IN THE TEACHING AND LEARNING OF GEOMETRY

This paper presents a case study about teaching and learning topics of Geometry that are part of the syllabus of high school courses. Internationally the teaching of Geometry has been the subject of several studies. Nevertheless, research continues to reveal that Geometry is still quite absent from the classrooms, especially in the early years; Geometry is disliked by most students, is misunderstood, and its notation is totally ignored. One of the reasons for this failure is that these issues are addressed superficially in the curriculum of the training teachers of Geometry. This paper describes the experience of teaching Geometry to a class with 90 students in academic year 2014-2015, enumerates some difficulties and behaviors faced by students and teachers, and exposes the results of the academic success

Is there teamwork in the Family Health Program?

O objetivo do estudo foi conhecer como se desenvolve o trabalho em equipe no Programa Saúde da Família. Utilizou-se metodologia qualitativa. Foi realizado no Município de Santo Antonio do Descoberto (GO), com quatro equipes básicas completas há mais de seis meses. Foram feitos grupos focais, em duas etapas, a primeira com elementos de cada equipe individualmente e, posteriormente, com integrantes das quatro equipes. Para a análise, empregou-se a técnica de discurso do sujeito coletivo. Evidenciou-se que os sujeitos representam o trabalho em equipe como a união dos integrantes na busca de um objetivo comum, o processo de trabalho ocorre de forma parcelar, pois as funções se realizam de forma isolada ou compartilhada, mas não interativa ou integrada. A ausência de articulação das ações dificulta que as equipes encontrem espaços para a elaboração de projeto assistencial local que atenda as necessidades mais amplas da população.The objective of the study was to know how team work in the Family Health Program is developed. A qualitative methodology was used. The study was performed in the city of Santo Antonio do Descoberto, in the Brazilian state of Goiás, with four complete basic teams more than six months ago. Focal groups had been formed, in two stages: the first with elements of each team individually, and later, with integrants of the four teams. For the analysis it was used the Discourse of the Collective Subject technique. It was evidenced that the subjects represent the team work as the union of the integrant ones in the search of a common objective. The work process occurs in a fragmented way, once the functions are carried in either an isolated or shared form, but not interactive or integrated. The absence of articulation of the actions becomes difficult that the teams find spaces for the elaboration of a local assistance project that meet the most ample needs of the population

The Dyson-Schwinger equations and the non-perturbative solution of QED: exploring the two-photon-two-fermion irreducible vertex

A minimal truncated set of Dyson-Schwinger equations that allow exploring the non-perturbative regime of QED is derived for a general linear covariant gauge. This minimal set includes the propagators, the the photon-fermion, and the two-photon-two-fermion vertices. If the equations for the first three quantities are exact, to build a closed set of equations, the last one is truncated ignoring further higher-order Green functions. We also show that the truncated equation reproduces the lowest order perturbative result for the two-photon-two-fermion vertex in the limit of the small coupling constant. Then, the two-photon-two-fermion irreducible vertex is studied by combining the corresponding Ward-Takahashi identity with the Dyson-Schwinger equation. The longitudinal part of this irreducible vertex is computed from the Ward-Takahashi identity, which is solved in the low energy limit when one of the photons has zero energy (soft photon limit). For this kinematical configuration, the general expression for the vertex is derived and its form factors related to the photon-fermion vertex and fermion propagator

The influence of material density on bipolar charge transport in polymer-based electronic applications

Using a mesoscopic modelling approach, the authors performed computer experiments to study the influence of polymer density on bipolar charge evolution through thin layers of polydiacetylene (PDA) exhibiting specific microstructures. We found that the competition between charge transport, trapping and recombination within the polymer layer leads to several general trends, some of them being non-intuitive, as one varies polymer density. Our results show that polymer density mainly affects current and recombination efficiencies in the absence of defects or impurity states. The overall trends depend both on chain orientation relative to the electrodes and on the strength of the external applied electric field. These results suggest that adequate modelling of charge transport in electronic and optoelectronic devices based on conducting and semiconducting polymers, such as PDA, must include their structure and related key factors at mesoscopic scale. Such models provide the necessary knowledge-base to optimize the polymer film structure for electronic applications.Fundação para a Ciência e a Tecnologia (FCT) – Programa Operacional “Ciência , Tecnologia, Inovação” – POCTI/CTM/41574/2001 e SFRH/BD/11231/2002Comunidade Europeia (CE).

Nutritional composition of omnivorous and carnivorous wild freshwater fish from Tagus river basin

Portugal is one of the countries in the world with highest per capita fish consumption (59.9 kg/year) (1), mainly saltwater fish from Atlantic Northwest and marine aquaculture. However, in the interior of Portugal is traditional the consumption of wild freshwater fish (common carp [CC], iberian barbel [IB], crucian carp [CrC] and largemouth bass [LB]). These species are very interesting as game fishing and also very important in the local cuisine due to their characteristic flavor.CERNAS-IPCB [UIDB/00681/2020] funding by the Portuguese National Funding Agency for Science, Research and Technology (FCT).info:eu-repo/semantics/publishedVersio

Major roads have a negative impact on the Tawny Owl Strix aluco and the Little Owl Athene noctua populations

The increasing road networks threaten ecosystems by direct effects such as increased mortality due to collision with vehicles and by various indirect effects leading to road avoidance. We censused Tawny Owls Strix aluco and Little Owls Athene noctua in 2005, 2007 and 2009 in a rural landscape in Southern Portugal in order to study the effects of roads and habitat characteristics on Tawny Owl density and Little Owl presence. The presence of both owl species in the 70 census locations was coherent among years. Our results showed that Tawny Owl density near major roads was lower, with the negative effects extending possibly up to 2 km. The probability of Little Owl presence was also negatively affected by the proximity to major roads. The negative effects of roads were significant even considering habitat preferences and spatial autocorrelation, which had the most marked effect on the density or presence of both owls. The reduced occupancy by Tawny Owls and Little Owls of habitats near major roads may be caused by several factors, including increased mortality, disturbance caused by high traffic density, and increased fragmentation. Traffic noise in particular may affect intra-specific communication and hunting efficiency. Consequently, habitat near roads may represent lower-quality territories for owls

The knowledge and information in the connectivism theory

On the context of technological development and society organized on network, appears the learning theory for the digital age, the connectivism. It is about of a Siemens and Downes proposed, in 2004, that highlights the knowledge as result of established connections on the networks, what allows the capacity of reflection, deciding and sharing. In this context, it objectifies with this article searching the theoretical panorama of thematic about connectivism and its relation with knowledge and information. There is a search of quality approach and of exploratory nature that comes out of a Systematic Review of Literature adapted of Cochran Center. As result, it was observed that, on the searched basis, the number of publications in the period of 2011 to 2017 had the balance in total occurrences compared to the types of documents, events articles and periodicals, with a higher incidence of publication in 2015. For the paucity of thematic it was observed that has discussions about what refers the legitimacy of a theory for the connectivism
