O trabalho coletivo do Departamento de Educação Física e a gestão da ecologia das aulas : a integração da agenda social dos alunos nas decisões de planeamento e ação dos professores

O estudo das condições que potenciam o ensino-aprendizagem em educação física precisa de considerar mais consistentemente e explicitamente as evidências do mesossistema estabelecido entre as ecologias do trabalho colaborativo do grupo disciplinar e as das suas aulas. Especificamente, incita-se à compreensão como a negociação integradora do sistema social dos alunos pode ser potenciada pelo grupo disciplinar. Para alcançar essa compreensão articularam-se os modelos das comunidades de aprendizagem profissional e da ecologia da aula, através da bioecologia do desenvolvimento humano. Conduziu-se um desenho de estudo de caso longitudinal integrado, triangulando métodos, fontes e dados de um grupo disciplinar de educação física com qualidade colaborativa. Simultaneamente, observaram-se duas ecologias de aulas de educação física, diferenciadas pelas disposições de negociação dos respetivos professores, detalhando paralelamente os perfis de agenda social dos alunos para essas ecologias. Os resultados permitem salientar a interação das propriedades Pessoa-Contexto-Processo-Tempo como condições mesossistémicas favorecedoras da integração do sistema social dos alunos, nomeadamente: as caraterísticas do grupo como comunidade de aprendizagem profissional focada na integração; a interação macrossistémica e a alternância intencional cíclica grupo-aula; e a articulação entre o desenvolvimento curricular colaborativo e a partilha e produção de conhecimento em espirais curriculares plurianuais e anuais. Estas condições refletiram-se nas ecologias das aulas como semelhanças tendencialmente integradoras do sistema social na instrução e na organização. Todavia, também emergiram particularidades em cada ecologia traduzidas numa congruência mais consistente entre os perfis de agenda social encontrados para o envolvimento integrador, por associação às diferenças de alinhamento instrucional na negociação pelos professores. Este estudo lança implicações para a investigação relacionadas com a verificação e aprofundamento das condições mesossistémicas identificadas. Paralelamente, a prática profissional de professores e de formadores de professores encontra implicações sobre a melhoria da qualidade colaborativa profissional para promover continuamente melhores experiências de ensino-aprendizagem da educação física nos microssistemas aqui analisados.

The effect of host social system on parasite population genetic structure: comparative population genetics of two ectoparasitic mites and their bat hosts.

BACKGROUND: The population genetic structure of a parasite, and consequently its ability to adapt to a given host, is strongly linked to its own life history as well as the life history of its host. While the effects of parasite life history on their population genetic structure have received some attention, the effect of host social system has remained largely unstudied. In this study, we investigated the population genetic structure of two closely related parasitic mite species (Spinturnix myoti and Spinturnix bechsteini) with very similar life histories. Their respective hosts, the greater mouse-eared bat (Myotis myotis) and the Bechstein's bat (Myotis bechsteinii) have social systems that differ in several substantial features, such as group size, mating system and dispersal patterns. RESULTS: We found that the two mite species have strongly differing population genetic structures. In S. myoti we found high levels of genetic diversity and very little pairwise differentiation, whereas in S. bechsteini we observed much less diversity, strongly differentiated populations and strong temporal turnover. These differences are likely to be the result of the differences in genetic drift and dispersal opportunities afforded to the two parasites by the different social systems of their hosts. CONCLUSIONS: Our results suggest that host social system can strongly influence parasite population structure. As a result, the evolutionary potential of these two parasites with very similar life histories also differs, thereby affecting the risk and evolutionary pressure exerted by each parasite on its host.

Communally breeding Bechstein's bats have a stable social system that is independent from the postglacial history and location of the populations.

Investigating macro-geographical genetic structures of animal populations is crucial to reconstruct population histories and to identify significant units for conservation. This approach may also provide information about the intraspecific flexibility of social systems. We investigated the history and current structure of a large number of populations in the communally breeding Bechstein's bat (Myotis bechsteinii). Our aim was to understand which factors shape the species' social system over a large ecological and geographical range. Using sequence data from one coding and one noncoding mitochondrial DNA region, we identified the Balkan Peninsula as the main and probably only glacial refugium of the species in Europe. Sequence data also suggest the presence of a cryptic taxon in the Caucasus and Anatolia. In a second step, we used seven autosomal and two mitochondrial microsatellite loci to compare population structures inside and outside of the Balkan glacial refugium. Central European and Balkan populations both were more strongly differentiated for mitochondrial DNA than for nuclear DNA, had higher genetic diversities and lower levels of relatedness at swarming (mating) sites than in maternity (breeding) colonies, and showed more differentiation between colonies than between swarming sites. All these suggest that populations are shaped by strong female philopatry, male dispersal, and outbreeding throughout their European range. We conclude that Bechstein's bats have a stable social system that is independent from the postglacial history and location of the populations. Our findings have implications for the understanding of the benefits of sociality in female Bechstein's bats and for the conservation of this endangered species.

Spatio-temporal population genetic structure of the parasitic mite Spinturnix bechsteini is shaped by its own demography and the social system of its bat host.

Information about the population genetic structures of parasites is important for an understanding of parasite transmission pathways and ultimately the co-evolution with their hosts. If parasites cannot disperse independently of their hosts, a parasite's population structure will depend upon the host's spatial distribution. Geographical barriers affecting host dispersal can therefore lead to structured parasite populations. However, how the host's social system affects the genetic structure of parasite populations is largely unknown. We used mitochondrial DNA (mtDNA) to describe the spatio-temporal population structure of a contact-transmitted parasitic wing mite (Spinturnix bechsteini) and compared it to that of its social host, the Bechstein's bat (Myotis bechsteinii). We observed no genetic differentiation between mites living on different bats within a colony. This suggests that mites can move freely among bats of the same colony. As expected in case of restricted inter-colony dispersal, we observed a strong genetic differentiation of mites among demographically isolated bat colonies. In contrast, we found a strong genetic turnover between years when we investigated the temporal variation of mite haplotypes within colonies. This can be explained with mite dispersal occuring between colonies and bottlenecks of mite populations within colonies. The observed absence of isolation by distance could be the result from genetic drift and/or from mites dispersing even between remote bat colonies, whose members may meet at mating sites in autumn or in hibernacula in winter. Our data show that the population structure of this parasitic wing mite is influenced by its own demography and the peculiar social system of its bat host.

Exploring the use of cooperative activities in a language subject to develop students’ social competences at the University

Cooperative learning has been successfully implemented in the last 60 years for teaching at different educational levels including the Higher Studies due to its solid theoretical foundation, the principles it proposes and its practical applications. The purpose of this article is to offer a proposal for some cooperative activities that allow students to work in small groups in a language subject in order to learn not only contents but also putting into practice what they learn, i.e., they learn by being active. This article discusses how the said activities make it possible for students to work with the main principles of cooperative learning, i.e.: positive interdependence, face-to-face interaction, individual and group accountability, interpersonal and small-group skills and group processing. Moreover, this research will also point out that the proposed activities allow students to acquire some of the social competences required in the labour market such as leadership, conflict solving and cooperation.

The effect of reciprocal mapping on high-risk sixth-grade students' social studies achievement

Reading deficits in students in Grades 4 to 12 are evident in American schools. Informational text is particularly difficult for students. This quasi-experimental study (N=138) investigated sixth-grade students' achievement in social studies using the Reciprocal Mapping instructional routine, compared to sixth-grade students' achievement taught with a traditional approach. The Reciprocal Mapping instructional routine incorporated explicit instruction in text structure using graphic organizers. Students created their own graphic organizers and used them to write about social studies content. The comparison group used a traditional approach, students' reading the textbook and answering questions. Students for this study included sixth-graders in the seven sixth-grade classrooms in two public schools in a small, rural south Florida school district. A focus of this study was to determine the helpfulness of the intervention for at-risk readers. To determine students considered to be at-risk, the researcher used data from the reading portion of the Florida Comprehensive Assessment Test (FCAT), 2011-2012, that considers Level 1 and 2 as at-risk readers. The quasi-experimental study used a pretest-posttest control group design, with students assigned to treatment groups by class. Two teachers at the two rural sites were trained on the Reciprocal Mapping instructional routine and taught students in both the experimental and control groups for an equivalent amount of time over a 5-week period. Results of the 3 x 2 factorial ANCOVA found a significant positive difference favoring the experimental group's social studies achievement as compared to that of the comparison group as measured by the pre/post unit test from the social studies series (McGraw-Hill, 2013), when controlling for initial differences in students' reading FCAT scores. Interactions for high-risk struggling readers were investigated using the significance level p < .05. Due to no significant interaction the main effects of treatment were interpreted. The pretest was used as a covariate and the multivariate analysis was found to be significant. Therefore, analysis of covariance was run on each of the dependent variable as a follow-up. Reciprocal Mapping was found to be significant in posttest scores, independent of gender and level of risk, and while holding the pretest scores constant. Findings showed there was a significant difference in the performance of the high-risk reading students taught with the Reciprocal Mapping intervention who scored statistically better than students in the control group. Further study findings showed that teacher fidelity of implementation of the treatment had a statistically significant relationship in predicting posttest scores when controlling for pretest scores. Study results indicated that improving students' use of text structure through the Reciprocal Mapping instructional routine positively supported sixth-grade students' social studies achievement.

Education in the halls : students' perspectives on cultural expression and resistance

This research is a qualitative study of cultural reproduction and resistance from students' perspectives. Thirteen teenagers (eight in attendance in regular high schools and five drop-outs) were recruited to take part and were involved to varying degrees through interviews, journal writing, and group interactive sessions. A purposive sampling design was used initially to recruit individuals known to the researcher through contacts in an alternate education setting. Other participants were recruited throughout the research phase. The theoretical aspects are premised on the work of Paul Willis, Michel Foucault, and Pierre Bourdieu. The reflexive praxeology of Bourdieu reflects the position taken as one way of understanding how students construct and respond to the situations of cultural dominance they experience in schools. The same reflexivity is offered for suggestions as to how teachers can respond to their own position in the education system.

Formação e leitura : o professor, sua prática e a inclusão social

“Formação e Leitura: o Professor, sua Prática e a Inclusão Social” aborda a problemática do fazer pedagógico para formar leitores ‘competentes’ favorecendo a inclusão social e a formação de cidadãos críticos. Pesquisa de natureza qualitativa, mas que não descarta dados quantitativos adota como fundamento metodológico a abordagem qualitativa de pesquisa, num recorte para estudo de caso. Objetiva conhecer e traçar um perfil da formação dos professores atuantes no Ensino Fundamental I, da rede de ensino público municipal de Cotia – São Paulo, identificar as concepções do professor a respeito deste ensino e aprendizagem, compreender e apresentar a relação dos professores e alunos em torno desta prática e sua qualidade social. As considerações a respeito da importância da leitura, as práticas pedagógicas e atuação do professor como incentivador e disseminador do hábito de ler e a formação necessária para que sejam comprometidos com o desenvolvimento desta prática social, constituem os questionamentos que norteiam esta pesquisa. Dentre os resultados, constata que o universo de significações trazido pelos professores recaem sobre a prática docente; são os seus hábitos e crença na leitura, como fator de inclusão social sua e de seus alunos que determinam o seu fazer pedagógico. Essa pesquisa tem o potencial de contribuir para reflexões dos projetos pedagógicos e suas equipes escolares, visando elevar a qualidade social da educação de um modo geral.

Perceptions of Social Mobility in Community College Scholars at Bucknell University

While national leaders have joined the discussion more recently, scholars in the fields of education, psychology, and sociology, have been exploring the ways in which students? socioeconomic background affects the outcomes they experience as a result of their education (Lareau, Unequal Childhoods: Class, Race, and Family Life, 2003).Furthermore, the role played by the education system in creating or diminishing socioeconomic disparity has also been studied in depth (Bourdieu, 1977; Boudon, 1977). However, the journeys of students from low-income families that begin their education at community colleges and continue it, through careful planning or chance, at elite four-year institutions, has not been the subject of much attention. This thesis explores these students? perceptions of social mobility as they have been shaped by their experiences so far in life. This includes the exploration of changes in their perceptions as the contexts for their lives have been changed. Quantitative analysis of survey results and qualitative analysis of participant interviews serve as the data set for this study. The implications ofthe findings for student affairs practitioners are also explored.

A Social Cognitive Approach to Coping with Acculturative Stress in International Students

The present study employed a cross-sectional design to test a model of coping with acculturative stress in an international student sample. Drawing from Lent’s (2004) social cognitive model of restorative well-being, several direct and mediated paths were hypothesized to predict (negatively) acculturative stress and (positively) life satisfaction. Behavioral acculturation and behavioral enculturation (Kim & Omizo, 2006) were also examined as predictors of coping with acculturative stress among international students. Using a self-report survey, participants’ ratings of acculturative stress, life satisfaction, social support, behavioral acculturation, behavioral enculturation, and coping self-efficacy were assessed. The results revealed that the variables of the model explained 16% of the variance in acculturative stress and 27% of the variance in life satisfaction. A final model, including the use of modification indices, provided good fit to the data. Findings also suggested that coping self-efficacy was a direct predictor of acculturative stress, and that behavioral acculturation and coping self-efficacy were direct predictors of students’ life satisfaction. Limitations, future research, and practical implications are discussed.

The Role of Attachment in a Social Cognitive Model of Social Domain Satisfaction in College Students

The study examined a modified social cognitive model of domain satisfaction (Lent, 2004). In addition to social cognitive variables and trait positive affect, the model included two aspects of adult attachment, attachment anxiety and avoidance. The study extended recent research on well-being and satisfaction in academic, work, and social domains. The adjusted model was tested in a sample of 454 college students, in order to determine the role of adult attachment variables in explaining social satisfaction, above and beyond the direct and indirect effects of trait positive affect. Confirmatory factor analysis found support for 8 correlated factors in the modified model: social domain satisfaction, positive affect, attachment avoidance, attachment anxiety, social support, social self-efficacy, social outcome expectations, and social goal progress. Three alternative structural models were tested to account for the ways in which attachment anxiety and attachment avoidance might relate to social satisfaction. Results of model testing provided support for a model in which attachment avoidance produced only an indirect path to social satisfaction via self-efficacy and social support. Positive affect, avoidance, social support, social self-efficacy, and goal progress each produced significant direct or indirect paths to social domain satisfaction, though attachment anxiety and social outcome expectations did not contribute to the predictive model. Implications of the findings regarding the modified social cognitive model of social domain satisfaction were discussed.

Emoções mistas: integração social e académica dos alunos provenientes dos PALOP

RESUMO: A presente investigação teve como objectivo, conhecer as experiências emocionais que caracterizam os estudantes dos PALOP ao saberem que vão entrar no Ensino Superior em Portugal e durante o primeiro semestre; verificar se as emoções sentidas durante a frequência do primeiro semestre estão relacionadas com a sua integração social e académica. Participaram 100 alunos oriundos dos PALOP no primeiro ano do ensino superior português, de diferentes estabelecimentos de Ensino Superior, com idades entre os 20 e os 50 anos. Nesta investigação foram utilizados como instrumentos de medidas, as seguintes medidas: um Questionário sócio-demográfico, um questionário de experiências emocionais (Russell & Carroll); Escala de Emoções Mistas (AES, Carrera & Oceja, 2007); Teste de Positividade (Fredrickson, 2009); Escala de Integração Social e Académica (ISA, Silva; Abrantes, & Duarte (2009) e a Escala de Integração Social no Ensino Superior (EISES, Diniz & Almeida 2005). Concluímos assim que as emoções mistas mais sentidas são alegria e medo, assim como alegria e tristeza. Foi ainda possível concluir que o processo de integração está relacionado com um maior rácio da positividade na frequência do primeiro semestre. ABSTRACT: The objective of the present investigation is to know the emotional experiences that characterize the students of the African Countries with Portuguese as the Official Language while knowing that they are going to enter in the Superior Teaching in Portugal and during the first semester; to check if the emotions felt during the frequency of the first semester are connected with his social and academic integration. The participants were 100 pupils originating from the African Countries with Portuguese as the Official Language in the first year of the superior Portuguese teaching, of different establishments of Superior Teaching, with ages between the 20 and 50 years. In this investigation we used the following measures: a Questionnaire demographic-partner, a questionnaire of emotional experiences (Russell & Carroll); Analogical Emotional Scale (AES, Carrera & Oceja, 2007); Positivity Self-Test (Fredrickson, 2009); Scale of Social and Academic Integration (ISA, Silva, Abrantes, & Duarte, 2009) and the Scale of Social Integration in the Superior Teaching (EISES, Diniz & Almeida 2005). We concluded that the most felt mixed emotions are joy and fear, as well as joy and sadness. It was also possible to conclude that the process of integration is connected with a bigger ratio of the positivity during the frequency of the first semester.
