A competência global na aula de língua inglesa : como preparar os alunos para viver e agir no mundo atual?

Este estudo teve como principais objetivos compreender os efeitos de um projeto de educação global nos conhecimentos, capacidades e atitudes de um grupo de alunos portugueses do 11.º ano, bem como compreender as potencialidades da aula de língua inglesa no âmbito de uma educação promotora da participação ativa numa sociedade globalizada. Tratando-se de um estudo de tipo investigação-ação, ancorado no paradigma socio-crítico, foram recolhidos dados através de questionários, aplicados aos alunos antes e após o projeto de intervenção, de gravações vídeo de quatro sessões de educação global e de uma entrevista realizada à professora cooperante. Recorreu-se ainda à recolha documental de trabalhos dos alunos, bem como do Programa de Inglês (continuação) dos 10.º, 11.º e 12.º anos. A análise dos dados recolhidos, efetuada segundo diferentes métodos e instrumentos, permitiu concluir que o projeto de educação global teve efeitos mais significativos no desenvolvimento dos conhecimentos dos alunos, sobretudo relacionados com problemas globais específicos, tendo estes compreendido que o que acontece em outros locais tem relevância na vida de cada um. O estudo permitiu ainda verificar que as aulas de língua inglesa são o espaço ideal para se trabalhar a educação global, funcionando como uma porta aberta para outras línguas, culturas e mundivisões. Estes resultados sugerem que é possível e necessário promover o desenvolvimento da competência global na aula de línguas, mobilizando e incorporando saberes e recursos que valorizem capacidades de trabalho colaborativo, de comunicação e de resolução de problemas, bem como atitudes de respeito pelos Outros, imprescindíveis para o exercício da cidadania e para desafiar as injustiças e desigualdades que nos rodeiam.

Neuromuscular adaptations in football athletes with prior history of hamstring strain injury

Background: Hamstring strain injuries (HSI) are one of the most common injuries in a wide variety of running-sports, resulting in a considerable loss of competition and training time. One of the most problematic consequences regarding HSI is the recurrence rate and its non-decrease over the past decades, despite increasing evidence. Recent studies also found several maladaptations post-HSI probably due to neuromuscular inhibition and it has been proposed that these adaptations post-injury may contribute as risk factors for the injury-reinjury cycle and high recurrence rates. Furthermore it has been recently proposed not to disregard the inter-relationship between these adaptations and risk-factors post-injury in order to better understand the mechanisms of this complex injury. Objective: To determine, analyze and correlate neuromuscular adaptations in amateur football players with prior history of HSI per comparison to uninjured athletes in similar conditions. Methodology: Every participant was subjected to isokinetic concentric (60 and 240deg.sec) and eccentric (30 and 120deg.sec¯¹) testing, and peak torque, angle of peak torque and hamstrings to quadriceps (H:Q) conventional ratios were measured, myoelectrical activity of Bicep Femoris (BF) and Medial Hamstrings (MH) were also measured during isokinetic eccentric testing at both velocities and muscle activation percentages were calculated at 30, 50 and 100ms after onset of contraction. Furthermore active and passive knee extension, knee joint position sense (JPS) test, triple-hop distance (THD) test and core stability (flexors and extensors endurance, right and left side bridge test) were used and correlated. Results: Seventeen players have participated in this study: 10 athletes with prior history of HSI, composing the Hamstring injury group (HG) and 7 athletes without prior severe injuries as control group (CG). We found statistical significant differences between HG injured and uninjured sides in the BF myoelectrical activity at almost all times in both velocities and between HG injured and CG non-dominant sides at 100ms in eccentric 120deg.sec¯¹ velocity (p<.05). We found no differences in MH activity. Regarding proprioception we found differences between the HG injured and uninjured sides (p=.027). We found no differences in the rest of used tests. However, significant correlation between myoelectrical activation at 100ms in 120deg.sec¯¹ testing and JPS with initial position at 90º (r-.372; p=0.031) was found, as well as between isokinetic H:Q ratio at 240deg.sec and THD score (r=-.345; p=.045). Conclusion: We found significant differences that support previous research regarding neuromuscular adaptations and BF inhibition post-HSI. Moreover, to our knowledge, this was the first study that found correlation between these adaptations, and may open a door to new perspectives and future studies.
