As percepções de alunos, professores e encarregados de educação sobre a disciplina de educação musical: Um estudo de caso no âmbito do 2º ciclo do ensino básico

Este estudo teve como grande finalidade conhecer as percepções de alunos do 2° Ciclo do Ensino Básico de uma escola da periferia de Lisboa e dos respectivos professores e encarregados de educação, relativamente à disciplina de Educação Musical. No estudo foi utilizado um desenho metodológico de cariz naturalista, com aproximação ao estudo de caso, em que a técnica de recolha de dados de suporte foi o inquérito por questionário, aplicado aos três elementos da comunidade educativa antes referidos. Os principais objectivos do estudo foram, entre outros, os seguintes: #) Conhecer a importância que é dada à Educação Musical, enquanto disciplina integrante do currículo escolar, por alunos, professores e encarregados de educação; #) Contribuir para uma tomada de consciência, por parte da comunidade educativa em geral, sobre a importância da Educação Musical na formação integral do cidadão. A análise dos resultados obtidos permitiu chegar a diversas inferências e conclusões, destacando-se, entre outras, as seguintes: - Em relação aos alunos, a Educação Musical foi por eles considerada uma disciplina razoavelmente importante para a sua formação face à qual afirmaram nutrir algum interesse, sobretudo quando nela são promovidas actividades práticas; - No que diz respeito aos professores, estes consideraram, na sua maioria, que a disciplina, apesar das suas potencialidades formativas, acaba por não ser aproveitada na sua plenitude; - Os encarregados de educação tenderam a considerá-la uma disciplina importante, parecendo estar informados sobre as actividades e as funções a ela associadas. A música pareceu, além disso, fazer parte da vida da maior parte dos inquiridos dos três grupos participantes no estudo, tendo os mesmos indicado que ouviam música todos os dias e que já haviam assistido a, pelo menos, um concerto ao vivo. ABSTRACT; The aim of this study was to acknowledge the perceptions of students of the fifth and sixth grades of a Basic school in Lisbon periphery, their parents and teachers, about the subject of Musical Education. ln that purpose, we are in front of a naturalist investigation, approaching the case study, were the support instrument of data collecting was the questionnaire, applied to the three members of the educative community we have already referred to. This study had, as main goals, the following, among others: #) To know the importance that is given to Musical Education, as a subject which is part of the school curriculum, by students, parents and teachers; #) To contribute for the acknowledgement, by the general educative community, of the importance of Musical Education, for the growth and formation of the individuals. The analisys of the results allowed us to reach, among others, several conclusions and inferences: - Concerning the students, musical education was considered a subject of reasonable importance for their formation, and by which they showed some interest, especially when teachers promote practical activities; - The majority of the teachers considered that the subject was very important for the formation of the individual. However, and in spite of its formative potentialities, musical education is not applied and used as much as it should be; - Parents seem to consider it an important subject and also seem to be well informed about the activities and functions associated to it; Music seemed to be part of the lives of all the inquiries, who revealed listening to music every day and, in the majority of cases, have already been to a live concert.

Chemical composition and pharmacological activities of essential oils of Lavandula spp.

Lavandula spp. belong to the family Lamiatae and some species are often used in popular medicine and have been used for centuries in a large number of medical applications and in aromatherapy. Although similar ethnobotanical properties of Lavandula spp., its essential oils, general chemical composition and therapeutic applications differ from different species. Lavandula stoechas L. subsps. luisieri (Rozeira) Rozeira and L. viridis L’Hér are endemic to the Iberian Peninsula, widespread in the South of Portugal, namely in Southern Alentejo and Algarve. The aim of our study was evaluate the chemical composition and toxicological and pharmacological activities of leaves essential oils of spontaneous plants of L. stoechas L. subsps. luisieri (Alentejo) and L. viridis (Algarve). The essential oils of these wild plants, collected in spring, were obtained by hydrodistillation in a Clevenger-type apparatus and its chemical composition was evaluated by GC/FID. The acute toxicity of essential oils was evaluated "in vitro" using brine shrimp (LC50) and "in vivo" using Swiss mice (DL50). The analgesic and anti-inflammatory pharmacological properties of L. stoechas subsp. luisieri essential oil were evaluated in mouse or rats by the Amour-Smith and carrageen-induced paw edema tests, respectively. Results showed important differences in chemical composition of essential oils from two species analyzed either to diversity and proportion of its constituents. The essentials oils showed citotoxicity against Artemia salina and a DL50 higher than 2000 mg/kg for mice. The analgesic and anti-inflammatory activities of essential oils were exhibit for the doses of 100 and 200 mg/kg.
