Montessori's mediation of meaning: a social semiotic perspective
The distinctive objects designed by Dr Maria Montessori as the centrepiece of her approach to pedagogy are the topic of this study. The Montessori approach to pedagogy, celebrating its centenary in 2007, continues to be used in classrooms throughout the world. Despite such widespread and enduring use, there has been little analysis of the Montessori objects to evaluate or understand their pedagogic impact. This study begins by outlining the provenance of the Montessori objects, reaching the conclusion that the tendency to interpret them from the perspective of the progressive education movement of the early twentieth century fails to provide insights into the developmental potential embodied in the objects. In order to appreciate that potential more fully, the study explores the design of the objects, specifically, the way in which the semiotic qualities embodied in their design orient children to the meanings of educational knowledge. A meta-analytic framework comprising three components is used to analyse the semiotic potential of the Montessori objects as educational artefacts. First, Vygotskyâs model of development is used to analyse the objects as external mediational means and to recognise the objects as complexes of signs materialising educational knowledge. In order to understand how the objects capture, in the form of concrete analogues, the linguistic meanings which construe educational knowledge, systemic functional linguistics, the second component of the framework, is used to achieve a rich and detailed social semiotic analysis of these relations, in particular, material and linguistic representations of abstract educational meanings. Finally, the pedagogic device, a central feature of Bernsteinâs sociology of pedagogy, is used to analyse how the Montessori objects re-contextualise educational knowledge as developmental pedagogy. Particular attention is paid to the Montessori literacy pedagogy, in which the study of grammar plays a central role. The study reveals a central design principle which distinguishes the Montessori objects. This principle is the redundant representation of educational knowledge across multiple semiotic modes. Each representation holds constant the underlying meaning relations which construe quanta of educational knowledge, giving children the freedom to engage with this knowledge playfully, independently and successfully. The conclusion drawn from this study is that the design of the Montessori objects represents valuable educational potential which deserves continued investigation, as well as wider recognition and application. To initiate this process, the findings in this study may provide insights which can be used to develop tools for evaluating and enhancing the implementation of Montessori pedagogy in Montessori schools. The findings may also be used to adapt Montessori design principles for the benefit of educators working in non-Montessori contexts, in particular, those educators concerned with developing pedagogies which promote equitable access to educational knowledge
Role of acetylcholine and calcium ions in three vascular contraction models: Angiotensin II, phenylephrine and caffeine
Imidazole-induced contractility of vascular smooth muscle cells in the presence of U-73122, ODQ, indomethacin and 7-nitroindazole
The aim of the study was to assess the impact of modulating factors on vascular smooth muscle cells reactivity. Vascular resistance was induced by the administration of increasing concentrations of imidazole. The experiments were performed on isolated and perfused tail artery of Wistar rats (weight 250 g â 350 g). Rats were been narcotized by urethane (intraperitoneal injection) at a dose of 120 mg/kg, stunned and then sacrificed by cervical dislocation. In the following investigation classical pharmacometric methods were used. Relationships between concentration-response curves (CRCs) for imidazole observed in the presence of ODQ [(1H-(1,2,4)oxadiazolo-[4,3-a]quinoxalin-1-one)], 7-nitroindazole and indomethacin were analyzed. Imidazole-induced contractility of vascular smooth muscle cells was independent from alpha-adrenergic receptors and PLC activity. Reactivity of VSMCsinduced by imidazole, was significantly changed in the presence of ODQ and 7-nitroindazole
