Abstract

This paper scrutinises the educational knowledge requirements of craft, technical, and reflective professional conceptions of teaching, as recently outlined by Winch, Oancea, and Orchard. Drawing on Bernsteinian sociology of knowledge we identify the different requirements each conception makes of educational knowledge, and how it is envisaged that this knowledge will be used in educational practice. While craft conceptions dismiss the value of educational knowledge per se, they nevertheless value other forms of disciplined knowledge. Arguing that technical conceptions of teaching may be either narrowly instrumental or autonomous, we suggest that an advanced technical knowledge base requires a disciplinary aspect, while knowledge for purely instrumental purposes offers a reductive view of educational practice. Moreover, the varying notions of reflection suggested by reflective professional conceptions require certain forms of engagement with educational knowledge, which are challenged by contemporary reforms in teacher education globally. It is suggested that there are often interdependencies between forms of educational knowledge and conceptions of teaching, with potential implications for the trajectories of educational reforms. The argument is briefly illustrated with reference to the national contexts of Germany, England, and Finland.  相似文献

Sap flow and environmental conditions were monitored at two Eucalyptus (Eucalyptus urophylla S.T.Blake)plantations at Hetou and Jijia, located in Leizhou, Zhanjiang, Guangdong Province. It was found that daily sap flux density (SFD) of Eucalyptus was closely related to daily atmospheric vapor pressure deficit (VPD) (R2=0.76, P=0.01 at Hetou and R2=0.7021, P=0.01 at Jijia) at both sites. No significant relationship existed between daily SFD and mean daily air temperature at both sites. Daily SFD varied with wind speed Y=-17585X3 15147X2-1250.7X 2278.4 (R2=0.68; P=0.01) at Hetou and Y=-101.67X3-1.65X2-376.4X 1914.8 (R2=0.40, P=0.05) at Jijia, where Ywas daily SFD, Xwas daily wind speed.Experimental observations yielded the following data: (1) the critical lower and upper daily VPD threshold were 0 and 2 kPa,slightly lower under high relative humidity (>80%) compared with those at the Jijia site; (3) The upper and lower threshold  相似文献

Although measures of student ratings of instruction have been developed and examined empirically, students' attitudes about the utility of these ratings have yet to be meaningfully quantified. Using survey responses from 1229 students at a major Canadian university, we developed a psychometrically sound measure of the usefulness of student ratings. A principal components analysis with oblique rotation was conducted and three factors (Instructor characteristics, Course characteristics and Instructor's relative ranking) were obtained that explained 64% of the variance in six iterations. The usefulness of these three types of ratings information differs according to several student and course characteristics. The present results provide evidence for both reliability and validity of the instrument as an indicator of the utility of teaching evaluation for students.  相似文献

This article addresses the issue of promoting spirituality as a dimension of pastoral care in schools. The everyday practice of caring and giving may leave carers tired, depleted of spiritual sustenance, and without practices that nurture their spirituality. This article proposes that spirituality is an essential element of pastoral care, and that it can be promoted through examination of one's sense of vocation, bodywork, journal writing and nurturing soul friends.  相似文献
