A Longitudinal Study of Physics Students’ Conceptions of Force in Pre-service Training for High School Teachers     

RICARDO TRUMPER 《欧洲师范教育杂志》1999,22(2-3):247-258

Do physics students in pre-service training to be high-school teachers hold the accepted scientific views that will eventually allow them to plan and implement instructional strategies, which, in turn, will lead their future students to achieve a scientific concept of feree? The results of a longitudinal study dealing with this issue will be discussed in this paper. The most important findings of this study can be summarised as follows. Physics students in pre-service training for high school teachers: (1) mostly do not succeed in abandoning their Aristotelian ‘impetus’ misconception; (2) have difficulties in recognising reaction as a force; (3) are rather ambivalent when referring to the necessity of the forces to be balanced in static situations; (4) hold, to a great extent, the concept that an initial force exerted on an object keeps it going and gradually lessens--the ‘fading-away’ concept; (5) hold, to a great extent, the concept that a force (inertia), resisting a push, acts on moving objects; (6) tend to return in 4th year in college to intuitive views of force, rather than holding the accepted scientific concept.  相似文献   

Education,Equality and Social Cohesion: A distributional approach     

ANDY GREEN  JOHN PRESTON  RICARDO SABATES 《Compare》2003,33(4):453-470

Promoting social cohesion through education has re-emerged as an important policy objective in many countries during the past decade. But there is little clarity in policy discussions about what social cohesion means and how education may affect it. In this article we distinguish between social capital and societal cohesion and argue that education acts in differential ways on each. Using comparative, cross-country analysis, we develop a 'distributional model' which shows the relationship between equality of educational outcomes and various measures of social cohesion. In the final part of the article we discuss theories explaining the cross-country trends and variations in educational inequality and social inheritance in education, and argue that education system characteristics, such as degrees of 'comprehensiveness' in secondary schooling, may be an important factor in both. We conclude by arguing that policies to increase social cohesion through education must pay more attention to the reduction of educational equality than they currently do.  相似文献
