Research on Gender and Education in the Nordic Countries

Sex has for many years been an important independent variable in educational research, but the serious theoretical discussion of the variable as a dependent variable belongs mostly to the last three decades. A need for a conceptual reorientation has emerged which, for one thing, resulted in the replacement of the concept sex by the concept gender. The article in this section presents and discusses the necessity and the development of this theoretical reorientation in the Nordic countries, which has attracted many researchers and instigated inventive projects. In addition the article gives an overview of Nordic empirical gender research in or related to education: first the studies that opened up the field, then the development that followed. This presentation focuses on different subareas, such as studies of gender and ability, learning and achievement, studies of gender aspects of classroom interaction, studies of single‐sex learning arrangements, action research studies in order to expand the interpersonal and emotional skills repertoire of boys and girls, studies of gender identity. Although differences between the Nordic countries are clear, similarity is the dominant trait. At the end the article comments on recent viewpoints on the likely development of gender policy and outlines basic educational questions within the Nordic educational systems.     

Class and gender: Role model considerations and liberations in advanced capitalism

Conclusion In this paper, I have presented a model with very few nuances. My object has been to explore the most typical differences between the social classes and, therefore, I have not commented upon the situation of the lower-middle classes; nor have I given much attention to boys in bourgeois categories. My reason for this is that this special category has very often been the focus of socialization research. Rather I have tried to throw some light upon the socialization of working-class girls, where the concept of familism and of solidarity has been important in my analysis.However, the insights and thought patterns of boys and men in bourgeois categories must, in the same way as those of other social groups, be understood as a consequence of capitalism as a social system — and also be understood within a dialectical frame of reference. In other words, while boys in bourgeois categories are socialized in a way which often makes it possible for them to gain the most sought-after positions in society, they have to suffer certain disadvantages that may be costly for themselves as individuals and for society as a whole.My intention has been to discuss some relationships between socialization and the societal model of production. In a capitalist society, there is a need for some boys to be socialized into the elite and for some girls to be socialized into the reserve army of workers. The cause of women's liberation (as well as men's liberation) may be served in many ways and on many different levels. To me it seems especially important to understand the underlying societal forces that shape the roles of working-class girls and women.
