理解学习空间:概念内涵、本质属性与结构要素     

景玉慧  沈书生 《电化教育研究》2021,42(4):5-11

教学范式向学习范式转型之际,重新设计作为教育变革媒介的学习空间成为重要的研究命题。然而,当前对学习空间尚未形成清晰的认知。文章首先立足学习空间与学习环境交叉混用现状,通过概念辨析得到学习空间是中介物,是学习发生的间接支持条件,学习环境是刺激物,是学习发生的直接支持条件;其次,通过认识发生过程与生物学蛋白质合成过程的类比,得到学习空间具有“居所”与“转运”双重属性;最后,基于双重属性提炼出学习空间的结构要素,“居所”属性锁定的实体场所和虚拟场所,“转运”属性锁定的工具性客体和对象性客体。  相似文献

Innovators and imitators: Organizational reference groups and adoption of organizational routines   总被引：3，自引：0，他引：3

Firms vary greatly in their rates of creating and adopting technological and organizational innovations, in part because of their choice of reference group. We argue that the selection of a reference group is a crucial and neglected source of firm heterogeneity. Comparisons to the average of other firms in a population cause most firms to adopt innovations once they are widely accepted. A distinctive feature of the minority of innovating firms that create innovations or adopt them early is that they compare themselves with, compete with, and try to differ from other innovating firms, whereas the majority of firms compare themselves with, and conform to, a broader group of firms. We elaborate this argument based on the behavioral theory of the firm and institutional theory, and test it on a two-period survey on adoptions of innovative organizational forms in Europe and the US. The analysis shows the predicted differences in the adoption patterns of innovating and imitating firms.  相似文献

Environmental jolts, institutional change, and the creation of entrepreneurial opportunity in the US electric power industry   总被引：1，自引：0，他引：1  

Wesley D Sine  Robert J David 《Research Policy》2003,32(2):185-207

The relationship between institutional change and entrepreneurship is poorly understood. We build the theory in this area by tracing institutional change in the US electric power industry over a 40-year period. Our analysis shows that environmental jolts mobilize actors to reformulate institutions, resulting in increased entrepreneurial opportunity. When the institutional environment is stable, we find that incumbent organizational forms and embedded logics present formidable obstacles to entrepreneurial activity. Environmental jolts, however, catalyze search processes and motivate the evaluation of current institutional logics. Specifically, in the case of the electric power industry, environments of abundance and regulation resulted in homogeneity of organizational structures and strategies, and few entrepreneurial opportunities. Environments marked by scarcity and crisis, however, witnessed heavy scrutiny of existing institutional arrangements that eroded their taken-for-grantedness and symbolic value, resulting in opportunities for entrepreneurial action.  相似文献

Convergence of national science and technology policies: the case of Finland   总被引：4，自引：0，他引：4  

Tarmo Lemola   《Research Policy》2002,31(8-9)

It is a commonly held view that differences in national histories, cultures, political contexts, and the timing of a country’s entry into the industrialization process are reflected as diversity among countries in their goals, priorities, boundaries, directions, ranges, instruments and also in the performance of science and technology policy. This article, which examines development processes of Finnish science and technology policy, concludes that instead of divergence there is such startling convergence of organizational forms and practices. Finland has largely adopted its policy doctrines and instruments from the countries, which from the Finnish perspective, have been considered legitimate and successful.  相似文献
