基于APOS理论的高等数学概念教学模式

高等数学教学中基本概念的教学是基础。基于APOS理论的高等数学概念教学模式分为四个阶段：Action（操作或活动阶段），Process（过程阶段），Object（对象阶段），Scheme（模型阶段）。这种教学模式既注重了数学概念的逻辑结构分析，又重视概念形成过程的思维过程分析，可以帮助学生形成较稳定的数学概念心理图式。

Unpacking the Path‐Dependent Process of Institutional Change for PPPs

In the recent past, several countries and states have begun to use Public‐Private‐Partnerships (PPPs) for infrastructure development and have attempted to create institutional environments that enable PPPs. Providing an enabling environment for PPPs entails a combination of institutional creation and changing existing institutions relating to project procurement. This paper attempts to understand how path‐dependant institutional change takes place in the context of PPPs and their enabling environments, and why different institutional environments evolve differently, using two cases: the implementation of PPPs in the road sector in the Netherlands and in the Indian state of Tamil Nadu. We identify two factors that can be used as predictors of the direction of institutional change: a long‐term orientation towards institutional change and a willingness to learn and modify transitional institutions. Where these factors exist, and thereby provide a goodness of fit, institutional change is likely to occur.
