The Potential of Systems Thinking in Teacher Reform as Theorized for the Teaching Brain Framework

The teaching brain is a dynamic system that is in constant interaction with the learning brain. If we fail to explore the teaching brain we will continue to design educational reform policies that ignore the most important lens in the classroom: the teachers'. Master teachers recognize their perspective and leverage their teaching brains to embody a systems thinking view of their practice. If all teachers were taught how to recognize themselves as self‐created, organized systems existing within the larger teaching–learning interaction, they would understand how their context and intentions affect the teacher–student interaction. Education reform must acknowledge and understand more about the teaching brain, how master teachers practice systems thinking and the mutually interacting brains of teacher and student if we hope to truly improve how we educate children.

A Model for Thinking About the Evaluation of Training

A model for thinking about training evaluation is proposed. The model consists of context and process factors on the one hand, and outcome factors on the other. Among context and process factors are basis of training, purpose of training, unit of productivity, data sources, kind of training, who is trained, and costs of training. Outcome factors include employee, customer, and corporate aspects. Assumptions of the model include a) that both corporatist and humanistic conceptions of training are to be viewed as valid, and b) that the term training is constrictive and probably should be replaced by the term education, which is more elastic. An impetus for the model is that work and workplaces are changing. How knowledge, skills, and orientations toward evaluation are utilized must be viewed somewhat more expansively than might have been appropriate under work conditions in “Tayloristic” times.

中国传统文化思维框架论纲

时间观、空间观、主体观、以及因缘观等基本观念构成了时空共振、天人合一的大一统宇宙图式，这就是中华传统文化的思维框架。这个框架不仅限定了人们思考和想象的方式、范围，而且预设了人们行为的准则和依据，即以王、道为核心的价值系统——包括中央权威(王)、等级秩序(礼)、合谐(乐)、中庸(道)等核心价值，审美的生活态度，注重实用的生存原则，以及怀方行圆、以静制动、知微待时、安份守位等人生策略；在这个框架之内，在认识与实践领域，则形成了中华特色的社会观、历史观、人性论、方法论、知行观等纲纽性观念，作为思想家们构筑其理论体系的基石。
