学习迁移的系统理论:PPEE理论模型的建构和意义

学习是人类社会永恒的主题。为了更好地利用过去的经验，增强学习效果，个人和组织进行学习迁移具有重要意义。学习迁移是指将在以往通过学习或解决问题所获得的经验，用于解决之后所遇到的问题。本文力图建立系统的学习迁移理论，研究人、问题、环境的因素对于学习迁移的影响。本文采用理论推导的研究方法，在前人研究的基础上，提出相应的理论模型。本文运用系统的观点，构建了学习迁移的PPEE理论模型，认为人的因素、问题的因素、人和问题的交互作用、以及环境的调节作用，会共同影响学习迁移的效果。本理论主要从五个方面论述学习迁移的机制。首先，将人的因素按照不同层面划分为后端基本能力、中端心理过程、前端知识结构，讨论了其各自对学习迁移效果的直接影响。其次，将问题的因素划分为形象相似性和抽象相似性，并根据这两个维度构建了四种问题间关系类型，并探究了其与学习迁移效果之间的关系。第三，同时考虑人的因素和问题的因素，研究了二者之间的互动对于学习迁移效果的影响。第四，将环境因素划分为时间紧迫性和空间重要性两个维度，探讨了人和环境，以及问题和环境之间的互动对学习迁移效果的影响。第五，基于系统整体的方面，研究人、问题、环境三者之间的互动对学习迁移效果的交互影响。本文还认为，该模型不仅适用于个人，也同样适用于团队、组织、地区、甚至国家和社会等各个层面，影响各个层面主体的学习迁移。本文最后总结了研究的理论和实践贡献，并提出了未来研究课题。本文对丰富学习理论、特别是学习迁移理论，以及推动教育和管理实践的发展进步具有重要的意义。

幼儿园教师观察能力提升策略——基于课程游戏化背景

江苏省推行课程游戏化项目已四年有余，“观察”在其中扮演重要的推动角色。随着项目的全面开展实施，幼儿园教师的观察能力有了明显变化，但其中仍然存在一些“不够科学”的现象。基于此，教师应养成制定观察计划的习惯，提高获取有用信息的能力以及增强观察记录的实效性，从而深化推进课程游戏化建设。     

日本新订高中历史课程之特点与启示

2018年3月,日本发布新的《高等学校学习指导要领》。这是日本自第二次世界大战后70多年来,对高中课程最大规模的一次修订,体现了日本高中教育发展的新趋势,标志着日本从此告别“宽松教育”而走向“生存能力”教育。由“历史综合”“日本史探究”“世界史探究”组成的新高中历史课程,立足“人”的发展,构建了“必修+选修、通史+专题”的课程体系,课程内容更加突出本国史与世界史的联系,课程学习倡导“主题+探究”的学习方式。日本高中历史课程的内容设置及特点启示我们,高中历史课程编制应加强中国史与世界史的横向关联,课程内容应体现探究性学习要求。     

COWORDS: a probabilistic model for multiple word clouds

Word clouds constitute one of the most popular statistical tools for the visual analysis of text documents because they provide users with a quick and intuitive understanding of the content. Despite their popularity for visualizing single documents, word clouds are not appropriate to compare different text documents. Independently generating word clouds for each document leads to configurations where the same word is typically located in widely different positions. This makes it very difficult to compare two or more word clouds. This paper introduces COWORDS, a new stochastic algorithm to create multiple word clouds, including one for each document. The shared words in multiple documents are placed in the same position in all clouds. Similar documents produce similar and compact clouds, making it easier to simultaneously compare and interpret several word clouds. The algorithm is based on a probability distribution in which the most probable configurations are those with a desirable visual aspect, such as a low value for the total distance between the words in all clouds. The algorithm output is a set of word clouds that are randomly selected from this probability distribution. The selection procedure uses a Markov chain Monte Carlo simulation method. We present several examples that illustrate the performance and visual results that can be obtained by our algorithm.     

从教师专业实践能力发展反观高校与幼儿园的双向融合

当前，打通高校教师理论研究与基层一线教师专业发展瓶颈是总体提升我国教育质量的高效之举，教育的实践性本质也决定了高校教师的理论研究与一线教师的教育实践必须坚持双向融合的道路。实现校园双向融合既要积极构建教师发展共同体，还要积极探索有深度和广度的教研机制，并搭建开放、多元、创新的资源平台。     

我国农业传统文化与后现代农业发展的相关思考

现代农业的发展是以功利性为特征的,受经济目标的逐利影响,正逐渐步入生态困境。后现代农业发展阶段将出现农业生态观的原始回归,这将为我国农业传统文化功能的发挥创造机遇。我国后现代农业发展阶段应重视传统农业文化的诉求,挖掘本土农业文化资源,加强对外引文化的审视,提高农业自我创新能力。     

Family Background and the Process of Ability Formation*

This paper takes a sociometric approach to the process of skills formation in children as they mature into adults. Honda suggests that meaningful communication with family as a child is the determining factor that raises those abilities (ability β ¹ ) that fall outside of scholastic aptitude – motivation, personal relations skills, personality, and emotions. Along with considering the results of Honda's thesis, I have constructed an operating hypothetic model that includes two additional factors: the financial state of the family during childhood, and the transition of the communication target from within the family to a target outside the family. The data for this investigation were then verified. From the results, the direct effect of the observed family communication, when isolated from other influencing variables in the formation of abilities β, is not as decisive a factor as Honda emphasized. It was clear that the financial status of the family played a role, as did the indirect results of the intermediary shift from communication within the family to outside the family (the process of children becoming socially independent). The results of this analysis show that we should not necessarily be looking for the decisive factors of abilities β within the family; if anything, it reflects the existence of a formative route for abilities β that capitalizes on the resources outside the family. Based on the above, the results also show the potential for the introduction of social intervention to address the disparity and inequality in skills formation, and the possible anticipation of more rationality in the overblown discourse surrounding the role of the family in facilitating educational ability.
