Promoting early literacy through the professional development of preschool teachers

The purpose of this study was to examine the effect of a professional learning program on the emergent literacy skills of preschool children. Building Blocks for Literacy^® is a program consisting of training supported by mentoring designed to teach early childcare providers how to promote the development of early literacy skills. A previous investigation found positive effects of the program on the pre-literacy skills of children in Vermont. The current study extended their work by replicating the training for Head Start teachers (n?=?27) in another state. Teachers were divided into three groups. One group received the training and live mentoring; a second group received training and distance mentoring; and a third group of teachers served as controls. The results indicate that children (n?=?97) served by teachers who received the training (n?=?18) made higher gains on a measure of early literacy skills than those children (n?=?36) served by control teachers. The gains made by children in the treatment groups were consistent for teachers who received either live or distance mentoring. Implications for practice are discussed.

李二曲教育思想刍议

清初大儒李二曲继承和发扬了传统儒家注重“为己之学”的教育智慧,通过对“过”、“悔”“新”的重新诠释和改造,创造性地提出了“悔过自新”说,深化了儒家关于自我教育的思想。该学说以性本善和人皆有“过”为自我教育的起点,以转念和慎独为自我教育的方法,以实现个我之“新”和社会之“新”为自我教育的目标,将儒家教育思想中的自我教育原则推向极致,对发展现代教育不无启发意义。     

Social network data to alleviate cold-start in recommender system: A systematic review

Recommender Systems are currently highly relevant for helping users deal with the information overload they suffer from the large volume of data on the web, and automatically suggest the most appropriate items that meet users needs. However, in cases in which a user is new to Recommender System, the system cannot recommend items that are relevant to her/him because of lack of previous information about the user and/or the user-item rating history that helps to determine the users preferences. This problem is known as cold-start, which remains open because it does not have a final solution. Social networks have been employed as a good source of information to determine users preferences to mitigate the cold-start problem. This paper presents the results of a Systematic Literature Review on Collaborative Filtering-based Recommender System that uses social network data to mitigate the cold-start problem. This Systematic Literature Review compiled the papers published between 2011–2017, to select the most recent studies in the area. Each selected paper was evaluated and classified according to the depth which social networks used to mitigate the cold-start problem. The final results show that there are several publications that use the information of the social networks within the Recommender System; however, few research papers currently use this data to mitigate the cold-start problem.

《红楼梦》中贾雨村艺术形象问题综论

众多研究者对贾雨村的艺术形象缺乏全面系统的认识。《红楼梦》所反映的主要是清朝乾隆时期的上流社会生活,贾雨村处在相对稳定的康乾盛世时期,其时经世致用思想得到大力提倡,私欲的合理性得到肯定,“人欲之各得”的社会价值取向得到承认。贾雨村不可能脱离这个时代的社会价值取向而独立存在,因此,应将他还原至当时的社会背景及其主流价值观念中分析其艺术形象。贾雨村对人生报有积极态度并通过主流价值观念认可的努力方式博取功名,才干优长且思想卓尔超群,隐忍宦海并富有谋略。之所以众多研究者没有看到贾雨村形象的积极性,主要是因为研究者与艺术形象本身所处社会本质的不同和研究者未能摆脱悲剧情节对自己的情感惯性影响。     

2种不同起跑动作的生物力学实验研究

采用测力台与肌电同步的方法对 4名一级短跑运动员的蹲踞式与站立式起跑动作进行了运动生物力学分析。研究结果 :蹲踞式起跑中水平支撑反作用力明显大于站立式起跑时水平支撑反作用力 ;蹲踞式起跑和站立式起跑中的肌肉活动顺序即肌肉用力顺序各不相同 ;蹲踞式起跑和站立式起跑中肌肉的肌电活动时间和幅度 ,即肌肉用力程度各不相同 ,在蹲踞式起跑中右股直肌用力程度最大 ,而站立式起跑中右腓肠肌用力最大 ;股直肌和腓肠肌是这 2种起跑姿势的主要用力肌群
