What Preschool Classroom Experiences Are Associated With Whether Children Improve in Visuomotor Integration?

Research Findings: This study examined the contribution of several class-room experience measures (classroom characteristics, teacher characteristics, and teacher–child interactions) to preschoolers’ improvement in visuomotor integration. Children (N = 467) ranged in age from 3 to 5 years old and were enrolled in 115 classrooms in 5 U.S. states. Children’s visuomotor integration was measured twice (on average 5.2 months apart) using the Beery-Buktenica Developmental Test of Visual-Motor Integration (visuomotor integration subtest). Hierarchical linear models controlling for background characteristics and inhibitory control showed that children improved more in visuomotor integration when they were in classrooms with fewer 3-year-olds, when their teacher had at least a bachelor’s degree, and when teachers demonstrated high quality in their interactions. Practice or Policy: Visuomotor integration, and specifically the ability to copy designs with a writing utensil, is a robust indicator of children’s school readiness and longitudinal achievement. U.S. preschoolers gained more on visuomotor integration in classrooms with fewer 3-year-old children that were taught by a college-educated teacher and when such classrooms provided high-quality organizational and instructional interactions. These results expand the outcomes linked to early childhood education experiences and emphasize the need for well-prepared early childhood teachers who interact with children effectively.     

中介组织:现代高等教育管理的重要一环

在当前深化高等教育管理体制改革的过程中 ,借鉴国外发达国家的经验 ,建立和完善高等教育中介组织 ,应该成为我国高等教育的一个重要问题。随着政府管理职能的转变 ,高等教育中介组织将有一个健康发展的环境。转变观念、赋予中介组织以合法性、提高中介组织的素质、加强对中介组织的理论研究 ,则是当前值得我们关注和思考的问题

Effects of slag fineness on durability of mortars

In recent years, the usages of by-products and wastes in industry have become more important. The importance of the sustainable development is also of increasing. The utilizations of wastes, as mineral admixture or fine aggregate, reduce the consumption of the natural resources and improve the durability of concrete. In this study, the effect of the fineness on the high temperature and sulphate resistances of concrete mortar specimens, produced with ground granulated blast-furnace slag (GBFS) replacing cement, is investigated. The compressive and flexural strength test results for all series related to durability effects, exposing temperature and solutions, exposure times for these durability effects, slag content and fineness are discussed. Conse- quently, the optimum slag contents are determined for producing the sulphate and high temperature resistant mortars.     

The process of supervision in the turkish educational system: purpose, structure, operation

The aim of this study is to provide information on the purposes, structure and operation of the process of supervision in the Turkish educational system. In this paper, the historical development of supervision services in the Turkish educational system, as well as the purposes and principles of educational supervision in Turkey and the structure of supervision in the Turkish educational system are defined. Moreover, the organization of sub-systems of the Ministry of National Education and that of supervision at elementary schools, hiring supervisors, their training, duties and responsibilities as well as working principles are presented. In addition, a detailed analysis of the supervision of institutions and teachers by supervisors is included.
