探究导向的科学课程演示型课件结构和内容设计

科学课程的探究教学要重视演示型课件的结构和内容设计,能充分发挥其优化课堂学习环境的作用,引导参与和思考。设计合理的课件结构,以引导课堂的探究活动,促进学生了解知识结构。对来自教科书和教师的教案的内容进行选择、改造和加工,转变为能够发挥演示课件优势的探究内容。恰当利用Powerpoint的页内动画,使静态内容动态化,形象地展示逻辑顺序、变化过程和转化关系等,引导观察和思考。     

关于构建和谐文化的思考

构建和谐文化是建设和谐社会的一项基础性工程。和谐文化,是一种融价值观念、行为方式、价值取向、价值评价为一体的价值观念体系。中国传统文化中的和谐思想、西方对中国传统文化的了解和认同以及中国社会主义和谐社会的伟大实践构成了和谐文化的传统文化渊源和资源、构建和谐文化的现实条件和现实需要。要通过构建新的和谐文化体系、继承和发扬传统文化精华和批判地吸收西方文化的优秀成果、大力发展文化事业和文化产业来构建和谐文化。

试论洪颐煊《读书丛录》的历史考据

洪颐煊是清代嘉、道间的一位重要学者,其治学重文献重考据,在经学、史学以及诸子学等方面成就卓著。本文以其考据学代表性著作《读书丛录》为中心,深入剖析其历史考据,发现其考证内容全面广泛,能够综合运用比较考证法、求源考证法、推理考证法及存疑考证法等考证方法,鲜明地反映出乾嘉考据学家历史考据的典型特点。     

Designating reader perspective to increase comprehension and interest

In three experiments we examined whether reader perspective on a long expository text could be manipulated such that increased text interest and enhancement of two comprehension outcomes would result. In Experiment 1 we verified the viability of a new text for experimental purposes. We then assigned readers a perspective before reading in Experiment 2 and after reading in Experiment 3. One primary research question addressed whether interest in a long expository text could be manipulated by assigning readers a perspective. We considered this to be an examination of purpose-driven interest ( Schraw & Dennison, 1994). As hypothesized, participants rated text segments as more interesting when the segments corresponded to their assigned perspective. In support of our second hypothesis, that recall would increase as a function of reader perspective, low to medium effects were found for both total number and depth of ideas recalled. We discuss implications of this work for understanding of the role of relevance in increasing recall. Implications for practice and future research are also discussed.

Critical features of professional development programs: Comparing content focus and impact of two large-scale programs

By comparing two large-scale professional development programs' content and impact on student achievement, we contribute to research on critical features of high quality professional development, especially content focus. Even though the programs are conducted in the same context and are highly similar if characterized according to established research frameworks, our results suggest that they differ in their impact on student achievement. We therefore develop an analytical framework that allow us to characterize the programs’ content and delivery in detail. Through this approach, we identify important differences between the programs that provide explanatory value in discussing reasons for their differing impacts.     

CloudChain: A novel distribution model for digital products based on supply chain principles

Cloud computing is a popular outsourcing solution for organizations to support the information management during the life cycle of digital information goods. However, outsourcing management with a public provider results in a lack of control over digital products, which could produce incidents such as data unavailability during service outages, violations of confidentiality and/or legal issues. This paper presents a novel distribution model of digital products inspired by lean supply chain principles called CloudChain, which has been designed to support the information management during digital product lifecycle. This model enables connected networks of customers, partners and organizations to conduct the stages of digital product lifecycle as value chains. Virtual distribution channels are created over cloud resources for applications of organizations to deliver digital products to applications of partners through a seamless information flow. A configurable packing and logistic service was developed to ensure confidentiality and privacy in the product delivery by using encrypted packs. A chain management architecture enables organizations to keep tighter control over their value chains, distribution channels and digital products. CloudChain software instances were integrated to an information management system of a space agency. In an experimental evaluation CloudChain prototype was evaluated in a private cloud where the feasibility of applying supply chain principles to the delivery of digital products in terms of efficiency, flexibility and security was revealed.
