Impact of the design of U.S. history textbooks on content acquisition and academic engagement of special education students: an experimental investigation

We used randomized controlled trials to compare the impact of the designs of 2 United States history textbooks on the content acquisition and behavior of 8th-grade students identified for special education services or identified as low achieving. We also investigated whether teachers differed in their use of instructional activities and questioning strategies based on the type of text used. Our findings suggest that students learned more history content, were more actively engaged, and answered more questions correctly when using the experimental textbook. Teachers used different activities depending on which textbook they used, but did not differ in types of questions asked.     

丹尼尔论远程教育基础(下)

该文考查了远程教育的基础,它的发展历史和它赖以发展进化的技术。历史上有两种传统的远程教育:远程课堂教学和函授教学。它们具有不同的教育学特征和成本结构。然而,新一代技术即知识媒体,作为计算机技术、电子通信技术和认知科学汇同结合的产物,正在将远程教育的两大传统结合在一起。知识媒体将通过进一步发展远程教育对大学的革新作出重大贡献。
