三网融合将带来什么？

如果把互联网、电信网和广电网做个比喻的话,中国联通广东公司鲁越宁的话别有一番新意,“互联网是新的,草根的、创业的、创新的、引进的,是多种所有制合作的基因,比较复杂多样的;电信网是最老的,因而几乎是完全国有的、传统的、继承的、比较规范的,因而基因比较纯正;广电网更是国有基础上还要代行某些政府职能的、意识形态的、正统的、严肃的、正规的、因而基因更为纯正。”因此,如何把新的、老的,草根的和正统的融合在一起,的确是一个非常大的难题。

Teachers and game-based learning: Improving understanding of how to increase efficacy of adoption

Interest in game-based learning for K-12 is growing. Thus, helping teachers understand how to use these new pedagogies is important. This paper presents a cross-case study of the development of teacher professional development for the River City project, a games-based multi-user virtual environment science curriculum project for middle school children, over three years of its development. Successful professional development required attention to multiple factors including teacher efficacy in using the software, pedagogical issues and school culture. A theoretical model for successful technological implementations is discussed.

Integrating science curricula in the middle school: Utilizing historical perspectives

Abstract

Science curriculum outcomes at the middle school level are typically associated with the decontextualized science found in textbooks and teacher resources. However, the typical middle years classroom with a single teacher is an ideal setting for an integrated approach to learning science in the context of social studies, language arts, art, and other subject areas. In this paper, we describe the first phase of a three‐phase integrated curriculum project. The curriculum uses an historical perspective, narratives, and a student‐centred approach to create materials that integrate the Grade 5 Science weather cluster with the Grade 5 Social Studies unit on the Canadian fur trade. Risk factors that contribute to inadequate science teaching and learning are identified and several protective factors that contribute to teacher efficacy are advanced.

Boys’ and girls’ ICT beliefs: Do teachers matter?

This exploratory study took place in the context of middle school information science in Greece, to examine possible relations between boys’ and girls’: value and efficacy beliefs about computers and information science; perceived parental support; perceived teacher expectations; and perceptions of the nature of information science instruction. The participants of the study were 301 (135 male and 166 female) students who responded to a self-report questionnaire. Regression analysis showed that perceived teacher expectations were positively associated with students’ ability beliefs, perceptions of learning activities as creative and personally meaningful was a significant predictor of students’ interest in computing, and perceived parental support was related to both value and efficacy beliefs. Unlike previous research, the findings of this study did not support the conclusion that boys have more positive ICT self-efficacy and value beliefs than girls. They indicated however, that boys’ and girls’ beliefs are differentially affected by parents, teachers, and school IS instruction.     

Laptops in the K-12 classrooms: Exploring factors impacting instructional use

The purpose of this study was to examine factors affecting teachers’ integration of laptops into classroom instruction. A research-based path model was tested based on data gathered from 379 K-12 school teachers to examine direct and indirect contributions of relevant institutional factors (overall support for school technology, technical support, and professional development) and teacher level factors (teacher readiness and teacher beliefs). The major premise of this study was that the hypothesized path model was powerful enough to explain a substantial amount of variance in teacher readiness (43%), beliefs (51%), and laptop integration (55%). The results suggest that teacher level factors (teacher readiness and teacher beliefs) strongly predict laptop integration, and that overall support for school technology and professional development have strong effects on teacher beliefs and readiness, respectively. All school-level factors also had a significant indirect impact on laptop integration, which is mediated by teacher readiness and beliefs.
