Researching the Wireless High School: Effects on Science Teaching and Implications for Professional Development

本研究调查无线环境对高中科学的影响，采用有目的的高实现者学校抽样。将对五所学校进行调查，并以多种形式收集每所学校的大量数据。该项目使用深入的案例研究来检查可能影响无线高中科学课堂科学教学实践的环境因素（例如技术实施计划、学校文化、教师专业发展的程度和类型以及教师背景）和关键互动。这项研究将产生一个基于证据和理论基础的专业发展模型，为专业开发人员、管理人员、政策制定者和教师提供信息。这项研究可协助专业服务提供者制订专业发展模式，协助学校在初始安装、部署和培训方面作出合理选择；为了帮助教师方便地访问数字资源，选择能够促进其教学目标的资源，根据数字资源提供的丰富科学理解和内容的附加价值，有效地评估数字资源的质量，制定教学策略，使学生能够与这些资源互动，从而丰富课堂话语和互动，并制定有效使用数字资源的策略，以便能够评估学生的作业。

This research study investigates the impact of the wireless environment on high school science using a purposeful sampling of schools with high implementers. Five schools will be examined and extensive data in multiple forms will be collected on each. The project uses in-depth case studies to examine context factors (e.g. technology implementation plans, school culture, extent and type of teacher professional development and teacher background) and critical interactions that may influence science instructional practice in wireless high school science classrooms. The study will result in an evidence-based and theoretically-grounded professional development model that will inform professional developers, administrators, policy-makers and teachers. The research will enable the PIs to develop a professional development model to help schools make reasonable choices about initial installation, deployment and training; and to help teachers to access digital resources with ease, select resources that will further their teaching goals, effectively evaluate the quality of a digital resource in terms of the additional value that it affords to enrich science understanding and content, develop pedagogical strategies to enable student interactivity with such resources to enrich classroom discourse and interaction, and develop strategies to use digital resources effectively in being able to assess student work.
