Transforming Teaching through Implementing Inquiry (T2I2)

通过实施探究（T2 I2）转变教学是一个完整的研究和开发项目，探索使用网络基础设施，以显着提高8-12年级工程，技术和设计教育工作者的专业发展（PD）的交付和质量。该项目的目标是研究高度互动的网络基础设施的使用是否增加了目标受众的：1）理解工程设计概念并能够有效地教授他们2）理解如何解决学生的学习需求3）管理，监控，并调整学习环境; 4）使用自我评估以提高教学能力; 5）参与实践社区。这些问题是特别感兴趣的，因为有限的资源准备职前工程和CTE教师，以及缺乏在职PD。PD的内容基于国家研究理事会（NRC）报告审查委员会审查的两个项目的材料和过程：技术教育：中学设计学习”和“高中设计工程”。“通过采用面向对象的通用系统设计（学习对象），网络基础设施被设置为可重复使用，适应性强，可扩展。这些学习对象允许学习体验的定制，由此学习促进者或学习者自己可以基于他们的特定需求来配置系统。 本研究采用混合方法研究教师专业发展的效果。学生的成绩是通过比较每个网站的状态评估在以下领域：课程的技术，工程和设计评估，期末数学评估，期末科学评估。形成性和总结性评价战略为项目的制定和实施提供信息。因此，该项目将推进理论，设计和实践在初中和高中工程，技术和设计为基础的教室。

Transforming Teaching Through Implementing Inquiry (T2I2) is a full research and development project that explores the use of cyberinfrastructure to significantly enhance the delivery and quality of professional development (PD) for grades 8-12 engineering, technology, and design educators. The goal of the project is to study whether the use of highly interactive cyberinfrastructure increases this target audience's: 1) understanding of engineering design concepts and ability to effectively teach them 2) understanding of how to address student learning needs 3) ability to manage, monitor, and adjust the learning environment 4) use of self assessment to enhance teaching ability and 5) engagement in a community of practice. These issues are of particular interest because of the limited resources in place to prepare pre-service engineering and CTE teachers, as well as a lack of in-service PD. The content for the PD is grounded in the materials and processes of two projects reviewed by the National Research Council's (NRC) report review committee: Technology Education: Learning by Design for Middle Schools" and "Engineering by Design for High Schools." By incorporating an object-oriented generic system design (learning objects), the cyberinfrastructure is set to be reusable, adaptable, and scalable. These learning objects allow for customization of the learning experience, whereby learning facilitators or learners themselves can configure the system based on their specific needs. Delivering learning objects in an online framework enables teachers to develop and grow in a network community.A mixed methods approach is used to determine effects of professional development. Student achievement is measured by comparing each site's state assessments in the following areas: the curriculum's technology, engineering, and design assessment, end-of-grade mathematics assessment, and end-of-grade science assessment. Both formative and summative evaluation strategies inform the development and implementation of the project. As such, the project will advance theory, design, and practice in middle and high school engineering, technology and design-based classrooms.
