The Discovery Research K-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering and mathematics (STEM) by preK-12 students and teachers, through research and development of innovative resources, models and tools (RMTs). Projects in the DRK-12 program build on fundamental research in STEM education and prior research and development efforts that provide theoretical and empirical justification for proposed projects. The investigators of this study propose to develop and study two sets of instructional materials for K-2 teacher professional development in mathematics and science that are aligned with the Common Core State Standards in Mathematics (CCSS) and the Next Generation Science Standards (NGSS). They will develop two modules in each subject area and an introductory module that prefaces and integrates the science and mathematics materials. Teachers will be able to review the materials online, watch video of exemplary teaching practice, and then upload their own examples and students' work to be critiqued by other teachers enrolled in professional learning communities as well as expert coaches. New instructional materials aligned with the standards are needed to assist teachers in meeting the challenging instructional practices recommended. To date, scant few resources of this type exist and, given many school districts have limited resources, more cost-effective forms of development such as this must be found. A particular strength of this project is that teachers will be able to engage in the courses online, on an ongoing basis and integrate what they have learned into their daily teaching practice.The investigators propose a program of design research to develop and improve the modules. The central hypothesis is a test of the Teaching Channel model--that the modules and professional learning communities result in significant changes in the quality of instructional practice. Text analytics will be performed on the online discussion to detect changes in group discourse over time. Changes in instructional quality and vision will be measured by observing the videos posted by teachers. Pre-post tests of student work will be performed. The findings of the research will be disseminated through conference presentations, publications, and the Teaching Channel website.

探索研究K-12计划（DRK-12）旨在通过研究和开发创新资源，模型和工具（RMT），显着提高学前班学生和教师的科学，技术，工程和数学（STEM）的学习和教学。DRK-12计划中的项目建立在STEM教育的基础研究和先前的研究和开发工作的基础上，这些研究和开发工作为拟议项目提供了理论和经验依据。本研究的调查人员建议开发和研究两套教材的K-2教师专业发展的数学和科学是符合数学（CCSS）和下一代科学标准（NGSS）的共同核心国家标准。 他们将在每个学科领域开发两个模块，以及一个介绍性模块，介绍并整合科学和数学材料。 教师将能够在线审查材料，观看示范性教学实践的视频，然后上传自己的例子和学生的工作，由专业学习社区的其他教师以及专家教练进行批评。 需要与标准相一致的新教学材料，以协助教师满足所建议的具有挑战性的教学实践。 到目前为止，这类资源很少，鉴于许多学区资源有限，必须找到更具成本效益的发展形式。该项目的一个特别优势是教师将能够在线参与课程，在持续的基础上，并结合他们所学到的到他们的日常教学实践。调查人员提出了一个设计研究计划，以发展和改进模块。中心假设是对教学渠道模型的检验--模块和专业学习社区导致教学实践质量的显著变化。 将对在线讨论进行文本分析，以检测群体话语随时间的变化。 教学质量和视野的变化将通过观察教师发布的视频来衡量。 将进行学生作业的前-后测试。 研究结果将通过会议报告、出版物和教学频道网站传播。
