Three-Dimensional Teaching and Learning: Rebuilding and Researching an Online Middle School Curriculum

该项目由Discovery Research K-12（DRK-12）计划资助，旨在通过研究和开发创新资源，模型和工具，显着提高PreK-12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。该项目与俄勒冈州公共广播公司合作，将通过重建生物科学课程研究（BSCS）中学科学的现有生命科学单元，开发一个由教师专业发展（PD）计划支持的在线基于生物科学的课程。这些材料将包括策略性整合的多媒体元素，包括动画、互动学习体验和学生强化阅读，以及教师课堂录像，帮助所有用户更深入地了解三维学习。该项目旨在成为教师和学生的完全数字化下一代科学标准（NGSS）对齐资源的典范，创造一个NGSS对齐的学习环境，将学科核心思想与科学和工程实践以及交叉概念相结合。 利用数字环境的强大功能，该项目将激励和激励学习者，并支持教师，因为只有一个媒体丰富的环境可以做。该项目将开发和研究项目创新，结合数字教学材料的学生和在线教师PD使用一个成熟的经验教训分析框架。虽然先前的研究已经证明了课程分析PD和课程元素独立的功效，但很少有人调查它们的联合能力，以改变教学和学习。该项目将把本项目的研究和开发工作结合起来，在一项准实验性研究中纳入一系列复杂的多组成部分评估活动，包括课堂评估。评估活动将使用以证据为中心的设计过程进行设计，该过程将涉及评估任务的仔细选择和开发，评分规则和基于绩效期望（PE）的评分标准以及获取有关学生熟练程度的证据的最佳方法。这项由SRI International开展的研究将使用多成分任务，这些任务将支持对学生学习的推断，并促进对如何评估NGSS学习的理解。项目研究和资源，这将包括一个数字化的，中学生命科学单位，教师PD和在线数字资源，以及相关的评估工具，这将被广泛传播给政策制定者，研究人员和从业人员。

This project was funded by the Discovery Research K-12 (DRK-12) program that 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. 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 project, in collaboration with Oregon Public Broadcasting, will develop an online curriculum-based supported by a teacher professional development (PD) program by rebuilding an existing life science unit of Biological Sciences Curriculum Study (BSCS) Middle School Science. The materials will include strategically integrated multimedia elements including animations, interactive learning experiences, and enhanced readings for students, as well as classroom videos for teachers that will help all users gain a deeper understanding of three-dimensional learning. The project is designed to be an exemplar of fully digital Next Generation Science Standards (NGSS) aligned resources for teachers and students, creating an NGSS-aligned learning environment combining disciplinary core ideas with science and engineering practices and cross-cutting concepts. Using the powerful affordances of a digital environment, the project will invigorate and inspire learners and support teachers as only a media-rich environment can do.The project will develop and research the project innovation, the combination of digital instructional materials for students and online teacher PD using a proven lesson-analysis framework. Although prior research has demonstrated the efficacy of the lesson analysis PD and curriculum elements independently, there has been little investigation of their joint ability to transform teaching and learning. The project will merge research and development in this project by incorporating a complex array of multi-component assessment activities, including classroom-based assessments, in a quasi-experimental study. Assessment activities will be designed using an evidence-centered design process that will involve the careful selection and development of assessment tasks, scoring rubrics, and criteria for scoring based on the performance expectations (PEs) and the best ways to elicit evidence about student proficiency with those PEs. The research, carried out by SRI International, will use multi-component tasks that will support inferences about student learning and advance understanding of how to assess NGSS learning. Project research and resources, which will include a digital, middle school life sciences unit, teacher PD and online digital resources, and related assessment tools, which will be widely disseminated to policy makers, researchers, and practitioners.
