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

该项目由发现研究K-12(DRK-12)计划资助，该计划旨在通过研究和开发创新资源、模型和工具，显著提高K-12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努力的基础上，这些研究和开发工作为拟议的项目提供了理论和经验证明。该项目与俄勒冈州公共广播公司合作，将通过重建现有的生物科学课程研究(BSCS)中学科学生命科学单元，开发一个基于在线课程的在线课程，并得到教师专业发展(PD)计划的支持。这些材料将包括战略性集成的多媒体元素，包括动画、互动学习体验和为学生提供的增强阅读，以及为教师提供的课堂视频，这些视频将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完全数字化的下一代科学标准(NGSS)资源的典范，创造一个与NGSS一致的学习环境，将学科核心思想与科学和工程实践以及交叉概念结合在一起。利用数字环境的强大资源，该项目将激励和激励学习者，并支持教师，因为只有媒体丰富的环境才能做到这一点。该项目将开发和研究项目创新，将学生的数字教学材料与在线教师PD结合起来，使用经过验证的课程分析框架。虽然以前的研究已经证明了课程分析PD和课程要素独立存在的有效性，但很少有人研究它们联合起来改变教与学的能力。该项目将通过在准实验研究中纳入一系列复杂的多组成部分评估活动，包括基于课堂的评估，将该项目的研究和开发结合在一起。评估活动将采用以证据为中心的设计过程，其中将包括仔细选择和制定评估任务、评分准则和基于表现期望(PE)的评分标准，以及获得关于学生熟练掌握这些PE的证据的最佳方法。这项由SRI国际进行的研究将使用多个组成部分的任务，这些任务将支持关于学生学习的推断，并促进对如何评估NGSS学习的理解。项目研究和资源，将包括一个数字、中学生命科学单元、教师PD和在线数字资源，以及相关评估工具，将广泛传播给决策者、研究人员和实践者。

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.
