CAREER: Scaffolding Engineering Design to Develop Integrated STEM Understanding with WISEngineering

六个课程项目的发展将基于共同核心数学标准的数学与下一代科学标准的科学概念相结合，并结合工程设计教学法，这是弗吉尼亚大学DRK-12 CAREER项目的重点。以知识整合的视角研究学习科学，帮助学生建立并保持规范性和相关思想与现有知识结构之间的联系；开发WiseEngineering学习环境，这是一个在线学习管理系统，为工程设计项目搭建脚手架。WiseEngineering为学生和教师在初中和高中环境中进行工程设计项目提供支持。使学习者能够观察和实验现象的动态虚拟化与知识集成模式相结合，为学生构建了一个技术丰富的学习环境。研究的重点是在这些技术增强的环境中，元认知，即自我认识和自我调节与学习的相互作用方式。嵌入式评估和学生对关键科学和数学结构的前后测试提供了学生理解发展的证据。一个检查知识整合的题目被用来检查学生理解多个概念在给定环境中如何相互作用的程度。混合方法研究设计将考察中学数学和科学课程的学生和教师如何发展对STEM基本原则的理解。该奖项的首席研究员通过将她对工程设计和技术支持的学习环境的研究与她所教授的职前中学教育方法课程联系起来，将研究和教育结合在一起。此外，她还将研究成果融入到她担任讲师的教学技术研究生课程中。工程设计是下一代科学标准的一个关键领域，它需要额外的课程材料开发和研究学生如何将数学和科学的概念整合到这些工程实践中。技术丰富的学习环境，WISEngineering，提供了研究学生工程设计原则如何随着时间的推移而演变的背景。学生有机会对彼此的工作提出批评，这为检验关键的元认知原则提供了环境。课堂观察和教师访谈为研究技术丰富的工程设计学习环境如何为教师和学生整合STEM知识提供了机会。

The development of six curricular projects that integrate mathematics based on the Common Core Mathematics Standards with science concepts from the Next Generation Science Standards combined with an engineering design pedagogy is the focus of this DRK-12 CAREER project from the University of Virginia. Research on the learning sciences with a focus on a knowledge integration perspective of helping students build and retain connections among normative and relevant ideas and existing knowledge structures the development of the WiseEngineering learning environment, an online learning management system that scaffolds engineering design projects. WiseEngineering provides support for students and teachers to conduct engineering design projects in middle and high school settings. Dynamic virtualizations that enable learners to observe and experiment with phenomena are combined with knowledge integration patterns to structure a technology rich learning environments for students. The research focuses on the ways in which metacognition, namely self-knowledge and self-regulation interact with learning in these technology-enhanced environments.Embedded assessments and student pre and post-testing of key science and mathematics constructs provide evidence of the development of student understanding.A rubric that examines knowledge integration is used to examine the extent wo which students understand how multiple concepts interact in a given context. A mixed-methods research design will examines how students and teachers in middle school mathematics and science courses develop understanding of the underlying principles in STEM. The PI of this award has integrated research and education in this proposal by connecting her research on engineering design and technology-enabled learning environments with the preservice secondary education methods course that she teachs. In addition, she has folded the research into the instructional technology graduate courses of which she is the instructor.Engineering design is a key area of the Next Generation Science Standards that requires additional curricular materials development and research on how students integrate concepts across mathematics and science to engage in these engineering practices. The technology-rich learning environment, WISEngineering, provides the context to examine how student engineering design principles evolve over time. The opportunitiy for students to provide critiques of each others' work provides the context in which to examine crucial metacognitive principles. Classroom observations and teacher interviews provides the opportunity to examine how the technology-rich engineering design learning environment integrates STEM knowledge for teachers as well as students.
