Technology educators from Black Hills State University (SD) and Purdue University partner with science educators from the University of Massachusetts at Boston and Stevens Institute of Technology to determine the viability of an engineering concept-based approach to teacher professional development for secondary school science teachers in life science and in physical science. The project refines the conceptual base for engineering at the secondary level learning (previously developed by the PIs) to increase the understanding of engineering concepts by the science teachers. In a pilot test of two weeks of professional development with ten teachers from each discipline, teachers become familiar with engineering concepts and study the process of infusing engineering concepts into science curricula so that they can develop modules in their discipline to be taught during the following in the school year. The following summer the teachers debrief the process and develop additional modules for their discipline. The process is revised and repeated with 22 teachers from each discipline. Teachers are explicitly provided strategies to help them meet the needs of diverse learners. The outputs of this project include: 1) a preliminary framework for secondary level engineering education to be published in both research and practitioner journals; 2) a pilot tested and validated Engineering Concept Assessment; 3) engineering-infused curriculum modules in life and physical science; and 4) a professional development model to prepare science teachers to infuse engineering in their teaching. The project compares student learning when particular concepts in physics and biology are taught through engineering design with learning the same concepts taught an earlier group of students with present reform techniques used in the discipline. The hypothesis is that when teachers and students engage with engineering design activities their understanding of science concepts and inquiry are also enhanced. The research component of the project employs an iterative design with the design of activities followed by development and implementation. An engineering concept assessment is developed and tested to examine teacher learning and to determine how engineering concepts can be infused into the science curricula for life and physical science. Other quantitative and qualitative instruments are developed to assess the teachers? understandings of the engineering concepts and their pedagogical implications. There is increasing emphasis on integrative STEM education. New national and international assessments are developing engineering strands and emphasizing non-routine problem solving. The framework for the Next Generation Science Standards includes engineering as one of four strands. Stand alone engineering course are not likely to be widely used. This project develops engineering infused science units and determines the professional development needed to use them effectively.

来自黑山州立大学（SD）和普渡大学的技术教育工作者与来自马萨诸塞州大学波士顿分校和史蒂文斯理工学院的科学教育工作者合作，以确定基于工程概念的方法对生命科学和物理科学中学科学教师的教师专业发展的可行性。 该项目完善了中学工程学的概念基础（以前由专业研究员开发），以增加科学教师对工程概念的理解。 在为期两周的专业发展试点测试中，每个学科有10名教师，教师熟悉工程概念，并研究将工程概念融入科学课程的过程，以便他们能够在本学科中开发模块，在下一学年中教授。 第二年夏天，教师们听取了这个过程的汇报，并为他们的学科开发了更多的模块。 每个学科的22名教师对这一过程进行了修订和重复。 明确向教师提供战略，以帮助他们满足不同学习者的需求。 该项目的成果包括：1）将在研究和实践期刊上发表的中学工程教育初步框架; 2）经过试点测试和验证的工程概念评估; 3）生命和物理科学中融入工程的课程模块;以及4）准备科学教师在教学中融入工程的专业发展模式。 该项目比较了学生学习时，在物理学和生物学的特定概念，通过工程设计与学习相同的概念教了一组学生与本学科中使用的改革技术的早期。 本研究的假设是，当教师和学生参与工程设计活动时，他们对科学概念和探究的理解也得到了增强。 该项目的研究部分采用迭代设计，先设计活动，然后进行开发和实施。 一个工程概念评估的开发和测试，以检查教师的学习，并确定如何工程概念可以注入到生命科学和物理科学的科学课程。 其他定量和定性的工具来评估教师？工程概念的理解及其教学意义。 人们越来越重视综合STEM教育。 新的国家和国际评估正在发展工程股，并强调非例行问题的解决。 下一代科学标准的框架包括工程作为四个方面之一。 独立的工程课程不太可能被广泛使用。 该项目开发工程注入科学单位，并确定有效使用它们所需的专业发展。
