Grand Challenges for Engineering Focused RET with Stratified Teams

北卡罗莱纳州立大学（NCSU）工程和计算机科学网站的教师研究经验（RET）将重点了解分层团队在K-12学习环境中对教师专业发展和学生最终学习的作用。先前对工程专业本科生、研究生和教师组队的研究显示，每个参与者都有二元效应。除了RET网站的传统产品（包括课堂活动和与前沿研究相关的技术，可用于K-12课堂）之外，该RET还将告知有关K-12学校和大学之间合作关系的知识体系。该项目研究将列举对团队六个不同组成部分的影响的类型和深度：K-12教师、职前教师、社区学院教师、本科工程专业学生、工程专业研究生和大学教师。该项目是NCSU工程学院和北卡罗来纳大学夏洛特分校（UNCC）的合作项目。该项目将在三年内针对达勒姆和夏洛特-梅克伦堡县公立学校的36名在职教师，以及NCSU和UNCC教育学院的职前教师。一个由一名K-12教师、一名社区大学STEM教师、一名职前教师和一名工程本科生组成的团队将在一名合作的工程教师的实验室参加为期六周的暑期密集研究体验。研究课题将集中在工程大挑战的四个子领域之一：可持续性（太阳能）、健康（生物力学）、安全（计算机网络安全）和生活乐趣（航空航天工程）。当地工业界将作为合作伙伴和参与者参与该计划。该网站的目标是：1)为每个参与者创造积极的利益（提高教师的STEM效能，改善教师和教师的课堂技术，提高本科工程专业学生的工程效能，提高保留率）；2)研究参与RET对每个参与者回归原生环境的影响；3)发现分层团队设计中最有效实现上述目标的元素，为未来RET项目的设计提供信息。

This Research Experiences for Teachers (RET) in Engineering and Computer Science Site at North Carolina State University (NCSU)will focus on understanding the role stratified teaming plays on teacher professional development and eventual learning of students in the K-12 learning environment. Previous research on teaming for undergraduate engineering students, graduate students and teachers has shown dichotomous effects for each participant. In addition to the traditional products of an RET Site, which include classroom activities and techniques linked to cutting edge research that can be taken to the K-12 clasroom, this RET will also inform the body of knowledge concerning partnerships between K-12 schools and universities. The project research will enumerate the types and depth of effects on each of the six different constituents of the teams: K-12 teachers, pre-service teachers, community college faculty, undergraduate engineering students, graduate students in engineering and university faculty. The project is a collaborative effort between NCSU College of Engineering and the University of North Carolina at Charlotte (UNCC). It will target a total of 36 in-service teachers from Durham and Charlotte-Mecklenburg County Public Schools and pre-service teachers from the Colleges of Education at NCSU and UNCC over three years. A team consisting of a K-12 teacher, a community college STEM faculty member, a pre-service teacher and an engineering undergraduate student will participate in an intensive six week summer research experience in the laboratory of a partnering engineering faculty member. Research topics will be focused on one of four sub areas of the Grand Challenges of Engineering: sustainability (solar energy), health (biomechanics), security (computer network security), and joy of living (aerospace engineering). Local industry will serve as both partners and participants in the program. The goals of the Site are to: 1) Create positive benefits for each participant (increased STEM efficacy for teachers, improved classroom technique for both teachers and faculty, increased engineering efficacy for undergraduate engineering students and enhanced retention); 2) Research the impact of participation in the RET on each participant as they return to their native environment; and 3) Discover elements of stratified team design that are most efficacious in meeting the above goals to inform the design of future RET programs.
