Enhancing Quality Undergraduate Investigations Physical

项目摘要

Prospective elementary school teachers are often provided with limited opportunities to engage in authentic scientific investigations in physical science laboratories during their teaching preparation. As a result, teachers commonly struggle to explain scientific phenomena and to facilitate investigations in schools. The Enhancing the Quality of Undergraduate Investigations in Physical Science (EQUIPS) project will study the impact of re-designed physical science laboratories on prospective pre-service elementary education (PSEE) teachers' explanations of physical science phenomena and experimental practices, as well as the impact of such laboratory experiences on their future instruction. These re-designed laboratories will move away from cookbook-style approaches to laboratories that challenge teachers to develop and conduct their own investigations of physical science phenomena. EQUIPS will provide critical insight in laboratory design for increased decision-making and in assessment design of scientific phenomena and experimental practice explanations, and how such laboratory experiences transfer to future instructional practice. EQUIPS laboratories will avoid the fragmentation of separate physics and chemistry labs, integrate the assessments of teachers' understandings of physical science phenomena in physics and chemistry, and provide PSEE teachers with strategies for facilitating investigations that guide children in experimental design, data interpretation, scientific discourse, and understanding of disciplinary core ideas, practices, and crosscutting concepts associated with chemistry and physics. This is consistent with the 3-dimentional learning called for in the Next Generation Science Standards (NGSS). Such changes in physical science laboratory experiences will ultimately support better science instruction in the physical sciences for K-8 students. Further, EQUIPS will engage a large proportion of first generation teachers and underrepresented groups in the physical sciences as it is designed, tested and implemented at an Hispanic-serving institution. Thus, this Improving Undergraduate STEM Education (IUSE) Exploration and Design project will contribute to the redesign of undergraduate pre-service elementary education and advance the potential of teachers to create learning environments in which elementary students can experience success when engaging with phenomena in the physical sciences.Through design and comparison studies over six semesters with approximately 120 PSEE teachers each semester (720 total), EQUIPS will develop, test, and refine new NGSS aligned laboratory curriculum that support and target disciplinary and integrated explanations of scientific phenomena in the physical sciences and understanding of experimental practices. Pre/post items will be developed alongside knowledge integration rubrics to score students' conceptual development. Laboratory curriculum will follow an anchor phenomenon (broad, complex, and difficult to investigate directly) and an investigative phenomenon (testable questions that in part answer the broader anchor phenomenon) framework. Additional data will be collected through observations, questionnaires, and interviews to identify improvements for the laboratory curriculum. Finally, case studies involving observations and interviews will be conducted with select teachers during and after degree completion to determine the impacts of the laboratory curriculum on their instruction. EQUIPS will use design-based research to investigate three research questions: How do PSEE teachers explain a scientific phenomenon using different science disciplines and how integrated are these explanations? How can laboratories be designed to support experimental practices and what impact does this have on undergraduates' explanations of scientific phenomena compared to existing laboratories? What impact do redesigned laboratories have on PSEE teachers' views about experimental practices and physical science, and in turn, uptake of the course? The curriculum materials, assessments, and findings resulting from this investment will be disseminated through publications, conference presentations, workshops, and social media outlets. As such, EQUIPS will provide other institutions with an important blueprint to guide the re-design of their elementary teacher science courses towards effective laboratory experiences for PSEEs in support of elementary students' successful learning of and engagement with physical science phenomena. This important work is supported with funding from the IUSE program and the Robert Noyce Teacher Scholarship program.

在备课过程中，准小学教师参与物理科学实验室真实科学调查的机会往往有限。因此，教师们通常都在努力解释科学现象，并促进学校的调查。“提高本科物理科学研究质量（EQUIPS）”项目将研究重新设计的物理科学实验室对未来职前基础教育（PSEE）教师对物理科学现象和实验实践的解释的影响，以及这些实验室经历对他们未来教学的影响。这些重新设计的实验室将从烹饪书式的方法转向挑战教师发展和开展他们自己对物理科学现象的调查。EQUIPS将为实验室设计提供关键的见解，以增加科学现象和实验实践解释的决策和评估设计，以及如何将这些实验室经验转移到未来的教学实践。EQUIPS实验室将避免分离的物理和化学实验室的碎片化，整合教师对物理和化学中物理科学现象的理解的评估，并为PSEE教师提供促进调查的策略，指导儿童进行实验设计，数据解释，科学话语，以及对学科核心思想的理解，实践，以及与化学和物理相关的横切概念。这与下一代科学标准（NGSS）所要求的三维学习是一致的。物理科学实验室经验的这种变化最终将为K-8学生提供更好的物理科学教学。此外，EQUIPS在为西班牙裔服务的机构设计、测试和实施时，将吸引很大一部分第一代教师和物理科学领域代表性不足的群体。因此，这个改进本科STEM教育（IUSE）探索和设计项目将有助于重新设计本科职前基础教育，并提高教师创造学习环境的潜力，使小学生在参与物理科学现象时能够体验到成功。通过每学期约120名PSEE教师（共720名）的六个学期的设计和比较研究，EQUIPS将开发、测试和完善新的NGSS一致的实验课程，以支持和目标学科和物理科学现象的综合解释以及对实验实践的理解。课前/课后项目将与知识整合规则一起开发，以对学生的概念发展进行评分。实验课程将遵循锚点现象（广泛、复杂、难以直接调查）和调查现象（可测试的问题，部分回答更广泛的锚点现象）框架。其他数据将通过观察、问卷调查和访谈收集，以确定对实验课程的改进。最后，案例研究包括观察和访谈，将在学位完成期间和之后与选定的教师进行，以确定实验课程对其教学的影响。EQUIPS将使用基于设计的研究来调查三个研究问题：PSEE教师如何使用不同的科学学科来解释科学现象，这些解释是如何整合的？如何设计实验室以支持实验实践？与现有实验室相比，这对本科生对科学现象的解释有什么影响？重新设计的实验室对PSEE教师对实验实践和物理科学的看法产生了什么影响，进而对课程的吸收产生了什么影响？这项投资的课程材料、评估和结果将通过出版物、会议报告、研讨会和社交媒体渠道传播。因此，EQUIPS将为其他机构提供一个重要的蓝图，指导他们重新设计小学教师科学课程，以有效地为psee提供实验室体验，以支持小学生成功学习和参与物理科学现象。这项重要的工作得到了IUSE项目和Robert Noyce教师奖学金项目的资助。
