The CATAALYST - Planning a Rigorous Study

研究人员之前对一组类似技术的研究表明，这些快速反应的学习和教学技术在配合适当的提问教学方法时，可以在成就和参与度方面产生持续的改善。然而，对CATAALYST类技术的研究在质量和数量上都是有限的。因此，研究人员建议，通过规划活动和一个研讨会，在方法上对K-12数学和科学教育中的CATAALYST效应进行严格的研究。拟议的工作旨在解决实验设计、招募、仪器和分析的问题，以便随后能够提出设计良好的研究。中心的研究问题是：CATAALYST干预结合了适当的教育学和教师专业发展与使能技术，是否增加了K-12数学和科学课堂上不同学生的参与，并提高了学生的成绩？研讨会将首次聚集研究CATAALYST(及其密切相关的方法)的研究人员，他们在不同的教育水平和不同的学科教学中进行研究。智力价值：研究人员打算开发的受控实验研究将适合于评估CATAALYST使这些结果得以实现的推论。它还可以区分影响结果的可能因素和对所涉机制的解释。此外，它将使研究人员能够评估在本科教育中报告的先前结果是否可以在K-12设置中复制。鉴于成本的降低和技术能力的提高，STEM的K-12和大学教育工作者越来越容易采用，但采用的决定应该基于证据。此外，实施应该建立在对涉及的因素和机制的理解的基础上。广泛的影响：调查人员将举办一个研讨会，将尚未交叉授粉的不同学科社区的研究人员聚集在一起。我们打算通过这次研讨会对已知情况进行全面的研究总结，将基于实践和基于理论的描述联系起来，并鼓励其他研究人员组建团队，计划更多的严格研究。将分发一份报告，记录知识库和跨学科科学家团队如何更好地协调工作。

Prior research on a group of similar technologies that the investigators call "CATAALYST" (Classroom Aggregation Technology for Activating and Assessing Learning and Your Students' Thinking) suggests that these rapid response learning and instructional technologies can produce sustained improvements in achievement and participation when coupled with an appropriate pedagogy of questioning. Yet research on CATAALYST-like technologies is limited in quality and quantity. As a result, the investigators propose, through planning activities and a workshop, to devise a methodologically rigorous study of CATAALYST effects in K-12 math and science education. The proposed work seeks to resolve issues of experimental design, recruitment, instrumentation, and analysis so that a well-designed study subsequently can be proposed. The central research question is: Does a CATAALYST intervention that combines an appropriate pedagogy and teacher professional development with the enabling technology increase participation among diverse students in K-12 math and science classrooms and increase student achievement?The workshop will bring together, for the first time, researchers who have investigated CATAALYST (and closely-related approaches) at different educational levels and for the teaching of different subject matters.Intellectual Merit:The controlled, experimental study that the investigators intend to develop will be appropriate for evaluating the inference that CATAALYST enables these outcomes. It may additionally differentiate among possible factors contributing to the outcomes and explanations of the mechanisms involved. Further, it will enable the researchers to evaluate whether prior outcomes reported in undergraduate education can be replicated in K-12 settings. Given decreasing costs and increasing capabilities of the technology, adoption is increasingly within reach for K-12 and university educators in STEM, but decisions to adopt should be based on evidence. Further, implementations should be based on understanding of the factors and mechanisms involved.Broader Impacts:The investigators will hold a workshop to bring together researchers from different disciplinary communities who have not yet cross-pollinated their work. We intend this workshop to elicit comprehensive research summaries of what is known, to interrelate practice-based and theory-based accounts, and to encourage other researchers to form teams to plan additional rigorous studies. A report will be disseminated, documenting both the knowledge base and how interdisciplinary teams of scientists could proceed in greater alignment.
