The CATAALYST - Planning a Rigorous Study

之前对一组类似技术的研究人员称之为“CATASYST”（用于激活和评估学习和学生思维的课堂聚合技术）表明，这些快速反应的学习和教学技术可以在与适当的提问教学法相结合时，在成就和参与方面产生持续的改善。 然而，对类似CATALYST的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，通过规划活动和研讨会，设计一个方法上严格的研究在K-12数学和科学教育中的CATABLEST效应。 拟议的工作旨在解决实验设计，招聘，仪器和分析的问题，以便随后可以提出一个设计良好的研究。中心的研究问题是：一个CATABLEST干预，结合适当的教学法和教师专业发展与使能技术增加不同的学生在K-12数学和科学课堂的参与，并提高学生的成绩？该研讨会将汇集，第一次，研究人员谁调查了CATALYST（和密切相关的方法）在不同的教育水平和教学的不同subjects.Intellectual优点：对照，实验研究，研究人员打算开发将是适当的评估推理，CATALYST使这些结果。此外，它还可以区分可能影响结果的因素和对所涉机制的解释。此外，它将使研究人员能够评估本科教育中报告的先前结果是否可以在K-12环境中复制。考虑到成本的降低和技术能力的提高，K-12和大学教育工作者在STEM领域的采用越来越触手可及，但采用的决定应该基于证据。更广泛的影响：研究人员将举办一个研讨会，汇集来自不同学科社区的研究人员，他们还没有交叉授粉他们的工作。我们打算这个研讨会引出什么是已知的，以相互关联的实践为基础的帐户和理论为基础的全面的研究总结，并鼓励其他研究人员组成团队，计划额外的严格的研究。将分发一份报告，记录知识基础和跨学科科学家小组如何进一步协调一致。

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.
