Development of an Interactive Statistics Tutorial (StatTA) to Support Inquiry-based Instruction in Biology

生物科学（61）最近的课程改革，教学介绍统计学的重点是为学生提供与数据的实践经验，并训练他们使用计算机和技术，探索探索性分析和推理程序的基本概念。 虽然计算机和统计软件已经将学生从与执行许多测试相关的计算苦差事中解放出来，但学生仍然难以选择和执行适当的统计分析，解释结果，并理解程序之间的联系和关系。 该项目的智力价值在于，它通过开发一个基于网络的交互式辅导系统和教学程序（StatTA）来解决这些教学挑战。 StatTA通过提高学生在统计实践中的能力和熟练程度来培养统计素养。 StatTA旨在支持生物学中基于探究和基于问题的活动。 它包括互动练习，演示和自我测试活动，以帮助学生选择和进行统计程序，识别图形，探索性和推理分析之间的联系，并掌握统计思维和实践的艺术。 StatTA旨在帮助教师专注于概念统计思维和解释，而不是执行测试所需的步骤和程序。 因此，学生花更少的时间学习统计软件和完成计算食谱，更多的时间学习统计学家如何处理问题和解释统计结果。 该项目更广泛的影响反映在StatTA广泛适用于将统计作为其课程一部分的科学课程。 该方案的英文和西班牙文版本正在开发中，以努力达到更多样化的观众，特别是学生的英语是第二语言。

Biological Sciences (61) Recent curricular reforms for teaching introductory statistics focus on providing students with practical experiences with data and training them in the use of computers and technology to explore fundamental concepts of exploratory analysis and inferential procedures. Although computers and statistical software have freed students from the computational drudgery associated with performing many tests, students still struggle with selecting and performing the appropriate statistical analysis, interpreting the results, and understanding the connections and relationships among procedures. The intellectual merit of this project is that it addresses these pedagogical challenges through the development of a web-based, interactive tutoring system and instructional program (StatTA). StatTA fosters statistical literacy by improving student competency and proficiency in practicing statistics. StatTA is being designed to support inquiry-based and problem-based activities in biology. It includes interactive exercises, demonstrations, and self-test activities to help students select and conduct statistical procedures, identify the connections between graphical, exploratory, and inferential analyses, and master the art of statistical thinking and practice. StatTA is intended to help instructors focus on conceptual statistical thinking and interpretation rather than the steps and procedures necessary to perform a test. Thus, students spend less time learning statistical software and completing computational recipes and more time learning how statisticians approach problems and interpret statistical results. The broader impact of the project is reflected in the wide applicability of StatTA for science courses that include statistics as part of their curricula. English and Spanish versions of the program are being developed in an effort to reach a more diverse audience, especially students for whom English is a second language.
