Modern approaches for technology-based blended education utilize a variety of recently developed novel pedagogical, computational and network resources. Such attempts employ technology to deliver integrated, dynamically-linked, interactive-content and heterogeneous learning environments, which may improve student comprehension and information retention. In this paper, we describe one such innovative effort of using technological tools to expose students in probability and statistics courses to the theory, practice and usability of the Law of Large Numbers (LLN). We base our approach on integrating pedagogical instruments with the computational libraries developed by the Statistics Online Computational Resource (www.SOCR.ucla.edu). To achieve this merger we designed a new interactive Java applet and a corresponding demonstration activity that illustrate the concept and the applications of the LLN. The LLN applet and activity have common goals - to provide graphical representation of the LLN principle, build lasting student intuition and present the common misconceptions about the law of large numbers. Both the SOCR LLN applet and activity are freely available online to the community to test, validate and extend (Applet: http://socr.ucla.edu/htmls/exp/Coin_Toss_LLN_Experiment.html, and Activity: http://wiki.stat.ucla.edu/socr/index.php/SOCR_EduMaterials_Activities_LLN).
基于技术的混合式教育的现代方法利用了各种最近开发的新颖教学、计算和网络资源。此类尝试利用技术来提供集成的、动态链接的交互式内容和异构学习环境,这可能会提高学生的理解能力和信息保留率。在本文中,我们描述了一项创新举措,即使用技术工具让概率与统计学课程的学生接触大数定律(LLN)的理论、实践和实用性。我们的方法基于将教学工具与由统计在线计算资源(www.SOCR.ucla.edu)开发的计算库相结合。为实现这种融合,我们设计了一个新的交互式Java小程序以及相应的演示活动,以阐释大数定律的概念和应用。大数定律小程序和活动有共同目标——提供大数定律原理的图形表示、培养学生持久的直觉并呈现关于大数定律的常见误解。统计在线计算资源(SOCR)的大数定律小程序和活动均可在网上免费供社区测试、验证和扩展(小程序:http://socr.ucla.edu/htmls/exp/Coin_Toss_LLN_Experiment.html,活动:http://wiki.stat.ucla.edu/socr/index.php/SOCR_EduMaterials_Activities_LLN)。
