摘要

我们研究了在线代数辅导项目“动物观察”对六年级学生数学成绩的影响。我们使用的数据来自于2011-2012学年对加州69名教师和2025名学生进行的随机实验设计。在简要描述了实验设计和系统实现之后，我们使用流行的层次线性模型分析了使用AnimalWatch的治疗效果，并发现了一个小的积极效果。我们进一步使用记录的系统使用数据，如在系统中花费的时间，完成的模块，每次登录学生的正确/错误/无答案记录，来分析系统的实现和使用如何帮助不同的学生。我们的研究结果提供了在现实世界中实施此类研究的局限性的见解，并为未来的研究提出了建议。

The Impact of an Online Tutoring Program for Algebra Readiness on Mathematics Achievements; Results of a Randomized Experiment

We study the impact of an online tutoring program, AnimalWatch, for algebra readiness on mathematics achievements of grade 6 students. We use the data from a randomized experimental design conducted on 69 teachers and 2025 students in California in the academic years 2011-2012. After a brief description of the experimental design and the system implementation, we analyze the treatment effect of employing AnimalWatch using the popular hierarchical linear models and find a small positive effect. We further use the logged system usage data such as time spent in the system, modules completed, correct/incorrect/no-answers records of students in each login to analyze how system implementation and usage helped different students. Our results provide insights into the limitations in implementing such a study in a real world setting and suggests recommendations for future research.
