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.
