Keywords: Number sense; Learning curve; Logistic model analysis

These is my summer school project about students' math game performance in RoboTutor.

We uncovered the potential learning difficulties that K-2 students faced while learning about missing number completion in a tablet-based program called RoboTutor. We analyzed 185,064 rows of log-data from 283 students to determine the tutor pass rates and made learning curves for each activity within that knowledge component.

My Role
As a new researcher to Educational Data Mining, I ...

Learned to use Datashop and made learning curves during 5-day summer school

Cleaned and managed student problem-solving log data in Robotutor from 96 different activities.

Applied logistic model analyses to understand factors that influence students’ error ratesparticipants.

Made a oral presentation and poster presentation in front of all the summer school participants.
