The rstudio subdomain for stat.illinois.edu is presently a testbed for providing online analytical environments. The current active project that the domain fosters is related to autograding technologies.
There are currently two outside services that are active within this subdomain:
These services are currently restricted to students within STAT 385: Statistics Programming methods taught by James Joseph Balamuta and STAT 430: Basics of Statistical Learning taught by Dr. David Dalpiaz or faculty who wish to evaluate the use of the above services for teaching purposes.
The testbed serves as a means to not only explore online options for learning, but also represents a shift way from having students rely on personal computers. In the case of the autograde technology, the modeling building aspect is shifted from the student's machine to a remote server. This enables the ability for students to work with larger data sets than what is traditionally possible on consumer-grade hardware. Furthermore, the impact of enabling online platforms that provide autograding technology is particularly important as the number of students seeking to learn statistics is increasing exponentially. Not only does autograding technology decrease the amount of time necessary for a teaching assistant (TA) to grade homework, but also provides students with instant feedback and multiple attempts.
In Fall 2015, James Balamuta, a PhD Student within the Departments of Informatics and Statistics, deployed an autograding solution within STAT 429: Time Series Analysis taught by Prof. Stéphane Guerrier. The autograding solution was used to evaluate the effectiveness of student models on a hidden test data set with results being displayed on an anonymized leaderboard. For more information, please see the autograde project page on GitHub. Since then there are been a few different courses that have inhabited the platform.
The existence of this testbed is in part due to the support of the following individuals:
