Research

Cognitive Tutor Aleven, along with his colleague Kenneth Koedinger, assisted in creating Cognitive Tutor, an intelligent tutoring software that supports guided tutoring for math courses. His research investigated whether self-explanation through Cognitive Tutor could improve student performance in school more than conventional methods. Aleven and his fellow researchers found that students who explained their problems on practice problems with Cognitive Tutor regularly performed significantly better than those who did not use the software. These results highlight the benefits of self-explanation and learning software that can scale for classroom use to assist all students. Enhancing MOOCs with ITS Aleven, along with his colleagues Jonathan Sewall, Ryan Baker, Yuan Wang, and Octav Popescu introduced intelligent tutoring systems(ITS) into massive open online courses (MOOCs) to enhance learning-by-doing and overall student performance. The ITSs support learning-by-doing to assist students by guiding them through complex practice problems and having them explain their work. The researchers also embedded their Cognitive Tutor Authoring Tools(CTAT), a toolkit to create intelligent computer tutors, into MOOCs. Their research demonstrated the technical feasibility of embedding CTAT or similar ITSs into MOOCs. This works also shows the effectiveness of learning-by-doing through one-to-one coaching in online courses combined with ITS.


Adaptivity Grids and Learning Technology

In 2016, Aleven, along with his colleagues McLaughlin, Glenn, and Koedinger, examined how the effectiveness of digital tutors can be increased by adapting to the unique differences between learners, as well as to the similarities between them, such as common hurdles to solving a problem. In this paper, Aleven and colleagues introduce a tool called the Adaptivity Grid, which organizes research results in adaptivity, making it easier for developers to decide which forms of adaptivity would be best to build into their tutoring systems.
"The Adaptivity Grid shows three columns, which capture three ways in which digital tutoring systems can be adaptive to learners, namely, in their design loop, task loop, and step loop. In the design loop, the system designers use data about the targeted learners in the given task domain to create a new version of the system that is better adapted to these learners. In the task loop, the digital tutor picks problems for the student. In the step loop, the digital tutor provides assistance during steps within the problem. The Adaptivity Grid's horizontal rows show what a digital tutor can adapt to, related to the learner's traits, states, or actions."
