The initial vision for intelligent tutoring systems involved powerful, multi-faceted systems that would leverage rich models of students and pedagogies to create complex learning interactions. But the intelligent tutoring systems used at scale today ...
Technology, Knowledge and Learning Vol. 19, No. 1 (July 2014) pp. 205–220
Constructionism can be a powerful framework for teaching complex content to novices. At the core of constructionism is the suggestion that by enabling learners to build creative artifacts that require complex content to function, those learners will ...
Educational Psychologist Vol. 50, No. 1 (2015) pp. 43–57
In recent years, there has been increased interest in engagement during learning. This is of particular interest in the science, technology, engineering, and mathematics domains, in which many students struggle and where the United States needs...

As students work through online learning systems such as the Reasoning Mind blended learning system, they often are not confined to working within a single educational activity; instead, they work through various different activities such as...
Teaching of Psychology Vol. 36, No. 1 (January 2009) pp. 59–64
The online virtual world Second Life (www.secondlife.com) has multiple potential uses in teaching. In Second Life (SL), users create avatars that represent them in the virtual world. Within SL, avatars can interact with each other and with objects...
Incorporating Effective E-Learning Principles to Improve Student Engagement in Middle-School Mathematics
International Journal of STEM Education Vol. 2, No. 1 (2015)
Background: The expanded use of online and blended learning programs in K-12 STEM education has led researchers to propose design principles for effective e-learning systems. Much of this research has focused on the impact on learning, but not how...
Journal of Interactive Learning Research Vol. 29, No. 1 (January 2018) pp. 5–24
In this paper we evaluate the effectiveness of an adaptive online learning platform, designed to support Chinese students in learning the English language. The adaptive platform is studied in three studies, where the experimental platform is...
British Journal of Educational Technology Vol. 45, No. 3 (May 23, 2014) pp. 487–501
Information and communication technology (ICT)-enhanced research methods such as educational data mining (EDM) have allowed researchers to effectively model a broad range of constructs pertaining to the student, moving from traditional assessments...
Journal of the Learning Sciences Vol. 22, No. 4 (2013) pp. 639–666
We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that...
International Journal of Artificial Intelligence in Education Vol. 24, No. 2 (June 2014) pp. 189–210
We investigate the relationship between students' affect and their frequency of careless errors while using an Intelligent Tutoring System for middle school mathematics. A student is said to have committed a careless error when the student'...

International Journal of Artificial Intelligence in Education Vol. 25, No. 2 (June 2015) pp. 229–248
In recent years, there has been increasing interest in automatically assessing help seeking, the process of referring to resources outside of oneself to accomplish a task or solve a problem. Research in the United States has shown that specific help-...
Journal of Interactive Learning Research Vol. 19, No. 2 (April 2008) pp. 185–224
In recent years there has been increasing interest in the phenomena of "gaming the system," where a learner attempts to succeed in an educational environment by exploiting properties of the system's help and feedback rather than by attempting to...
International Journal of Artificial Intelligence in Education Vol. 23, No. 1 (November 2013) pp. 50–70
Recent research has extended student modeling to infer not just whether a student knows a skill or set of skills, but also whether the student has achieved robust learning--learning that enables the student to transfer their knowledge and prepares...
Generalizing Automated Detection of the Robustness of Student Learning in an Intelligent Tutor for Genetics
Journal of Educational Psychology Vol. 105, No. 4 (November 2013) pp. 946–956
Recently, there has been growing emphasis on supporting robust learning within intelligent tutoring systems, assessed by measures such as transfer to related skills, preparation for future learning, and longer term retention. It has been shown that...
From Log Files to Assessment Metrics: Measuring Students' Science Inquiry Skills Using Educational Data Mining
Journal of the Learning Sciences Vol. 22, No. 4 (2013) pp. 521–563
We present a method for assessing science inquiry performance, specifically for the inquiry skill of designing and conducting experiments, using educational data mining on students' log data from online microworlds in the Inq-ITS system ...
Student Off-Task Behavior in Computer-Based Learning in the Philippines: Comparison to Prior Research in the USA
Teachers College Record Vol. 115, No. 10 (2013)
Background: Off-task behavior can be defined as any behavior that does not involve the learning task or material, or where learning from the material is not the primary goal. One suggested path for understanding how to address off-task behavior is...
International Journal of Artificial Intelligence in Education Vol. 21, No. 1 (2011) pp. 5–25
Intelligent tutors have become increasingly accurate at detecting whether a student knows a skill, or knowledge component (KC), at a given time. However, current student models do not tell us exactly at which point a KC is learned. In this paper, we ...
