In this paper, we investigate the correspondence between student affect and behavioral engagement in a web-based tutoring platform throughout the school year and learning outcomes at the end of the year, on a high-stakes mathematics exam. The relationships between affect, behavioral engagement, and learning outcomes have been previously studied, but not in a manner that is both longitudinal and...

In this paper we describe the student modeler of an adaptive and intelligent Web-based algebra tutor, which is called Web-EasyMath. The student modeling process consists of two subsequent phases. The first phase concerns the initialization of the student model, whereas the second phase is responsible for updating the student model based on the observed behavior of the student. WebEasyMath makes...

One of the important problems of cyber pedagogy is the following: how, knowing the parameters of the student, his initial level of knowledge and the impact of the teacher to predict knowledge of student at subsequent times. Simulation method allows you to create a computer program that simulates the behavior of the "teacher–student"– system and investigate the influence of system parameters on ...

We developed a new model for iList, our system that helps students learn linked list. The model is automatically extracted from past student data, and allows iList to track students’ problem-solving behavior in order to provide targeted feedback. We evaluated the new model both intrinsically and extrinsically. We show that the model can match most student actions after a relatively small sequen...

BACKGROUND In-person structured observation is considered the best approach for measuring hand hygiene behavior, yet is expensive, time consuming, and may alter behavior. Video surveillance could be a useful tool for objectively monitoring hand hygiene behavior if validated against current methods. METHODS Student hand cleaning behavior was monitored with video surveillance and in-person stru...
