چکیده

The current paper focuses on modeling actions of high school students with a mathematics tutoring system with Hidden Markov Models. The results indicated that including a hidden state estimate of learner engagement increased the accuracy and predictive power of the models, both within and across tutoring sessions. Groups of students with distinct engagement trajectories were identified, and findings were replicated in two independent samples. These results suggest that modeling learner engagement may help to increase the effectiveness of intelligent tutoring systems since it was observed that engagement trajectories were not predicted by prior math achievement of students.

Investigating the Relationship Between Dialogue Structure and Tutoring Effectiveness: A Hidden Markov Modeling Approach

Identifying effective tutorial dialogue strategies is a key issue for intelligent tutoring systems research. Human-human tutoring offers a valuable model for identifying effective tutorial strategies, but extracting them is a challenge because of the richness of human dialogue. This article addresses that challenge through a machine learning approach that 1) learns tutorial modes from a corpus ...

Discovering Individual and Collaborative Problem-Solving Modes with Hidden Markov Models

Supporting students during learning tasks is the main goal of intelligent tutoring systems, and the most effective systems can adapt to students based on a model of their current state of knowledge or their problem-solving actions. Most tutoring systems focus on individual students, but there is growing interest in supporting student pairs. However, modeling student pairs involves consideration...

Modeling Strategy Use in an Intelligent Tutoring System: Implications for Strategic Flexibility

Education research has identified strategic flexibility as an important aspect of math proficiency and learning. This aspect of student learning has been largely ignored by Intelligent Tutoring Systems (ITSs). In the current study, we demonstrate how Hidden Markov Modeling can be used to identify groups of students who use similar strategies during tutoring and relate these findings to a measur...

مدل سازی فضایی-زمانی وقوع و مقدار بارش زمستانه در گستره ایران با استفاده از مدل مارکف پنهان

Multi site modeling of rainfall is one of the most important issues in environmental sciences especially in watershed management. For this purpose, different statistical models have been developed which involve spatial approaches in simulation and modeling of daily rainfall values. The hidden Markov is one of the multi-site daily rainfall models which in addition to simulation of daily rainfall...

Using Hidden Markov Models to Characterize Student Behaviors in Learning-by-Teaching Environments

Using hidden Markov models (HMMs) and traditional behavior analysis, we have examined the effect of metacognitive prompting on students’ learning in the context of our computer-based learning-by-teaching environment. This paper discusses our analysis techniques, and presents evidence that HMMs can be used to effectively determine students’ pattern of activities. The results indicate clear diffe...
