چکیده

The ASSISTment system was used by over 600 students in 2004-05 school year as part of their math class. While in [7] we reported student learning within the ASSISTment system, in this paper we focus on the assessment aspect. Our approach is to use data that the system collected through a year to tracking student learning and thus estimate their performance on a high-stake state test (MCAS) at the end of the year. Because our system is an intelligent tutoring system, we are able to log how much assistance students needed to solve problems (how many hints students requested and how many attempts they had to make). In this paper, our goal is to determine if the models we built by taking the assistance information into account could predict students' test scores better. We present some positive evidence that shows our goal is achieved.

The Effect of Model Granularity on Student Performance Prediction Using Bayesian Networks

A standing question in the field of Intelligent Tutoring Systems and User Modeling in general is what is the appropriate level of model granularity (how many skills to model) and how is that granularity derived? In this paper we will explore varying levels of skill generality within 8 grade mathematics using models containing 1, 5, 39 and 106 skills. We will measure the accuracy of these models...

Looking for Sources of Error in Predicting Student’s Knowledge

Recent research has focused on detecting the “gaming” behavior of students while using an intelligent tutoring system. For instance, Baker, Corbett & Koedinger (2004) reported detecting “gaming” by students, and argued that it explained lower learning results for these students. In this paper, we report that while our computer system’s correlation with a student’s actual state test score is wel...

Knowledge Engineering for Intelligent Tutoring Systems: Using machine learning assistance to help humans tag questions to skills based upon the words in the questions

Building a mapping between items and their related knowledge components, while difficult and time consuming, is central to the task of developing affective intelligent tutoring systems. Improving performance on this task by creating a semi-automatic skill encoding system would facilitate the development of such systems. The goal of this project is to explore techniques involved in text classifi...

Assessing Entailer with a Corpus of Natural Language from an Intelligent Tutoring System

In this study, we compared Entailer, a computational tool that evaluates the degree to which one text is entailed by another, to a variety of other text relatedness metrics (LSA, lemma overlap, and MED). Our corpus was a subset of 100 self-explanations of sentences from a recent experiment on interactions between students and iSTART, an Intelligent Tutoring System that helps students to apply m...
