چکیده

Cognitive Tutors are primarily developed as instructional systems, with the goal of helping students learn. However, the systems are inherently also data collection and assessment systems. In this paper, we analyze data from over 3,000 students in a school district using Carnegie Learning’s Middle School Mathematics tutors and model performance on standardized tests. Combining a standardized pretest score with interaction data from Cognitive Tutor predicts outcomes of standardized tests better than the pretest alone. In addition, a model built using only 7th grade data and a single standardized test outcome (Virginia’s SOL) generalizes to additional grade levels (6 and 8) and standardized test outcomes (NWEA’s MAP).

Generalizing and Extending a Predictive Model for Standardized Test Scores Based On Cognitive Tutor Interactions

Recent work demonstrates that process data from intelligent tutoring systems (ITSs) can be used to predict student outcomes on high-stakes, standardized tests. Such models are important if ITSs are to be used for formative assessment and as replacements for external assessments. Recent work used various measures of learning efficiency and performance from problem-level, aggregate data from Carn...

Ensembling Predictions of Student Post-Test Scores for an Intelligent Tutoring System

Over the last few decades, there have been a rich variety of approaches towards modeling student knowledge and skill within interactive learning environments. There have recently been several empirical comparisons as to which types of student models are better at predicting future performance, both within and outside of the interactive learning environment. A recent paper (Baker et al., in pres...

Investigations into Help Seeking and Learning with a Cognitive Tutor

In order to develop tutoring systems that strike a better balance between system control and student control, or systems that provide guidance and feedback in order to help students learn help-seeking skills, we need a better understanding of (actual and ideal) help seeking. In this paper, we take modest steps toward this goal: First, we continue to assess students help-seeking behaviour in the...

Predicting Students Performance with SimStudent that Learns Cognitive Skills from Observation

SimStudent is a machine-learning agent that learns cognitive skills by demonstration. SimStudent was originally built as a building block for Cognitive Tutor Authoring Tools to help an author build a cognitive model without heavy programming. In this paper, we evaluate a second use of SimStudent for student modeling for Intelligent Tutoring Systems. The basic idea is to have SimStudent observe ...

Predicting cognitive change in older adults: the relative contribution of practice effects.

Assessing cognitive change in older adults is a common use of neuropsychological services, and neuropsychologists have utilized several strategies to determine if a change is "real," "reliable," and "meaningful." Although standardized regression-based (SRB) prediction formulas may be useful in determining change, SRBs have not been widely applied to older adults. The current study sought to dev...
