One of the essential problems, in educational data mining, is to predict students' performance on future learning materials, such as problems, assignments, and quizzes. Pioneer algorithms for predicting student performance mostly rely on two sources of information: students' past performance, and learning materials' domain knowledge model. The…

We present a quantitative model for predicting the level of difficulty subjects will experience with specific problems. The model explicitly accounts for the number of subproblems a problem can be broken into and the difficultly of each subproblem. Although the model builds on previously published models, it is uniquely suited for blending with…

This report presents research concerned with two information-processing constructs, "cognitive strategies" and "cognitive styles." Study one analyzes thinking-aloud protocols obtained from a female undergraduate doing anagram problems. Several major strategies are described, along with basic "Operators" subject used to construct and modify…

Difficulties facing learning disabled (LD) students in problem solving are reviewed and an approach is proposed to help them make better use of the learning strategies available to them. A cognitive learning style approach to LD students is introduced, followed by an analysis of problem solving and the stages of information processing (attention,…

Cognitive style, the impulsivity-reflectivity dimension, is reviewed as an individual difference that does significantly affect a learning/teaching situation. Relevance of impulsivity-reflectivity for learners in a problem-solving situation is established. Conclusions emphasize the importance of this individual difference. (Author)

The purpose of this study was to determine whether or not children manifesting different cognitive styles also behave differently in small-group instructional situations. Six groups of seven children each engaged in a small group videotaped learning experience in which they were to learn the English equivalent of 75 symbols. Analysis of the data…

This paper presents a general framework for the process of answering questions from memory. The focus is primarily on verification and recognition tasks. Six experiments support the assumptions of the proposed framework. The experiments are designed to address the following categories of inquiry: (1) Can we adjust our strategy preference to mirror…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 20 titles deal with a variety of topics, including the following: use of word information cues by beginning readers; the relationship between problem solving and oral reading strategies; the ease with which children learn…
