We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

This article documents our efforts to design and implement a transformational opportunity for teacher credential candidates prior to their student teaching. Through the Case Study Project, candidates participated in an intensive one-on-one teaching and learning experience with a K-12 English language learner (ELL) in classroom settings. In…

A basic question of instructional interventions is how effective it is in promoting student learning. This paper presents a study to determine the relative efficacy of different instructional strategies by applying an educational data mining technique, learning decomposition. We use logistic regression to determine how much learning is caused by…

This meta-analysis assesses the effectiveness of volunteer tutoring programs for improving the academic skills of students enrolled in public schools Grades K-8 in the United States and further investigates for whom and under what conditions tutoring can be effective. The authors found 21 studies (with 28 different study cohorts in those studies)…

Supplemental Instruction has a long history of effective use in third level education in the United States. However, there are few rigorously controlled studies in which the potentially confounding effects of student aptitude and experience and of "volunteer effects" have been controlled. Analysis of the effects of peer assisted learning…

Differential effects of a peer-tutoring intervention on the academic achievement of 203 7th-grade science students with and without disabilities in co-teaching and non-co-teaching settings were examined over an 8-week period. Impact of peer tutoring was assessed using a 2 condition by 2 settings by 2 types of students analysis of covariance with…

Assessments labeled as formative have been offered as a means to improve student achievement. But labels can be a powerful way to miscommunicate. For an assessment use to be appropriately labeled "formative," both empirical evidence and reasoned arguments must be offered to support the claim that improvements in student achievement can be linked…

The evaluation of intelligent tutoring systems (ITSs) is an important though often neglected stage of ITS development. There are many evaluation methods available but literature does not provide clear guidelines for the selection of evaluation method(s) to be used in a particular context. This paper describes the evaluation study of DEPTHS, an…

Students can practice skills and acquire knowledge by doing coursework. However, in conventional coursework activities, each student is assigned the same exercises, without considering learners' diversity. Moreover, students typically have difficulty in receiving assistance for completing their exercises after class. Therefore, some students…

The home study course described is for adults who are interested in developing skills in tutoring primary students in beginning mathematics. An outline is given of the contents of the course, and a description of the activities and resources involved in the course is provided. Ordering information for materials and a critique of the course are…

In the context of Knowledge Society, the convergence of knowledge and learning management is a critical milestone. "Intelligent Learning Infrastructure for Knowledge Intensive Organizations: A Semantic Web Perspective" provides state-of-the art knowledge through a balanced theoretical and technological discussion. The semantic web perspective…

Framed by theoretical and empirical research on cognitive and intelligent tutoring systems (ITSs), this commentary explores two areas. The first focuses on lack of conceptual clarity of the proposed constructivist stance and its related constructs. The second deals with similarities between the proposed stance and existing approaches documented in…

This summary presents features of the uTUTOR programming language. Intended for the experienced author who needs a quick reference for the form of a tag and for some of the restrictions on commands, it does not discuss fine details of the uTUTOR language. Topics covered are: (1) calculating, including operations and symbols, system functions,…

Recent evidence suggests that the use of children acting as tutors for their peers may prove beneficial to the tutor as well as to the tutee. There is now abundant, unsubstantiated anecdotal evidence, and some controlled experimental work, which suggests that the tutor benefits greatly from his involvement in teaching. The enactment of the role of…

A program in which regular class elementary students tutor their handicapped peers has proven beneficial to both tutors and tutees. (CL)
