Students with learning disabilities/difficulties in mathematics often apply ineffective procedures to solve word problems. Given that current mathematics curriculum standards emphasize conceptual understanding in problem solving as well as higher-order thinking and reasoning, the purpose of this study was to evaluate the impact of a model-based…

Gathering labeled data in educational data mining (EDM) is a time and cost intensive task. However, the amount of available training data directly influences the quality of predictive models. Unlabeled data, on the other hand, is readily available in high volumes from intelligent tutoring systems and massive open online courses. In this paper, we…

The purpose of this study was to apply a random item mixture nominal item response model (RIM-MixNRM) for investigating instruction effects. The host study design was a pre-test-and-post-test, school-based cluster randomized trial. A RIM-MixNRM was used to identify students' error patterns in mathematics at the pre-test and the post-test.…

This paper introduces a revised model for the development of basic computation skills. The model draws on four key phases, which have proven to be important for the development of calculation strategies and stresses the use of gestures and the verbalisation of concrete and mental images. This seems to be of crucial importance for children with…

Dyslexia and other learning disabilities are not being properly recognized and treated in our educational system or society at large. Unrecognized and untreated learning disabilities represent a serious social and economic problem, not only to the individual but to society as a whole. For example, antisocial behavior, as seen in prison populations…

There is little discussion in the Design-Based Research (DBR) literature on how to design an intervention that has the potential to be highly effective. The act of designing is usually viewed as engineering something from theory or research on best practices. This paper challenges that universal belief and presents successful design as an…

This study addressed the problem of why students with learning disabilities in mathematics too often fail to develop multiplicative and divisional concepts/operations. We conducted a constructivist teaching experiment with 12 students (nine 5th and three 4th graders). This report focuses on three students' conceptual progress, particularly on…

The paper describes a means to develop and implement a services delivery system for secondary level learning disabled students, which is based on surveys of secondary school teachers and administrators. The service delivery system proposed is one which can be adapted or modified to a wide variety of teaching situations. Theoretical and research…

The author reviews developments in the field of learning disabilities (LD). She traces the emergence of three models or perspectives of the causes and cures of LD: the psychological process model, the behavioral model, and the holistic model, which the author suggests is the model for the 1990's. Trends leading to acceptance of each model are…

This paper presents a rationale for teaching study skills to students with learning disabilities, a flexible study skills model, and suggestions for implementing the model. Students with learning disabilities are seen as capable of learning study skills but require specific instruction and practice and need teachers who understand learning styles,…

A multidimensional approach to assessment of children with learning difficulties is examined. The approach explores factors along five dimensions: (1) learner characteristics (motivation, social-emotional maturity, cognitive abilities and styles); (2) task-based contributors (match of tasks to maturational levels and to cognitive style); (3)…

A speech/language remediation-intervention model is proposed to enhance processing of auditory information in students with language or learning disabilities. Such children have difficulty attending to language signals (verbal and nonverbal responses ranging from facial expressions and gestures to those requiring the generation of complex…

Reported is an evaluation study involving learning disabled (LD) children (6 to 13 years old) in 23 LD programs in which children with successful outcomes were compared to children with unsuccessful outcomes. Among conclusions discussed are that Ss in the successful outcome group did not differ from those in the unsuccessful outcome group in age,…

The author describes a psychoeducational model of services for learning disability (LD) students using the British Columbia public school system. The influence of biosocial and environmental factors such as pollution and use of obstetric medication which contribute to increasing numbers of LD students are discussed. Referral, individualized…

The prevailing paradigm for understanding the causes and correction of learning and related behavior problems is seen as over-emphasizing person variables. It is suggested that an interactional model would be more in keeping with contemporary psychological theorizing and available data. Implications of understanding causal determinants in…
