Montessori education has a long history, but its recent growth in American public schools has led to increased interest in research efforts, particularly in exploring the potential of the Montessori experience to moderate the effects of poverty and in gathering data to evaluate public investment in Montessori schools. To assist research efforts,…

The Fullerton Longitudinal Study offers a unique opportunity to model the stability of intelligence and achievement and their relations from elementary through secondary school. Using latent variable modeling, we fit a cross-lagged panel model to examine the relations between intelligence and achievement in two academic domains: mathematics and…

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…

Educational research aims to understand how and why students change over time. With its emphasis on within-person change, latent change score models provide educational researchers with a more general and flexible framework for testing nuanced hypotheses regarding within-person change and between-person differences in within-person change. Models…

This 42-month project at the University of Denver (Colorado) developed materials and faculty development activities concerning application of Kitchener and King's reflective judgment theory. Testing and implementation were at the University of Denver and Bowling Green State University (Ohio) and the University of Missouri (Columbia). The model…

A model of conceptual learning and development that provides a framework for studying the course of cognitive development throughout the school years and also studying the learning concepts across short time intervals is discussed in this paper. The theory includes five main propositions. First, children learn four successively higher levels of…

The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…

Marginal maximum likelihood estimation equations are derived for the structural parameters of the Saltus model, and a computing approximation is suggested based on the EM algorithm. The solution is illustrated with simulated data and an example from the domain of mixed number subtraction. (SLD)

A new model is proposed for explaining children's performance on Pascual-Leone's test of M-space. The new model is used to generate theoretical performance curves for children at four different age levels and seven different levels of stimulus complexity, and it is a viable alternative. Differences between the models are reviewed. (Author/RD)

Reviews two models of thinking and intellectual development: Scandura's deterministic model of structuralistic learning, and a generalization of Rasch's probabilistic latent trait model. Models are compared by means of two experiments with balance scale tasks. (RH)

Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences…

In order to help teachers and students assess the preferred cognitive styles of individual learners, Mount Hood Community College introduced and tested the use of cognitive mapping in its orientation program. A task force of managers, counselors, and instructors: (1) decided to use the Modified Hill Model to assess nine dimensions of student…

This study examined the stability over 1-year and 2-year periods of the relationship between a cognitive measure and 2 language measures in 125 children (ages 3-7) with developmental delays. Findings indicated substantial changes in the cognitive-language relationship over time, suggesting that the discrepancy model is not appropriate for service…

Although a lot of data on the psychological characteristics of children having learning disabilities have been gathered, not very much has been done to discover the underlying mechanisms, processes, or phenomenon of learning disability. Without more investigations which attempt to get at these, we will continue to be at a loss to prescribe…

Research summarized here demonstrates how similarity thinking can be used in training programs to help ethnic minority children acquire basic skills. Current achievements are often attenuated by poor language skills, especially when English is not the first language of the child. Similarity thinking assesses the child's ability to learn without…
