Students should have exposure to social justice education (SJE) through the content-based curriculum or through cocurricular learning opportunities. This program evaluation study used qualitative data collection and analysis procedures to determine how to best improve the cocurricular SJE program, Lead for Diversity (LFD), which is used in high…

We develop an Easy Java Simulation (EJS) model for students to experience the physics of idealized one-dimensional collision carts. The physics model is described and simulated by both continuous dynamics and discrete transition during collision. In designing the simulations, we discuss briefly three pedagogical considerations namely (1) a…

The National Science Foundation's (NSF) National Science Digital Library/Distributed Learning (NSDL) program turned 10 years old in 2010. This report presents results of a preliminary program evaluation carried out by RAND and is organized around three principal goals: (1) Provide an initial evaluation of NSDL based on existing information…

A disconnect exists between principal leadership expectations and the actual practice of supervision and evaluation of principals. Increased principal responsibilities and rigorous standards require that a new approach to principal evaluation be considered. The authors provide a framework for a multi-dimensional approach to principal supervision…

Though research in emerging technologies is vital to fulfilling their incredible potential for educational applications, it is often fraught with analytic challenges related to large datasets. This thesis explores these challenges in researching multiuser virtual environments (MUVEs). In a MUVE, users assume a persona and traverse a virtual space…

This article is the fourth in a series of articles describing an attrition prediction and intervention project at the University of South Florida (USF) in Tampa. In this article, the researchers describe the updated version of the prediction model. The original model was developed from a sample of about 900 First Time in College (FTIC) students…

Rett syndrome (RTT) is a rare genetic disorder within the autistic spectrum. This study compared socio-demographic, clinical and genetic characteristics of the international database, InterRett, and the population-based Australian Rett syndrome database (ARSD). It also explored the strengths and limitations of InterRett in comparison with other…

Von Davier, Holland, and Thayer (2004) laid out a five-step framework of test equating that can be applied to various data collection designs and equating methods. In the continuization step, they presented an adjusted Gaussian kernel method that preserves the first two moments. This article proposes an alternative continuization method that…

This study sought to understand the process of change elementary teachers experienced as they participated in mathematics professional development. This investigation explored the impact of mathematics professional development on teachers' content knowledge for teaching, their ability to implement innovative pedagogical practices, and the…

This paper illustrates how information collected through interviews can develop a richer understanding of the assignment mechanism, which can result in more plausible causal effect estimates from observational studies and provides a roadmap for sensitivity analysis. Focusing on the issue of assignment to algebra in 8th grade, the author shows how…

Developing a descriptive framework is one step in the complex process of theory development in qualitative research. This complexity is especially evident when analysing data about how teachers interpret the inherent moral significance of their classroom interactions. A common way of gathering data is to follow an iterative process, in which both…

This study investigated the conceptual pathways of 19 Grade 11 introductory chemistry students (age 16-17) as they participated in a multirepresentational instruction on the particulate nature of matter (PNM). This study was grounded in contemporary conceptual change theory, in particular, research on students' conceptual pathways that focuses on…

Latent growth-mixture modeling was used to investigate patterns of change in loneliness for 170 children from third through fifth grades. A three-class model representing unique trajectories of loneliness provided the best overall fit to the data, including a Stable Low group (65%), as well as groups of Increasers (23%) and Decreasers (12%).…

Purpose: The purpose of this paper is to argue that both the supply-based model and the demand-based form of vocational education and training (VET) have their limitations and propose a "third way" in which reflective learning in the workplace is a central ingredient. Design/methodology/approach: The data was collected from several…

Promoting self-determination has been identified as best practice in special education and transition services and as a means to promote goal attainment and access to the general education curriculum for students with disabilities. There have been, however, limited evaluations of the effects of interventions to promote self-determination on…
