In this study, a large number of observers (N=201) were asked to segment a collection of outlines derived from line drawings of everyday objects (N=88). This data set was then used as a benchmark to evaluate current models of object segmentation. All of the previously proposed rules of segmentation were found supported in our results. For example,…

In this exploratory study we compare and report two ways in which instructors describe their teaching: (a) thinking about a course they are teaching, (b) thinking about specific classes within that course. Extensive interviews over an extended time provided the data for analysis. At the course level, we analyzed comments about teaching decisions…

Although there are many methods available for dimensionality assessment for items with monotone item response functions, there are few methods available for unfolding item response theory models. In this study, a modification of Yen's Q3 statistic is proposed for the case of these nonmonotone item response models. Through a simulation study, the…

Previous studies of the Stroop task propose two key mediators: the prefrontal and cingulate cortices but hints exist of functional specialization within these regions. This study aimed to examine the effect of task modality upon the prefrontal and cingulate response by examining the response to colour, number, and shape Stroop tasks whilst BOLD…

This article provides an overview of the 2002 American Association on Mental Retardation's (AAMR's) "Definition, Classification, and Systems of Supports" (the 2002 System) and discusses its relationship to salient international trends and several scientific and judgmental issues currently impacting the field of intellectual disabilities (ID). Five…

Instructional design has numerous approaches and theories available for use by designers and instructors. One model was particularly effective in providing developers with a generic, systematic framework that was easy to use and applicable to a variety of settings. The ADDIE model was utilized in two ways in a Master's level instructional design…

Drawn by a vision of solving performance problems in a systematic, systemic and results-based approach, training professionals are turning to human performance technology (HPT). However, many who try to implement HPT find themselves struggling to measure the improvements their interventions are designed to achieve. Ford notes that these…

An international movement has focused on identifying evidence-based interventions that were developed to change psychological constructs and that are supported by controlled studies. However, inconsistent findings within individual intervention studies and among multiple studies raise critical problems in interpreting the evidence, and deciding…

Currently there is much debate about the gap between business schools and the business world (Gosling and Mintzberg, 2004; Bennis and O'Toole, 2005). One argument is that business schools focus too much on "scientific" research and lack relevant business context and real-world experience. The proposition in this paper is that the dynamics in the…

According to the author, teachers must give their students the ability to assess past, present, and new technologies, while making them aware that there is always a price to pay for any new technology. Students need to acquire the ability to make critical decisions about the world they live in and the technologies that will impact their lives. In…

Federal and state policies have long sought to address the social inequities faced by limited English proficient (LEP) students through the improvement of English language acquisition. English language acquisition policy has focused on access to resources, qualified teachers, and instructional methodologies (e.g. pedagogy) that create a learning…

The presentation will trace the experiences of two program directors from Walden University and their examination of issues involved with faculty assessment. Their experiences were used to create a simple but effective and workable model for faculty assessment and development. Once a presentation of how data were obtained, and analyzed, to create…

The goal of this study was to determine the level of educational expenditure necessary to make ample provision for the education of all students, providing all students with the skills to meet long-term academic standards, pursue additional learning beyond high school, and become productive citizens and contributing members of society. This study…

This book presents 16 teaching techniques organized in lessons to be used by teachers who work with adolescents or young adults. The lessons may be used by individuals or in groups to improve instructional skills. A study guide or meeting plan precedes each chapter and suggests objectives, anticipatory set, input and modeling, means to check…

The purpose of this study was to examine the extent to which preservice elementary teachers were able to construct viable scientific models with a computer-modeling tool, namely Model-It, and design a science lesson with models. The results of the study showed that (a) Model-It, through its scaffolds (i.e., Plan, Build, and Test modes), enabled…
