This article presents an analysis of case study data from a project evaluating Personal Development Planning (PDP) at a large post-1992 university in England. The study was undertaken as part of a strategy of encouraging schools to build on existing experience while at the same time ensuring consistency with new national guidelines for the…

The extent to which a scale score generalizes to a latent variable common to all of the scale's indicators is indexed by the scale's general factor saturation. Seven techniques for estimating this parameter--omega[hierarchical] (omega[subscript h])--are compared in a series of simulated data sets. Primary comparisons were based on 160 artificial…

The authors present a Markov Chain Monte Carlo (MCMC) parameter estimation procedure for the generalized graded unfolding model (GGUM) and compare it to the marginal maximum likelihood (MML) approach implemented in the GGUM2000 computer program, using simulated and real personality data. In the simulation study, test length, number of response…

One conceptualization of meta-analysis is that studies within the meta-analysis are sampled from populations with mean effect sizes that vary (random-effects models). The consequences of not applying such models and the comparison of different methods have been hotly debated. A Monte Carlo study compared the efficacy of Hedges and Vevea's…

Participants (n = 156) were involved in the teacher preparation program at a large Research university located in the mid-west. The faculty (n = 21) participated in a two-year individualized professional development process to: 1) develop technology knowledge and skill efficacy and 2) integrate technology in teaching. The pre-service teachers (n…

Shifts in networked technologies have removed the need to store information geographically close to students, staff, and faculty on college campuses. This shift has put libraries on the offense to remain vital to the campuses they serve. As the library of the future emerges, new models for decision making that place an emphasis on the teaching and…

The field of training and development has been increasingly affected by knowledge management, performance support, and learning technologies, yet the impact of these disciplines has typically been disjointed and uncoordinated. Projects in each of the disciplines are often implemented systematically, but not systemically. To take full advantage of…

As one of the main disciplines, science is very important for people to make sense of their life. The appropriate use of the models in science classrooms to promote children's understanding, imagination and creativity definitely depends on the teachers who have experience of differentiating the scope and the limitations of the models. From this…

This case study involving three social studies teachers illustrates how the personal theorizing process, conducted as part of the teachers' preservice education, influenced their instruction during their first year of teaching. In addition, the evolution of the teachers' beliefs, as described through their personal practical theories (PPT's) of…

The purpose of the study reported in this paper was to develop a working definition of service-learning, identify the best practices of service-learning in the context of Christian colleges and universities and, based upon that information, develop a model for replication. The study undertaken included: (a) examination of the findings of…

We assessed 19-month-olds' appreciation of the conventional nature of object labels versus desires. Infants played a finding game with an experimenter who stated her intention to find the referent of a novel word (word group), to find an object she wanted (desire group), or simply to look in a box (control group). A 2nd experimenter then…

Research undertaken during a six week mountaineering expedition to Iceland in July 2003 set out to investigate approaches to facilitating the reflective process in 20 participants aged between 14 and 18. A number of models were examined to help determine the educational philosophy underpinning the expedition. The research methods involved…

Over the past 3 decades we have witnessed an increase in the complexity of theoretical models that attempt to explain development in a number of behavioral domains. The conceptual movement to examine behavior from both developmental and contextual perspectives parallels recent methodological advances in the analysis of change. These new analysis…

Problem-based learning (PBL) shifts the traditional teaching paradigm. Rather than being teacher centered, PBL is student centered. Rather than presenting content first, PBL presents the problem first. Rather than presenting the students with a well-structured problem with a clear answer, PBL presents the students with an ill-structured problem…

In this article, we propose to infuse multicultural concepts into the technology core courses that are taught in undergraduate teacher education programs. The need to do so was realized as a result of participation in a Preparing Tomorrow's Teachers to Use Technology (PT3) grant and the subsequent formation of an equity team that ultimately…
