This study analyzes the short-term consequences of visitors' use of different types of exhibits (i.e., "exemplars of phenomena" and "analogy based") together with the factors affecting visitors' understanding of and their evaluation of the use of such exhibits. One hundred and twenty five visitors (either alone or in groups) were observed …

This article describes results related to leadership that emerged from a series of studies commissioned by the Networked Learning Group of the National College of School Leadership to draw on the experiences of the Networked Learning Communities (NLC) Programme, with a view to informing the work of other groups and agencies in England and beyond…

Hierarchical classes models are quasi-order retaining Boolean decomposition models for N-way N-mode binary data. To fit these models to data, rationally started alternating least squares (or, equivalently, alternating least absolute deviations) algorithms have been proposed. Extensive simulation studies showed that these algorithms succeed quite…

The theory of signal detection is convenient for measuring mnemonic ability in recognition memory paradigms. In these paradigms, randomly selected participants are asked to study randomly selected items. In practice, researchers aggregate data across items or participants or both. The signal detection model is nonlinear; consequently, analysis…

Bounds are established for log odds ratios (log cross-product ratios) involving pairs of items for item response models. First, expressions for bounds on log odds ratios are provided for one-dimensional item response models in general. Then, explicit bounds are obtained for the Rasch model and the two-parameter logistic (2PL) model. Results are…

What people know about higher education may depend on which data they look at and how they examine them. Responsible analysts should present a full picture of their sources of data and the limitations of those sources, restricting their conclusions to those that the data genuinely warrant. When new research conflicts with previous results, enough…

This study introduces a novel application of structural equation modeling (SEM) for the analysis of cortisol data that are collected using a pre-post-post design. By way of an extended example, an SEM model is developed that permits an examination of both the overall level of cortisol, as well as changes in cortisol (reactivity and regulation), as…

Teachers in the United States are utilizing technology in their classrooms on a daily basis. However, some schools struggle to implement effective technology usage opportunities for staff. In a 21st century world that is laden with technology, teachers should instruct students using updated technology. In two rural Virginia high schools in eastern…

This paper situates school-to-work transitional purpose of VETiS in Queensland by comparison of young adults who complete Year 12 for their different groups such as gender, geographic location, indigenous and socio-economic status. The literature indicates that students' educational outcomes are related to their social environment and culture, an…

The purpose of this study is to expand understanding and discover knowledge about degree attainment among adult learners. This qualitative inquiry explores what recent non-traditional-age bachelor's degree recipients report contributes to attaining the degree. Professional research and expert material on demographics, motivation, challenges and…

This study examined mathematics achievement of fourth and fifth grade students in Mississippi and principals' perceptions of inclusion. A sample of 462 students from eight separate elementary schools was selected for this study. Fifteen principals completed the Principal and Inclusion Survey regarding inclusion education. Eight of the 15…

How do the best administrators find out how to improve their schools? They actively engage the people who work and study there. In "From Questions to Actions: Using Questionnaire Data for Continuous School Improvement," data experts Victoria L. Bernhardt and Bradley J. Geise explain how to collect and analyze data with an eye toward positive…

This technical paper contains information about the variables in the Longitudinal Surveys of Australian Youth (LSAY) Year 1998 cohort data set. It groups each variable into data elements which identifies common variables within and across waves. Information is provided about each data element including its purpose, values, base populations and…

In 2004, the Afterschool Alliance and the JCPenney Afterschool Fund commissioned the most in-depth study ever to examine how America's kids spend their after school hours--"America After 3PM". In spring 2009, the Afterschool Alliance and the JCPenney Afterschool Fund again worked with RTi to update the study to determine how things have…

Each day in America, millions of kids go home to an empty house after school. In recent years, the growth of quality, affordable afterschool programs--programs that keep kids safe, inspire learning and help working families--has begun to offer parents of these children positive alternatives. Over the past five years, afterschool programs have…
