Results of three methods of analysis applied to simulated autocorrelated data sets with an intervention point (varying in autocorrelation degree, variance of error term, and magnitude of intervention effect) are compared and presented. The three methods are: t tests; maximum likelihood Box-Jenkins (ARIMA); and Bayesian Box Jenkins. (Author/AEF)

Discusses four models of needs analysis: Kaufman's "Needs Assessment," Coffing's "Client Need Assessment," Lee's "Needs-Assessment," and Harless'"Front-End Analysis." A matrix comparing these models is included. (RAO)

Compared strategies for performing multiple comparisons with nonnormal data under various data conditions, including simultaneous violations of the assumptions of normality and variance homogeneity. Monte Carlo study results show the conditions under which different strategies are most appropriate. (SLD)

Discusses the utility of multilevel confirmatory factor analysis and hierarchical linear modeling methods in testing measurement models in which the underlying attribute may vary as a function of levels of observation. A real dataset is used to illustrate the two approaches and their comparability. (SLD)

In this project, students compare the makeup of a cell to an everyday working unit or system. They create a three-dimensional object that represents their analogy. For example, students could create a car motor or manufacturing plant. (Of course, this is totally hand-created by them, so it can be a homemade re-creation of a system, not an actual…

The National Board for Professional Teaching Standards (NBPTS) assesses teaching practice based on videos and essays submitted by teachers. We compared the performance of classrooms of elementary students in Los Angeles randomly assigned to NBPTS applicants and to comparison teachers. We used information on whether each applicant achieved…

Intergroup attitudes in children were examined based on Leyen's "infrahumanization hypothesis". This suggests that some uniquely human emotions, such as shame and guilt (secondary emotions), are reserved for the in-group, whilst other emotions that are not uniquely human and shared with animals, such as anger and pleasure (primary…

Skin cancer is highly preventable, but clearly there is a critical need to focus on better ways to disseminate information about known skin cancer prevention. The U.S. Environmental Protection Agency's (EPA) SunWise Program is one channel for reaching children, teachers, and school nurses. In a pilot study designed to increase adoption of…

Classroom management is a concern for preservice teachers (Charles, 2008). Teacher educators struggle to find the most effective ways to teach preservice teachers classroom management. Role-playing, combined with classroom management content, may offer a productive approach. As such, this study focused on the use of role-play with case studies to…

One of the central challenges in mastering English is becoming sensitive to consistency from spelling to sound (i.e. phonological consistency) and from sound to spelling (i.e. orthographic consistency). Using functional magnetic resonance imaging (fMRI), we examined the neural correlates of consistency in 9-15-year-old Normal and Impaired Readers…

How does one know whether traditional or innovative staff development is working? This study compared the effects of professors' attitudes toward learning through traditional staff development versus alternative instructional strategies for teaching community college students. Eight-four professors participated in this study. The average…

Egalitarian and participation-oriented teaching emphasizes critical discussion and informal relationships between students and professors. The authors argue that the use of egalitarian and some aspects of participation-oriented teaching at business schools differs systematically across countries according to the strength of democratic culture.…

The numerical knowledge of children from low-income backgrounds trails behind that of peers from middle-income backgrounds even before the children enter school. This gap may reflect differing prior experience with informal numerical activities, such as numerical board games. Experiment 1 indicated that the numerical magnitude knowledge of…

This study is a secondary analysis of data from the 1995 administration of the Third International Mathematics and Science Study (TIMSS). The purpose is to compare the breadth, depth, and recurrence of the typical physics curriculum in the United States with the typical curricula in different countries and to determine whether there are…

Two studies were conducted to investigate the effects of cooperative learning on second-graders' motivation and learning from text. In Study 1, students (n = 160) in cooperative learning groups were compared with their counterparts (n = 107) in traditional instruction groups. The results revealed a statistically significant difference between the…
