The objective of this article is to study the network and virtual reality technologies for developing a virtual dinosaur museum, which provides a Web-learning environment for students of all ages and the general public to know more about dinosaurs. We first investigate the method for building the 3D dynamic models of dinosaurs, and then describe…

In a nonrandomized or observational study, propensity scores may be used to balance observed covariates and trajectory groups may be used to control baseline or pretreatment measures of outcome. The trajectory groups also aid in characterizing classes of subjects for whom no good matches are available and to define substantively interesting groups…

Social avoidance is a core phenotypic characteristic of fragile X syndrome (FXS) that has critical cognitive and social consequences. However, no study has examined modulation of multiple social avoidant behaviors in children with FXS. In the current study, we introduce the "Social Approach Scale" (SAS), an observation scale that includes physical…

Background: Attaining a developmentally sensitive nosology for preschool disruptive behavior requires characterization of the features that distinguish it from the normative misbehavior of this developmental period. We hypothesize that "quality of behavior and its pervasiveness across contexts" are critical dimensions for clinical discrimination…

This descriptive study documents the effects of response-to-intervention type practices in four first-grade classrooms of English learners (ELs) from 11 native languages in three schools in a large urban school district in southern California. Observations and interviews in four classrooms across two consecutive years were compared to first-grade…

This paper examines and analyses where and how information and communication technologies (ICT) are integrated in Singapore schools to engage students in higher-order thinking activities. Taking the activity system as a unit of analysis, the study documents the actual processes and sociocultural elements that engage students in higher-order…

In 2003, the Office of Juvenile Justice and Delinquency Prevention (OJJDP) provided Florida's Department of Juvenile Justice (DJJ) with a $3.5 million grant to design and implement a faith- and community-based program for incarcerated juveniles. Florida's experience developing a completely new program has provided valuable lessons regarding…

A study examined peer response groups in two ninth grade English classes. The study specifically investigated research considerations including: (1) the teachers' use of response groups; (2) the kinds of response the students give themselves in response groups; and (3) the connection between student response and the teachers' directions to the…

The authors present a program of research on the teaching practices of 1st-year teachers that has evolved within a partnership between and among a university and area school districts. The research links observed 1st-year teaching practices with school level (elementary, middle, high school) and type of teacher preparation (traditional bachelor's…

With the enactment of the NCLB mandates, emphasis on high-stakes testing became more prevalent than ever. Some argue that high-stakes tests can be a driving force behind fundamental change in schools. Whether or not this type of test-driven change leads to school improvement is an empirical question. What we do know is that high-stake testing can…

This in-progress study presents aspects of using educational technology in teaching mathematics education. More exactly, it explores ways in which educational technology might be used in order to improve teachers' cultural awareness and social activism. A rationale for a qualitative research study is presented by using multiple methods combining…

This research investigated the effects of two contrasting pre-k curricula, relative to practice as usual, on subsequent academic achievement. One curriculum had a strong literacy focus, the other was a less didactic "developmentally appropriate" curriculum that allowed children to have more influence on classroom activities. The purpose…

The purpose of this study is to compare the efficacy of three different approaches to professional development in Earth science education: preparing teachers to "adopt" expert-"design" curricula; preparing teachers to use a principled approach to design curricula; and preparing teachers to use a principled approach to "adapt" curricula. The claims…

The purpose of this study is to contribute to the existing literature on the foreign language learning of students with LLDs by conducting a comprehensive investigation of the performance of three students in middle school foreign language classes in a suburban school district in southwestern Pennsylvania. More specifically, this study documents…

This study explores the impact of an alternative teacher preparation program development from the "inside out" or through the voices of second career teachers, known as "Career Switchers," at a mid-size state university. The major objective of this study was to probe into their perceptions to inform program development with reporting framed in…
