This article presents the development and testing of a content-based video exchange model as a motivating means to introduce lower secondary English learners to English as the language of science. The central goal was that students reach the required curricular content knowledge despite learning some of the content in a foreign language. The model…

A variety of factors have converged in the last decade to focus attention on the need for more rigorous designs of professional development (PD). Teacher development is increasingly viewed as one of the primary levers for improving teaching quality and ultimately student achievement. The authors present data from the Teacher Knowledge Assessment…

This study investigated the effect on children's science understanding of Internet-based instruction in which children from around the world in grades 4 to 8 observed the Moon for several weeks and then shared their lunar data internationally to find global patterns in the Moon's behavior. Students in two American and one Australian class took the…

With just a few materials, building a paper model of the International Space Station (ISS) can become an excellent group, troop, or class project. This publication contains a brief overview of the ISS, its parts, the science that occurs on board, instructions, and extensions for an interdisciplinary technology experience. Discover more about the…

The objective of the present study was to develop a scale that is appropriate for use internationally to measure affective, behavioral, and cognitive dimensions of student engagement. Psychometric properties of this scale were examined with data of 3,420 students (7th, 8th, and 9th grade) from 12 countries (Austria, Canada, China, Cyprus, Estonia,…

Background: A key learning outcome in problem-solving domains is the development of procedural flexibility, where learners know multiple procedures and use them appropriately to solve a range of problems (e.g., Verschaffel, Luwel, Torbeyns, & Van Dooren, 2009). However, students often fail to become flexible problem solvers in mathematics. To…

This study is an evaluation of "Exploring Motion and Forces: Speed, Acceleration, and Friction" ("M&F") developed by ARIES of the Harvard-Smithsonian Center for Astrophysics (2001). Although "M&F" has been used in many schools and field-tested, it has never been evaluated in rigorous experimental or…

Background: School-based study recruitment efforts are both time consuming and challenging. This paper highlights the recruitment strategies employed by the national, multisite Trial of Activity for Adolescent Girls (TAAG), a study designed to measure the effectiveness of an intervention to reduce the decline of physical activity levels among…

History is an important but often overlooked content area for all students in this current era of accountability. Yet instruction in history can help students become problem solvers and learn to make interpretations from multiple perspectives. This article reports the results of a pilot study examining history learning across three groups of…

This paper describes an intervention at the 8th grade level where university mathematics researchers presented a series of lessons on introductory concepts in probability and statistics. Pre- and post-tests, and interviews were conducted to examine whether or not students at this grade level can understand these concepts. Students showed a…

Serious reading problems exist among middle school learners as evidenced by declining national reading scores and increased dropout rates. In response to the No Child Left Behind (NCLB) expectations in reading, several experts have promoted a scripted repeated reading strategy such as readers' theater as a possible approach to improving student…

As other countries vigorously promote rapid advancement in science, optimizing the participation of all students in the United States in science is imperative. This study focused on African American students and examined their science achievement in relation to Black Cultural Ethos (BCE), a construct rooted in psychology. Via qualitative and…

In 2001, the U.S. Department of Education and the Ministry of Education in China entered into a bilateral partnership to develop a technology-driven approach to foreign language learning that integrated gaming, immersion, voice recognition, problem-based learning tasks, and other features that made it a significant research and development pilot…
