The Precipitating Change Project was a 5-year development, implementation, and research study of an innovative 4-week middle school curricular unit in computational weather forecasting that integrates students' learning and use of meteorology and computational thinking (CT) concepts and practices. The project produced a list of CT skills and…

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…

This study investigated urban eighth-grade students' knowledge of energy resources and associated issues including energy acquisition, energy generation, storage and transport, and energy consumption and conservation. A 39 multiple-choice-item energy resources knowledge assessment was completed by 1043 eighth-grade students in urban schools in two…

As more primary and secondary students worldwide seek after-school tutoring in academic subjects, concerns are being raised about whether after-school tutoring can raise average test scores without widening the variability in student performance, and whether students of certain ability levels may benefit more than others from after-school…

We believe that students should have opportunities--early and often--to learn about science and math activities in fun and recreational ways. As a result, we try to provide many science enrichment activities to the surrounding community. In doing so, we hope to inspire young students to become future scientists and mathematicians. Here we describe…

In an experimental study (N = 209), the authors compared the effects of exposure to typical middle-school written science content when presented in the context of the scientific discovery narrative and when presented in a more traditional nonnarrative format on 7th and 8th grade students in the United States. The development of texts was…

Research over the past fifteen years has investigated and developed online science inquiry environments to support students engaging in authentic scientific inquiry practices. This research has focused on developing activity structures and tools to scaffold students in engaging in different aspects of these practices, but relatively little of this…

Despite being known as the land of opportunity, the United States is far from equitable when it comes to the mathematics that students have the opportunity to learn. In this article, the authors explore the extent to which students in different schools and districts have an equal opportunity to learn mathematics. Specifically, they discuss…

"If someone were traveling to our area for the first time during this time of year, what would you tell them to bring to wear? Why?" This question was used to engage students in a guided-inquiry unit about how climate differs from weather. In this lesson, students explored local and national data sets to give "travelers" advice…

Despite being the inventing country of the Internet, the US is not satisfied with its current state in Internet speed and broadband adoption. Although, more students, teachers and researchers in the US use Internet than any other country in the world, it is not satisfactory for the US educators and legislators to maintain US competitiveness in the…

Almost every time the results of an international test of student achievement are released to the world, the reaction among the American public and policymakers is like that of a parent whose child just brought home a disappointing report card. Elected officials and academic experts question where U.S. students fell short: Was it their curriculum,…

Teaching and assessing both content and 21st century skills are critical for student academic success and success in the workplace. In the "Highlights from TIMSS 2007" report, released in December of 2008 by the National Center for Education Statistics, Institute of Education Sciences, data shows that while 4th- and 8th-grade students in…

The Trends in International Mathematics and Science Study (TIMSS) Video Study explored instructional practices in the United States (US) in comparison with other countries that ranked higher on the 1999 TIMSS assessment, and revealed that 8th grade science teachers in the US emphasize activities over content during lessons (Roth et al.…

This study examined science textbooks over time to better understand the "science content" expectations that the U.S. educational system deems appropriate for 8th and 9th grade science students. The study attempted to answer the questions: (1) What specific science content has been presented via the textbook from 1952 to 2008? (2) Within…

Using the Trends in International Mathematics and Science (TIMSS) video study, the authors compare science teaching practices in the United States and in four other countries that outperformed the United States: Australia, the Czech Republic, Japan, and the Netherlands. Their observations of videotapes from 100 8th-grade science lessons in each…
