High school biology teachers face many challenges as they teach evolution. State standards for evolution may provide support for sound evolution instruction. This study attempts to build upon previous work by investigating teachers' views of evolution standards and their evolution practices in a state where evolution standards have been…

This article describes a game designed to help Spanish high school students (grade 10, age 15-16) understand the periodic table. It combines some features of bingo and a puzzle in the same pedagogical game, making it an engaging approach for learning about this important teaching tool. Students are given a verbal clue -- the name of a chemical…

This study examined the similarities and differences among 171 Grade 7-12 science teachers from three different countries (54 U.S, 63 Bolivian, and 54 Turkish) with respect to their attitudes toward environmental education (EE) and instructional practices. The instrument employed explored how teachers' knowledge, instructional practices,…

Researchers, policymakers, business, and industry have indicated that the United States will experience a shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this shortage, one of which includes increasing the representation of girls and women in the…

The country's technological edge is receding, and the problem cannot be solved simply by flooding the workforce with more engineers and scientists. This comes as little surprise to administrators at the nation's community colleges. In 2007, the National Academy of Engineering, National Academy of Science, and the Institute of Medicine responded to…

This research investigated the similarities and differences between Korean and U.S. 9-12th grade science classrooms. The Reformed Teaching Observation Protocol was used to observe sixty-six classrooms (26 Korean and 40 U.S.) to examine the extent to which principles of constructivism framing both Korean and U.S. standards documents were observed.…

The purpose of this mixed-method study was to investigate the changes in high school students' perceptions of fluency with innovative technologies (IT) and the levels of students' scientific inquiry abilities as a result of engaging students in long-term scientific research projects focusing on community-based environmental issues. Over a span of…

Over the past three decades, the environmental justice movement has developed out of growing concern about unequal distribution of environmental harm and unequal access to environmental resources. The mainstream environmental movement has been criticized for failing to address adequately environmental justice issues. Several scholars have claimed…

English language learners (ELLs) often find themselves marginalized with respect to learning mathematics in U.S. schools due, in part, to language barriers and gaps in prerequisite math knowledge and skills. The goal of this study was to use Sen's (1980, 1992, 1999) capabilities approach model as a lens through which to analyze the relationship…

The purpose of this document is to provide background information that will be useful in interpreting the 2007 results from the Trends in International Mathematics and Science Study (TIMSS) by comparing its design, features, framework, and items with those of the U.S. National Assessment of Educational Progress and another international assessment…

A total of three hundred and fifteen (n = 315) gifted students from the 10th and 12th grade from the United States (n = 102), China (n = 125) and Germany (n = 88) were surveyed regarding their motivation and self-regulation in chemistry learning. A 3 x 2 x 2 MANOVA revealed "nation" as having the largest major effect on these variables.…

In this paper, the authors argue that chemical knowledge in the classroom will be enriched by the application of characterizations of models drawn from a range of disciplinary backgrounds. This discussion highlights two important issues relating to chemical knowledge in the classroom: (1) the status of chemical knowledge in the classroom,…
