How do your students' measurement skills measure up by today's standards? While many science teachers in the United States use the metric system in their classrooms, many students still haven't realized that the metric system has uses outside the science classroom. This issue is filled with interesting ideas from other teachers for helping your students master metric measurement.

Professional Development

The U.S. Department of Education recently launched "Teachers Ask the Secretary," a new feature of its website (http://www.ed.gov). According to U.S. Education Secretary Margaret Spellings, "This easy-to-use page will help teachers learn answers on a wide range of subjects: teacher quality, professional development, state academic standards, and more. We will share best practices and success stories under the No Child Left Behind Act. And we will listen to your concerns." To ask a question or to view what other teachers are asking, go directly to http://www.ed.gov/teachersask.

Global Science Teaching

Americans and Chinese Differ in Their World View—Literally

"Richard E. Nisbett of the University of Michigan and his colleagues conducted a series of experiments in which Chinese and American students were shown a number of images, each depicting a single subject against a realistic and complex background. The participants—who wore an eye-movement tracker during the tests—were then shown pictures containing the same subjects on either old or new backgrounds and asked to judge whether they had seen the subjects before." This article from the August 23 issue of Scientific American examines the results of these experiments and their bearing on differences in socialization and teaching.
