Many students today do not spend their free time playing and exploring outdoors, so they may not be developing the strong connections to the world around them that are critical in helping them become stewards of the environment. Read this issue to see how some of your colleagues are encouraging their students to care about the Earth and inspiring their interest in how they can help preserve its many delicate webs of life.

Professional Development

Engaging the Budding Scientist

With an increased emphasis on testing science achievement comes a corresponding need to make science interesting and exciting to students. The authors in the December 2006 issue of Educational Leadership spotlight science education, discussing the demand for more rigorous science teaching in classrooms, the professional development science teachers require, and the need to share best practices internationally.

Global Science Teaching

Happy Birthday, Darwin! Are you and your students aware that Charles Darwin, the famous naturalist who provided the first coherent theory of evolution by means of natural selection, was an indifferent student and slow learner who preferred to spend hours watching birds, examining plants, and collecting seashells and insects? Join educators worldwide in celebrating Darwin Day on February 12—the anniversary of Darwin’s birthday—and let his story inspire your students to study science. For a detailed description of Darwin’s life and work, access http://www.aboutdarwin.com. This website has an extensive database of links to education websites related to Darwin and his work. See also http://www.amnh.org/exhibitions/darwin, which offers an educators guide and links to evolution websites.
