David Evans to Lead U.S.Science Teachers Group

摘要

David Evans has never taught science at the precollege level. Nor has he carried out research on how to improve science teaching and learning. But the new executive director of the National Science Teachers Association says he sees value in bringing a fresh eye to the rapidly changing field."Information is much more accessible, and people can get it in a variety of new ways," says Evans, who last week took the helm at the 60,000-member society, based in Arlington, Virginia.
