In the fall of 1999, Science and Children extended an invitation to K–8 teachers to participate in a national study (Barman, Barman, Berglund, and Goldston, 1999). The main focus of this study was to examine students’ ideas about animals. This study received an overwhelming response from K–8 teachers throughout the United States. This article will briefly explain how the data was collected, present the findings, and discuss the implications of these results for K–8 science teaching.
