“…Students in the United States are outperformed on science achievement tests by their counterparts in many developed countries, particularly those along the Pacific Rim (Gallagher, 1993;Linn, Lewis, Tsuchida, & Songer, 2000) and show diminishing interest in science as they move through the educational system from grade school and middle school (Greenfield, 1996;Jovanovic & King, 1998;Simpson & Oliver, 1990) through high school and college (Bazler, Spokane, Ballard, & Fugate, 1993;Simpson & Oliver, 1990). The lack of involvement in science among United States students has led to a shortage of native born scientists and the concern that the United States may lose its competitive edge in science and technology (Collins, 1997;Gallagher, Manis et al, 1989), forms of bias in science educational materials and texts (Guzzetti & Williams, 1996;Potter & Rosser, 1992), and teacher attitudes and differential treatment of boys and girls in the classroom (American Institutes for Research, 1998;Guzzetti & Williams, 1996;Kahle et al, 1993;Manis et al, 1989).…”
