An inquiry goal for science education allows epistemic goals that focus on how we know what we know and why we believe it to be of better-quality than any other competing beliefs (Duschl Ellenbogen, 2002). A major deficiency of the current science educational practice is that teachers promote nothing at all, or little, to explain the rationality of science and to explain scientific thinking in their classrooms (Osborne Wellington, 2001). Because scientific knowledge is presented in such idealized form “as a pure abstract method of proceeding, decontextualized from the choices, values, and institutions which motivate and constrain our proceedings” (Lemke, 2002, p. 1), the needs emerge to change the current science teaching practice to accomplish much more than simply detailing what we know (Minstrell Van Zee, 2000; National Research Council, 2000). Educators argue that students need to be involved in forms of cla
