Regular readers of The Science Teacher (TST) may have noticed a lot of articles on scientific inquiry and notable among TST articles on inquiry are Bell and colleagues' “Simplifying Inquiry Instruction” and McComas’s “Laboratory Instruction in the Service of Science Teaching and Learning.” Judging by how often these articles are cited in the inquiry literature, Bell et al. (2005) and McComas (2005) seem to have provided a useful model for thinking about inquiry. Hopefully, this issue of TST will add to this literature.
