The authors engage students in inquiry-based learning by presenting laboratory exercises as mini-journal articles that mirror the format of a scientific journal article, including a title, authors, abstract, introduction, materials and methods, results, discussion, and citations. Students develop and carry out their follow-up investigation, then present their findings in the form of their own mini-journal. Mini-journals replace traditional cookbook laboratories with a format that more directly encourages scientific practice. (Contains 3 tables and 2 figures.)
