Abstract

I have modified small-scale, one-pot reactions reported in the literature to a guided inquiry approach. These reactions involve aqueous ionic equilibria centered around three different cations. Each cation has its own set of self-contained reactions that occur in sequence in just one test tube, on a small scale. In this modification, students are given an initial handout and asked to complete a short, attention-getting exercise. They must continue to work on logical, short exercises given to them one at a time, in handout format, in order to complete the entire laboratory exercise. The inquiry-based approach is intended to increase students' comprehension of what they're doing in the laboratory and why they're doing it. The exercise is suitable for first-year college-level general chemistry students.

  A survey of high school chemistry teachers in the U.S. indicated that 45.5% of these teachers are not using inquiry methods in their classroom. Perhaps they would be persuaded by student insights into learning with inquiry. This article describes the ...
