Dudley Herron is a veteran chemical educator, whose contributions to this Journal are numerous and of high quality. He has had experience in teaching both secondary and tertiary chemistry, and The Chemistry Classroom is a distillation (pardon the obvious metaphor) of what he thinks teachers should know. Every effective teacher develops a style of teaching that is consistent with his or her own personality and experiences. Professor Herron sensibly recognizes that truth, and warns the reader that no model of teaching, even the vaunted and holy "Learning Cycle", is appropriate for every situation. The textbook is intended to convey some of the author's insights to less experienced or less perceptive colleagues, so that they can incorporate them into their own practice. Herron begins the text with brief descriptions of his most memorable students, types that any teacher will eventually encounter, and throughout the book uses examples from his own history to illustrate general principles of knowledge, teaching, and learning. I find his descriptions of the specific difficulties that students experience in learning and teachers have in assessing chemical concepts to be particularly valuable. Herron's recommended approaches to teaching are often described in terms of the stages intellectual growth elucidated by Jean Piaget, whose theories of knowledge and learning permeate the book. In that respect, there are similarities to Constructing Science, but the examples provided by Herron are nearly all from chemistry. All three of these textbooks provide profitable reading for any chemistry teacher interested in learning better to teach. Both Constructing Science and Teaching Secondary Science aim at the potential high school teacher, but tertiary instructors could profit by reading them. While it would certainly be useful for secondary school teachers, The Chemistry Classroom will appeal more than the other two books to college/university professors or graduate teaching assistants who would like to do a better job. I hope that many of them will read and use these books.
