A textbook that offers the choice of something different to the professor whois interested in the pedagogy of chemistry is now available. The hook successfully meets the author's objectives of showing "that chemistry is alive, involved, and relevant to everyone's life, that it makes perfectly good sense, and that chemical knowledge is created by real people in areal world." Many of us who teach chemistry are feeling the pressures of the larger classes as a greater numher of students reeister for colleee chemistrv. Manv secondary school preparation in science and mathematics often because they are now technically inclined and have delayed an experience in the natural sciences until required to complete a distribution requirement in their college curriculum. "Chemistry Explained" has been written primarily for the one-semester or two-quarter course. There is sufficient material that selectivity will he required for the shorter courses. The shortest courses will probably not include the last five chapters: Chapter 14, "Materials, Part One: Some Natural Materials;" Chapter 15, "Organic Compounds and Their Reactions:" Chanter 16. "Materials.

represent approximately one hundred pages or twenty percent of the text. A minimum of supplementary material in addition to the above chapters would be required for an academic year offering. The author has been very helpful with suggestions far the longer course and suggests that student, interests be allowed to dictate the selections. This reviewer believes that the text has sufficient

outstanding features that many teachers will consider the text for students who wish to he science majors but who have not had adequate secondary school preparation in mathematics and the sciences in addition t o the "liberal arts" students for which it was primarily written. The course for the unprepared science majors would probably require a weekly "problems session" using a supplementarv list of oroblems and he accomoanied by a sirang laboratory syllabus &sing "discovery" and quantitative experiences. The text indudes a minimum number of problems but is not deficient in the types of problems included and explained. The first thirteen chapters include aspects of general chemistry, nuclear, and physical chemistry. The text, therefore, presents a complete mini-curriculum in chemistry. The author has described his approach in The Preface: "Ideally, if the textbook could satisfactorily fulfill the role of explaining-of instilling understanding, rather than compiling facts-the instructor might not have to spend so much time paraphrasing the text in lectures and explaining again to individuals in the office. Instead. he or she would be

act as a facilitator, a human resource, rather than as a translator and rehasher of the material that the student has already read."To successfully implement this approach the author has kept the organizational thread of the text chemical, rather than societal or applied, although the text discusses as many if not more applications than the average textbook. A nondogmatic attitude and a light conversational writing style has been adopted. This style created a doubt the first time that I read the text. Upon rereading the text, and having my wife, a nonscientist, read oortions. the imoression became one of "it

The book is written as if the reader is pragressing sequentially through its pages. It is, in fact, similar to a PSI (Personalized System of Instruction) teachine method.

Although different in style, which may require a second or third reading to overcome habits formed in reviewing texts, "Chemistry Explained" offers too many possibilities for student instruction to ignore the text beesuse it is different.
