Foreword At the request of many teachers, principals, supervisors, county superintendents, and the State Course of Study Com- mittee, A Brief Guide to the Teaching of Science in the Sec- ondary Schools, Bulletin No. 8, has been prepared. Volumes dealing with the teaching of English, mathematics, and social studies have already been issued. This bulletin completes the series of guides for the four basic fields. The four fields of English, mathematics, science, and social studies represent a large portion of the secondary curriculum, particularly of that part dealing with general education. The degree to which these basic fields meet the needs of society and of the individual will determine, in a large measure, whether or not as a nation we shall meet our world responsibilities of the future. The material in this bulletin varies somewhat from that found in the usual guide to science teaching. It does not present a syllabus or outline of what is to be taught. In many instances a determination of just what is to be taught can be wisely reached only after the teacher becomes familiar with the community and its possibilities. The group which compiled the suggestions contained in this bulletin considered it more important to point out ways of increasing the effectiveness of teaching than to repeat specific instructions such as those contained in the pub- lisher's teachers manual. The bulletin is written to furnish ideas that will enliven and enrich teaching rather than to give specific instruction for presenting topics or units. The suggestions in the bulletin in- clude some by outstanding authors, but most of them are drawn from the rich teaching experiences of the participants and con- sultants in the workshop group. The list of suggestions is not thought to be exhaustive. Many teachers will know of others as effective as the ones in this book. Each teacher is urged to consider the suggestions carefully, to choose those which seem applicable to his teaching situation, and to add to them as imagination and initiative suggest the additional activities. The participants in the workshop included Miss Eloise Briz- zard, John Gorrie Junior High School, Jacksonville; Edward Brunk, Supervisor of Instruction, Apalachicola; Miss Kathryn
