Volume Three of the three-volume experimental program in general science attempts to provide preparation for the new approaches in biology, chemistry, and physics and to give those who will not continue in science a realistic way of understanding themselves, the world, and the role of science in society. Chapters on embryology, the body systems,…

The core portion of this trial unit prepared by the Australian Science Education Project provides an introduction to the structure of the earth, volcanic activity, the types of igneous rocks, earthquakes, and seismology, with an emphasis on the techniques of inference used to relate external evidence to internal structure. The optional activities…

Content, readability, safety aspects, appearance, technique, effectiveness of experiments, enrichment exercises, teacher aids, and special features of 12 physics laboratory manuals are reported and compared. (JN)

This column generally relates errors which have been discovered in textbooks. The error discussed in this issue is the prevalence of erroneous ideas in organic chemistry textbooks, related to the chemistry of sodium borohydride. (Author/SA)

Analyzes nine high school biology manuals to determine how well they promote the basic and integrated science process skills that are involved in scientific inquiry. Results indicate that the manuals seldom enable students to use their knowledge and experience to pose questions, solve problems, investigate natural phenomena, or construct answers…

Professors have long assigned to their students works of which they were the author. The practice ranges from assigning commercially published textbooks they have written to having students buy a volume they have written and published or course packs made up of their own materials they have photocopied. Not only individual professors, but also…

This publication provides twelve model spacecraft construction plans for use by secondary school teachers in industrial arts classes. These models were adopted and developed from plans supplied by the National Aeronautics and Space Administration and are representative selections from the many spacecraft used in space exploration programs. Some…

The illustrated manual is designed for student use in learning home dishwashing and in preparing for a job as a dishwashing-machine operator. The six parts cover vocabulary, hand dishwashing, machine dishwashing, problems and checks, special treatment of various dishes, and safety tips. The vocabulary section presents an objective and defines 22…

Project Marine Ecology Research (MER) is an ecological curriculum designed to involve secondary students in the study of the marine biome. The background material and learning activities concern the study of the San Francisco Bay Area. The guide is divided into two major parts. In the first part, a history of the Bay Area is given. It includes the…

Reports on the development of a sample course in modern mathematics for elementary teachers. The approach to the course was based on three methodological principles--(1) that emphasis should be placed on mathematics as an organization of (experimental and other) information and not primarily as a deductive system, (2) that it is important to use…

This technical manual for the use of language laboratories includes information on the following topics: (1) types of laboratories, (2) the tape, (3) the tape recorder, (4) other basic technical equipment, (5) the audio-active laboratory, the audio-active-compare laboratory, and an evaluation of the two, (6) possibilities for expanded use, (7)…

A preliminary version of this trial draft of a unit prepared for Australian secondary science students was previously announced as ED 049 931 under the short title of "Messengers." The teachers' guide is an overprinted version of the students' booklet, and lists objectives for each section of the materials, indicates possible teaching…

An alternative method of bacterial spore staining using malachite green is described. This technique is designed to save time and expense by a less messy procedure. Advantages and adaptations of the technique are also given. (MR)
