Describes laboratory activities which relate the mass, volume, density, and radii of atoms through the assumption that the smallest unit of matter is a cubic box containing one atom. From calculations based on macroscopic materials, the author feels that the concept of an atom may be better developed. (CP)

Data compiled over seven years present evidence that small-group or "cluster" carrels are successfully utilized by medical students in a learning resource center and should be considered to be an efficient method of managing space, software, and hardware. Three management concepts are reported. (Author/LBH)

Investigates whether chemistry laboratory skills are commonly developed in secondary schools and whether college professors and high school teachers agree that students still demonstrate these skills in first-term college chemistry labs. One hundred and four chemistry teachers and 298 college professors participated in this study. (HM)

Described is a sampling board that has been used in an introductory general ecology course that is inexpensive to construct and that effectively illustrates the principles of vegetation sampling. (Author/BB)

This is a course required of all sophomores at the Colorado School of Mines. It introduces students to the principles of measurement theory at a higher level than is common in an elementary physics lab. The subjects of error analysis, graphing, least-squares analysis, experimental design, measuring instruments, and report writing are covered.…

Selection of tool steels for particular applications, different classifications and their properties, and methods of heat treating and machining the steel are described. (MF)

Describes some of the instructional methods tried, the problems encountered, and the philosophies involved concerning individualized instruction in a community college. The two semester introductory biology course emphasizes the open laboratroy concept, with individualized instructional modules prepared for laboratory experiments. (HM)

The need for and development of the Miller System for filing tapes and corresponding information are discussed. Boston University's Geddes Language Center developed a distributable catalog of source materials that lists holdings by author and title of work within each language division. (SW)

The Health Careers Program for handicapped students at Francis Lewis High School in New York is described. The science laboratory design, visits to local hospitals and medical labs, and teaching techniques are highlighted. (MDR)

Describes a two-year high school chemistry course for girls that includes visits to local industries, the study of their chemical processes, and work in their laboratories. (GA)

Describes the positive response to and the success of a course, called "Science in Action," that was offered to elementary school children on Saturdays, and took place in college laboratories of physical science and biology. (GA)

Describes a chemistry course designed for the general student at Pampa Senior High School, Pampa, Texas. It presents the fundamental concepts in chemistry in a nonmathematical context; contains many options in the form of minicourses; and permits the student to pace himself. (HM)

Discusses how a science teacher should help visually impaired students and how he or she can cope with their problems. Also discusses what a science teacher can provide for a visually impaired student's safety and how this student should be helped to do lab activities. (HM)

Examines the learning laboratory at Illinois Central College. Proposes that the learning center of the future must assume a new administrative position as an independent unit, develop new services for the faculty which will, in turn, benefit the student, as well as engage in research relevant to instruction. (TP)

Lecture and laboratory topics of a one-quarter, undergraduate course designed to introduce students to chemical principles and phenomena involving the automobile are described. (CP)
