Presented are laboratory studies focusing on blood cells and the complete scheme of blood coagulation. Formed is the basis for the following types of laboratory operations: (1) distinguishing the morphology of normal and abnormal blood cells; (2) measuring the concentrations or number of blood cells; (3) measuring concentration and detecting…

PART I OF THIS REPORT IS AN INTRODUCTION EXPLAINING THE CONFERENCE. PART II CONTAINS EXPANDED COURSE OUTLINES OF PHYSICS COURSES FOR NONSCIENCE MAJORS THAT WERE PRESENTED TO THE GROUP BY SEVEN PARTICIPATING…

Research evidence on the effectiveness of various methods of teaching at the university level are reviewed. Evidence is presented in the following areas: the effect of class size; large group instruction techniques; individualized learning, independent study, and programmed instruction; lecturing versus other methods; and laboratory teaching. The…

This handbook, written specially for the San Diego Public School System, contains detailed discussions on first aid, good laboratory practices, safety in the laboratory, and laws regulating the care and use of animals. The section on "First Aid" presents, in addition to standard first aid information, a discussion of first-aid kits for…

This math lab activities booklet accompanies a teacher's management guide and a set of five booklets which comprise the basic curriculum for "Mathematics Laboratories for Disadvantaged Students," a nationally validated Title III ESEA project. The materials in this bulletin are designed to serve as the core of the laboratory curriculum.…

This publication reviews the mathematical laboratory from three perspectives: a practical view of laboratories in operation, a review of related research, and a view of current laboratory evaluation procedures. After a discussion of definitions, types, and purposes of math labs, the first paper concentrates on their historical development in…

The "Flash Lab" method of teaching the elementary fundamentals of drawing, a system based on the psychology of perception, the behavioral sciences, and the biological sciences, was developed to help correct common errors which beginning students make, such as inability to generalize, lack of proportional relationships, misjudgement due to depth,…

To identify functional competencies needed by instructors who teach in contemporary industrial arts programs, 75 functional competencies were incorporated into a questionnaire sent to industrial arts educators and supervisors throughout the United States, Canada, and the District of Columbia. From the 438 responses, representing 78.2 percent of…

Discusses some difficulties presented by the use of clock reactions with large numbers of students in illustrating the determination of rate laws and the deduction of a mechanism. Suggests the videotaping of a clock reaction without narration to be used with students in stages so that observations can be recorded. (TW)

Describes how to construct a simple photometer. Outlines experiments in which this device can be used to demonstrate basic electronic principles, the use of Beer's Law to determine the concentration of an analyte in solution, and the effect of molar absorptivity on the sensitivity of photometric procedures. (TW)

Describes a laboratory activity that is adaptable to several levels of biology students. Discusses methods for obtaining hellgrammites, performing the experiment, and analyzing the data. Includes sample charts and graphs. (CW)

Described is a study designed to introduce students to the behavior of common invertebrate animals, and to use of the chi-square statistical technique. Discusses activities with snails, pill bugs, and mealworms. Provides an abbreviated chi-square table and instructions for performing the experiments and statistical tests. (CW)

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Describes a crystallography experiment using both diffraction-angle and diffraction-intensity information to determine the lattice constant and a lattice independent molecular parameter, while still employing standard X-ray powder diffraction techniques. Details the method, experimental details, and analysis for this activity. (CW)

Describes a circuit by which capacitance and the dielectric constant can be measured. Shows the circuit diagram and the method to calculate these constants. (YP)
