Directions are given for the construction of a manometer to measure animal metabolism. Steps in an experiment to measure frog metabolism are specified. (DT)

Discusses the educational values of participating in science fairs, and outlines the procedure used at Saint Ursula Academy, Toledo, to interest each biology student in an individual investigation. (JR)

THE SPONTANEOUS BEHAVIOR OF A TEACHER AND HOW THIS BEHAVIOR AFFECTS LEARNING IN THE CLASSROOM WERE INVESTIGATED. INDEPENDENT VARIABLES IN THE STUDY WERE DIRECT TEACHER INFLUENCE, AND THE NATURE OF THE SPECIFIC LEARNING TASK. THE DEPENDENT VARIABLES WERE THE ACTUAL MEASURES OF LEARNING, INCLUDING AWARENESS OF FACTS, APPLICATION OF PRINCIPLES TO…

Reported is a study comparing two laboratory teaching methods used with a college level general physical science course. The criterion instruments used were: (1) Watson-Glaser Critical Thinking Appraisal; (2) The Sequential Test of Educational Progress; (3) Nelson-Denny Reading Test; (4) Welch Science Process Inventory; and (5) The Smith Appraisal…

This teachers' handbook outlines the philosophy of this program, the methods of teaching it, and the information needed to perform the investigations. The purpose of this program is to encourage students to identify an environmental area to work in and to provide them with the tools to investigate it. The program fosters the idea of unsupervised…

Tells of an experiment introducing the Montessori system (which is described), stressing individualized approach, in a junior high school. Good results were obtained with good and poor students. It is concluded that the system could be relevant for beginning English classes in other types of schools. (Text is in German.) (IFS/WGA)

Outlines an experimental procedure in which an iodine radioisotope is used to determine molar combining ratios of lead and silver with the iodine. Tables and graphs show the definitive results that should be attainable. (CP)

Provides an account of the way in which one small university has coped with limited funds and a small staff to provide laboratory activities for freshman physics courses. (CP)

The use of participatory lecture demonstrations in the classroom is described. Examples are given for the following topics: chromatography, chemical kinetics, balancing equations, the gas laws, kinetic molecular theory, Henry's law of gas solubility, electronic energy levels in atoms, and translational, vibrational, and rotational energies of…

Explains some experiments involving thermal methods of analysis for undergraduate chemistry laboratories. Some experiments are: (1) the determination of the density and degree of crystallinity of a polymer; and (2) the determination of the specific heat of a nonvolatile compound. (HM)
