A laboratory study was performed with four levels of discovery and two levels on an overlearning factor. An improved experimental paradigm was chosen so as to avoid a number of confusions which have obscured previous research. An operational definition was developed for discovery and guided discovery and discovery teaching, and inquiry learning.…

The author views the primary purpose of the modern engineering laboratory as teaching the student how to experiment. An attempt is made to update the engineering laboratory and make it generally meaningful for all students, whether headed for graduate school or an industrial job. The intent is to broaden the experimental picture so that students…

The publication presents outlines of some of the difficult experiments suggested in the chemistry syllabus for the Certificate of Sixth Year Studies in Scotland. The experiments included in the publication form a small part of the total experiments suggested in the syllabus. Simple experiments, the details of which are available in textbooks, are…

This manual is designed for use in the laboratory phase of courses dealing with microbial aspects of pollution. It attempts to cover the subject area broadly in four major categories: (1) microorganisms in clean and polluted waters, (2) carbonaceous pollutants, (3) nitrogen, phosphorus, iron, and sulfur as pollutants, and (4) sanitary…

THE EFFECTS OF SEVERAL STYLES OF SUPERVISION UPON THE PERFORMANCE OF INDIVIDUALS WERE EXPLORED IN A LABORATORY SETTING IN WHICH SELECTED ASPECTS OF SUPERVISION WERE EXPERIMENTALLY MANIPULATED. PARALLELING THE WORK SITUATION, THE EXPERIMENTAL SETTING INVOLVED A CHOICE OF TWO ACTIVITIES, EACH OF WHICH WAS REINFORCED. THE ROLE OF SUPERVISION WAS TO…

Describes a heat transfer experiment that demonstrates kinetic behavior using measurements of the rates of cooling and warming of liquids. (MLH)

Describes a college-level course on winemaking and brewing offered to both the academic and the non-academic community. Discusses fermentation and the processing of wine and beer. (MLH)

Describes an experiment that demonstrates the following principles and reactions: amphoterism, oxidation-reduction, equilibrium dependence on pH, solubility, and polymerization. The experiment involves the oxidation of chromium and the precipitation of a chromate salt. (MLH)

Describes an undergraduate physical chemistry experiment in which the kinetics of the various reactions involved in the flash photolysis of water are analyzed on a computer. (MLH)

Describes a straight-forward method of measuring the absolute value of the conductance of an electrolyte solution using direct current and applying Ohm's law. (MLH)

Suggests classroom projects for investigating the diversity of insects. (LS)

Describes how the principles of reactor analysis can be used to study human circulation. (MLH)

Describes an undergraduate experiment that provides instruction in nuclear magnetic resonance (NMR) spectroscopy, reaction rates, and the application of mathematical procedures. (MLH)

Describes a natural-products experiment involving steam distillation, solvent extraction, and spectroscopic identification. (MLH)
