This study investigated the feasibility of using computer-simulated experiments in high school physics and chemistry. Fifteen sections of students enrolled in high school physics and chemistry were randomly divided into experimental and control groups. A series of 10 experiments was done by use of computer simulation in the experimental group;…

The purpose of the study was to establish a list of acceptable terminal behavioral objectives for the nonmajor general biology laboratory as perceived by each instructor in every institution for higher education in the state of Missouri who is responsible for planning, organizing, operating, and evaluating that course. It was further the purpose…

This combined teaching and study guide is for use by students and teachers in post secondary programs for nucleonics technicians. It was developed by the author under the National Defense Education Act, Title VIII. The unit headings are: (1) Physics of the Atom, (2) Natural Radioactivity and Atomic Energy, (3) Induced Radioactivity and Atomic…

In this study, a pencil paper performance test (PPPT) was developed and administered to an experimental group of 46 students and a control group of 48 students to determine: (1) the difference between laboratory performance and the successful completion of a laboratory course in electricity, (2) the relationship between laboratory performance as…

Described are the student's text and teacher's guide of the first module for secondary schools prepared for the Interdisciplinary Approaches to Chemistry (IAC) project. The main approach to teaching is to present chemistry as a dynamic field of knowledge concerning phenomena in the daily life of every individual. This module, the first in a series…

Laboratory experiments are presented in these first three manuals of a six-volume series for use at the 12- to 16-year-old, or British CSE, level. On the subject of food tests, 17 exercises are prepared in connection with Biuret reactions, starch and emulsion tests, Millon's and Benedict's reagents, reagent sensitivity, and calorific values and…

A MANUAL WAS PRODUCED CONTAINING LABORATORY PROCEDURES FOR A ONE-SEMESTER COURSE IN ELEMENTARY QUANTITATIVE CHEMISTRY ON A COLLEGE FRESHMAN LEVEL. MATERIALS AND TOPICS WERE EXAMINED AND CHOSEN AS TO DESIRABILITY, PRACTICALITY, AND EDUCATIONAL VALUE. OPTIONAL EXPERIMENTS WERE ALSO INCLUDED. THE LABORATORY PROCEDURES WERE TESTED ON SOPHOMORES AND ON…

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)

Describes a laboratory experiment in which the students prepare an antichap lipstick from basic ingredients and demonstrate solubility relationships between these ingredients and water. (MLH)

The pedagogy and an extensive listing of topics suitable for large scale demonstrations are provided. (CP)

Describes two experimental procedures and the reactions suitable for teaching the principle that catalysts do not affect the position of equilibrium. (GS)

Describes an activity which incorporates topographic map interpretation, soils analysis, hydrogeology, and local geology in a five-week series of exercises for an introductory college earth science class. (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)

Explains an error analysis procedure using the computer which requires no previous student experience with the computer. (CP)

Reported here is a convenient alternative for determining the enantiomeric purity of student resolved alpha-phenylethyl amine using a chiral lanthanide shift reagent. (BB)
