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 this study was to determine if the effects of an instructional program would affect the performance of general education chemistry students with respect to objectives related to the methods of science and the degree to which they are effective in simultaneously teaching the descriptive chemistry of certain elements. The mode of…

This course guide is designed to aid chemistry instructors in teaching the skills and knowledge needed by those students planning to take junior college chemistry and is composed of 11 terminal performance objectives, with intermediate performance objectives and sample criterion measures. Suggestions for related laboratory activities are also…

This study concentrated on three problems dealing with academic backgrounds related to achievement in college freshman programs in chemistry. One problem was related to the high school science curriculum. The other problems involved the possibility of devising a prediction scheme based on a student's academic background, and the possibility of…

The bibliography is intended to provide a comprehensive source of information on the sampling and monitoring of particulates in flowing gas streams. It also includes methods of measurement which were initially applied to the measurement of dust in still atmospheres, but which either have been or may be used in the future for measurements in…

This report presents the procedures, results, and conclusions of a study to determine the characteristics of secondary school chemistry students who were successful in grasping a mathematical approach to learning chemical equilibrium. Subjects were eighty-nine students enrolled in chemistry at a rural-suburban high school; each student had…

The material presented in this three-volume manual is a summary of the history and experiences of the Huntington Computer Project, and the purpose of the manual is to assist high school teachers and other educators who wish to explore the uses of computers in high schools. The first volume contains an introductory section which gives the…

Described are the science syllabuses and texts for the science courses written to fulfill the aims of the new system of education in the state of New South Wales, Australia. The science course was developed in two stages: (1) A four year integrated science syllabus for grades 7-10, and (2) separate courses in physics, chemistry, and biology with…

This paper presents the rationale, structure, and specifications for a model program for the preparation of chemists, chemical engineers, and high school chemistry teachers. The model (an application of systems technology to program development in higher education) is based on the structure provided by the Georgia Educational Model Specifications…

This unit emphasizes concept-learning through the discovery approach and child-centered activities. "Discovering Matter" is treated in the kindergarten, "Matter Around Us" in grade 1, "Changes in Matter" in grade 4 and "Atoms and Molecules" in grade 6. The unit for each grade contains (1) understandings to…

This autoinstructional unit deals with the phenomena of regularity in chemical behavior. The prerequisites suggested are two other autoinstructional lessons (Experiments 1 and 2) identified in the Del Mod System as SE 018 020 and SE 018 023. The equipment needed is listed and 45 minutes is the suggested time allotment. The Student Guide includes…

This course of instruction in advanced chemistry is intended for the student ready for first-year college chemistry. Presented is an in-depth review with theory and mathematics being stressed in the study of concepts involving atomic structure, bonding, states of matter, molar relationships in equations, and properties of solutions. It is…

Reported is a study to examine the relative effectiveness of high indirect (I/D) ratio teaching to low I/D ratio teaching in increasing student's knowledge in chemistry and general science. Four high school chemistry teachers and four general science teachers of grades eight and nine in junior high school with their respective classes were…

A brief overview of CHEMEX--a problem-solving, tutorial style computer-assisted instructional course--is provided and sample problems are offered. In CHEMEX, students receive problems in advance and attempt to solve them before moving through the computer program, which assists them in overcoming difficulties and serves as a review mechanism.…

This booklet presents 18 experiments in the chemistry of food, suitable for elementary and secondary school science classes. Experiments deal with an analysis of milk, determinations of the amounts of sulfur dioxide, iron, and fat in foods, and the concentration of vitamin C in fruit juice and iodine in salt. Tests are provided for fats,…
