This introduction to dynamic systems is intended for freshman and sophomore students in engineering, physical science, or social science. Material has been class tested and has led to increased student interest in further work in systems analysis and operations research. Notes are written for the student and are self-contained. Material can be…

A digital computer program, STAGEF, designed for use with the distillation experiments in a typical undergraduate Chemical Engineering laboratory in Unit Operations is explained. The program enables the student to determine the rate of liquid overflow and vapor boil-up which leaves each tray within the distillation column. The student may also…

This is one in a series of SMSG supplementary and enrichment pamphlets for high school students. This series is designed to make material for the study of topics of special interest to students readily accessible in classroom quantity. Topics covered include the law of decay, relative rate of change, and a general solution. (MP)

REPORTED IS A STUDY CONDUCTED TO DETERMINE THE RELATIVE LEVELS OF UNDERSTANDING OF CERTAIN FORCE CONCEPTS ACHIEVED BY PUPILS IN GRADES 2-6. EVALUATIONS WERE MADE BY MEANS OF PENCIL-AND-PAPER MULTIPLE-CHOICE TYPE TESTS, ONE FOR EACH LEVEL OF UNDERSTANDING--(1) KNOWLEDGE, (2) COMPREHENSION, AND (3) APPLICATION. SUB-PROBLEMS OF THE STUDY WERE (1) TO…

The identification of information elements can provide an important tool for the systematic development of an information system design. A state-of-the-art survey reveals mounting recognition and interest in the problem, a considerable history of prior efforts, but no well-defined methodology. A study in the context of a national information…

The Institution of Electrical Engineers conducted a study in the United Kingdom and the United States to determine the need for their new publication "Current Papers in Physics (CPP)," and its usefulness to the physics community. Questionnaires were used to (1) recruit panel members to test reader reaction to the publication over a…

Investigated were the effects of a carefully sequenced program of integrated media on achievement and affective responses of students in a multi-media systems approach to Harvard Project Physics. Five Harvard Project teacher field consultants were selected to teach the multi-media package, and five others were selected as comparison teachers to…

Presented are a suggested program and the course outlines for the pregraduate preparation of research mathematicians. The program set forth is designed for the first four years of a sequence of formal course study leading to the Ph.D. in a total of seven years. The proposed program of pre-graduate mathematical studies falls into two parts:…

This second volume, a compilation of reprints of experimental notes in physics, was prepared by the American Association of Physics Teachers (AAPT) Committee on Apparatus and by the AAPT Executive Office in response to requests received by the Association for a completely new edition. The goal of the Committee was to provide a selection of…

This study, conducted at Northeast Catholic High School for Boys in Philadelphia, was designed to determine if a significant difference existed between ninth-grade students experienced in Introductory Physical Science and ninth-grade students experienced in conventional General Science in ability to manipulate basic physics laboratory equipment,…

This study applied thematic approaches to the study of introductory physics. Symmetry principles and conservation laws were chosen to serve as themes for the development of a unit on elementary particles used by students who were enrolled in a physics sequence for nonscience majors. The unit was independently evaluated by teachers of general…

Two teaching methods (learner-centered vs. conventional) were investigated as related to achievement and content covered in a basic electricity course in which 65 students were enrolled. All students participating in the study were given the Bell Laboratories Electricity Examination as a pretest and as a final test. The Otis Test of Mental Ability…

This booklet has been developed to help the layman understand and evaluate the various efforts being undertaken to utilize nuclear power for the benefit of mankind. The question and answer format is utilized. Among the topics discussed are: Our Needs for Electricity; Sources of Radiation; Radiation from Nuclear Power Plants; Biological Effects of…

This paper discusses new teaching approaches that are not heavily dependent on hardware, i.e., approaches that replace lectures with other activities such as small-group seminars and individualized instruction. Emphasis is placed on methods relevant to college physics education, such as the Keller Plan, modular instruction, audio-tutorial methods,…

These three questionnaires were developed to assess the attitudes of British secondary students toward scientific subjects as taught in their schools. Each questionnaire contains 33 Likert scale items with five choices ranging from "strongly agree" to "strongly disagree." The subjects of the inventories are: (1) physics, (2)…
