Author relates his practical testing of the theories of bicycle stability. Investigating the steering geometry of the bicycle, using a Fortran program, led to considering the concept of self-centering p and eventually to the successful construction of an inherently unstable bicycle. (RR)

THIS READING TEXT WAS DEVELOPED IN A CURRICULUM PROJECT, DESCRIBED IN VT 004 454, ALONG WITH OTHER MATERIALS TO STIMULATE READING ABOUT MECHANICAL AND TECHNOLOGICAL TOPICS AND TO TEACH BASIC VOCATIONAL TALENTS. THE ORGANIZING THEME OF THE TEXT IS TRANSPORTATION AND POWER. MAJOR PORTIONS OF THE BOOK ARE DEVOTED TO PICTURES AND EASY-READING…

GRADES OR AGES: Grades 11 and 12. SUBJECT MATTER: Mechanical technology. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is in two volumes. The first volume gives a brief outline of the course, breaking it down into divisions, units, and subunits. The second volume gives a detailed descriptin of each subunit in a seven-column layout across two…

The self-instructional booklet is designed to teach basic concepts of graphical kinematics if a step-by-step procedure is followed through the various frames. Each frame is composed of three main parts: (1) a statement of information, (2) a problem to be solved or a statement to be answered, and (3) the correct response. The answer sheet form and…

Presents troubleshooting suggestions specifically intended for the Apple II microcomputer which have been developed from experiences working with children and pre- and inservice teachers. Guidelines for diagnosing problems focus on the mechanical functions of the microcomputer hardware. (MBR)

Twenty-four prevocational students and 24 apprentices in motor mechanical courses were tested after training involving text alone and text with diagrams. Knowledge was no greater in either situation, despite claims that illustrations enhance comprehension. (SK)

Introduces a hands-on science project in which groups of students design machines. Recommends dividing the class into groups and provides a rubric for student assessment. (YDS)

THIS BASIC READER IS A PART OF AN EXPERIMENTAL CURRICULUM DEVELOPMENT PROJECT DESCRIBED IN VT 004 454, TO DEVELOP AND EVALUATE SPECIAL NEW TRAINING MATERIALS TO TEACH BASIC VOCATIONAL TALENT SKILLS TO DISADVANTAGED STUDENTS WHICH WERE TESTED ON APPROXIMATELY 2,500 EIGHTH AND NINTH GRADERS IN EIGHT SCHOOL SYSTEMS ACROSS THE NATION. THIS READER WAS…

The glossary is one of twenty in various subject areas of vocational education designed to assist the student in vocabulary mastery for particular vocational education courses. They are part of the Vocational Reading Power Project, Title III, E.S.E.A. This glossary is for a course in auto mechanics. It is divided into two parts: one provides the…

The answers from test questions on circular motion are analyzed in terms of the misunderstandings of resultant force, kinematics, interaction, and centrifugal force. (DS)

Argues that historical experiments replicated as closely as possible to the original enable experiences that are intellectual as well as sensual in kind. Demonstrates that learning by replicating makes it possible to learn on different levels of human activity related to mind and body. Introduces a case study of the replication of the kind of…

The term "tooling" refers to a variety of devices that increase production efficiency in manufacturing. Incorporating the appropriate tooling in the production process generally improves accuracy, speed, and safety. This in turn leads to more profit for the producer and lower prices for the consumer. This article introduces students to two common…
