Describes the experimental arrangement for x-ray analysis of samples which involves the following: the radioisotopic x-ray disk source; a student-built fluorescence chamber; the energy dispersive x-ray detector, linear amplifier and bias supply; and a multichannel pulse height analyzer. (GS)

Describes an apparatus that provides continuous flame colorization for the study of the emission spectra of metals. (GS)

THE SCIENCE PROGRAM AT NOVA HIGH SCHOOL IS STRUCTURED TO MEET THE NEEDS OF A SCIENTIFIC SOCIETY. THE JUNIOR HIGH PROGRAM EMPHASIZES THE ACCUMLATION, TABULATION, AND ANALYSIS OF DATA. THE SENIOR HIGH PROGRAM MAKES USE OF THESE PROCESSES IN THE INVESTIGATION OF VARIOUS SUBJECT AREAS. THE UNITS COMPOSING THE HIGH SCHOOL CURRICULUM ARE DESCRIBED. UNIT…

SURVEYS WERE CONDUCTED TO DETERMINE THE AVAILABILITY OF HIGH SCHOOL SCIENCE FACILITIES AND EQUIPMENT IN SEVEN STATES. THIS WAS ACCOMPLISHED THROUGH PERSONAL INSPECTIONS BY A PROJECT COMMITTEE, USING CHECKLISTS OF APPROXIMATELY 850 SCHOOLS SELECTED AT RANDOM. AN ANALYSIS OF THE DATA WAS THEN MADE, AND SOME GENERAL IMPLICATIONS WERE SUGGESTED.…

THE PURPOSE OF THE LABORATORIES IS TO DEVELOP FOUR BASIC SKILLS IN FOREIGN LANGUAGE STUDY--AURAL UNDERSTANDING, SPEAKING, READING, WRITING, AND TO SUPPORT AN UNDERSTANDING AND APPRECIATION OF THE CULTURE OF THE COUNTRY STUDIED. THE LABORATORY PROVIDES INDIVIDUAL SEMI-SOUNDPROOF BOOTHS EQUIPPED WITH HEADPHONES, MICROPHONES AND TAPE RECORDING…

A 4-YEAR PROGRAM OF COOPERATIVE ACTIVITY IN FOREIGN LANGUAGE INSTRUCTION WAS UNDERTAKEN BY 10 MIDWEST COLLEGES. THE BASIC OBJECTIVE OF THE PROGRAM WAS TO IMPROVE TEACHING AND CURRICULAR PRACTICES FOR FOREIGN LANGUAGE MAJORS AND FOREIGN LANGUAGE TEACHING MAJORS. UNDER THE DIRECTION OF A FULL-TIME COORDINATOR, AN OFFICE FOR THE PROGRAM WAS…

The research reported is intended to provide a body of information on technical-scientific shop and laboratory education in the field of technological education. The study seeks to address the dearth of organized information on the utilization of laboratories in the technical education context. Various programs involving use of laboratories are…

A program designed to increase studnet interest and provide motivation in a third-year systems and measurements laboratory in mechanical engineering is provided. The philosophy of the course, instructional techniques, equipment design (including schematics and photographs), suggested activities, and student reactions to the course are presented.…

Findings of two recent surveys on safety equipment in laboratory facilities are presented. The first survey was a pilot study of emergency shower and eye wash equipment. This study was followed by a more comprehensive random survey of safety equipment in 2,820 labs. Among other findings, the surveys indicate that many plants are underequipped, or…

This booklet is one of the booklets in the "Understanding the Atom Series" published by the U. S. Atomic Energy Commission for high school science teachers and their students. The instruments used to detect both particles and electromagnetic radiation that emerge from the nucleus are described. The counters reviewed include ionization chambers,…

Monetary awards totaling more than $12 million for the Fiscal Year 1972 for the improvement of undergraduate assistance are presented in tabular format. The awards are divided into two categories: 1) laboratory and other special equipment, and 2) closed circuit television equipment. The awards are arranged by state. (MC)

This paper presents ideas on using programed instruction in the language laboratory for second language learning. Linear programing is more suited to language instruction than is branching, because the former more easily allows comparison between the students' and teachers' solutions and is technically less complicated and less expensive to…

Explains a technique by which three dimensional displays of transistor characteristics can be demonstrated on a cathode ray tube. (CP)
