The United States Training and Employment Service General Aptitude Test Battery (GATB), first published in 1947, has been included in a continuing program of research to validate the tests against success in many different occupations. The GATB consists of 12 tests which measure nine aptitudes: General Learning Ability; Verbal Aptitude; Numerical Aptitude; Spatial Aptitude; Form Perception; Clerical Perception; Motor Coordination; Finger Dexterity; and Manual Dexterity. The aptitude scores are standard scores with 100 as the average for the general working population, and a standard deviation of 20. Occupational norms are established in terms of minimum qualifying scores for each of the significant aptitude measures which, when combined, predict job performance. Cutting scores are set only for those aptitudes which aid in predicting the performance of the job duties of the experimental sample. The GATB norms described are appropriate only for jobs with content similar to that shown in the job description presented in this report. A description of the validation sample is included. (AG)

This programed text on electromechanical energy conversion (motors and generators) was developed under contract with the U.S. Office of Education as Number 12 in a series of materials for use in an electrical engineering sequence. It is intended to be used in conjunction with other materials and with other short texts in the series. (DH)

BETWEEN 2 AND 8 HOURS ARE REQUIRED FOR USE OF THIS TEXTUAL OR REFERENCE MATERIAL ON ELECTRIC MOTORS. IT WAS DEVELOPED BY AN AGRICULTURAL EDUCATION-AGRICULTURAL ENGINEERING SPECIALIST ON THE BASIS OF CONFERENCES WITH SUBJECT MATTER SPECIALISTS, TEACHER EDUCATORS, SUPERVISORS, AND TEACHERS. THE OBJECTIVES AND SUBJECT MATTER CENTER AROUND THE FOLLOWING QUESTIONS -- (1) WHAT ARE THE ADVANTAGES OF ELECTRIC MOTORS, (2) WHAT FACTORS SHOULD I CONSIDER IN SELECTING AN ELECTRIC MOTOR, (3) HOW CAN I IDENTIFY AND SELECT THE PROPER TYPE AND SIZE OF ELECTRIC MOTORS, (4) HOW SHOULD I INSTALL THE MOTOR PROPERLY, (5) WHAT CARE SHOULD I GIVE AN ELECTRIC MOTOR, (6) HOW CAN I DETERMINE WHAT IS WRONG WHEN A MOTOR WILL NOT OPERATE, AND (7) WHAT ARE THE IMPORTANT PRINCIPLES OF ELECTRIC MOTORS. DEMONSTRATIONS AND SHOP EXERCISES ARE SUGGESTED. ILLUSTRATIONS ARE INCLUDED. DESIGNED FOR BOTH HIGH SCHOOL AND POST-HIGH SCHOOL USE, THE MATERIAL IS APPROPRIATE FOR THOSE STUDENTS WHO HAVE AVERAGE ABILITY, AGRICULTURAL INTEREST, AND AN OCCUPATIONAL OBJECTIVE.
