The Laboratory Structure and Task Analysis Inventory (LAI) is an instrument designed to facilitate the analysis of laboratory investigations in secondary school science. It yields a quantitative picture of the kinds of activities required of a student in performing laboratory investigations. The report includes guidelines for the use of the…

In the first of two experiments, positive and negative expectations about a teacher were induced in a student who was about to be taught by that teacher, and both verbal and nonverbal measurements were taken. Results showed that subjects responded quite directly to the experimental manipulation. In the second experiment, a student simulated some…

The experiments in this manual represent state-of-the-art techniques which should be within the budgetary constraints of a college physics or chemistry department. There are fourteen experiments divided into five modules. The modules are on X-ray fluorescence, charged particle detection, neutron activation analysis, X-ray attenuation, and…

Designed for tenth-grade students, this activity book contains sixty-three electrical experiments. Experiments focus on topics such as the direction of flow of electricity in an electric circuit, comparison of heating effect using different amounts of current, comparison of heating effects of electric current in conductors of different sizes, and…

THE MAJOR CONCEPT OF THE UNIT IS THAT SOMETHING MUST BE DONE TO PARTICLES IN ORDER TO STUDY THEM. ATOMS ARE COMPOSED OF TWO KINDS OF CHARGED PARTICLES--PROTONS AND ELECTRONS. ANY DIFFERENCE IN THEIR NUMBERS RESULTS IN A CHARGED BODY. IF ENOUGH CHARGED BODIES ARE PRODUCED, THEY WILL AFFECT CHARGE DETECTORS. CONCLUSIONS CAN BE DRAWN FROM THE…

IN THE BIOLOGICAL SCIENCES DEPARTMENT OF SACRAMENTO CITY COLLEGE, EMPHASIS HAS BEEN PLACED ON A TYPE OF INDEPENDENT STUDY INVOLVING SELECTION, DESIGN, PERFORMANCE, AND REPORTING OF AN EXPERIMENT TO EVALUATE AN HYPOTHESIS FORMULATED BY THE STUDENT CONCERNING A TOPIC OF HIS SELECTION. THE FACULTY HAS DEVELOPED A PROJECT SELECTION FORM, WITH…

THE PURPOSE OF THIS RESEARCH WAS TO EXAMINE THE EFFECTS OF SEVERAL MEASURES OF WORD-RELATEDNESS ON SEVERAL VERBAL LEARNING TASKS--PRIMARILY PAIRED-ASSOCIATES LEARNING AND VERBAL DISCRIMINATION LEARNING, WITH INCIDENTAL ATTENTION GIVEN TO FREE RECALL AND SEMANTIC GENERALIZATION. THE STRATEGY WAS TO SELECT A SAMPLE OF WORD PAIRS (240 COMMON NOUNS…

THIS STUDY WAS PHASE 1 OF A 2-PHASE PROJECT DESIGNED TO CHANGE TEACHER BEHAVIOR WITH THE OBJECTIVE OF IMPROVED CLASSROOM UTILIZATION OF NEW INSTRUCTIONAL MEDIA. PHASE 1 TRIED TO INCREASE TEACHER KNOWLEDGE OF MEDIA VIA A MONTHLY NEWSLETTER, "THE CIRCULATOR," DISTRIBUTED IN 5 DISSEMINATION PATTERNS TO 2,200 EDUCATORS IN PENNSYLVANIA. A…

A SURVEY OF THE MEMBERS OF LOCAL 617, INTERNATIONAL BROTHERHOOD OF ELECTRICAL WORKERS, SAN MATEO COUNTY, CALIFORNIA, REVEALED THAT THE ELECTRICIANS FELT THEY NEEDED--(1) A REVIEW OF THE FUNDAMENTALS OF ELECTRICITY AND ELECTRIC CIRCUIT THEORY, BOTH FOR AC AND DC CURRENTS, (2) NEW APPLICATIONS AND USE OF ELECTRICAL TEST EQUIPMENT, (3) THE ABILITY TO…

THIRTY-SIX COLLEGE FRESHMEN WERE MATCHED FOR MATH ABILITY AND RANDOMLY ASSIGNED TO AN EXPERIMENTAL AND CONTROL GROUP, TO WORK A 71-ITEM LINEAR PROGRAM IN SCRAMBLED AND ORDERED SEQUENCE, RESPECTIVELY. AN IMMEDIATE POST-TEST SHOWED THAT--ITEM SEQUENCE HAD NO SIGNIFICANT EFFECT ON LEARNING TIME, ERROR SCORE, TEST SCORE, OR TEST TIME. PRIOR MATH…
