Discusses the history and development of Plasma Desorption Mass Spectrometry to determine molecular weights and structures of proteins and polymers. Outlines theory, instrumentation, and sample preparation commonly used. Gives several examples of resulting spectra. (ML)

Describes a technique for separating samples that range over 15 orders of magnitude in molecular weight. Discusses theory, apparatus, and sample preparation techniques. Lists several types of field-flow fractionation (FFF) and their uses: sedimentation FFF, thermal FFF, flow FFF, electrical FFF, and steric FFF. (ML)

Identifies a common laboratory problem that causes instrumentation malfunction. Provides numerous experiences of researchers whose results have been affected by humidity fluctuations, magnetic field fluctuations, trucks driving by, and other factors. (ML)

Maintains that the ability and experience of improvisation is an essential component in young musicians' education. Discusses one teacher's trial-and-error efforts in introducing improvisational exercises into her students classical training. Includes a list of resources and representative musical examples. (MJP)

Provides some tips on jazz instruction for the beginning music educator who may not have had much experience in that field. Specifically recommends teaching guide tones, the root, third, and seventh chords, as an invaluable aid to jazz improvisation. Includes musical notation showing guide tones for two jazz standards.

Adult students taking a dimensional metrology course usually do so to fulfill a need for their present employment, advancement, or expected employment. In order to assure that the quality of training is maintained it has become necessary to investigate alternatives to existing instructional approaches whereby the contents of the course can be…

This document contains three learning activity packets (LAPs) that outline the study activities for the instructional area of measuring for an Auto Mechanics I course. The three LAPs cover the following topics: rules, the outside micrometer, and the inside micrometer. Each LAP contains a cover sheet that describes its purpose, an introduction, and…

Two easily administered and scored research instruments for the study of person-environment congruency theory in the college classroom are presented. The need for such a theory-integrated approach is seen in recent research that indicates that the "common sense" approach to teacher evaluation, i.e. simply asking students, teachers, and…

THE PURPOSE OF THIS STUDY WAS TO DEVELOP A METHOD FOR DETERMINING OBJECTIVE MEASURES OF TRAINER AIRCRAFT EFFECTIVENESS TO EVALUATE PROGRAM ALTERNATIVES FOR TRAINING PILOTS FOR FLEET FIGHTER AND ATTACK-TYPE AIRCRAFT. THE TRAINING SYLLABUS WAS BASED ON AVERAGE STUDENT ABILITY. THE BASIC PROBLEM WAS TO ESTABLISH QUANTITATIVE TIME-DIFFICULTY…

THREE GROUPS OF SUBJECTS WERE TRAINED TO PRIVATE PILOT PROFICIENCY, USING A GROUND PILOT TRAINER, TO FIND HOW MANY HOURS OF GROUND TRAINING CAN BE SUBSTITUTED FOR AIRCRAFT DUAL INSTRUCTION. TRAINING TIME REQUIRED WAS COMPARED BETWEEN GROUPS AND WITH THAT OF A CONTROL GROUP NOT USING A TRAINER. THE GROUP THAT USED THE TRAINER MOST NEEDED…

This book of tests is designed to assess the competencies of the Child Development Associate (CDA) trainee: both what the trainee knows and how well the trainee works with children. The tests are designed as posttests to be administered after the trainee's completion of the relevant learning module. Each test consists of multiple choice questions,…

AN EMERGING METHODOLOGY OF PROGRAMING AVOIDS SOME OF THE UNFORTUNATE EFFECTS ON PROGRAMER BEHAVIOR PRODUCED BY INTERPRETATIONS OF TWO EARLIER METHODOLOGIES. WHILE SKINNERIAN PROGRAMING OFTEN HAS LED TO TRIVIAL PROGRAMS THROUGH PROBLEMS OF APPLICATION OF THE CRITERIA OF SPECIFIED BEHAVIORAL OBJECTIVES AND LOW ERROR RATES, CROWDERIAN PROGRAMING HAS…

This instrument was originally designed to provide a five year pre and post measure of the effectiveness of the Curriculum and Instructional Development Center at Valencia Community College. The purpose of the instrument is to ascertain faculty members' awareness and use of numerous alternative teaching styles. Four areas are covered by the…

Twelve PLATO lessons are reproduced in this document to show the status of computer guided experimentation (CGE) instructional programs. The lesson topics include a description of the CGE-PLATO instructional laboratory, an introduction to CGE-PLATO tests and special software routines, router lesson for two electrical engineering courses, and an…
