This paper reports an experiment designed to test theoretical relations among fast problem solving, more complex and slower problem solving, and research concerning fundamental memory processes. Using a cathode ray tube, subjects were presented with propositions of the form "Y is in list X" which they memorized. In later testing they were asked to…

This booklet contains a collection of brief articles with accompanying statistical tables and graphs that were originally published in 1974 issues of "American Education." A variety of statistical data are presented in a series of two-page sections; taken together, these sections illuminate many of the current trends in American…

A computer program for the simulation of complex continuous process in real-time in an interactive mode is described. The program is user oriented, flexible, and provides both numerical and graphic output. The program has been used in classroom teaching and computer aided design. Typical input and output are illustrated for a sample problem to…

It was wished to determine the relative reliabilities of graphic and semantic differential factors to evaluate applicability of two rival models to the measurement of pupil attitudes. Data was collected from a sample of sixth grade pupils on both abstract graphic and typical semantic differential scales. Reliability estimates were constructed from…

The major purpose of this experiment was to examine the effects of format (bar graphs vs. tables) and organization (by year vs. by brand) on the speed and accuracy of extrapolation and interpolation with multiple, nonlinear trend displays. Fifty-six undergraduates enrolled in the College of Education at the University of Delaware served as the…

This volume, a reprinting of a classic first published in 1952, presents detailed discussions of 26 curves or families of curves, and 17 analytic systems of curves. For each curve the author provides a historical note, a sketch or sketches, a description of the curve, a discussion of pertinent facts, and a bibliography. Depending upon the curve,…

This study investigates relationships between differences in students' achievement and differences obtained by a technique held to yield a reasonably valid representation of students' memory structures of a particular subject matter. Also investigated was the nature of the flow of information between curriculum materials, teachers, and students.…

In this autoinstructional packet, the student is given an experimental situation which introduces him to the process of graphing. The lesson is presented for secondary school students in chemistry. Algebra I and a Del Mod System program (indicated as SE 018 020) are suggested prerequisites for the use of this program. Behavioral objectives are…

This autoinstructional program deals with experiences that will aid chemistry students at the secondary school level to determine the slope of the straight line graph relating the variables in a given set of data involving a direct relationship. Prerequisites set for this activity include three Del Mod System packets (SE 018 018, SE 018 020, and…

The purpose of this research is to evaluate the effectiveness of the area (homogeneous) scales of the Navy Vocational Interest Inventory (NVII) as predictors of Class "A" school achievement and as measures of rating differentiation by comparing specific occupational scales with more general interest measures--the NVII area scales. The…

This report presents projections of school enrollment by age, sex, and grade level to the year 2000, taking into account the latest population projections prepared by the U.S. Bureau of the Census. The figures apply to fall enrollments of the civilian noninstitutional population 5 to 34 years old in elementary school, high school, and college. The…

Examines two traditional approaches to the measurement of library service--the gathering of circulation and reference statistics--and relates them in a statistical model in an attempt to define real standards against which a library's activity can be compared. Graphs comparing reference and circulation statistics are included. (Author/JD)

This survey of the use of computer assisted instruction in schools for the deaf identified 34 systems with a total of 408 terminals, predominantly in elementary and secondary schools for the deaf; 28 of these computer systems are strictly used for CAI. (Author/JEG)

An analysis of computer-based search services (ISSs) from a system's viewpoint, using a continuous simulation model to reveal growth and stagnation of a typical system is presented, as well as an analysis of decision making for an ISS. (Author/MBR)

Some problems and classroom problem-solving settings presented in a mathematics methods course for elementary teachers are described and some results of student's involvement in the program are illustrated. (MN)
