Growth is estimated most accurately by procedures involving the pretest-posttest difference, and for practical purposes all estimates involving this difference have approximately equal accuracy. In particular, the simple difference between pretest and posttest scores seems about as accurate as any other estimate, easier to compute, and meaningful…

The definitions provided for high order language (HOL) requirements for programming flight training simulators are based on the analysis of programs written for a variety of simulators. Examples drawn from these programs are used to justify the need for certain HOL capabilities. A description of the general structure and organization of the…

An experiment was conducted in which a computer-simulated "workshop" was used in teaching Information Reading Inventory (IRI) techniques to college students. The computer simulated an instructor who guided students through constructing an IRI and a pupil to be tested with IRI. (JY)

The intent of the study was to determine the extent to which test statistics computed by the unweighted means analysis are F-distributed. Applicability criteria were sought in terms of the number of factor levels and the degree to which cell frequencies differ. The unweighted means analysis, a frequently used approximate analysis, was contrasted…

This paper will discuss the results of a series of computer simulations comparing the Rasch logistic model to a series of models departing to various degrees from its assumption of equal discrimination power for all items. The results have implications for test construction and test scoring, indicating how closely the conventional raw score…

Item characteristic curve (ICC) theory describes the relationship between the ability of individuals and the probability of their answering a test question correctly; it is useful in estimating test scores, equating the scores of various tests, and scoring responses during adaptive testing. A simulation study of the effectiveness of the following…

The effectiveness of a computer-assisted training method using computer simulation of two subsets of the Wechsler Intelligence Test for Children--Revised was compared with traditional methods for teaching the administration of the test. Results suggest that the computer simulation was a very effective teaching method. Eleven references are listed.…

This report is the first in a series of energy use studies intended to provide real life examples of the implication of energy conservation practices. Research reports from five public school districts describing their methods of measuring and conserving energy are summarized. While investigating the responses of various school districts to the…
