Changes in the nature and content of the Secondary Mathematics Program in Australia are revealed by data from two complex studies of mathematics education in that country. This document represents an initial exploration of the information collected, with supplementary analyses by interested researchers invited. In addition to a multitude of tables…

The difficulties in comparing profile variability (a measure of test scatter) are briefly discussed and the limitations of current techniques pointed out. Test scatter is defined as individual variation in test scores between or within various psychological and educational tests. Currently, no statistical technique for the comparison of profile…

An investigation of the relationship between communication apprehension (CA) and the attainment of media competencies employs the first null hypothesis that there would be no significant difference in the achievement of media competencies and the second null hypothesis that there would be no significant correlations between the attainment of media…

The effect of prior information in Bayesian estimation is considered, mainly from the standpoint of objective testing. In the estimation of a parameter belonging to an individual, the prior information is, in most cases, the density function of the population to which the individual belongs. Bayesian estimation was compared with maximum likelihood…

Directors of the 51 agricultural experiment stations in the United States (including Guam) were mailed questionnaires inquiring as to the extent of requests which had been received for information about wind, solar, and other energy alternatives such as wood and gasahol. There was a total response of 88% with three mailings. The returned…

A study of 39 elementary schools in Chicago was conducted to compare two sets of schools, those whose students made above average yearly gains in reading comprehension and those whose students' reading gains were below average. These schools were compared on the proportion of time spent on task, on what the teacher and pupils did during reading…

An instrument was developed and field tested to provide vocational counselors with statewide vocational interest stratification patterns of secondary school youth. Analysis was made of a previously developed prototype that used slides showing workers in situ in order to elicit indications of student interest. Items from this were arranged to…

It is asserted that Steven's viewpoint on measurement--that scales are nominal, ordinal, interval, or ratio--has a limited usefulness for behavioral scientists and researchers, and that it is necessary to develop an alternative. Some limitations of Steven's theory are discussed: (1) its assumptions about the nature and purpose of measurement; (2)…

An education price index for elementary and secondary education in Canada was needed to determine what portion of expenditure growth was caused by changing prices, as opposed to the quantity and/or quality of inputs purchased. The primary objective was to construct a statistical measure that would permit expenditures on education to be deflated.…

This report is based on the results of the Survey of Doctoral Scientists and Engineers and the Nonresponse Bias Survey published by the Commission on Human Resources of the National Research Council in 1975. Possible biases in estimates of variables are examined. Estimates based on data from the 1975 survey respondents, plus the nonresponse bias…

This report from the Senate Library Committee at the University of Pittsburgh evaluates a widely publicized study of monograph and periodical use conducted at Pitt by Professor Allen Kent and his associates from 1975-1977. Areas of the study which are examined include structure in text and footnotes, and experimental design, execution, and…

THIS EXTENSIVE REPORT DESCRIBES A COUNTYWIDE SURVEY OF EDUCATIONAL NEEDS TO DETERMINE WHAT CHANGES IN SCHOOL PROGRAMS WERE MOST NECESSARY AND WHAT PRIORITY SHOULD BE ASSIGNED TO EACH OF THESE CHANGES. EDUCATIONAL NEED WAS DEFINED AS THE DEGREE OF DISCREPANCY BETWEEN WHAT VARIOUS GROUPS OF PEOPLE THINK THAT THE SCHOOLS SHOULD TEACH AND WHAT THEY…

The motion variable in the learning process was investigated in three parallel experiments (science, motor skills, social studies), each designed to meet instructional objectives of fact learning, serial ordering, and concept learning. Stimulus sequences were shown as motion pictures, sequenced still pictures, or single still pictures to 582…

With an emphasis on the problems of control of extraneous variables and threats to internal and external validity, the arrangement or design of experiments is discussed. The purpose of experimentation in an educational institution, and the principles governing true experimentation (randomization, replication, and control) are presented, as are…

Two aspects to be considered in designing a storage system for library materials are: the fraction of the collection which is to be stored; and the criteria to be used for selecting materials for storage. This study demonstrates that for a given selection criterion least-cost storage quantities can be assessed by balancing the large circulation…
