In January 1982, the College Board and Educational Testing Service implemented a technical change in the procedures used to equate scores on the Scholastic Aptitude Test (SAT). For previous editions of the SAT, a linear equating procedure was used to establish the comparability of scores on different editions. Beginning in January 1982, this…

This report examines data, on English language arts courses, generated by the Illinois Census of Secondary School Course Offerings and Enrollments conducted in l981-82. Data from the 1976-77 course census are also presented to illustrate stability or shifts in course offerings and enrollments. The first half of the document discusses the summary…

According to a formula developed to measure the adequacy of state educational finance levels, only three of six selected midwestern states provided adequate levels of expenditure per pupil in 1981-82. The formula for determining adequacy, developed by Jerry Miner and Walter McMahon, consists of totaling adequate levels of expenditure in seven…

This paper reports the development of a discrimination task to investigate the sensitivity of children aged 3-8 years to a range of timbral stimuli. The paper discusses the strengths and weaknesses of other research exploring timbral perception and explains how the findings from these studies shaped the methodological approach of this study.…

Prevailing research influenced by cognitive psychology has dealt mainly with the cognitive aspects of the human-­computer interaction (HCI). The advent of computers in schools should prompt educational researchers to scrutinize the affective and social aspects of student-­computer interactions since they play an important role in learning. A…

Studies of human problem solving have traditionally used deterministic tasks that require the execution of a systematic series of steps to reach a rational and optimal solution. Most real-world problems, however, are characterized by uncertainty, the need to consider an enormous number of variables and possible courses of action at each stage in…

In this paper, a method for analyzing data from student evaluations of teaching is presented. The first step of the process requires development of a regression model for teacher's summary rating as a function of student's expected grade. Then, two-sigma control charts for individual evaluation scores (section averages) and residuals from the…

In a pilot study of about 400 public high school students in Chicago, four innovative approaches are employed to deal with previous research problems arising from the study of juvenile delinquency: specific, proximal measures of social background, multiple indexes of delinquency, anonymous self-reports of delinquency incidence, and parametric…

This article characterizes students in a four-year technological mathematics program that integrated industrial experience with academic training. Some of the variables considered are age, sex, previous grades, quality of individual projects, graduation honors, and drop-out rate. (LS)

This study examined input enhancement and second language (L2) vocabulary learning while exploring the role of "distinctiveness," the degree to which an item in the input diverges from the form in which other items in the input are presented, with regard to the nature and direction of the effects of enhancement. In this study,…

The competencies of prospective consumer education teachers were measured, and student and demographic information variables related to achievement scores on the test were identified. Using the National Council for Accreditation of Teacher Education (NCATE) as the sampling frame, a mail survey elicited over 4,000 prospective teacher responses on…

From 1950 to 1970, daily newspaper household penetration (DNHP) levels dropped from 1.24 to 0.99 in the United States. This paper describes some of the variables involved in this decline and outlines a market-by-market statistical analysis of the relationship between the penetration levels of daily newspapers and other forms of mass media. From…

Methods are described for constructing Resolution IV screening designs that are robust to linear, quadratic, and cubic trend effects and will also keep the number of factor-level changes for some variables at a minimum. Complete designs, capable of screening up to 32 variables, are provided along with appropriate methods of analysis. (Author)

The paper reports results of a study of the distribution of productivity among sociologists who publish. Previous research had indicated that a large percentage of sociologists do not publish very often. In this study, a random sample of 300 Ph.D. members of the American Sociological Association were queried about their publishing activities. The…
