This document answers the question, "What has been learned about evaluation methodology from the decade of compensatory education"? Ten issues dealing with the evaluation of Title I were identified within a general theoretical framework of evaluation. For each issue it was the aim of this document to do the following: 1)to clarify the…

This document contains two papers related to the 1993-94 Schools and Staffing Survey (SASS). The first paper documents some of the problems that were encountered during student sample selection and the methods used to resolve those problems. It also provides some suggestions to alleviate some of the problems in future SASS studies. Significant…

Discusses challenges to conducting research on effectiveness of community service systems that are family-based and school-centered: underidentification of children with emotional or behavioral disorders, lack of concordance between diagnostic criteria used in school versus mental health systems, problems of comorbidity, analysis of data from…

A review of 208 studies of children with learning disabilities (LD) published in 10 major journals between 1988 and 1990 examined the extent to which recommendations concerning research design and reporting made in 1980 and 1984 have been implemented. The review found continuing problems, including imprecise subject descriptions, heterogeneous…

Possible bias due to sampling problems or low response rates has been a troubling "nuisance" variable in empirical research since seminal and classical studies were done on these problems at the beginning of this century. Recent research suggests that: (1) earlier views of the alleged bias problem were misleading; (2) under a variety of fairly…

Two basic methods exist for drawing probability samples to be used in telephone surveys: directory sampling (from alphabetical or street directories) and random digit dialing (RDD). RDD includes unlisted numbers, whereas directory sampling includes only listed numbers. The goal of this paper is to estimate the effect of failure to include…

The purpose of this study was to determine the types of research methods used to study cognitive processing development in gifted learners, from 1975-1986. Of 870 research publications identified on giftedness, 522 publications (60 percent) dealt with cognitive processing development. Research designs used most frequently were causal-comparative,…

A study was conducted at Los Angeles Pierce College (LAPC) to test the relative reliability of small-sample telephone interviewing and large-sample mailings with postcard and telephone reminders for student follow-up. The study involved conducting a telephone survey of 245 former students who had enrolled at LAPC in four program areas, and a mail…

The effects of using different data analysis methods on estimates of treatment effects of educational programs were investigated. Various regression models, such as those recommended for Title I program evaluations, were studied. The first effect studied was the amount of bias that might be expected to occur in the various settings. Results…

An investigation was conducted of the characteristics of two estimation procedures and corresponding test statistics used in the analysis of completely randomized factorial experiments when observations are lost at random. For one estimator, contrast coefficients for cell means did not involve the cell frequencies. For the other, contrast…

The fourth of a series of reports on the study, Mental Retardation in a Canadian Province, the document covers the initial months of field data gathering in Prince Edward Island, April to September 1969. The major objectives of the study, to describe and explore the most suitable definition of retardation for a Canadian population and to report on…

A survey of speech communication departments and a review of the literature indicate that most speech communication researchers continue to use college students as their primary source of subjects. The problem of sampling is discussed and methods for dealing with generality are offered. (PD)

Vocational and technical education researchers need to be aware of the uses and limits of various statistical models. The author reviews the Rasch Model and applies it to results from a nutrition test given to student nurses. (Author)

Until recently, norms of experimental reasoning have lacked systematic theoretical development. Thus, it has been easy for psychologists like Tversky and Kahneman to misclassify certain human reasoning processes as being Pascalian and invalid, rather than as being Baconian and valid. (CP)

Argues that women are unaccounted for in most phenomenographic studies, for several reasons: most research has been conducted in fields and using samples in which women are underrepresented; the traditional disciplines of study are patriarchal; and the "outcome space" is defined in cognitive terms, neglecting the affective dimension…
