The programs WordSmith and VocabProfile were used to research lexical differences between essays written in English by Spanish undergraduates and a set of essays independently judged as being of TWE grade 6 standard. The results indicated that writing by this group of students was generally characterised by low lexical variation, a preponderance…

This report contains analyses of key aspects of the scope, quality, and vitality of the Nation's science and engineering enterprise and global science and technology.

This paper reports the findings of an experiment that investigated the reactions of Saudi college students to collaborative learning techniques introduced in two modalities: face-to-face and web-based learning. Quantitative data were collected with a questionnaire that examined the changes of three constructs: attitudes toward collaboration,…

The purpose of the study is to examine the differential validity and prediction of the SAT using a nationally representative sample of first-year college students admitted with the revised version of the SAT. The findings demonstrate that there are similar patterns of differential validity and prediction by gender, race/ethnicity, and best…

The authors' goals in the study were to investigate the possible gains made by including multiple assessments of status in the prediction of change in psychosocial adjustment and to compare the effectiveness of continuous and categorical measures of peer status in predicting adjustment. The authors obtained continuous and categorical measures of…

This book discusses the motivations that cause adults to go to the public library. It is grouped into eight sections concerning: (1) the research methodology and results used to determine four motivators that were good predictors of library use; (2) the development of library research; (3) several characteristics of library users in terms of…

Factor analysis and Rasch measurement are compared, showing how they address the same data with different interpretations of numerical status. Both methods use the same estimation method, with different measurement models, and they solve the same problem, with different utility. Factor analysis is faulted for mistaking stochastic observations of…

Due to concern for test security and fairness, three new performance-based English placement test writing prompts were developed in a large midwestern university for incoming students of English as a second language, and the degree of prompt variability was investigated from multiple perspectives, including "fit-to-specification,"…

The purpose of this study was to replicate and extend previous gender difference research by identifying differences in value priorities. College graduates were given the Rokeach Value Survey as part of their testing prior to graduation in the spring of 1989, 1990, and 1991. Using the Mann-Whitney U statistic, significant differences between the…

A population data set was randomly generated from which a random sample was drawn. This sample was randomly divided into two data sets, one of which was used to generate parameter estimates, which were then used in the second data set for cross-validation purposes. The best variable subset models were compared between the two data sets on the…

College and University Personnel Association (CUPA) presents its survey results of salaries of administrators in higher education for 1989-90.

Problems associated with the use of the Higher Education General Information Survey (HEGIS) data to make institutional comparisons are discussed. It is noted that information collected by HEGIS includes data on enrollment, degrees, finances, employees, libraries, and physical facilities. Attention is directed to the following problems with the…

Data from both the 1970 and the 1980 Census are used to determine changes and trends in artist occupations and in the numbers of artists. The effects of changes in methods utilized to count artists in the 1980 Census are outlined, and estimated rates of growth by artist occupations are provided. The percentage of women artists, the ethnic…

A third annual study, involving 107 higher education institutions (39 public, 68 private) was conducted to determine rate and occupancy trends in housing operations of the Middle Atlantic Region. Each responding institution was asked to state its basic nine-month double-room rate or to compute an average rate if they have more than one. It is…

Five comparisons were made relative to the quality of estimates of ability parameters and item calibrations obtained from the one-parameter and three-parameter logistic models. The results indicate: (1) The three-parameter model fit the test data better in all cases than did the one-parameter model. For simulation data sets, multi-factor data were…
