This paper examines and critiques several learning style inventories (LSI) in an effort to find the optimal research instrument for a proposed empirical study of both the quality of courseware and the impact of courseware characteristics on variations of learning effectiveness due to learner characteristics. Five LSIs are examined: (1) Dunn LSI;…

The Key Assessment System, consisting of test instruments which measure psychological functioning, work related competencies, and attitudinal and motivational characteristics, is described. The system is a vocational assessment battery designed to differentiate levels of psychophysical capabilities in a nondiscriminatory manner. It provides a…

A study examined the effects on comprehension of interspersing questions in text. The subjects, 103 seventh grade students in an urban school, were identified by scores on the California Achievement Test as either good or poor readers. They were then divided into four groups receiving the following treatments: passages without experimental…

Two experiments were conducted (1) to identify the component processes of language comprehension that draw upon cognitive capacity for their execution, and (2) to determine differences in patterns of resource allocation during integrative processing for good and poor readers. In the first experiment, nine good and nine poor college-age readers…

Four research papers on the evaluation of the Utah State Department of Employment Security's (USES's) General Aptitude Test Battery (GATB) for the deaf are presented. The studies were conducted by the test research staff of the Employment Security Commission of North Carolina from 1970 to 1979. The studies contain not only the analyses on which…

The study examined computer aptitude among 56 learning disabled (LD) and 56 non LD junior high students. Students were administered the Computer Aptitude, Literacy, and Interest Profile (CALIP). Results revealed no significant difference in computer aptitude among groups or between male and female non LD students. A significant difference was…

Among the many problems faced by family researchers in conducting experimental research in field settings is that posed by nonequivalent and intact treatment and control groups. Nonequivalence refers to the assignment of individuals to treatments on a nonrandom basis, thus generating treatment groups with different expected values on one or more…

Twenty-eight engineering students were presented with complex spatial problems to investigate the effects of spatial aptitude and strategy selection on problem solving. Aptitude was determined by spatial aptitude test scores and strategy was determined by verbal reports and latency measures. It was found that aptitude determined the efficiency…

The effectiveness of two media types (sound film and still slides with audiotape) in changing student attitudes, and their impact on students varying in field dependency levels was examined. Subjects, 82 college students scoring at the high and low extremes of the Group Embedded Figures Test (GEFT), were randomly assigned to either a (1) multi-cue…

Cognitive profile analysis of 14 rural case studies follows precisely the distribution curve found in comparison groups, in terms of the number of adults falling into each of three profile types. Regardless of age, approximately 10% are found in Type 1 and 3 categories and 80% within the Type 2 profile category (Type 1 is significantly associated…

Conventional Armed Services Vocational Aptitude Battery-7 (ASVAB) Arithmetic Reasoning and Word Knowledge tests, were compared with computer-administered adaptive tests as predictors of performance in an Air Force Jet Engine Mechanic training course (n=495). Results supported earlier research in showing somewhat longer examinee response times for…

The study is a simple statistical analysis of the ACT scores of the 1974-75 Louisiana State University-Baton Rouge graduates. Graduate students awarded advanced degrees are not included. For each college and field of study and for each of five ACT tests, these data are given: number of students, mean, middle two-thirds; range, standard deviation,…

Exploratory research with large numbers of variables and even larger numbers of relationships is likely to result in frequent Type II errors; that is falsely accepting an incorrect null hypotheses. There are three ways of reducing Type II errors: (1) choosing a lower significance level, which then increases the probability of Type I error; (2)…

Argues that standardized IQ, aptitude, and achievement tests are biased against persons of low socioeconomic status. (IRT)
