A study examined the relationship between self-perceived leadership ability and aspiration levels among 262 randomly selected consumer and home economic students in grades 7 through 12. The Dimensions of Self Concept (DOSC) questionnaire and a demographic survey instrument were administered to the students to gather data on their gender, age, and…

A model of research design anxiety reactions, that was adapted from the work of P. B. Cemen (1987) on mathematics anxiety reactions, was tested. The sample consisted of six classes of 152 master's degree students in a graduate educational research design course. Most were full-time teachers pursuing the master's degree part-time. Students were…

DIMTEST is a statistical test procedure for assessing essential unidimensionality of binary test item responses. The test statistic T used for testing the null hypothesis of essential unidimensionality is a nonparametric statistic. That is, there is no particular parametric distribution assumed for the underlying ability distribution or for the…

Studies comparing neuromotor and mental functioning of normal and disabled populations have shown that lower cognitive functioning is significantly related to lower motor functioning for retarded or disabled children but not for normal children. In an effort to further examine the relationship between these two functions, a study was conducted of…

Undergraduate students who were given specific instructions to form mental images while reading a text passage containing spatial information scored significantly higher than the control group on a drawing posttest. Significant correlations also resulted between the test scores and both reading time and use of imagery. The use of imagery…

This paper illustrates the transformation of a raw data matrix into a matrix of associations, and then into a factor matrix. Factor analysis attempts to distill the most important relationships among a set of variables, thereby permitting some theoretical simplification. In this heuristic data, a correlation matrix was derived to display…

Semantic noun classes in Emai, an Edoid language of Nigeria, are examined with respect to a process of Reference Point Marking (RPM) in order to explore the relationship between discourse and lexical semantics. Across pre- and post-verbal positions subcategorized by verbs like "rere" ("to be far"), these classes are shown to…

This paper focuses on a critical analysis and reanalysis of two earlier multisection validity meta-analyses of student ratings of instruction. The reanalysis is based on a sharpening of criteria for: (1) including studies in the meta-analysis; (2) defining key study characteristics that influence results; and (3) calculating the correlational…

This study investigated learners' preconceptions of interactive video (IV), instructional television (ITV), and television (TV), and compared three treatment groups on learners' perceptions of invested mental effort and achievement on a test of recall and inference. The three treatments consisted of an IV lesson that included practice questions…

The aim of this study was to describe and compare the socio-economic factors that can be expected to influence the education system in Portugal, where urbanization has been very slow. The report examines basic needs in Portugal's 18 districts and makes recommendations about resource allocation to planners of adult education programs. Extensive…

Two techniques for detecting differential item functioning (DIF) of test items are compared: (1) item response theory (IRT), using the three-parameter model; and (2) Mantel-Haenszel chi square techniques (MHCS). The steps necessary for identifying differentially functioning items are identified for both approaches. Using data from the 1988…

A survey of college sophomores (N=671) at Georgetown University (District of Columbia) was conducted to measure the extent of their participation in intellectual pursuits and other complementary or competing activities. Principal components analysis was used to identify questions which measured underlying tendencies, and weighted indexes were…

This was a replicative study that was initiated with a journeyman level certification instrument for an international union, when industry monitors were observed suggesting to examinees to "go with your first response." The question arose whether this was a researched-based practice. If not, wouldn't this practice inject constant error…

The Test of Standard Written English (TSWE) is a 50-item multiple choice instrument designed to assess the ability of college students to use English. In this study, based upon a sample of 45 students, the TSWE was revalidated with writing samples. The coefficient of 0.54 was most impressive given that the TSWE scores were restricted to those…

The role of pragmatic particles such as "you know,""I guess," and "man," which occur primarily in spontaneous speech are examined. Pragmatic particles and impromptu speech are defined in terms of prototypes and the social and cognitive causes for the two phenomena are discussed. A distinction is made between core and…
