The Torrance Tests of Creative Thinking (TTCT) may represent a breakthrough in the area of creativity research, since they provide a functional instrument for measuring creative potential in children, adolescents, and adults. However, there are certain technical problems with achieving interscorer reliability which may act as a deterrent to the…

The psychometric reliability of a factor, defined as its generalizability across samples drawn from the same population of tests, is considered as a necessary precondition for the scientific meaningfulness of factor analytic results. A solution to the problem of generalizability is illustrated empirically on data from a set of tests designed to…

In Dyer's Student Change Model, performance indicators (PIs) are utilized as a measure of the effectiveness of educational programs. These PIs are examined and analyzed in some detail in this paper. In particular, the reliability of the residuals, the sensitivity of the measure to sample size, the random half reliability, and the stability of the…

A factor analytic study is presented of the Learning Environment Inventory, an instrument originally designed to assess secondary students' perception of 15 school environment dimensions. Responses from 3,613 subjects were analyzed through principal components and varimax rotation procedures. In contrast to the expected structure, analyses…

Described is the development and revision over a 3-year period of the Developmental Indicators for the Assessment of Learning (DIAL), a screening test to identify pre-kindergarten children with learning disabilities. The DIAL is said to provide for gross motor, fine motor, cognitive, and communications assessment of large groups of children. Among…

Concommitant with changes in education, health care roles, and evaluation in recent years, a new six year combined B.S. and M.D. program was inititated at the University of Missouri at Kansas City. Evaluation was integrated into the academic plan in order to assess student progress toward the overall goal of becoming a safe physician, as well as…

The Message Measurement Inventory was designed to determine the dimensions which listeners consider when they judge a message. This paper outlines the development of the inventory and describes some of the first studies using it. In addition, the paper discusses tests of the validity, reliability, and precision of the scales and scaling procedures…

The optimum weighting of variables to predict a dependent-criterion variable is an important problem in nearly all of the social and natural sciences. Although the predominant method, multiple regression analysis (MR), yields optimum weights for the sample at hand, these weights are not generally optimum in the population from which the sample was…

Tested several predictions about cheating by a multivariate technique applied to two sections of a college economics course examined on the same day, with 50 percent of the questions repeated on the second exam. It was found that 36 percent of the students on the second test had used information acquired from the first test. Majors, better…

Two studies are reported that examined the extent to which job candidates were able to modify their responses on Rotter's (1966) Internal-External Locus of Control (I-E) Scale in accord with various instructional and situational constraints. Results show care should be exercised when utilizing the I-E scale in employee selection procedures.…

Item correlations performed between student ratings of instruction in various situations clearly indicate that student ratings are consistent across time, but that this consistency is related to specific educational settings and conditions as well as instructor idiosyncracies. (RC)

The use of cut-off scores with criterion referenced tests is defended in this response to two papers by Gene Glass and Nancy Burton. Suggestions for setting cut-off scores are made. (JKS)

Stimulus screening characterizes the degree to which an individual automatically and selectively responds to stimulation. Reliability and validity data are presented for a verbal questionnaire measure of child stimulus screening which employs mother reports. (Author/JKS)
