Conducted a reliability generalization study of Kolb's Learning Style Inventory (LSI; D. Kolb, 1976). Results for 34 studies indicate that internal consistency and test-retest reliabilities for LSI scores fluctuate considerably and contribute to deleterious cumulative measurement error. (SLD)

Discusses reliability issues in light of recent studies and debates focused on psychometrics versus datametrics terminology and reliabilities generalization. Discusses the way multiple perspectives on score reliability may affect research practice, editorial policies, and reliability generalization across studies. (SLD)

Discusses problems relating to situated cognition and cognitivist approaches to learning and instruction. Contends that authenticity and generalizability are compatible; introduces the notion of the authenticity-Generalizability (A-G) continuum, where the emphasis should be scaffolding within the continuum; and proposes two kinds of information…

Used reliability generalization to synthesize findings from 30 samples of raw data, involving 2,407 participants, about the self-reporting of emotions using the Differential Emotions Scale (C. Izard and others, 1993). Higher socioeconomic status is positively associated with increased internal consistency; gender appears unrelated to reliability…

Investigated simultaneous occurrence of emergent stimulus-response relations (functional equivalence) and stimulus-stimulus relations (stimulus equivalence). Trained 4- and 5-year olds to emit specified responses to pairs of stimuli in one setting (original training) and to emit other responses to one member of each pair in another setting…

Conducted a reliability generalization study of the Geriatric Depression Scale (T. Brink and others, 1982). Results from this investigation of 338 studies shows that the average score reliability across studies was 0.8482 and identifies the most important predictors of score reliability. (SLD)

A model which approaches the problem of characterizing distributions of test validity correlation coefficients from the perspective of finite mixture theory is presented. This estimation method offers advantages over validity generalization procedures. Examples are provided to illustrate applications of the method. (SLD)

The phenomenon of 2 x 2 x 2 arrays having nonmaximal rank with positive probability, pointed out by J. Kruskal (1989), is generalized to 2 x "n" x "n" arrays. It is concluded that a pair of asymmetric square matrices can be diagonalized simultaneously with positive probability. (SLD)

Submitted the Mathematics Anxiety Rating Scale (MARS) (F. Richardson and R. Suinn, 1972) to a reliability generalization analysis to characterize the variability of measurement error in MARS scores across administrations and identify characteristics predictive of score reliability variations. Results for 67 analyses generally support the internal…

It is reasonably well known that the ratios of consecutive terms of a Fibonacci series converge to the golden ratio. This note presents a simple, complete proof of an interesting generalization of this result to a whole family of 'precious metal ratios'.

A review of studies since 1980 reporting social interaction interventions for preschool and kindergarten aged children is provided. Focus is on generalization and maintenance efforts. Reviewed studies fall into two categories, peer-mediated and child specific, and are classified by types of generalization strategies used based upon Stokes and…

Four experiments explored participants' understanding of the abstract principles governing computer simulations of complex adaptive systems. Experiments 1, 2, and 3 showed better transfer of abstract principles across simulations that were relatively dissimilar, and that this effect was due to participants who performed relatively poorly on the…

This note considers the problem of determining, for fixed k and m, all values of r, 0 [less than] r [less than] [empty set](m), such that k[superscript [empty set](m)+1] [equivalent to] k[superscript r](mod m). More generally, if k, m and c are given, necessary and sufficient conditions are given for k[superscript c] [equivalent to] k[superscript…

This case study examines the use of two assistive technologies, the Franklin Language Master 6000b and Microsoft PowerPoint 2003, as visual support systems to aid in the vocabulary acquisition skills of a student with autism spectrum disorder (ASD). The intervention used children's literature and best practices in teaching vocabulary skills in…

This paper reports results from two studies aimed at examining whether perception of social acceptance and actual social acceptance differ according to the presence of an illusion of scholastic incompetence. Results of both studies conducted in Belgium and in Quebec (respectively 179 and 543 participants) show that children's illusion of…
