Using Ehrenberg's application of mathematical models to the analysis and prediction of repeated buying patterns of consumers, this study focuses on the concept of library use as a form of consumer behavior. The following hypotheses were tested: designated library user groups will tend to exhibit stable behavioral patterns with respect to the…

The intent of the present study was to test for the validity and equivalency of a second-order factorial structure of the Beck Depression Inventory for and across three independent samples (n1=661; n2=239; n3=196) of nonclinical Swedish adolescents; the model under study derived from a cross-validated study of Canadian high school adolescents…

A survey of the collections of the libraries at the State University College at Buffalo (New York) was conducted to determine the physical condition of books and bound periodicals. The methodology of prior surveys at Yale (Connecticut) and Syracuse (New York) Universities was used and the following hypotheses were tested: (1) the methodology used…

This report presents the results of an experimental study which compared four different advanced retrieval methods for an online catalog to determine which are more efficient, effective, and usable. Conducted with 216 student volunteers from Virginia Polytechnic Institute and State University (Virginia Tech), the study required access to data for…

Two issues of concern in education are addressed: (1) how should educational research be carried out and (2) why do practitioners so often fail to heed the findings from educational research? The author uses the conceptualization of Stephen Pepper which distinguished four different hypotheses about the nature of the world (formism, mechanism,…

G. L. Anderson reported finding an interaction between drill and meaningful methods of instruction with fourth grade student ability and achievement. The reanalysis overturns Anderson's conclusion that there is an aptitude treatment interaction within classes. (BJG)

The Mantel-Haenszel procedure (MH) is a practical, inexpensive, and powerful way to detect test items that function differently in two groups of examinees. MH is a natural outgrowth of previously suggested chi square methods, and it is also related to methods based on item response theory. The study of items that function differently for two…

Theoretical conceptions of the value of social pretend play in the socialization process have focused on two potentially different mediating factors: play enactment and negotiation of the rules for play. In this study, observational measures of enactment were distinguished from negotiation so as to examine their independent and joint relations to…

The hypothesis was tested that humor facilitates social attraction. Students in three fourth-grade classrooms responded to two different peer rating surveys, one measuring interpersonal perceptions of humorousness and the other measuring classroom social distance. Differences between same- and cross-gender ratings were examined. Statistical…

Two studies investigated whether young children acquiring verbs at an exceptional rate can use the syntactic structure of familiar and unfamiliar verbs to make conjectures about some aspect of the meanings of those verbs. The preferential looking paradigm (Golinkoff and Hirsh-Pasek, 1981) was used to set up a naturalistic pairing of scene and…

This study analyzed the enrollment of two computer classes at a public high school in northern Indiana to see if there was any computer inequity. The two classes examined--an introduction to computers course and a computer programming course--were studied over a period of four years. The sample consisted of 388 students in four years of the…

A subset of Statistical Process Control (SPC) methodology known as Control Charting is introduced. SPC methodology is a collection of graphical and inferential statistics techniques used to study the progress of phenomena over time. The types of control charts covered are the null X (mean), R (Range), X (individual observations), MR (moving…

The relationship between analysis of variance (ANOVA) methods and their analogs (analysis of covariance and multiple analyses of variance and covariance--collectively referred to as OVA methods) and the more general analytic case is explored. A small heuristic data set is used, with a hypothetical sample of 20 subjects, randomly assigned to five…

This study reports two experiments which indicate that the processes of providing subjects with insightful representations of example programs and guiding subjects through an "ideal" problem solving strategy facilitate learning. A production system model (GRAPES) has been developed that simulates problem-solving and learning in the…

A study using a biasing paradigm examined four hypotheses regarding specific mechanisms thought to underlie the Assimilation-plus-Correction (A-C) theory of schema-text interactions. According to this theory, the ideas implied by a schema (type-1 ideas) are thought to be assimilated and obscured, while those ideas representing novel information…
