Describes and evaluates a learning model for information filtering and selective dissemination of information which is an adaptation of the generalized probabilistic model of information retrieval. The model is based on the concept of uncertainty sampling that allows for relevance feedback both on relevant and nonrelevant documents. (Author/LRW)

The third section of this two-volume report examines the utility of the model developed in section I for application in a classroom testing situation. The model was applied in arithmetic classes through a weekly testing program. The teacher specified the generic task being taught, tests were constructed using a table of random numbers to select…

A review of the literature about practices in evaluating art education programs led to the design of the new evaluation model described in this paper. The literature review revealed that a growing number of authors advocate qualitative methods, and that a debate exists regarding the combination of qualitative and quantitative data gathering and…

The state of the art in observational studies is discussed, with emphasis on explanatory research--studies of program effectiveness in which an attempt is made to explain the reasons for the results as well as describing the results. In addition to the collection of data and presentation of statistical facts, the explanatory study involves the…

The capability was studied of each of three models for producing indices that will reproduce school effectiveness rankings established a priori through simulation. The models used were a within-group regression technique, a regression model using individual scores, and a regression model using means. Data for 54 hypothetical schools on input, SES,…

Data gathered in application of Paul Kantor's demand-adjusted shelf availability model to medium-sized academic library indicate significant differences in shelf availability when data are analyzed by last circulation date, acquisition date, and imprint date, and when they are gathered during periods of low and high use. Ten references are cited.…

A model of student college choice decision was formulated and empirically tested to be used as the basis to estimate the probability of whether a student would enter a particular college. Three components of the model were students' personal characteristics, the admissions process that the students experience, and college characteristics.…

A phenomenological approach to library research utilizing qualitative research methods is contrasted to a positivist-behaviorist approach utilizing quantitative methods. Psychological understanding of a situation attained by means of accurate description, and subjectivity and associated intentionality are presented as part of the phenomenological…

This document contains the first of five volumes reporting the activities and results of a career education evaluation project conducted to accomplish the following two objectives: (1) to improve the quality of evaluations by career education projects funded by the United States Office of Career Education (OCE) through the provision of technical…

This manual describes a comprehensive system of procedures or a model constructed for the purpose of improving occupational student follow-up in California community colleges. The manual deals with such pragmatic research considerations as conceptualization of research design, sampling, questionnaire content, suggestions for data processing, and…

This monograph represents a major nationwide study on the efficacy of teaching health education and its effects on learning outcomes. The School Health Education Evaluation examined effectiveness of the School Health Curriculum Project and three additional health instruction programs in grades 4 through 7, from May 1981 to January 1985.

Organisational investments in information technologies have increased significantly in the past few decades. All around the globe and in Malaysia particularly, a number of educational institutions are experimenting with e-learning. Adopting the theory of planned behaviour (TPB) and the technology acceptance model (TAM) this article tries to…

The overall intention of this project was to enhance awareness, for those involved with persons on the autism spectrum, of cognitive behaviour therapy (CBT) strategies for treating persons with autism spectrum disorders (ASD). The project involved a literature review on autism and the use of CBT strategies for people with autism spectrum disorders…

A study of item response theory in language testing research investigated the influence of sample size on (1) the statistical test of data-model fit and (2) the invariance of parameter estimates. Data were drawn from a 1993 administration of the examination of Dutch as a second language to about a thousand candidates, using results from only the…

Implications of difficulties in using intuitive statistical reasoning are considered as they bear on the theoretic model viewing persons as intuitive scientists who make causal attributions in everyday life. Data sampling strategies and use of judgment rules to identify covariant events were investigated in two studies. Using a rule-analytic…
