Presents a tagmemic matrix of cases in German and describes the advantages of using it for ease of student recall. The tagmeme is described as a function-form unit or a slot-class correlative. (TL)

The construct validity of four measures of reflection-impulsivity was examined using a multitrait-multimethod procedure on sample of six to twelve year old educable mentally retarded children. The results indicate a minimal level of construct validity. (Author/JKS)

Discusses the use of microcomputers for automating school libraries, both for entire systems and for specific library tasks. Highlights include available library management software, newsletters that evaluate software, constructing an evaluation matrix, steps to consider in library automation, and a brief discussion of computerized card catalogs.…

Discusses the difficulty of managing rapidly changing and expanding information technologies. A conceptual matrix for managing technology-related variables is presented, and examples of using the matrix for decision making are given. The resulting improvements in communications, systems integration, and strategic planning are discussed, as well as…

Results of data analysis on 470 journal titles illustrate complexity of the fuzzy set theory modeling process, which consists of three factors--number of missing issues, citations, circulations--and its limitations in making journal binding decisions. Procedures of research, data collection, and data analysis are discussed. Matrices are included.…

Two journal-to-journal matrices for psychology in 1950 and 1960 are analyzed in terms of structural equivalence to test following hypotheses: that journals of a discipline function as a status-role relational system; that interdisciplinary journals are distant from journals of a field; that journal networks have a core-periphery structure. (26…

Introduces Q-analysis, a methodology for investigating a wide range of structural phenomena that defines structures in terms of relations between members of sets and reveals their salient features by using techniques of algebraic topology. Applications relevant to librarianship and information science are reviewed and present limitations…

Nonlinear common factor models with polynomial regression functions, including interaction terms, are fitted by simultaneously estimating the factor loadings and common factor scores, using maximum likelihood and least squares methods. A Monte Carlo study gives support to a conjecture about the form of the distribution of the likelihood ratio…

Enrollment data for 1977-1982 are used to produce an innovative map of top 42 elective courses in Drexel University's School of Library and Information Science. Data gathering and computing procedures are given in sufficient detail for replication and evidence is relevant to accreditation standards of American Library Association. (Sixteen…

A methodology for forecasting enrollments at the individual unit level is presented. It can be used to produce detailed enrollment projections (e.g., by class level by semester by year) or more aggregate information (e.g., academic or fiscal year total enrollment), and it does not require the typical institution to obtain new data. (LBH)

The planning office of a large urban university produced an induced course load matrix (ICLM) analysis to support the university's plans for undergraduate enrollment growth at its three campuses. The ICLM tables, based on the complete course histories of the 1993 entering cohort, summarize the program and course selections of a cohort of students…

Constructing a matrix model not only offers the teacher a theoretical and practical method for organizing his own knowledge about a topic, but provides a vehicle for the student to cope with contemporary knowledge explosion in a realistic and sophisticated manner. (Author)

Provides a summary of a series of research and development projects which investigated the reasons for failure in educational technology-based systems of instruction. Develops a new approach to the design of such systems and their subsequent implementation and control. A 17-item bibliography is included. (Author/CHC)

The restrictions on item difficulties that must be met when binomial models are applied to domain-referenced testing are examined. Both a deterministic and a stochastic conception of item responses are discussed with respect to difficulty and Guttman-type items. (Author/BH)

This article reviews routine-based teaching and monitoring and offers guidelines for using these strategies to track the progress of individual children with disabilities. The Individual Activity-Objective Matrix and the Group-Objective Matrix are explained as ways to help teachers to structure opportunities for a child to learn and practice…
