The meta-analysis investigated the effects on achievement of type of graphing paper employed in displaying student performance data collected over time based on 15 controlled studies with 16 effect sizes. No significant differences in student achievement were found between studies using six-cycle and studies using equal interval paper graphing…

This update of 1978 bibliometric study of online retrieval literature reveals that: literature has continued to grow, reaching peak annual output (504 papers) in 1981; conference literature has become centralized in four major proceedings; online retrieval papers have appeared in 479 journals; and 31 authors have contributed 10 or more papers.…

Discusses current use of psychological theory in software science and reviews recent developments in cognitive psychology relevant to programing (human information processing, expert-novice differences). Critique of Maurice Halstead's model of cognitive aspects of programing and a structured data flow perspective (control flow and data flow…

This paper summarizes the state of instructional software being produced by commercial sources in the United States as of late 1984, and reports some of the trends which led up to that state. After a brief background synopsis and description of the procedure used to obtain information, the document discusses such topics as: amount of software…

Discusses research on representational pictures, which share physical resemblance with the concept the picture represents; analogical pictures, which convey a concept; and arbitrary pictures, or highly schematized visuals related logically to the things they represent. The contributions of each type to adult conceptual learning and learning from…

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…

Examination of how far research work on the design of printed text can inform research on the design of electronic text centers on three areas: the layout of instructional text, the role of typographic cueing, and the presentation of graphic materials. Future research needs are discussed, and 101 references are provided. (LRW)

A broad range of well-structured problems--embracing forms of diagnosis, catalog selection, and skeletal planning--are solved in expert computer systems by the method of heuristic classification. These programs have a characteristic inference structure that systematically relates data to a pre-enumerated set of solutions by abstraction, heuristic…

Reviewed are 11 studies reported in Dissertation Abstracts International for Social Sciences in 1989. Topics include problem solving, mathematics education, LOGO computer language, implementation of instructional computing, algebra, effects of differential grouping on learning science skills, simulations, and graphing as they relate to the use of…
