Difficulties encountered when drawing the graphs of linear equations are discussed. Programs are developed to overcome these and worksheets are given for further practice. (MP)

Education in Great Britain has been receiving a diminishing share of the financial cake since the inception of the Rate Support Grant system and, particularly, since the introduction of post-Bains Local Authority structures. (Author/IRT)

A comparative study of the cost effectiveness of retrospective manual and on-line bibliographic searching is described. Individual task times for question analysis, searching, photocopying, shelving and output distribution were measured, and component costs for labor, information, reproduction, physical space and telecommunications calculated. The…

The iconographic means of illustrating mathematical facts is discussed along with several examples of graphical solutions to descriptive mathematics problems proposed by pupils. (MN)

Describes a number of methods of teaching graphing and in fulfilling objectives in graphing such as collecting data from the student's immediate environment and using standard graphical practice in representing relationships. (Author/RK)

The role of the coauthor relationship in the structure of informal communications networks within disciplines is explored, and the validity of coauthor graphs used to map these relationships is tested for both small and large databases. (CLB)

Proposes a new definition of the nuclear zone of a Bradford or Leimkuhler curve. The mathematical rationale is outlined, and examples of the application of this technique to citation analysis are given. (15 references) (CLB)

When the parameters of item response data are estimated by a latent trait model, some variation will remain unaccounted. If baseline graphical configurations of the residual variation can be constructed, measurement irregularities may be exposed. An analytic strategy for the graphical representation and analysis of Rasch model residuals is…

Use of Logo to teach statistical ideas is proposed for students in grades 5-10. Procedures and diagrams are suggested, with program listings for four models for graphs. (MNS)

Given is an example of the solution of maximum-minimum problems by replacing differentiation techniques with microcomputers and simple BASIC programs. (MNS)

Much can be learned from a study of rational functions and the behavior of their graphs, so their inclusion in secondary school mathematics textbooks is urged. Analysis of reciprocal relationships and when they don't apply, asymptotes, and the graphing technique are each included in the discussion. (MNS)

Alternative educational applications of microcomputer technology in allied health are discussed, including word-processing software for creation and revision of syllabi, exams, and handouts; database management software for creation of large sets of bibliographic references, storage and retrieval of data on students; spreadsheet software; and…

Three activities with Knuth functions are discussed and illustrated, with sample computer programs listed. (MNS)

Discusses the use of property diagrams as an instructional tool to help students understand and visualize important, complex thermodynamic relationships. Also discusses the approach used in preparing these diagrams, which were computer-generated as part of graduate students' research. (JN)

Empirical significance of document partitions is investigated as a function of index term-weight and similarity thresholds. Results show the same empirically preferred partitions can be detected by two independent strategies: an analysis of cluster-based retrieval analysis and an analysis of regularities in the underlying structure of the document…
