Reports the results of an in-depth examination of middle school children's graphing skills and misconceptions. Also discusses a study in which students learned graphing skills through microcomputer-based laboratory (MBL). (ML)

Reviews for three software packages are given. Those packages are: 20/20 Statistics, Graphing Equations, and COMPUCALC. The first package is a set of programs for use in introductory statistics, the second contains four programs for studying the graphing of equations, and the third contains examples and techniques from calculus. (PK)

Argues that while microcomputer and graphing calculators have evolved to a stage where they should be used routinely by mathematics students at all levels, there is sometimes potential to mislead students with computer generated graphs. Examples are included. (PK)

Argues that before topics are added to or deleted from the traditional mathematics curriculum, it should be determined how technology can be used to teach that content. (PK)

This article investigates two common methods of determining the line of best fit and then expands on the techniques used in these methods to find the line of best fit by graphing, estimating and using a microcomputer. (PK)

An activity involving the charting of the spread of a disease is described. Arrows are used to develop models of the progression of the disease. (MNS)

Reviews recent research on the rate of implementation and impacts of office automation (i.e., expanding microcomputer use, expert systems, electronic publishing) and outlines how these impacts may lead to changes in roles and services of libraries and information professionals. (Author/MBR)

Describes a freshman chemistry experiment designed to introduce scientific methodology, provide practice in measurement skills, and illustrate a fundamental chemical relationship (conservation of volume). Provides the experimental design, a materials and equipment list, sample calculations, and results. (JM)

This investigation evaluated performance of university students on visual and nonvisual versions of an achievement test. Two experimental designs assessed the effects and interactions between visual and nonvisual instructional modes, order of drawing test (before or after verbal/visual achievement test), and mode of drawing test (verbal cued or…

Reports results of survey of materials challenged in Manitoba's school and public libraries conducted between September 1982 and August 1984 to identify who challenged what, why, and the results. Findings from similar surveys in Alberta, Wisconsin, and Minnesota are also reported. Materials challenged are listed, noting complaint, complainant, and…

Based on current literature, this article proposes a two-dimensional matrix consisting of factors extracted from domains having constraining effects on school operation and of environmental attributes that conceivably describe those external factors identified. An instrument capable of constructing graphic representation of constraint sizes is…

Describes the Department of Technology of the Houston Independent School District's program of computer literacy to prepare teachers, administrators, and parents for the integration of microcomputers into the school district's curriculum. Training tenets, questions to consider regarding program, student, teacher, hardware, and software needs, and…

Surveys were performed in 1977 and 1982 to determine trends in graduate library and information science instruction in five main course categories: library automation, information storage and retrieval, systems analysis, interactive computer systems, and programing. Results of analyses of school course catalogs are compared and current trends are…

Describes three experiments measuring changes in children's social speech which used the presence or absence of partitions allowing partial visual contact to alter verbal communication contingencies between players. Altered levels of speech and specificity confirm importance of physical environmental factors in regulation of children's play. (MBR)

Problems of scale typically arise when comparing test score trends, gaps, and gap trends across different tests. To overcome some of these difficulties, we can express the difference between the observed test performance of two groups with graphs or statistics that are metric-free (i.e., invariant under positive monotonic transformations of the…
