The Interaction Sequence Graph records the occurrence of events according to Flanders' 10 categories of verbal interaction, the duration of each behavioral event, and the relationship of each event to those which precede and follow it. Data obtained by observing classroom teaching are analyzed and converted from a long series of numbers to a…

Text and graphs describe the Dynamic Range Configuration audiogram developed at the Central Institute for the Deaf in St. Louis, Missouri. The audiogram displays the portion of the average speech spectrum audible to the child, with and without amplification, and can be effective in counseling parents and planning appropriate amplification.…

An expense account book report encourages students to be creative and doesn't penalize students with reading and writing disabilities. Pie graphs showing expenditures a character from a book might make reveal divergent thinking skills and with a minimum of words. A reproducible worksheet is included. (MT)

Graphical perception is the visual decoding of the quantitative and qualitative information encoded on graphs. Some recent theoretical/experimental investigations of graphical perception are described, identifying certain elementary graphical-perception tasks that are performed in the visual decoding of quantitative information from graphs.…

Discusses the construction of logarithmic and arithmetic scales illustrates why they should be used, and demonstrates the difference between them. Offers suggestions for classroom applications of the scales. (FL)

The paper describes how "IBM Graphing Assistant" and "Apple Softgraph" can foster a multifaceted approach to application of mathematical concepts and how a survey can be undertaken using the computer as word processor, data bank, and source of visual displays. Mathematical skills reinforced include estimating, rounding, graphing, and solving…

Twenty-four braille readers (grades 4-12) performed a line-tracking task on tactile line graphs which differed in the type of raised line used to represent the data curves and natures of the display backgrounds. Grids impaired the trackability of every line tested, while line type and grade level had only marginal effects. (Author/CL)

Three solutions to the problem of treating compiled statistical data graphically are proposed. The first is based on the concept of index number and the other two are based on component-bar graphs. (2 references) (Author/NH)

Reports three experiments conducted to investigate factors controlling performance of nonreinforced verbal imitation. (WY)
