Guidelines for selecting and using pictures to guide instructional decisions and behaviors are based on three areas of research: role of pictures and how they improve learning, how context or environment in which pictures operate can influence usefulness, and how physical and perceptual characteristics of pictures affect their function.

The Raygor Readability Estimate, described in this article, is much like the widely used Fry Readability Graph, except that it determines vocabulary difficulty by counting words of six or more letters, rather than by counting syllables. An evaluation found that Raygor was faster and easier to use and more objective than the Fry method. (RM)

A 16-item evaluation form is presented to aid in selection of appropriate computerized game materials for preschool children.

In…

Examines the variables experienced teachers of deaf children use to make decisions about the difficulty of a text for use by their students and how effective teacher judgment actually is in determining text difficulty. (EKN)

A "Signability Index" is presented for sign language interpretation of children's books. The index is based on such variables as reading rate, sentence length, quantity of text used to express thoughts, word imagery, and complexity and concreteness of passages. Suggested books for classroom reading are listed, categorized by six levels of…

This guide explains the concept of out-of-level testing and suggests a formula for estimating the occurrence of floor effects and ceiling effects, within the context of models for evaluating Elementary Secondary Education Act (ESEA) Title I programs. An analogy explains floor and ceiling effects as if test items are stored in different levels in a…

Two "sacred cows" inherent in reading instruction for disabled readers are rejected: Disabled readers must be taught with simple reading materials, and most teaching time must be spent on reading skills. Two case studies illustrate the teaching of decoding skills and "dyad reading" of books selected by the disabled reader.…

For Title I evaluations, it may be appropriate to test out-of-level; that is, to override publisher's recommendations concerning the difficulty, length, and content appropriate for a particular grade. It is seldom necessary, however, to move more than one grade down. If the mean is substantially higher than the median, then some pupils will have…
