Current research on information processing suggests that short term memory plays a central role in the sorting and manipulation of text information during reading. Because an entire text cannot be processed simultaneously, successive "chunks" or units of information enter the short term memory where they are compared to the reader's previous…

The definition of progress as applied to writing research and practice is examined, and three different approaches to understanding the writing of exceptional children are considered: a literal approach, an interpretive approach, and an evaluative approach. The scientific and social implications of each of the approaches are considered.…

This bibliography provides citations to studies of word/letter frequencies and vocabulary applications based on issues of word frequency. While the original intent was to gather information pertinent to developing communication board vocabularies for argumentative communication systems, these resources should be useful for a variety of word…

Using seven trainable mentally-retarded students, aged 10-19, the study assessed the efficacy of an action mnemonic procedure for teaching letter-sound correspondences. The subjects were successfully trained to emit appropriate action-sounds in the presence of pictures incorporating the target letter, with picture-prompts being gradually faded to…
