This book was written almost 50 years ago and it is still widely used within education around the world. Bloom set out to create a common framework for categorising academic ability and his resulting taxonomy is still the de facto standard for classifying cognitive skills. Don't be put off by the age of the book - it's very readable - which perhaps reflects the timeless nature of his subject matter.

Wh-movement—the phenomenon by which interrogative words appear at the beginning of interrogative sentences—is one of the central displacement operations of human language. Noam Chomsky's 1977 paper "On Wh-Movement," a landmark in the study of wh-movement (and movement in general), showed that this computational operation is the basis of a variety of syntactic constructions that had previously been described in terms of construction-specific rules.

This is a systematic presentation of the parametric approach to child language. Linguistic theory seeks to specify the range of grammars permitted by the human language faculty and thereby to specify the child's "hypothesis space" during language acquisition. Theories of language variation have central implications for the study of child language, and vice versa.
