In the introduction to this volume of a two volume document (See also TE 002 131.) written for curriculum developers, Donald Bateman identifies the recent periods in the development of linguistic thought and methodology, and presents language curriculum development as the continuing exploration of the processes of evolving linguistic structures. Thomas G. Shroyer, in "An Investigation of the Semantics of English Sentences as a Proposed Basis for Language Curriculum Materials," (1) sets forth case relations through an examination of types of sentences, (2) describes a component of a grammar designed to incorporate case relationships into a description of semantic deep structures, (3) illustrates the use of the results of the above developments in the critical reading of poetry, and (4) indicates future areas of study. Barbara Van Horn, in "An Anecdotal Account of a Classroom Investigation of the Semantics of English Sentences," indicates ways in which grammatical principles may be applied to literature, advertising, composition, and sentence structure.
