This paper is on the design of foundations for English curriculum on the basis of discipline centered curriculum to give academic and pedagogic platforms for curriculum development. For these purposes, this study finds theoretical and pedagogic elements, and inquiries into their natures and relationships. Theoretical foundations should reflect both general education theories and the features of the subject such as English. These foundations can include linguistics, psycholinguistics and sociolinguistics, which interact in both academic and pedagogic contexts. Specifically, linguistics (the nature of language) has some features such as expressiveness, productiveness, semantics, commonness and regularity. The theories of psycholinguistics can be grouped into behaviorism, cognitivism and humanism. Sociolinguistics focuses on key elements such as the language user as a social being, variations of language, social context and social use of language. The pedagogic elements such as content system, learning elements and social context which directly come from the theoretical elements also interact each other indirectly.
