This study focuses on designing an English grammar syllabus for Turkish speaking English learners, which is based on the assumption that learning English grammar will be simpler and easier for Turkish speaking learners if it is introduced in a way by which they can achieve accessibility to Universal Grammar. In this study, I analyze almost all traditional grammar modules presented in a reliable ELT reference course book referring to parameters set between Turkish and English languages, try to determine how much of these modules are accessible through first language competence, and finally transfer the results into developing a foreign language learning syllabus, accordingly suggesting a hierarchy of learning for Turkish speaking English learners. The traditional grammar modules are initially categorized as to their phrasal structures and then corresponding sample Turkish and English structures are analyzed in terms of parametric variations. Finally, a competence-based English grammar syllabus designed as to parametric variations and language particular grammatical properties is suggested. This study aims to provide Turkish speaking learners of English with an easy access to learning English grammar through their Turkish grammatical competence, getting rid of unnecessary grammatical instructions and following a natural order of derivations in foreign language grammar presentation practices and syllabus design.
