A comparison between teaching approaches of “dialect”, in old and new educational systems in Iran’s high school books, accompanying with noun morphology study in Iran’s central dialects

There is a vast variety of Iran’s dialects. They are spread in a wide geographical domain and have had evolution during centuries. The study of these dialects is the key to many unknown linguistic subjects and also the knowledge to cultural attachments between Iranian linguistic communities. This article is divided to two parts. The purpose of first part is comparing the approaches of presenting linguistic subjects in Iran’s high schools; mainly based on educational books of old and new system. This descriptive/comparative analysis shows that elimination of linguistic subjects based on structuralist  approach in new Persian language books and also shifting the syntax  to Persian literature book, is a sign of regression to the traditional grammar. Also, adding some free lessons as “local dialects and literature”, to be written by local teachers and students, requires academic knowledge about it. For accomplishing this goal, second part introduces central Iranian dialects as an example. The sub-branches were analyzed from morphological  point of view. One of the purposes was showing the attachement of these dialects with old periods of Persian language. The descriptive study showed that in  north-eastern sub-branch of central dialects and most dialects of Tafresh sub-branch, grammatical gender and also declension of noun in oblique forms, still exists. It shows that both  sub-branches have saved the traces of Old Persian grammar.
