摘要：The potential of thoughts which is possible for a person who speaks a particular language are accepted to be equal to the conceptual content of that language; “dictionary” containing the sum of the concepts. It means that “the things that a person can think are limited to the possibilities in the language he/she speaks and the thoughts of the person who speaks the language has to act within the limits of that language’s potential.”In terms of Turkish language, it is seen that Turkish sources in the form of general dictionary contain approximately 70.000 words as headwords. The headwords included in approximately 80.000-100.000 dictionaries and glossaries that are used in Anatolian dialects were not added to this number. However studies related to the vocabulary of children report that Turkish students do not benefit from the rich vocabulary of Turkish language. This paper aims to investigate Turkish student between the ages 7 and 9 during 3 years and reveal how they develop vocabulary. It is also aimed to determine the effects of variables on vocabulary development such as age, pre-knowledge, social environment, economic environment and education level. The study was conducted by the support of TÜBİTAK (The Scientific and Technical Research Council of Turkish), (TÜBITAK-SOBAG project No: 104K087).
