The present study aims to examine the types of professors" discourse strategies that are used by Spanish native professors in the classes given to Korean university students. For this purpose, we recorded 15 hours of professors" lectures in Spanish of 6 compulsory subjects on a video tape and transcribed them. After the collection of the data, we identified 17 strategies and their representative examples. On the basis of this, we recorded frequency of each discourse strategy. In this way, we were able to identify the most frequently used strategies, and tried to explain the cause of their use taking the educational situation into consideration. Because we were concerned about the use of strategies for each of the 6 subjects: grammar, conversation, culture, vocabulary, composition, and reading comprehension, we determined by analysing the frequency the particular discourse strategy that were used in each individual subject.
