The correlation between the students' intelligence and interest and their English achievement of the SMUK St. Stanislaus I Surabaya

English is the most important foreign language as it is widely spoken in the world. We need it not only to communicate with foreign people, but we also need it to read textbooks which are mostly written in English and to keep up with the development of modem technology. English, then, has become one of the compulsory subjects of the secondary schools in Indonesia. There are many factors influencing teaching and learning; among others are student intelligence and interest. Expert says that intelligence is the individual ability to use his or her mind to learn, to adapt, and to solve a problem successfully. Everybody has their own ability and they should know how to use it correctly. M. Bucori (1982: 22) states that an interest is a person's awareness of an object, a situation, or a problem, which connect to the person herself. In this study, the writer wants to know whether intelligence and interest really influence the students' English achievement. That is why, in this study she tries to find out whether there is a significant correlation between the students' intelligence and interest and their English achievement. The writer, first, takes the available data of intelligence and interest of the second year students of SMUK St. Stanislaus I Surabaya in the form1 intelligence and interest scores. And from their academic reports she takes English achievement scores. After taking the data, the writer analyses it by using Multiple Correlation to answer the hypotheses. The steps of the hypotheses testing are composed by Arcana ( 1996: 6). In order to find out the correlation, she uses the Multiple correlation with level of significance 0,05% in which tc (-0,1601) is less than ttabel (2,000). The result of the analysis shows that there is a positive significant correlation between students' intel1igence and their English achievement. On the other hand, it is proved that there is no correlation between students' interest and their English achievement
