Attitudes and motivation are two of the key factors in second language learning since positive attitudes and high levels of motivation are considered as the predictors of a successful learning process. This study aims to reveal the relation between university preparatory students' attitudes towards learning English and their language learning motivation at DEU School of Foreign Languages and to identify the factors which result in the differences in both their attitudes and motivations. This is a descriptive study with a quantitative approach. The data have been collected via the Attitudes Towards Leaning English Questionnaire and Language Learning Motivation Scale from 511 prep class students at Dokuz Eylul University, School of Foreign Languages. The data have been analyzed with means, frequency, multiple comparisons, Pearson correlation coefficient, t-test and One-way ANOVA. The results show that there is a significant positive relation between the learners' attitudes towards learning English and their language learning motivation at Dokuz Eylul University, School of Foreign Languages. Additionally, it has been found that both their attitudes and their language learning motivation vary significantly in terms of some factors.
