The purpose of this study is to investigate university students’ perceptions on their English conversation classes taught by native English speakers. Its focus is on finding out how well the students understand and how actively they participate in class, what causes difficulty in their understanding or participation in class, and whether their class helps them in terms of affective aspects and English skills. A survey was conducted on a total of 465 university students in Korea, and the collected data were analyzed to compute basic descriptive and inferential statistics. Some of the important findings are 1) over 50% of the students understand their classes well; 2) a little over 30% actively participate in class; 3) about 30~50% of the students perceive their class help them affectively; and 4) about 50% of the students perceive their class help them improve their English skills in general. These results are discussed along with other findings related to the causes of the difficulties that the students experienced. Suggestions are provided on the basis of the results and their implications.
