This study compared Korean adult learners’ English speech in dialogic and monologic tasks, measuring 57 college students’ oral proficiency in terms of holistic and analytic grades. The statistical analyses were focused on two questions: 1) how much do the holistic grades of oral proficiency and analytic grades of the four linguistic features function differently across the tasks? and 2) which linguistic feature has the strongest correlation with the holistic grades of English oral proficiency? The study found significant differences between the two tasks in five aspects (English oral proficiency, topic development, fluency, range, and accuracy). It also showed that a monologic task resulted in lower achievements in those five aspects. In the comparison of the correlations with English proficiency, the range reached the top in both tasks, followed by topic development. The study provides some helpful information regarding which types of speech tasks and linguistic features of EFL oral proficiency are more desirable for targeting in teaching and assessment.

The present study investigated students’ preferences for the types of tasks used to assess English speaking performance. It further examined whether students’ task type preferences affected their perceptions of test effectiveness. One hundred eighty-two high school students responded to a self-report questionnaire. A series of frequency analysis and paired samples t-tests were used for the analysis. The results showed that students’ most preferred task types and their least preferred ones overlapped with each other, suggesting that the task types of English-speaking performance tests used in schools are limited. The four key reasons determining students’ task type preferences were identified, including task difficulty, emotional comfort, practical value, and interest. In addition, the results indicated that students’ task type preferences could affect their perceptions of task effectiveness. Overall, the results suggest the need for developing more varied task types for English-speaking performance tests as well as helping students become familiar with English speaking performance tasks. Pedagogical implications were discussed along with study limitations.
