The Effects of Pre-task Planning on Fluency，Accuracy And Complexity of L2 Learners’Oral Performance.pdf

1、The present study attempts to probe into the effects of different lengths ofpre-task planning time on L2 learners' oral performance in a testing situation. Anexperiment was conducted on 95 Chinese college students who

2、were randomlyassigned to four groups and were asked to complete a battery of tasks under differentplanning conditions in which six different lengths of time were provided for planning,that is, 0 minute, 30 seconds, 1

3、minute, 2 minutes, 3 minutes and 5 minutes. 40subjects' oral data were selected for investigation. The major findings are as follows:1) the provision of planning time positively influenced the quantity of learners' ora

4、lperformance in the testing situation measured by production time, words and syllablesproduced within time limits； 2) the provision of planning time also positively affectedthe quality of learners' oral production, th
