Public-resource computing (PRC) projects use volunteered computational resources in order to accomplish some goal [1]. Because the projects are so computationally intensive and only a small percentage of the public participates in them, improvements in efficiency are very important. One way to improve the efficiency of PRC projects is to decrease the amount of time wasted duplicating work unnec...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
