This study investigated the effects of types of post-reading instructional scaffolds on university-level English as a foreign language (EFL) learners’ WebQuest writing performance. One hundred twenty students, randomly selected from 8 EFL classes at a Korean university, were randomly assigned to one of three treatment conditions: (a) online Instructional Conversation (IC), (b) online recitation, or (c) no post-reading instructional scaffold (i.e., control). After reading WebQuest texts, the online IC and online recitation groups received their treatments, using an Internet-based synchronous textual communication tool as a medium for communication. The control group, on the other hand, did not receive any post-reading instructional scaffold and continued to read the WebQuest texts for the same amount of time that the IC and recitation groups received their treatments. Results showed that the online IC group outperformed one or both of the other two groups in overall WebQuest writing performance and in the specific areas of overall writing quality and content. Implications are discussed in both theoretical and practical terms.
