The purpose of this study was to investigate how student writers search various sources to generate text’s contents. For this purpose, 6th student writers’ visual recording data, interview data, texts data were col- lected and analysed. Study results showed that sources searching process has an effect on topic decision. And participants didn’t finish sources searching and selecting before writing but search sources and write repeatedly. Third, participants evaluate the quality of sources. However they could not eval- uate the quality properly and could not synthesize information properly because of a few source. Based on the results, we need to understand the importance of writ- ers’ sources searching process and to seek teaching strategies to help writers to select proper sources to write.
