Keeping portfolio opens a window on the way teachers try to assess students' writing improvement and learning capacity. Implementing this curricular innovation, the present study was an attempt to grow tutor-student dynamic involvement in giving/receiving written corrective feedback (WCF). To this end, two intact classes of EFL university students participated, each experiencing a distinct portfolio-keeping model (working vs. showcase) while receiving WCF from triadic sources (self, peer, & tutor) and varying tutor feedback types (indirect-unfocused vs. direct-focused). Students' performance on "TOEFL Test of Written English"andtheir grades in the previous writing course, namely "Advanced Grammar and Sentence Writing"were averaged out for both groups (Working Portfolio Group/WPG and Showcase Portfolio Group/ SPG) to assign them as low-, medium- and high-proficiency L2 writers. Written products kept in their portfolios were examined to see how differently the participants benefited from WCF sources/types. The findings revealed that WPG participants were more responsive to the working portfolio model than those in SPG who received delayed tutor evaluation in showcase portfolio approach. The article concludes with some pedagogical implications on how to use feedback to improve the quality of revised written texts and to support learning through writing.
