Abstract
Three teachers who previously worked in the same place co-authored a paper after one of them moved to another workplace. They co-reviewed their collaboration to identify factors contributing to its success. This was done by reviewing their three-month collaboration individually using a teaching portfolio chart, then preparing a statement together and analyzing the text data through SCAT. The following concepts emerged: they aimed to "produce a deliverable" to the work; they endeavored to "communicate and share," "cooperate" and "self-disclose" during the process; "learning" brought a "sense of achievement" and motivated them to "develop the collaboration" further; and co-reviewing has confirmed the "value of review".
