Learnerss must be equipped with problem-solving tools to deal with emerging situations. Schools and universities must become knowledge-building communities. Rapid collaborative knowledge building (RCKB) is effective strategy for overcoming crisis and solving emerging problems. The focus of knowledge-building communities is on developing collective knowledge and improving learners' problem-solving skills. Method The purpose of this study was to develop a rapid collaborative knowledge building model to encounter emerging situations according to Scardamalia, Bereiter, and Stahl perspectives. Forty mechanical engineering students (8 groups) voluntarily participated in a time overcoming race designed by Yazd university's mechanical engineering professors. Students encountered an emergent problem on the day of the competition (which involved building a boat to carry at least one kilogram in the shortest possible time, and over the course of the long haul). Specific equipment and limited time were provided equally to all teams to examine the process of rapid collaborative knowledge building. After the competition (5 hours), the results were announced, the 3  Assistant Professor, Department of Education, Yazd University, Yazd, Iran.  M.A. in Educational Psychology, Department of Education, Yazd University, Yazd, Iran.
