“…More generally, reflection prompts can serve multiple purposes in reflection tools, including instruction (how to reflect or improve work), motivation or reminding (of certain activities), coordination (e.g., of communication during reflection), or creating synergy and knowledge integration by merging experiences (Thillmann, Künsting, Wirth, & Leutner, 2009). The characteristic aspect of prompts is that the decision of how to react to a prompt is left to the user: the prompts balance freedom and structured reflection by providing effective yet unobtrusive support (e.g., Davis, 2000;Xun & Land, 2004). Researchers have shown that asking reflection participants questions in face-to-face situations helps collaborative reflection (e.g., Daudelin, 1996), which suggests that prompts may also be helpful in collaborative reflection.…”
