SwampLog is a type of journal keeping that records the facts of daily activities as experienced and perceived by practitioners. The label, "SwampLog," was inspired by Donald Schon's metaphor used to distinguish the "swamplands of practice" from the "high, hard ground of research." Keeping a SwampLog consists of recording four general types of journal entries, each distinguished by its own purpose. The general entry types are: (1) daily log entries serve as an ongoing record of daily events and receptacles for the observations, insights, and feelings that make up daily practice; (2) summary log entries are journal notations that draw together into summary format the recent past events of practice and are intended to help bring clarity and focus to those events; (3) reflections and explorations are entries intended to help develop understanding about the implications of experience; and (4) steppingstones entries propose actions through a written plan that is realistic. When used by colleagues as part of an ongoing and collaborative inquiry group, structured journalizing can encourage individual and organizational renewal. Some principles of journal keeping in collaborative environments are: (1) using the journal frequently over a long period of time; (2) writing honestly in an unpremeditated fashion; (3) rereading the journal often; and (4) keeping journals private unless one willingly reads aloud for group work.
