Journal writing can be used as a learning tool where students write about topics of personal interest to connect new information with prior knowledge. It fosters learning by actively engaging students and allowing them to clarify and reflect on their thinking. Journals can take various forms like personal journals for free writing, dialogue journals for conversations, and subject-specific journals in math, science, and art. When used and adapted appropriately, journal writing provides benefits like monitoring student progress while emphasizing the content of entries over formal evaluations.
