Journal writing is a learning tool that allows students to reflect on their thoughts, ideas, opinions, and reactions. It helps students clarify and develop their thinking on various topics. There are different types of journals, including personal journals for writing about feelings and interests, dialogue journals for interactive conversations, reading response journals for commenting on books, math journals for explaining problem solving processes, and science/art journals for documenting creative works and experiments. Effective journal writing is informal and allows students to freely link ideas and experiment with different writing styles.
