The next technique used by many instructors to teach critical thinking skills through writing is the journal. Expressive writing is the culmination of development for all functions of language. Though the freewrite can be termed as expressive writing it is an ending activity. Once the freewrite is over, the exercise is put aside as students move on to other parts of assignments. Journals, however, can feed on previous entries.
Students can look back and reflect on the previous ideas written the prior day, week, or month.
The student can then apply these previous ideas to new experiences, ideas, thoughts, and feelings. Allen also explained that journals serve wide, varying roles of effectiveness. First, the journal is a secure environment to respond to a wide array of topics. Second, the iournal can be used as a technique for promoting fluency in the writing process. Finally, teachers can use the journal as a diagnostic tool of students' behavior, knowledge, beliefs, etc.
