Journals

Students write in journals on a regular basis. This allows them to practice all writing skills and share their ideas, feelings, and personality. Journals can be adapted to reflect on learning, communicate with teachers or parents, or write to a specific prompt. Journal assessments show us grammar, spelling, style, and clarity skills. Teachers can also gauge a student’s current feelings and this helps grow relationships.

Journal time is a good time to support students who need extra help because little support is needed for explanation.

Some students are so excited to write that they do not put their best effort into how they write in journals.
Some students worry about finding the “perfect” topic and this can delay or prevent writing.
