Scholar has a Journals tool that allows students to keep a journal which is, by default, shown only to the instructor and the individual student.
By default, Journals are hidden from students. To create/show a journal, click the Add Content button at the top of the Course Content space, and select Create.
Scroll down to the Participation and Engagement section, and select Journal.
Clicking this link will take students directly to the Journals tool. There, you can create the type of Journal you wish to use in your class. In this space, title the Journal and provide a short description of what you want the journal to be about and what you want your students to focus on.
This space would also allow you to change the settings for this specific journal. Click the gear icon to alter the settings. For Journals, these settings primarily consist of whether or not the Journal will be graded, but instructors can also select whether their students can edit or delete posts or comments.
Choose your desired settings and click Save. At this point the journal assignment is ready for students.
