The Question and Answer forum is best used when you have a particular question that you wish to have answered. The teacher posts a question and students respond with possible answers. By default a Q and A forum requires students to post once before viewing other students’ postings.
Example: Teacher wants to make sure the students have understood the today’s session. Teacher posts the question related to today’s session topic. Student post their responses without seeing what anyone else has answered. After they post, they can see their classmates post.
Students can not view other student’s post until they post anything.
Once student post their post, they can see other posts.
