  • Encourage students to observe and contribute to the bulletin board.
  • Exhibit bulletin board pictures during instruction time.

The illustrations which are used on the bulletin board may be recovered from the display and used during subject matter presentation. If the bulletin board is portable, place it in front of the classroom, and if the illustrations are large enough for everyone to see, it will not be necessary to remove the pictures. It is also helpful to have the illustrations arranged on the bulletin board in the proper sequence.

An important blackboard outline may be transported to the bulletin board in simple chart form at the completion of the subject under discussion. Illustrations pertaining to this specific outline may also be displayed. Subject matter presented by motion pictures, film strips, slides etc may be reviewed by displaying related material on the bulletin board immediately after the showing. Interesting titles may be prepared by cutting them from magazines and newspapers.
