the presenter could move dari one field to the other

This not to suggest so that presenter “berkeliaran” all through the room (the habit yang very annoying that caused peserta must change his position continually). But, to make the transition between tujuan or the topic studied, the presenter could move dari one field to the other field from the room atau the stage and, when moving, berikan the dialogue that will move the aim/the topic during ini to that was following.
