just like the topic, portrait of lecturer+ppt=make you remember more
college students are most likely to come across this kind of problems that in the end of semaster, the time of reviewing(and the students prefer to watch the powerpoint given by teachers to remember something on class which was held several months ago), a large ratio of students may forget the face of the teacher who are in charge with one of his class. this phenomenon may break the clue of memorization, and a lot useful detail would be missed by them.
so i suggest that every lecturers should put their portrait on the first page of ppt. this simple behavior may help the students to remember more and the detail delivered by lecturers if the students were concentrated on the class.
