IN PERSON LECTURES are essential, I believe. A live person who is expert on the topic can add emphasis on the essential ideas. "I have tried to do it the other way and here's what happened!"

These details do not show up in a text book or on a screen sent out ahead of the lecture.

The SCREEN SENT OUT AHEAD OF THE LECTURE is important also. Let the student study a chart or graph and see how things are inter related " If we increase this, there will soon be a shortage of that" etc. Then the student has in his head some new words so he can understand the lecture.

TEXT BOOK is unbeatable for random access to the topics discussed in the course. It is different from the lectures and from the screens. The screens present the topic to be covered in the next lecture. The BOOK presents the subject in an orderly way useful for overview and review.

SCREENS SENT OUT AFTER THE LECTURE or screens containing extra information such as the derivation of equation #6-14 are useful to round out the course material. Some students just have to understand the derivation before they feel comfortable using an engineering formula. These may be sent out in a folder different from the screens sent ahead of the lecture.

RECITATION SESSIONS: a classroom with 10 or 12 students led by a person who understands the subject quite well and attended the lecture (Possibly as the projectionist) and looked at all the relevant screens and the chapter in the book. Here's where the student can ask questions. The answer may be to look at a screen of extra information (the classroom has a projector on the ceiling and a screen next to the blackboard) or take a look at page # in the book.
(looking at the book may need an opaque projector ready to go whenever the leader turns it on) (Place the projector near the teacher and aim it at a mirror which sends it to the screen like they do in an optician's office.)

THE RECITATION LEADER needs to prepare by reading and listening to all the information given to the student so she can answer by saying "Remember what professor Bob said", or " look at the third screen sent out after the lecture"
