The waning chalk and talk days of teaching result in the loss of teaching moments. Teachers relish these moments that arise spontaneously during lectures. Professors' increasing use of PowerPoint Presentations reduces or eliminates opportunities for these precious moments. Professors reading from books or newspapers during class time are not teaching.
 Professors extensively projecting powerpoints on the screen that are also in the textbook during class time are not teaching. Students know how to read. They risk losing the interest of their students. Many students try to copy everything on the screen and seldom look up. Others are bored, daydreaming or surreptitiously using their smartphones to text friends, visit social sites, and so forth.
Professors might consider using only powerpoints not in the text. They may also consider limiting the use of powerpoints that are in the textbook to complex materials. This may result in more teaching moments.
