Hello!
You are missing the excerpt, is this one?
So I called up my mentor, and I called up Andy Van Dam. And I said, Andy, I just gave a two-week assignment, and they came back and did stuff that if I had given them a whole semester I would have given them all As. Sensei, what do I do? [laughter] And Andy thought for a minute and he said, you go back into class tomorrow and you look them in the eye and you say, "Guys, that was pretty good, but I know you can do better." [laughter] And that was exactly the right advice. Because what he said was, you obviously don't know where the bar should be, and you're only going to do them a disservice by putting it anywhere. And boy was that good advice because they just kept going. . . .
In that sense, the answer would be:
Randy Pausch believes that his students, although they don't complete any task, they do have a good potential.
Hope have helped.
I personally I agree with the idea!
Technology provides many opportunities which without it would not be possible, for example the opportunity to watch an educational video about body parts for an anatomy class or the opportunity to practice programming for computer science class. Technology provides the opportunity for the students to learn or practice at home and without it, the students would not have sufficient sources to learn from.
