(I teach college computer courses part time. I am introducing my students, who are 18-60 or so, to Windows and a GUI for the first time.)
Me: “Okay, everyone use your mouse to point at the icon and double-click on it. Once in the program, go ahead with the exercise.”
(A student raises a hand.)
Me: “Something not working?”
Student: “The mouse doesn’t seem to work. I point at the icon and double-click and nothing happens.”
Me: “That’s strange. Try it right now and let’s see what happens.”
(The student grabs the mouse, picks it up off the desk and points it at the icon like a gun and double clicks.)
Student: “See? Isn’t that little arrow supposed to follow too? Anyway, it’s broken, doesn’t work.”
Me: “Ah, well, see you actually use the mouse here on the mouse-pad like this.” *I demonstrate*
Student: “Oh my, I get it now!” *grabs the mouse and successfully launches the program*
(A few minutes go by as the students are working on the exercise, the same student raises a hand.)
Me: “Getting along with the exercise okay?”
Student: “I was, but now I need a bigger mouse pad.”
Me: “Why would that be?”
Student: “Well look at it. I have the mouse all the way to the right side of the mouse-pad, but I need to make the arrow go even further to the right on the screen. I need a bigger mouse-pad.”
Me: “Well, you can pick the mouse up–”
Student: “You told me not to do that.”
Me: “Right, but in this case–”
Student: “You’re confusing me.”
Me: “Let me see if we have a bigger mouse-pad…”
