Seriously, the ability to "step through" a program is HUGELY helpful for learning what programming does. I remember learning the beginnings of programming in Visual Basic for Applications inside Excel 2003. The best feature was the ability to "walk through" the program, with a yellow line highlighting the current code being executed and a window that showed all the variables and their outputs in a highly readable format. Those two things really helped me as a kid learn what programming looked like.
