Since 1981, Karel the Robot has been instructing students in the delicate practice of programming. With all sorts of new ways to teach programming, is the Karel method still valid? As long as introductory programming is about learning to think, there's room for Karel and his universe. You learn in the beginning about Karel's world and how to move him around ever so carefully in his streets and avenues. From these simple steps, you learn how to improve Karel's programming vocabulary so that you can do more with less code. You then advance to conditional statements and more complicated repeating instructions, ending up with skills such as ordering your robot to search his space for objects. Karel proves that a lot of programming expertise can be taught with a few well-chosen exercises and an emphasis on logical thinking and clean programming. Let's hope Karel the Robot never ends up on the junk heap.

"I think Karel the Robot
is the greatest way to introduce programming concepts that I have seen."

"I first used this language in 1981 as a student. I found it to be stimulating and challenging. In 1984 I began using Karel as a teacher. Since 1984 I have used Karel every term except one. That term represented an experiment to see how students would do without using Karel. I was not satisfied; the students performed poorly relative to those who used Karel."

"There are no bits, no bytes or bugaboos to intimidate new minds to computers. Pattis et al. have done a wonderful job in assembling a simple little robot, giving it a little language to understand, giving it a little world to wander about in, and finally giving it to [us] so that we can all play and learn in Karel's world."
