Karel J. Robot: A Gentle Introduction to the Art of Object-Oriented Programming in Java (Preliminary Edition) Joseph Bergin, Mark Stehlik, Jim Roberts, Rich Pattis Karel J. Robot: A Gentle Introduction to the Art of Object-Oriented Programming in Java takes you on a well-sequenced and thoughtful journey through the essential concepts in a first semester computer science course. Experience computer science at the level that it is most inspiring - the conceptual level. The visual environment will help you teach and your student learn because everyone will have immediate visual feedback, enabling them to see what they are doing. You will leave the Karel world with a deep understanding of polymorphism, inheritance, abstraction, modularization, and step-wise refinement, to name just a few topics. If you are an AP computer science teacher, you have just found the perfect guide to help ensure you do not lose sight of the forest (i.e. computer science) through the trees (i.e. the details of the language) Dave Wittry, Troy High School KarelJRobot is an excellent introduction to modern computer science, without letting students get overwhelmed by the details of a programming language (even though it is real Java). KJR provides a framework for understanding Object-Oriented Programming from the very beginning. Students are encouraged to develop problem-solving skills by producing projects that solve very complex problems with a relatively small set of tools. Don Slater, Carnegie-Mellon University
