A recent trend in introductory programming education in high schools is programming without coding such as block programming. However, practical programming requires coding skills. We consider that live programming can be the key technique to learn to the fun of coding for novice students.

Based on this idea, we have been developing a code-intensive programming environment, called Puppy. Puppy is a Kid’s version of Python that runs on an integrated environment of program execution on a physics engine. Even a small amount of coding can express a rich program. In addition, the programming environment helps to understand coding and programming execution using live programming technique. This essay reports the initial development status of Puppy with several demonstrations.
