Programming for All: Understanding the Nature of Programs
share
Computer programs are part of our daily life, we use them, we provide them with data, they support our decisions, they help us remember, they control machines, etc. Programs are made by people, but in most cases we are not their authors, so we have to decide if we can trust them. Programs enable computers and computer-controlled machines to behave in a large variety of ways. They bring the intrinsic power of computers to life. Programs have a variety of properties that all citizens must be aware of. Due to the intangible nature of programs, most of these properties are very unusual, but important to understand the digital world. In this position paper, we describe the Nature of Programs in the form of knowledge statements, accompanied by examples from everyday life to clarify their meaning. Everything is formulated in an easily understandable manner and avoids obscure technical language. We suggest that these knowledge statements must be imparted to all teachers and school students. A great way to learn and experience the nature of programs is to develop programs yourself.
