ABSTRACT
Computational thinking, as coined by Jeannette Wing, is a fundamental skill for all to be able to live in today's world, a mode of thought that goes well beyond computing and provides a framework for reasoning about problems and methods of their solution. It has a long tradition as algorithmic thinking which within computer science is a competence to formulate a solution of a problem in the form of an algorithm and then to implement the algorithm as a computer program. Computational thinking is not an adequate characterization of computer science as claimed by Peter Denning and he is right -- it is a collection of key mental tools and practices originated in computing but addressed to all areas far beyond computer science. As an extension of algorithmic thinking, it includes thinking with many levels of abstraction as a problem solving approach inherently connected to computer science and addressed to all students to use computers and computing skills in solving problems in various school subjects coming from various scientific and applied areas. Computational thinking involves concepts, skills and competences that lie at the heart of computing, such as abstraction, decomposition, generalization, approximation, heuristics, algorithm design, efficiency and complexity issues and therefore it is clear that basic computer science knowledge helps to systematically, correctly, and efficiently process information, perform tasks, and solve problems. Although coming from computer science, computational thinking is not only the study of computer science, though computers play an essential role in the design of problems' solutions. It is a very important and useful mode of thinking in almost all disciplines and school subjects as an insight into what can and cannot be computed.
In this talk we shall discuss a new computing curriculum addressed to ALL students in K-12 in Poland which motivates them to use computational thinking in solving problems in various school subjects. Moreover its goal is to encourage and prepare students from early school years to consider computing and related fields as disciplines of their future study and professional career. To this end, the curriculum allows teachers and schools to personalize learning and teaching according to students' interests, abilities, and needs.
The new computing curriculum benefits a lot from our experience in teaching informatics in our schools for almost 30 years -- the first curriculum was approved by the ministry of education in 1985, 20 years after the first regular classes on informatics were held in two high schools in Wrocław and in Warsaw. Today, informatics is an obligatory subject in middle school (grades 7-9) and high school (grades 10-12) and it will replace computer lessons (mainly on ICT) in elementary schools (grades 1-6). The new curriculum is also addressed to vocational education.

Computational thinking in high school courses
SIGCSE '10: Proceedings of the 41st ACM technical symposium on Computer science educationThe number of undergraduates entering computer science has declined in recent years. This is paralleled by a drop in the number of high school students taking the CS AP exam and the number of high schools offering computer science courses. The declines ...
