The notion of boolean is fundamental in computer science. Even if it seems simple at first sight, its introduction in the first stages of programming education reveals a number of difficulties related to the fact that it is linked to several general concepts of computer science: data types, truth values, invariants, control structures. . . Starting from this observation, the point of this article is to propose a reflection on the role of booleans in programming. We elaborate on some points concerning possible “good practices”, especially in the context of computer science teaching. In particular, we focus on boolean as a data type and on the main control structures using booleans. We also discuss the general notion of boolean expression used in programming. Finally through a few examples, we illustrate some typical uses of boolean variables.
