A development of algorithms and writing of programs are considered as closely related but not identical parts of computer programming. Some differences between them are important for learning of computer programming, in particular, in distance learning. These differences are identified and discussed from the pedagogical point of view. The arguments for the selection of pedagogical based and cost-effective delivery modes in the case of distance learning are investigated. Practical examples supporting theoretical arguments are given on the activities of Lithuanian schools.

The role of an interface between an algorithm and its environment for school students is discussed. The motivation of the use of Pascal functions and procedures instead of commonly used programs in the first lessons of programming is presented. The main features of an interpreter of algorithms (Pascal functions and procedures) implemented on school computer are presented.
