Teaching of computer programming by electronic mail has been held in Lithuanian schools since 1992. School students of upper grades (8–12) took part in the experiments. The experiments showed that students cope better with first stages of programming (specifying the problem, etc.) than with the last ones (programming, debugging). The analysis of programming products (made by their peers) by students themselves may be expected to be an important component of learning and teaching.

A classification of teaching forms is introduced. One-to-many (group) distance teaching forms are discussed with respect to the means, which are used in the programming teaching process. The role and the possibilities of electronic mail in this process is discussed. The experience of Lithuanian Young Programmers' School by Correspondence is referred to.

An algorithm testing methodology used in the programming teaching process is presented. Turbo Pascal system is used. Due to systematic use of some features of this system a pseudo-direct execution of algorithms expressed by Pascal procedures and functions may be ensured. The need to use data read and write statements is excluded. This enables a novice learner to concentrate himself on the main actions of an algorithm.

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.

The role and goals of computer programming in the education of young people are discussed. The activity of the Lithuanian Young Programmers School by correspondence is described. Motivation of its curriculum and the way of teaching are given. Relations with the competitions of programmers and some other forms of teaching are considered.
