The most widespread form of education in the field of sign language are the three-cycle courses for teachers of deaf children, organized directly in schools and educational centers, as well as in the summer, in the form of the so-called summer sign language schools that organize education for more people at different levels. Excellent teaching aids are the textbooks published by Wydawnictwa Szkolne i Pedagogiczne (dictionaries and a series of educational videos), such as:
JK Hendzel: Dictionary of Polish Sign Language, Wydaw. “Offer”, Olsztyn 1995; B.Sz Szczepankowski, M. Rona: Scholastic Dictionary of Sign Language; “Vinea” publishing house, Bydgoszcz 1994; The three-part series of instructional films includes 110 features over ten minutes long produced by the Warsaw-based “Dydakta” film studio;
Szczepankowski: Basics of sign language. WSiP, Warsaw 1994, pp. 45-48. Passive knowledge of sign language is possessed by the majority of deaf and deaf people, active knowledge is possessed mainly by the deaf and most deaf people who have graduated from special schools (Szczepankowski B. 1994). However, there are many deaf people who can only communicate using classic sign language.
Mastering this language is much more difficult. Here, it is not enough to learn the signs, it is necessary to understand the spirit of the language: vocabulary, grammar, ways of presenting signs, the specificity of manual spatial communication, containing many rules that do not exist in audio languages, and to learn how to correctly build a expression in sign language. This can only be achieved by staying with the deaf on a daily basis, and the level of proficiency in the language sufficient for free communication is only achieved after several years of constant use in communication.
