@misc{Nieścioruk_Julia_Istotne, author={Nieścioruk, Julia}, howpublished={online}, publisher={Zielona Góra: Oficyna Wydawnicza Uniwersytetu Zielonogórskiego}, language={pol}, language={eng}, abstract={It is undeniable that a wide variety of factors, both learner-internal and learner-external, influence the rate and level at which a language is mastered. From the two groups of factors, selected ones are presented, from learner-internal: well-being and foreign language enjoyment, and from learner-external: peer environment and relationship. The definitions of these factors are followed by a discussion of their correlation with other positive psychology factors and existing research results.}, abstract={As the given scientific sources indicate, there is a positive correlation between the indicated factors and foreign language proficiency and achievement. References were made to selected theories from the field of positive psychology as well as to the perception of foreign language in the context of Complex Dynamic Systems Theory, which treats language as a thriving, intricate and extremely dynamic structure. Furthermore, the article identifies the important role of parents, teachers and peers in the foreign language acquisition/learning process. Thus, the paper provides implications for future educational practice; it points to the need for foreign language teachers to refine their educational programmes and deepen their competences, especially their social competences, so that they can effectively and adequately support their students with diverse needs}, type={rozdział w książce}, title={Istotne czynniki warunkujące poziom opanowania języka obcego}, keywords={radość z nauki języka obcego (FLE), determinacja, dobrostan psychiczny, psychologia pozytywna w nauce języków obcych, teoria złożonych systemów dynamicznych (CDST) w nauce języków obcych, środowisko rówieśnicze, relacje z rówieśnikami, foreign language enjoyment (FLE), well-being, positive psychology in foreign language learning, Complex Dynamic Systems Theory (CDST) in foreign language learning, peer environment, relationship}, }
