The purpose of the article was to analyze the psychological and pedagogical conditions of word-formation skills for Kazakh-speaking preschool children with speech disorders on the basis of learning theories and contemporary approaches. To achieve the set aim, we have studied psychophysiological peculiarities of preschool children with speech disorder. We have allocated the most significant learning theories and approaches, which promote the assimilation of word-formation. We have come to understand that the indicators of speech development of many modern Kazakh-speaking preschoolers do not correspond to the age norm, which is influenced by word-formation operations. For Kazakh-speaking preschool children with speech disorders it is rather difficult to distinguish elementary forms as the original word, consisting of a stem and a derivative by including diminutive-affectionate suffixes. The driving forces of word-formation development of Kazakh-speaking preschoolers with speech disorders are contradictions that arise in connection with the development of a number of its needs. It should be pointed out that game technology is considered as the most powerful pedagogical condition in the development of Kazakh-speaking preschool children with speech disorders.
