The purpose of this study is to develop targeted storytelling techniques for risk group children for curriculum-oriented moral education in Self-cognition classroom, to diagnose children for the purpose of curriculum development, and pilot-test the curriculum in classroom. The study involved 102 6 th grade schoolchildren at Almaty based School 52 (aged 12). The following diagnostics tools were used: the Melnikov-Yampolsky Conscientiousness Scales, the Ilyin Method of Conscientiousness Analysis.
