The aim
of the study was to determine the conditions for the improving of combinatorial
actions in children of 9 years old (3rd grade 9 years old elementary
school students). The original «Combination-2» educational program may become a
condition for improving combinatorial actions. It was supposed to establish
such conditions. The program includes 30 types of non-standard tasks with
extracurricular content. Each type of task had three structural versions of the
tasks: find the answer, find the question, find part of the initial conditions.
Solving these problems requires combinatorial actions. The control group
consisted of 91 children, the experimental group — of 96. These children
participated in 30 group classes for 30
weeks (weekly, from September to May).
The study showed that the “Combination-2” lessons contribute to the
improving of combinatorial actions in children. In further studies, it is
planned to determine the extent to which the “Combination-2” program
contributes to the improving of combinatorial actions in children of 10 years
old.
