The Program “Reflexion 1”—the Condition of Intensive Formation of Metacognitive Skills in Elementary School

Metacognitive skills associated with reflexive actions in solving problems are an essential condition for the successful mastering of school programs and a strong indicator of the intellectual development of primary school-aged children. The purpose of this empirical research is to study the influence of the author’s program of non-educational content, “Reflexion 1”, on the formation of reflexive actions in solving problems for children aged 9 years. Thirty-two classes were conducted (once a week, outside school hours) with the experimental group of students from September to May, according to the specified program. The results show that the lessons in the “Reflexion 1” program contribute to a significant increase in the number of children aged 9 years with substantial reflexive actions in solving problems.
