Abstract
"The article indicates the relevance of the development of students’ ability to reasoned deliberation as an integral component of critical thinking. The authors designate and make an attempt to understand some of the problematic aspects of the development process in students’ ability to reasonably deliberate. It is based on the analysis of the researchers’ existing practical expertise. In particular, the article points out that argumentation skills do not arise automatically under the influence of the learning process, but need targeted shaping and training. It is also noted that in the process of socialization, a person can involuntarily acquire irrational ideas, which impede the formation of reasoning skills and contribute to the emergence of such negative phenomena as «naive rationalism» and «cognitive dissonance». At the same time, the authors designate the development of educational programs based on the principles of rational-emotional behavioral therapy as one of the advanced trends aimed to correct development of argumentation skills and containment of irrational beliefs.
