[full article, abstract in English; abstract in Lithuanian] The article examines the modern computer-based educational environment and the requirements of the possible cognitive interface that enables the learner’s cognitive grounding by incorporating abductive reasoning into the educational process. Although the main emphasis is on cognitive and physiological aspects, the practical tools for enabling computational thinking in a modern constructionist educational environment are discussed. The presented analytical material and developed solutions are aimed at education with computers. However, the proposed solutions can (...) be generalized in order to create a computer-free educational environment. The generalized paradigm here is pragmatism, considered as a philosophical assumption. By designing and creating a pragmatist educational environment, a common way of organizing computational thinking that enables constructionist educational solutions can be found. (shrink)

[full article, abstract in English; abstract in Lithuanian] Many countries are adopting computing in schools, for pupils from 5 years of age. Educational philosophies that such curricula might be based on are not clear in curriculum documentation. Many Western countries’ curricula are based on developmental concepts of cognitive constructivism, with activities progressing through sensorimotor, preoperational, concrete operational, and formal operational stages. Social constructivism and constructionism add new dimensions to this learning framework, both fundamentally important for developing computing practices. We review (...) selected learning theories, and investigate features that should underpin computing curricula if practices and outcomes are to develop computing practitioner competencies of a software developer.
