This paper explains design decisions forming a foundation of WordBricks — an intelligent computer-assisted language learning environment, recently initiated at our institution. WordBricks is intended to serve as a “virtual language lab” that supports open experiments with natural language constructions. Being based on dependency grammars, this instrument(More)
In this paper, we briefly describe the limitations of present CALL systems, caused both by technological factors and by the limited agenda of CALL developers, whose design goals tend not to result in software tools for practical everyday language learning activities. We also note the lack of creative new ways of using computers in language education and a(More)
The nucleotide sequences of nuclear gene EF-1α were determined for 49 species of Lasiocampidae from Eurasia and Africa. Based on these data, the phylogeny of the family was reconstructed using the minimum evolution, maximum parsimony, maximum likelihood, and Bayesian inference methods. The molecular genetic research confirms the monophyly of Malacosominae(More)
