摘要:Natural sciences in Slovenia are not as popular as we would like them to be. Biology teaching and learning in great part consist of memorizing the facts and not so much of developing competences. Laboratory and field work are recognized as methods where students can achieve subject specific and generic competences, as recommended by different international organizations. Such key competences are mathematical competence and competences in science and technology, and digital competences. Although competences cannot be learned but have to be achieved, the task seems epical when students can hardly find computer supported didactical tools in their own language. On the Faculty of Natural Sciences and Mathematics virtual biology exercise Mendelian Genetics with a translational tool was developed. Teachers have the possibility to translate it into desired foreign language. Virtual exercise is interactive and encourages the critical thinking approach to reach the high level cognitive skills and development of different competences.
