Abstract
The paper introduces the phenomenon of e-didactical shift in case of teaching mathematics with the use of information technologies. The term was coined as an analogy to meta-didactical shift defined in the Theory of didactical situations in mathematics.
The phenomenon is illustrated on examples from school mathematics. Its influence on ICT supported teaching of mathematics is analysed and discussed.
The theoretical framework of the Theory of didactical situations is used for both description of e-didactical shift and analyses of its occurrence. In the paper, attention is paid to the possible negative impact that e-didactical shift may have on teaching of mathematics.
