The monograph discusses the educational insights of the IVth form (10-11 year) learners Mathematical competence conception and the theoretical assumptions of the information technology application in teaching Mathematics in primary school, peculiarities of using the computer for teaching (learning) of fourth-formers in home and school environments and basically positive impact of the ICT integration into Mathematical competence development (self-development) process by three distinguished Mathematical education content fields and two learners cognitive ability groups (in particular for boys). Based on the survey results, the model of the IVth form (10-11 year) learners Mathematics teaching (learning) environments enriched with the ICT is constructed, and the links between the factors related to computer use and learners achievements in Mathematics as well as the attitude towards learning it are defined.

Doctor of Social Sciences (Educology, 2013), Lecturer of the Department of Mathematics, Lithuanian University of Educational Sciences, with almost 30 years of teaching experience, interested in Mathematical education in secondary and higher education establishments, ICT integration into Mathematical education and its impact on learners' results.
