RESEARCH METHODS
To inquire into the motivational and developmental effect of IBSE on giftedness in science education, we used the method of design-based Science Education International 22 research. This developmental research differs from other types of research. The main advantage of design-based research is its close connection with educational practice and its focus on the creation of a new product. We also used other sufficient research methods within the framework of design-based research: questionnaires, interviews, portfolios and collaborative action research based on ICT (Trna & Trnova, 2010; Trnova, 2010).
