%0 Journal Article %T Five research principles to overcome the dualism quantitative-qualitative %J - %D 2014 %X Th e article intends to suggest some refl ections about the criteria that should guide the design of empirical research and the evaluation of research plans and reports. Th e main idea is to demonstrate that educational research is intrinsically multi-method and mixed-method. Qualitative and quantitative moments are present in all the research and the two approaches are closely interrelated. To overcome a ¡°paradigmatic¡± view that impose the rigid separation between quantitative and qualitative approaches, fi ve research principles are proposed. Th ese principles are related to: a) planning of the research; b) declaration of the theoretical ¡°lenses¡± by which the researcher see (and interprets) the world; c) designing and documenting of the research plan; d) analysis of the data gathered; e) defi nition of the logical extension of the research results. Th e adoption of the illustrated principles is a possible way to promote a new ¡°culture of empirical research¡± in education, based on openness to diff erent theoretical contributions (also from diff erent disciplines), epistemological approaches and operative strategies. A research that aspires to have a decisive impact on current educational practices must be a research able to defi ne not only ¡°what works¡±, but also ¡°how works¡±, ¡°why works¡± and ¡°where works¡±, and only the synergy between the qualitative and quantitative approaches can aid the research to pursue successful these objectives %U http://riviste.unimc.it/index.php/es_s/article/view/926
