Modern research in health, education and social sciences

Throughout its evolution, science has always vacillated between two fundamental aspects (its quantitative and its qualitative aspects). Specialists' concerns have moved cyclically from one aspect to the other. However, never has there been exclusive stress on either quantitative or qualitative issues. Even if an unequally, science have always taken into consideration both aspects, given that the psychological, social, medical, educational or organizational reality cannot be explained in a satisfactory manner by resorting exclusively to either quantitative or qualitative research.
