Routes to Increasing Ecological Validity in Educational Research

Summary/Abstract: The paper concentrates on problems linked with validity of ex post facto and experimental research in education. It describes the largest stumbling points in interpretation of ex post facto and experimental research findings and then it substantiates the need of their interconnection. Two manners of connecting ex post facto and experimental research are proposed as well as their practical realisation in research projects are presented.
