Abstract

The operationalization of a research problem is a constitutive stage of the process of implementing any scientific research. However, carrying operationalization out is a challenge for the researcher, because it requires good, complete, and up-to-date knowledge of the analyzed issues. Therefore, researchers are increasingly encouraged to look for ways or procedures that make it possible to search, clarify, and understand in a multi-aspect manner phenomena that may become the subject of empirical research. This is particularly important in the context of research on higher education, which requires a qualitative approach. Crowdsourcing in science has entered the popularization phase and seems to be promising in the context of the operationalization of any research problem. The aim of this article is to present a proposal for the use of crowdsourcing in science as an auxiliary (supplementary) procedure at the stage of the operationalization of the research problem and to consider its effectiveness in the context of research on higher education.
