EUREKA-Dimarove joint seminar in La Rioja. Rosa Arruabarrena, JoseMi Blanco, Ana Sánchez, Josean Vadillo and Imanol Usandizaga from San Sebastián and Arturo Jaime and César Domínguez from La Rioja participated. We have made a historical review of the various areas in which we have worked and converged in educational research the different assistants of both groups, listing the publications generated, and raised the new future lines that can be addressed, due to the changes that are coming with the imminent retirements of Ana and Josean. The meeting was emotional and profitable, as on previous occasions.
