Our research, supported by the Public Education Development Research Programme of the Hungarian Academy of Sciences, will result in several new collaborative research projects. One of them is in the field of teacher training, on the topic of developing mathematical thinking through experience-based learning in the kindergarten and primary school. On 29 April, we held a special workshop with the participation of lecturers and the Rector of the Apor Vilmos Catholic College involved in this topic. The solutions we presented met the ideas of the rector and the lecturers, and we hope to start a research collaboration involving the Catholic Schools Authority of the Diocese of Vác.
