Tag #132368 - Interview #78789 (Ivan Barbul)

After finishing the postgraduate course I returned to Kishinev where I went to work as a senior scientific employee at the Scientific Research Institute of Pedagogy. I dealt in mathematics teaching methodology. I was involved in the scientific research work. I published a book: 'Elements of geometry in primary school'. In 1968, I defended a candidate's dissertation [see Soviet/Russian doctorate degree] [27] in Moscow.
