About

After working as a maths teacher and school principal, I completed my second Masters' degree on Educational Technology in the University of Twente, the Netherlands in 1997. Since then, I have been working as a lecturer, researcher and senior researcher in Tallinn University, Centre for Educational Technology, fulfilling the role of its director from 1999 til 2013. Since 2021, I am a tenure track professor in mathematics and computing education in the same centre. My research interests are: digital competence modelling and assessment, pedagogy-driven and interoperable online learning platforms and tools, learning resource repositories, computing education (curricula, textbooks, teacher education), design of flexible learning and learning analytics. I am a Management Board Member in ICEM, EDEN Digital Learning Europe and also in a Finnish teacher training company Euneos OY.

Metrics description
h-index
A scientist has an h-index if h of his N publications are cited at least h times each, while the remaining (N - h) publications are cited no more than h times each.
i10-index
The number of the author's publications that received at least 10 links each.
m-index
The researcher's m-index is numerically equal to the ratio of his h-index to the number of years that have passed since the first publication.
o-index
The geometric mean of the h-index and the number of citations of the most cited article of the scientist.
g-index
For a given set of articles, sorted in descending order of the number of citations that these articles received, the g-index is the largest number such that the g most cited articles received (in total) at least g2 citations.
w-index
If w articles of a researcher have at least 10w citations each and other publications are less than 10(w+1) citations, then the researcher's w-index is equal to w.
