Early life and education

Alexei Semenov was born in 1950 in Moscow to a family of electronic and computer engineers. He graduated from Moscow school No. 7 and the Faculty of Mechanics and Mathematics of Lomonosov Moscow State University (1972). He completed Candidate of Sciences in Physics and Mathematics degree (Moscow State University, 1975, scientific advisor ― Albert Muchnik, dissertation «On definability in some decidable theories»), Doctor of Sciences in Physics and Mathematics degree (Steklov Institute of Mathematics, 1984, dissertation «Logical Theories of One-place Functions on Integers»).

Career and Research

Semenov conducted his research in the field of mathematical logic, cybernetics, theoretical computer science, artificial intelligence, education.

Mathematics

His major field in mathematical logic is definability theory.[1] He is known for his decidability results,[2][3] Cobham – Semenov Theorem,[4] symbolic dynamics applications,[5] lattices of definability descriptions.[6][7] His student Andrey Muchnik solved Michael O. Rabin problem, posed at International Congress of Mathematicians in Nice.[8][9] Muchnik and Semenov solved[10] a problem of Andrey Kolmogorov from his work originated descriptive complexity theory.[11] He contributed also to the foundations of the theory of algorithms and theory of randomness.[12][13][14][15]

Among other his students are Alexei Lisitsa, Yuri Pritykin, Tatyana Starikovskaya and Vladimir Vovk.

Computing and AI

Semenov started work in practical computing at age 14 in cooperation with his mother, specifically in speech recognition[16] in the group of Dmitry Pospelov. He participated in the last Soviet attempt to construct a supercomputer in 1986.[17] In the last years he developed a concept of individual extended by digital instruments and media.[18] The concept elaborates vision of Lev Vygotsky,[19] Josef M. Feigenberg,[20] Sherry Turkle,[21] Andy Clark[22] and Michel Serres[23] to the educational context of mass school.

Education: Theory and Implementation

Alexei Semenov’s theoretical and practical work in education originated in his involvement as a student, and later, as a teacher in the Nikolay Konstantinov’s math schools.[24] His educational philosophy is rooted in “learning-by-doing (mathematics ao)” of Robert Lee Moore[25] and Paul Halmos[26] and Russian mathematical circles[24] constructionist approach of Seymour Papert,[27] see also[28] of London Knowledge Lab.

Prof. Semenov's approach to learning and teaching math and computer science in primary school is based on Inquiry-based learning, mathematical experimenting by learners, language development, emphasizing visual (on screen and paper) and palpable (manipulatives, moving objects) environments of strings, bags, tables, games, and robots as the basis for all math, including, but not limited by, numerical (arithmetic); priority of solving problems-not-known-how-to-solve over drill-and-practice, using computer for all routine tasks.[29][30][31][32][33][34][35][36]

In 1985 he was the organizer and co-author of the first computer science textbook for all Soviet schools (editor and co-author – academician A. P. Ershov).[37] Later he was the leader of the authors' teams for textbooks in mathematics and computer science for primary and secondary schools.[38][39]

In 1987 following his work in the Academy of Sciences he originated a not-for-profit Institute of New Technologies (INT),[40] that introduced the constructionist philosophy into Russian schools and started cooperation of INT and other Russian educators with Papert's group at MIT Media Lab,[41] Blagovest Sendov's Problem Group on Education at Bulgarian Academy of Sciences, Robert Tinker's group at TERC, LCSI, Key Curriculum Press. So INT produced Russian adaptations, learning and teaching materials for Logo, educational LEGO, Geometer’s Sketchpad, etc.[42]

Semenov initiated and led in cooperation with Sergey Soprunov the project of Logo-style learning environment for pre-literacy pre-numeracy children, recognized by S. Papert in his book "The Connected Family".[43][44][45]

In 2017–2019 he led design and implementation for a system of resultative education (personalized competence-based learning) for Russian schools.[24][46]

In 2019 Alexei Semenov organized a 3 year Program «Fundamental Scientific Support for the Digitalization of General Education» in Russian Foundation for Fundamental Research.[47] As a result of the expert selection, 62 teams from 12 regions of Russia received financial support. "Charter for the Digital Way of School"[48] (2021) is one of the outcomes created as part of the work on the program as a result of a dialogue between the participants of the Program and other prominent figures of Russian education.

In 2021 he started a Master's Program at Moscow State University on AI and Digital Technologies. In 2022 he reorganized the basic undergraduate course on Mathematical logic and theory of algorithms as a copletely problem-solvibg course in the style of Paul Halmos.

In 2022 Alexei Semenov became the leader of compiling the New Russian Mathematical Encyclopedia as a source for digital Great Russian Encyclopedia, where he became a vice-chairman.

In 2022–2023 he initiated a project of primary school meta-subject "Future World". In all school subjects students are introduced to the future by doing its pieces now in such modules like "Introduction" (children to each other, to the teacher, the tablet, and network), "Organization" (keeping myself in time), "Communication" (video-aidio-text, as recording the first memory of the eldest in the family), etc.

Teaching and Research Positions

Taught at the Moscow school №7, Andrey Kolmogorov boarding school at Lomonosov Moscow State University and at the Department of Mathematical Logic Faculty of Mechanics and Mathematics at Lomonosov Moscow State University.

President and CEO (Rector) of the Moscow Institute of Open Education (1993–2013) which was responsible for the professional development, in-service training, guidance and consulting of all 100,000 Moscow teachers. In 2002 he recreated School No. 179 and returned the mathematician and teacher Nikolay Konstantinov to work there.

President and CEO (Rector) of the Moscow State Pedagogical University (2013–2016) – the leading teacher-training institution in the country.

Director of Axel Berg Institute of Cybernetics and Educational Computing FRC CSC Russian Academy of Sciences (2015 – now).

Head of the Department of Mathematical Logic and Theory of Algorithms MSU Faculty of Mechanics and Mathematics (2018 – now).

International Activities

Alexei Semenov participated in numerous international activities of mathematical and ICT educators.

Alexei Semenov's vision was supported and disseminated by UNESCO with the help of recommendations for primary education[49] as well as for general education.[50] Later he participated in the teams led by Ivan Kalaš, that created recommendations for preschool education[51] and primary education.[52] He participated in the creation of UNESCO recommendations on ICT for teacher education.[53] Prof. Alexei Semenov's activities and influence were recognized by UNESCO Prize on ICT in Education.[54]

Alexei Semenov was the national coordinator of Second Information Technology in Education Study: SITES 2006,[55] member of International Task Force on Teachers for Education 2030, etc.

In 1989 he initiated and played a critical role in the return of international organization on technologies in education ORT (originated in StPetersburg in 1880) into USSR and Central Europe, serves as a member of Board of Trustees and co-chair of Academic Advisory Council of the organization.
