Alexei (also Aleksei, Alexey, Aleksey) L. Semenov (also Semyonov, Semёnov) (Russian: Алексей Львович Семенов; born 1950) is a Russian mathematician, educationalist, Academician of the Russian Academy of Sciences, Academician of the Russian Academy of Education, Head of the Department of Mathematical Logic and Theory of Algorithms, Lomonosov State University, Professor, and Dr. Sc.




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 in 1972. He completed a Candidate of Sciences in Physics and Mathematics degree (Moscow State University in 1975 under scientific advisor Albert Muchnik. His dissertation was titled «On definability in some decidable theories». He also received a Doctor of Sciences in Physics and Mathematics from Steklov Institute of Mathematics in 1984, with his dissertation titled «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, and education.




= Mathematics

=
His major field in mathematical logic is definability theory. He is well known for his decidability results, Cobham–Semenov Theorem, symbolic dynamics applications, and lattices of definability descriptions. His student Andrey Muchnik solved Michael O. Rabin's problem, posed at the International Congress of Mathematicians in Nice. Muchnik and Semenov solved a problem of Andrey Kolmogorov from his work originated descriptive complexity theory. He also contributed to the foundations of the theory of algorithms and theory of randomness.
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 in the group of Dmitry Pospelov. He participated in the last Soviet attempt to construct a supercomputer in 1986. In the last years he developed a concept of individual extended by digital instruments and media. The concept furthers the vision of Lev Vygotsky, Josef M. Feigenberg, Sherry Turkle, Andy Clark and Michel Serres 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. His educational philosophy is rooted in the “learning-by-doing” method of Robert Lee Moore, Paul Halmos, and Russian mathematical circles constructionist approach of Seymour Papert.
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. This includes, but is not limited by, numerical (arithmetic), priority of solving problems-not-known-how-to-solve over drill-and-practice, and using computer for all routine tasks.
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). Later he was the leader of the authors' teams for textbooks in mathematics and computer science for primary and secondary schools.
In 1987, following his work in the Academy of Sciences, he originated a not-for-profit Institute of New Technologies (INT) 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, 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.
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".
In 2017–2019, he led design and implementation for a system of resultative education (personalized competence-based learning) for Russian schools.
In 2019, Alexei Semenov organized a 3 year Program «Fundamental Scientific Support for the Digitalization of General Education» in Russian Foundation for Fundamental Research. As a result of the expert selection, 62 teams from 12 regions of Russia received financial support. "Charter for the Digital Way of School" (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 complete problem-solving 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-audio-text, as recording the first memory of the eldest in the family), etc.




Teaching and Research Positions


He taught at the Moscow school No. 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.
He was the 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.
He was the President and CEO (Rector) of the Moscow State Pedagogical University (2013–2016) – the leading teacher-training institution in the country.
He is the Director of Axel Berg Institute of Cybernetics and Educational Computing FRC CSC Russian Academy of Sciences (2015 – now).
He is the Head of the Department of Mathematical Logic and Theory of Algorithms MSU Faculty of Mechanics and Mathematics (2018 – now).
He is the Senior expert at the Institute of Education of Higher School of Economics (Moscow) (2017 – now).
He was the Editor-in-Chief of the «Kvant magazine» (2012–2018). He was also the Editor-in-Chief of the journal Doklady Mathematics (from 2021). He served as invited editor to volumes of Theoretical Computer Science and MDPI – Mathematics (2022, 2023) (see List of MDPI academic journals.)
He is the author of over 200 scientific papers in mathematics, computer science and education.
