# Said Hadjerrouit

Said Hadjerrouit is a professor of informatics and computer science at the University of Agder in Kristiansand, Norway. He got a doctoral degree (Dr.Ing) in 1992 in the field of medical expert systems and artificial intelligence, and a master's degree (1985) in software engineering from the Technische Universität Berlin, Germany. His teaching in Berlin focused mostly on informatics and society, philosophical and ethical issues of computing, and computers in developing countries. In 1991, he moved from Berlin to Kristiansand, Norway, and worked at the Institute of Electronic Data processing at the University of Agder. In 1994, he moved to the Institute of Mathematical Sciences at the same university, where he was appointed as an associate professor for teaching object-oriented programming, Web engineering, software development, and databases. From 2004, his work shifted to didactics of informatics and computer science education, ICT in mathematics education, ICT-enhanced learning, Web-based learning resources, social software, and Web 2.0 technology. In 2008, Hadjerrouit made a major shift in his research focus from didactics of informatics and Computer Science to mathematics education and use of digital tools in teaching and learning mathematics. He has been teaching the doctoral course “Theories in the Learning and Teaching of Mathematics” since 2014. He is also supervising two PhD students in the field of Flipped Classroom and documentational approach to mathematics education. Hadjerrouit has more than 140 publications in international journals and conference proceedings. He was awarded for Best Paper at Society for Information Technology and Teacher Education Conference (SITE 2010) in San Diego, California, United States, and IADIS e-Society conference 2012 in Berlin, Germany.
Hadjerrouit is leader of PhD committee for Specialisation in Mathematical Sciences (FDM).
Hadjerrouit is a member of the Agder Academy of Sciences and Letters, with members from Agder, Norway, and from abroad. Hadjerrouit is a member of ISI, and editorial review board of JELLO.
