Additional Information

My CRIS profile

Judith Gal-Ezer is Professor Emerita of Computer Science at the Open University of Israel (OUI), within the Department of Mathematics and Computer Science. 

As faculty, she has developed numerous textbooks in Mathematics and Computer Science (CS) and played a pivotal role in designing both the undergraduate and Master programs in CS. During her time at OUI, she held various leadership positions, including Head of the Mathematics and Computer Science Department, Head of the Development Division, and Vice President for Academic Affairs, spanning almost a decade.

While initially she engaged in research on wave propagation and seismology, her focus gradually shifted to two key areas: computer-integrated mathematics education and computer science education, which has since become her primary interests.

In addition of writing Hebrew textbooks for the Open University Professor Gal-Ezer published tens of publications in professional journals and professional conferences. She supervised many students' seminar works, and Master and PhD students.  

Her involvement with educational policy extends beyond academia. She was member of the Ministry of Education's professional committee responsible for formulating the CS curriculum for Israeli high schools. Subsequently, she chaired this committee and served on similar committees for elementary, middle school curricula.

Furthermore, Judith has contributed extensively to higher education governance, serving as a member of the CHE Council for Higher Education, the regulatory body overseeing all higher education institutions. Presently, she continues to participate in numerous sub-committees of the Ministry of Education, the CHE, and the PBC (Planning and Budgeting Committee).

Professor Gal-Ezer is actively engaged in professional societies and initiatives. She serves on the editorial boards of several prominent journals; she is a member of the Informatics for All European Coalition, and plays key roles in various committees, including the CC2020 Steering Committee and the ACM Education Board. Notably, she chairs the ACM Europe Council Education Committee.

Her contributions to CS education have been recognized through 
prestigious awards, including the ACM SIGCSE 2007 "Special Contribution to
Computer Science Education," the IEEE 2015 Computer Society Taylor L. Booth
Education Award for outstanding research and practical application in the field, and
the 2017 ACM Karl V. Karlstrom Outstanding Educator Award. In 2021 she was also
honored to be recognized as an ACM Fellow. In 2022 she was invited as Fellow of
AAIA (Asia -Pacific Artificial Intelligence Association) and in 2024 as AIIA Fellow (International Artificial Intelligence Industry Alliance).

After several years of research work on wave propagation and seismology, and after completing my M.Sc. and Ph.D. studies, I chose to turn to a different topic and concentrate on educational research in two of my favorite areas: the teaching of computer-integrated mathematics; and computer science education.

My research of computer-integrated mathematics centered on the computational aspects and an algorithmic approach to the teaching / learning of various topics in mathematics. The highlight of this research was the presentation of central mathematical subjects based on elementary knowledge only, and the use of the computer's potential. The motto was that the best way to learn a subject is to teach it to someone else, and even better is to teach it to a computer. The originality of these studies is expressed, among other things, in the presentation of proofs other than existing ones, by means of simple mathematical tools, renouncing a certain measure of generality but without giving up the rigor of rules.

Computer Science education  is now my research focus. It includes issues such as algorithmic thinking, the teaching of difficult and problematic subjects such as recursion, complexity and efficiency, misconceptions in computer science, reduction and non-determinism. A relatively new subject is using educational platforms, such as Plethora for the introduction of algorithmic thinking into elementary and middle schools. Data Sciences is also one of my new research interests. In addition, I am involved in, and sometimes lead the development of national study programs at different levels (universities and secondary schools), and the development of study programs for teachers of computer science.
For a few years I am deeply involved in designing curricula framework for introducing computer science into European schools, trying to convince the EU to adopt this as one of its competencies, and also the PISA science framework team.

While the above are the main issues of my research I did not neglect studies related to the integration of technologies into distance education and computer science distance education in particular.

  • Coordinator, Computer Science team: This task included building up the field of computer science studies: designing curricula, developing courses, recruiting assistants and faculty, recruiting writers, engaging advisors, managerial responsibility of the development and instruction team, monitoring development and teaching, advising students, strengthening ties with colleges (in the field of computer science) and monitoring computer studies in these colleges.

    Head, Academic Development Division: This included responsibility for the academic development of all subjects, managerial responsibility for course development teams (some 150 team members), initiating and concluding agreements with writers and advisors from the academic community, and more.
    The crowning point of my activities in this office was designing a curriculum for M.Sc. studies in computer science and its presentation to the Council for Higher Education. This was the first graduate program offered at the Open University of Israel.

  • This Professional Committee for Computer Studies in High School has designed a computer science study program for secondary schools and supervised the preparation of learning materials and the integration of the program into Israel's education system. This program is considered worldwide as a breakthrough in the field of computer science curricula in high schools. The committee is currently designing and piloting curricula for elementary and middle school students.
