Its members publish approximately 10,000 publications annually and participate in over 2000 scientific programs. AUTH supports research projects in various disciplines and houses the Physics Department, established in 1928, as part of the Faculty of Sciences. Renowned for its academic excellence in both faculty and student numbers and research programs and projects, the Physics School is one of the university's oldest, largest, and most important schools. The School aims to lead in research, provide high-quality education, and prepare students for advanced work and direct employment in the field of physics. Therefore, the Physics School commits to continuously improving its curriculum, laboratories, and research facilities and collaborates with national and international agencies and institutions to achieve common goals. The academic, research, specialized scientific, and specialized laboratory staff of 103 members contribute significantly to Science Education within the Physics Department. At the undergraduate level, it offers four relevant courses and hosts a graduate program in Physics Education and Educational Technology. The Physics Department's Science Education and Educational Technology Laboratory (DiPhET) aims to apply best practices in Physics Teaching and Learning and Educational Technology according to the latest technology, contribute through research, and make these beneficial for the professional development of department students (at undergraduate and graduate levels) and in-service educators. The DiPhET Laboratory engages in activities such as designing/implementing/evaluating Teaching and Learning Sequences in various Physics topics, aiming to equip students with 21st-century skills. With extensive experience in Research-Based Learning, Project-Based Learning, STE(A)M, Computer-Based Experiments (Simulations, Virtual Laboratories, Real Laboratories with Sensors, Remote Laboratories), the laboratory has transitioned to mobile learning in recent years. Over the years, the DiPhET Laboratory has established a network consisting of collaborating schools in Middle and Lower Secondary Education where educational innovations developed in the laboratory are implemented and evaluated.
