    Oral presentation

    Special relativity is a challenging topic for secondary school students due to its abstract and counterintuitive nature. Thought experiments are often used to make relativistic effects tangible. Prior research has shown that students often express thought experiments in intuitive operationalisations, rooted in everyday experiences. We developed and evaluated a three-part lesson series focusing...

    Oral presentation

    Cosmic ray research, a new field in physics and astrophysics, emerged in 1912 [1]. Its deeper understanding became possible through advancements in electronics and detectors. However, it was rarely included in citizen science projects. Our CREDO-edu program aims to change this. We created an app for cosmic ray measurements in schools and homes and developed a year-long school curriculum to...

    Oral presentation

    The reasoning of 64 Greek secondary education students about the nature of electromagnetic radiation and its effects on human health is investigated. The study took place in the context of a teaching-learning sequence on argumentation and climate change. Results indicate that students’ reasoning tended to exploit evidence that was accessible as part of the given scenarios but also prior...

    Oral presentation

    Ionizing radiations are widely used for diagnostic and therapeutic purposes and hence saving millions of lives every year. Over 25 million people in the world living with cancer. Nearly 11 million people are diagnosed with cancer every year and more than 60% of them get curative and/or palliative treatment using ionizing radiations through radiotherapy or brachytherapy or nuclear medicine....
