### Description

CMP: Contemporary physics and modern physics at school

We present an overview of demonstration material used in quantum physics education. Our study categorises over 400 articles, covering experiments and demonstrations for quantum education from 1970 to now. Common research questions or goals of studies on demonstration material are identified, together with the number of studies per quantum physics topic. We share insights from studies regarding...

This study examines the conceptual understanding of the scientific principles of climate change of German A-level students using the CCCI-422 climate change concept inventory. The sample under investigation consists of 501 A-level students of five German upper-level secondary schools (Gymnasium) representing the complete A-level student body in their schools. Results show that the CCCI-422...

Wave-particle duality is included in many high school physics curricula as a concept central to quantum physics. However, whether wave-particle duality can be taught effectively depends on the students’ notions of the classical concepts of waves and particles and the ability to apply these concepts in modelling the physical world. Using a questionnaire on these concepts, we investigate the...

One of the key points for understanding quantum physics is the measuring process. In the context of modern approaches to quantum physics via two-state systems, the question of tools for assessing students’ understanding and identifying learning difficulties in quantum physics arises anew. As a first step towards a comprehensive concept inventory, a questionnaire to inquire the student’s...

In this research, we focus on undergraduate physics students’ hybrid views in two specific cross-cutting concepts in quantum physics, namely, wave function and measurement, and examined them in an international context, Italy and Türkiye. Our results indicate a weak association with the country of origin, whereas hybrid views are independent of the targeted concepts.

One amazing characteristics of quantum algorithms is how they can deliver results with 100% certainty despite their structure being based on the probabilistic interpretation of quantum mechanics. This type of algorithm requires a different way of thinking and sets a challenge for science educators. Two routines to emulate quantum cryptography protocols (BB84 and EK91) are proposed in this...

There is an effort on introducing quantum computation into education. In the last years, these were mainly addressed in advanced master’s degree courses for physicist and computer scientist, but the experiences in secondary schools are quite few. I am presenting here a pilot project regarding teaching/learning quantum mechanics via polarisation approach extended with the basics of quantum...

Multi-representations are fundamental to improve the conceptual learning of abstract topics (such as mathematical aspects), allowing students to actively manipulate concepts and instruments which would otherwise be difficult and little accessible. In this presentation we will show different (and interconnected) representations for the acquisition of the basic mathematical formalism of Quantum...

Using models in the physics classroom allows students to explore phenomena in ways that could help facilitate learning. A laboratory exercise was developed where upper secondary school students worked with a mechanical Paul trap and a simulation to understand how a real Paul trap works to investigate the usefulness of ideal models in the physics laboratory for learning. A design-based research...
