“…We focused on analyzing the appropriateness of E-learning materials for presenting topics related to liquid crystals at different levels of education: for primary and secondary schools and for students of physics in educational and engineering study programs. We found in our comparative study of comprehension of both approaches for two groups of students, those unfamiliar and familiar with LCs, that students with experience in this field prefer the use of 2D views, while other students are significantly worse in interpreting 2D views [10]. In our opinion, there is neither an advantage or disadvantage to using 2D static (web pages with a large amount of information: mostly text, images, formulae etc.)…”

“…These simulations are suitable for all levels of learning because they allow the student to better imagine the phases and defects of liquid crystals it in three dimensions (3D). Our comparison of static and dynamic components in elearning materials on the topic of liquid crystals was made with a particular focus on the learning effectiveness of two dimensional (2D) and 3D presentations [10]. The main finding was that a 2D representation (using different cross-sections) of a physical 3D system is preferable for experts in the field since the proper 2D visualization gives more concise information than the 3D view.…”

Physicists research numerous interesting physics problems, among them the behaviour of liquid crystals. These problems can be very useful for illustrating general principles of physics, and so we worked to include them in our natural science program. In the frame of a project entitled "Introduction of current research interdisciplinary topic into education -liquid crystals" we prepared static and dynamic components for e-learning materials to highlight some of the key properties of typical liquid crystalline phases and some structures that appear in different geometrical boundaries or in bulk systems. The materials produced, and an analysis of the appropriateness of different types of e-learning materials for different levels of education (including primary education, secondary education, and physics courses for educational and engineering studies) are described in this article.

Abstract. The paper presents a teaching module about liquid crystals. Since liquid crystals are linked to everyday student experiences and are also a topic of a current scientific research, they are an excellent candidate of a modern topic to be introduced into education. We show that liquid crystals can provide a file rouge through several fields of physics such as thermodynamics, optics and electromagnetism. We discuss what students should learn about liquid crystals and what physical concepts they should know before considering them. In the presentation of the teaching module that consists of a lecture and experimental work in a chemistry and physics lab, we focus on experiments on phase transitions, polarization of light, double refraction and colours. A pilot evaluation of the module was performed among pre-service primary school teachers who have no special preference for natural sciences. The evaluation shows that the module is very efficient in transferring knowledge. A prior study showed that the informally obtained pre-knowledge on liquid crystals of the first year students on several different study fields is negligible. Since the social science students are the ones that are the least interested in natural sciences it can be expected that students in any study programme will on average achieve at least as good conceptual understanding of phenomena related to liquid crystals as the group involved in the pilot study.
