Literature review shows that many primary school teachers have poor understanding of basic astronomy contents. Therefore, the aim of the study was to introduce specific astronomical content to in-service primary school teachers through two didactic games, to evaluate the didactic games and the teachers’ knowledge and understanding before and after the implementation of the didactic games. The research included 24 in-service primary school teachers. The data were collected through the knowledge test (pre-post design) and questionnaires for each didactic game. The results showed that the teachers evaluated the didactic games as suitable for use in the classroom as they emphasized that they are educational, explicit and interesting. The implementation was identified as effective because the median for fractional gains was 0.54 and showed the medium gain in teachers’ knowledge and understanding of selected astronomy contents. It was recognized that in-service primary school teachers do not feel competent for introducing complex astronomical contents to their students. However, the presented approach could encourage in-service primary school teachers to deepen their knowledge and to teach astronomy contents with a method that is closer to their students. University teachers could point out the advantages and disadvantages of didactic games in astronomy content and discuss them with pre-service primary school teachers. Keywords: astronomy education, didactic games, in-service primary school teachers, Moon phases

The purpose of this paper is to explore and explain students’ achievements in solving context-based gas exercises comprising the macroscopic and submicroscopic levels of chemical concepts. The influence of specific variables, such as interest in learning, formal-reasoning abilities, and visualisation abilities, is a significant factor that should be considered when explaining students’ achievements with context-based exercises. Seventy-nine students of three age groups (12, 16, and 23) participated in the study. Questionnaires, tests, and a semi-structured interview including computer-displayed context-based exercises were used to collect data. In addition, an eye-tracker was used to determine the exact location of the participants’ points of gaze. The results show that students on average answered correctly from 40 to 79% of all questions in the context-based exercises. The context-based exercise related to air compression is indicated as being difficult for students. In students’ explanations of different levels of chemical concepts, representation difficulties are detected in all three age groups of students. Students’ achievements in solving context-based gas exercises do not depend on interest in learning chemistry and visualisation abilities. However, statistically significant differences exist in total fixation duration on the correct submicrorepresentation animation between students with different formal-reasoning abilities. The results serve as a starting point for the planning of different context-based exercises and problems comprising the chemistry triplet with 3D dynamic submicrorepresentations.

We present a teaching unit on liquid crystals. The unit has already been implemented into the university undergraduate pedagogical study programs for future teachers of Physics and Chemistry, preschool teachers and teachers at the lower grade of the elementary school at Faculty of Education, University of Ljubljana. The unit develops students’ knowledge on the existence of more than three phases of matter and the existence and properties of anisotropic materials, focusing on the biaxiality and birefringence. The unit is multidisciplinary since students perform the experiments with the MBBA nematic liquid crystal which they synthesize themselves. Our final goal is to implement the teaching unit to the high school curriculum (for students 14–18 years old).

ETwinning is a community of European schools that promotes networking and transnational collaboration projects. Therefore, as part of the Initial Teacher Education (ITE) initiative, we decided to explore how the research projects on scientific topics familiarize pre-service primary school teachers with eTwinning. 251 pre-service primary school teachers from Spain, Iceland, and Slovenia designed and carried out joint research projects on scientific topics. The aim was to gain insight into their self-assessment of their knowledge of the platform, the limitations of working with it, and their responses. An electronic questionnaire was used as the main instrument for data collection. It turned out that the pre-service teachers enjoyed this international collaboration, but also found it challenging. By the end of the projects, they were familiar with the eTwinning platform, although the least engaged prospective teachers recognized that they needed strong support and considered the platform a non-intuitive environment. Overall, they were willing to use the platform with pupils in the future, which is in line with the aim of the ITE initiative.
