RESUMEN
The research mapped chemistry-oriented university freshman students' ability to solve chemical calculations. Their success was monitored based on several factors such as their faculty, field of studies, the type of calculation and the assignment type (word problem vs. formula). The results indicate a significant need to change the approach to teaching chemical calculations - the students were rather unsuccessful in the tasks. The obstacles they face include the ability to identify a problem, understand the concepts of calculation and appropriately adjust the correct use of the mathematical apparatus. These findings represent an impulse for teaching in upper-secondary school as well as to introductory university courses.

Tasks in Czech lower-secondary chemistry textbooks were analysed to describe their position in textbook chapters, required response type, overall task nature, as well as cognitive requirements. The results showed older textbooks contain task banks at the end of chapters suggest a transmissive teaching paradigm, whereas newer textbooks containing tasks within the chapters. As far as the nature of the tasks is concerned, a strong stereotypical genre was found in the chemistry textbooks. Most of the textbook tasks require open-ended answers and target: factual and conceptual knowledge remembering or procedure application. The authors therefore suggest several changes to the tasks, including their position in chapters, cognitive difficulty as well as the required response type in order to meet chemistry education goals.

OBJECTIVES: Influenza is a widespread respiratory disease with a potentially risky course. Vaccination is considered the most effective method of prevention. However, only a small portion of the population is vaccinated. Teachers work in a high-risk environment and they have a significant impact on the population through student education. Therefore, the aim of this study was to find out the knowledge and attitudes of pre-service teachers about influenza and vaccination. METHODS: A questionnaire survey was conducted to find out what knowledge, attitudes and behaviour pre-service teachers (N = 373) show in relation to influenza and influenza vaccination. It was statistically tested whether there were differences between students with respect to their field of study. RESULTS: The majority of pre-service teachers have a good knowledge of influenza symptoms, however, they often mistaken it for other respiratory diseases. The field of study plays only a partial role in the knowledge. The respondents perceive influenza as an easily spread disease, but they have negative attitudes towards vaccination, and most pre-service teachers think that its disadvantages outweigh the advantages. This was stated primarily by pre-services science teachers. These attitudes are also reflected in the low vaccination rate of the sample (6%). CONCLUSIONS: Relatively good knowledge of teachers is not reflected in their attitudes and behaviour. Negative attitudes towards vaccination are most held by pre-service teachers, whose field primarily includes teaching this topic. It can have a significant effect on students' attitudes not only toward influenza vaccines but also to other vaccinations.
