Students' attitudes toward science are complex phenomena depending on numerous factors. The factors studied in this work are students' interest in science, their enjoyment of science lessons and career interest in science. Our objective was to investigate the attitudes of students based on these factors. The main question was whether the students enrolled in a bilingual vocational secondary school for chemistry, environmental protection and information technology had chosen the institution and their professional field according to their personal interests and whether this interest was independent of age and gender. Surveys were conducted in two academic years (2015-2016 and 2017-2018) among students from grade 0 or 9-12. Three factors of the Test of Science-Related Attitudes (TOSRA) questionnaire and self-constructed questions were used and analysed in our research. The results for the self-composed factors of our questionnaire provided evidence to state that the choice of school and that of profession is based on personal scientific interest of students. We have found a negative relationship among TOSRA items and age; regarding gender, there are differences among chemists and IT specialists.

Food supplement use can have beneficial and detrimental effects, making informed decisions about supplement use important. How these decisions are made and which communication strategies can stimulate informed decision making is unclear. This study identified the important characteristics of (i) informed decision making about food supplement use and (ii) important factors indicating how to communicate about food supplements to foster informed decision making. An online three-round Delphi study was conducted. International experts within the field of (risk) communication about food supplements or related fields were recruited via email. The participants' age ranged from 25 to 69 years, and sample sizes for the three rounds were 38, 89 and 51, respectively. Experts indicated that for making an informed decision about food supplement use one needs to have knowledge of their positive and negative effects, the ability to compare these effects, knowing alternatives besides supplements, feeling informed, and feeling able (self-efficacious) to make the decision and making the decision voluntarily. Important communication strategies mentioned were: provision of information about positive and negative effects and the nature of these effects including scientific evidence, ensuring information is easily accessible, well ordered, tailored and provided by a trustworthy, credible and independent source.
