Background: Many students have incomplete or incorrect perceptions of science and scientists. These simplified images, mediated by media or influential agents of socialisation, result in common stereotypes. Especially for occupational choices it is important to convey an authentic image about science and scientists. Purpose: One manner to convey an authentic image and thus the aim of this study is the development and validation of scientific videos including collected activities of scientists. Program description: Professors were interviewed regarding their typical scientific activities. This was followed by the development of a questionnaire which was answered by junior scientists. Authentic scientific videos were developed and finally validated in a science lab for school-students based on qualitative and quantitative results. Sample: 92 junior scientists answered the questionnaire and eight professors and 96 students (31 girls and 65 boys; grade 10 to 13) were interviewed. Design and methods: The scientists were surveyed before the development of the videos. The RIASEC+N model was used to categorise the collected activities of scientists. Finally, students were interviewed for the video validation. Results: A number of different scientific activities of each RIASEC+N dimension could be detected, which were then integrated into four videos. The interviewed students who watched those videos successfully identified all of the activities. Conclusion:The working day of scientists contains more than stereotypical aspects and wellconsidered/planned videos are one suitable option to promote an authentic overview about science and scientists.

Some level of understanding of and about nanoscience and nanotechnology (NST) has been suggested as being relevant in up-to-date scientific literacy for all. Research scientists working in these fields are central in current efforts to inform and engage the public in NST. Earlier research has shown that scientists can contribute to authentic science learning, but communication always entails roles that affect the choice of content. This study investigated NST researchers’ views on the nature of their research and their preferences in NST communication. Eight experienced professors working in various fields of NST were interviewed. Semi-structured, in-depth interviews focused on the scientists’ views on 1) the nature of their research, and 2) aspects of NST that should be communicated to the public. Qualitative content analysis of the interviews revealed that the themes the interviewees highlighted when describing their research (interdisciplinarity, size scale, methods, objects, nature of NST in general) were somewhat different from the ones they considered as important for communication to the public (applications and products, risks and benefits, visualizations). The results problematize the simplistic notion that exposure to real scientists would unquestionably enhance the authenticity of science learning. This study gives insight for research and development of science communication, especially scientists’ role and training in it. Keywords: authenticity, nanoscience, nature of science, science communication, scientist interviews.
