Development & validation of scientific video vignettes to promote perception of authentic science in student laboratories

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 well-considered/planned videos are one suitable option to promote an authentic overview about science and scientists.
