ABSTRACT

The primary objective of the current project was to convey authentic science to students in out-of-school student laboratories. High school students have diverse and partially wrong concepts of scientists’ work. To convey more realistic concepts, we developed videos of scientists working on relevant and up to date scientific topics. These videos, covering different work fields of scientists, were integrated into experimental stations as part of the student lab. Half of the participating students performed the experimental part only (n = 117), whereas the other half of students (n = 119) additionally watched the videos. The results of a pre-post comparison show significant increases for previously underestimated work fields, such as artistic (d = 0.94) and social (d = 0.51) aspects, for the video group. Furthermore, the perceived authenticity in the student laboratory was also promoted by the videos (d = 0.47). In conclusion, videos were shown to be a suitable option to promote the perceived authenticity in out-of-school student laboratories and to convey an authentic concept of scientists` work.

摘要

当前项目的主要目标是向校外学生实验室的学生传达真实的科学知识。高中生对科学家的工作有不同的、部分错误的概念。为了传达更现实的概念，我们制作了科学家们研究相关和最新科学主题的视频。这些视频涵盖科学家的不同工作领域，作为学生实验室的一部分被整合到实验站中。一半的参与学生仅进行了实验部分 ( n  = 117)，而另一半学生 ( n  = 119) 还观看了视频。前后比较的结果显示，以前被低估的工作领域显着增加，例如艺术（d = 0.94) 和社交 ( d  = 0.51) 方面，对于视频组。此外，视频也促进了学生实验室中感知的真实性（d  = 0.47）。总之，视频被证明是一种合适的选择，可以促进校外学生实验室感知的真实性，并传达科学家工作的真实概念。
