The main purpose of the data literacy development study was to review the content and technical aspects of the test procedure to be used in the first main survey of the BMBF-funded data literacy study in fall 2023. In the run-up to the data literacy development study conducted in fall 2022, nearly 160 tasks on digital and data-related competencies were formulated.
These tasks were each presented to participants in the development study in excerpts, with each person completing about 80 tasks in 80 minutes, if possible. There was systematic variation in which tasks were presented in each case; the order of the tasks was also varied. A total of 240 persons aged 10 to 69 years participated in the development study. The average age of the participants was approximately 30 years. In addition to questions on digital and data-related skills, the development survey also included questions on self-assessment, use of data in work and leisure, interest in digital and data-related content, and an effort thermometer. Furthermore, the survey asked how useful and trustworthy participants considered science to be.
Overall, the participants in the data literacy development study performed quite well in the tasks. Very many of the tasks were solved correctly by many people. The results of the development study were used to select around 80 tasks that will be presented to a representative sample of the German population in fall 2023.
The evaluation of the remaining data is still pending. Specifically, the relationship of digital and data-related competencies to attitudes as well as gender differences in competency and self-assessment will be investigated.
LIfBi and the project team would like to thank all participants of the Data Literacy Development Study for their assistance!
