Datavisions: Teaching in the age of data visualizations

About the project

The growing use of digital learning materials in Danish classrooms has resulted in a proliferation of data. Teachers mainly access these data through visualizations that communicate patterns within data sets. How data visualizations influence teachers’ assessments of students, however, has yet to be systematically researched and analyzed. This project examines the types and consumption of data visualizations in digital learning materials in order to explore if and how they influence teachers’ assessments. Conceptually, the project draws on science and technology studies to theorize data visualizations as socio-technical micropolitics. Empirically, one sub-project explores which types of data visualizations are prevalent in Danish learning materials and to what degree they represent an automation of assessment. A second subproject examines how teachers engage with data visualizations in practice and use them to assess student learning.

PROJECT PERIOD: 01-01-2022 - 31-01-2025.

In order to gain insight from stakeholders and practitioners, interviews, observations and participant-observation will be conducted with schools and EdTech companies. The project also harvest data visualizations from Danish digital learning materials, however, only with dummy data (i.e. no data about students will be stored). 

The project uses the scientific research purposes as legal basis. Pursuant to the General Data Protection Regulation, the project should provide all participants/data subjects with information about how their personal data will be processed. 

All personal data collected for the project will be pseudonymized and stored in accordance with GDPR compliance rules. Personal data is pseudonymized by removing all directly identifying information from the data. A unique serial number will be added within the framework of pseudonymization. The serial number - with an associated separate 'key file' - will make it possible to return to the original person identification. This so-called ‘translation key’ will be stored separately from the pseudonymized data using an Aarhus University-based GDPR compliant solution only made available to the project researchers. Data harvested from interviews, documents, archives, and other sources will be stored on a secure Aarhus university based platform. 

Personal data will not be subject to automated processing and will not be disclosed to others. 

Data from interviews will be pseudonomized in research publications with reference only, in a few instances, to the organization (organizations such as ministries will be referenced, schools and EdTech companies will remain pseudonomized). 

Your personal data will be processed by Aarhus University for as long as required by the research purpose and the rules on storage according to responsible conduct of research. When we no longer need your personal data for processing, the data will be erased. 


Complaints about the processing of personal data should be directed to the supervisory authority:
