The rapid pace of technological development enables a wide range of digital tools for teaching. But which ones are effective from a scientific point of view? A meta-analysis by Hillmayr et al. (2020) categorizes existing types of tools. It examines how they affect learning performance in mathematics and science teaching and students' attitudes towards the subject.

The metaanalysis found that there is a significant effect of digital tools compared to lessons without these tools, both in terms of learning performance and students' attitudes. In addition, the effectiveness of the tools is significantly improved if teachers have been trained explicitly in them beforehand. Dynamic mathematical visualisations and (intelligent) digital tutors tend to have particularly positive effects.
