The Mercator Institute bridges the gap between research, policy-making and practice. It gathers together findings on the effectiveness of concepts, measures and models in language education. "What works?" aims to prepare and disseminate knowledge for specific target groups in various formats.

Research-Based Services
In order for researchers to be able to work in the best possible way, they need appropriate infrastructures. The Mercator Institute maintains various scientific infrastructures and offers research-based services. These include the "research database Lernertexte - FD-LEX", the "reference vocabulary for schools", which will be activated at the beginning of 2023, and "What works?."

Forschungsdatenbank Lernertexte (in German)
The web-based database enables research in a text corpus of 5,628 learner texts in German. The texts were collected in fifth and ninth grades at comprehensive schools and grammar schools. The database is currently being expanded - also in cooperation with the Verbund Forschungsdaten Bildung (VerbundFBD).
