MITU – Mannheimer Inventar zur Testung der Urteilsakkuratheit

Karina Karst and Meike Bonefeld developed the inventory. MITU is a virtual classroom with 16 students of the 2nd grade. Participants can inform oneself about achievements and other students’ characteristics. The tool is especially useful to review how students’ characteristics affect teachers’ judgment accuracy. In addition, MITU can help to gain insights into the process of judgement. Follow the link to get access to the MITU-documentation.
