Only a few studies have focused on how teachers deal with mistakes in actual classroom settings. Teachers' error management behavior was analyzed based on data obtained from direct (Study 1) and videotaped systematic observation (Study 2), and students' self-reports. In Study 3 associations between students' and teachers' attitudes towards mistakes and their impact on students' domain specific emotions were investigated. Together, the presented studies contribute to the understanding of the interplay between teachers' everyday instructional routines surrounding mistakes and students' beliefs about (learning from) errors. The findings also emphasize the relevance of how students perceive their teachers' attitudes towards mistakes. (Contains 5 figures and 11 tables.)
