As mentioned above, it is impossible to identify a most common practice in multi-grade teaching from our study. A similar
result has been found in earlier studies (Little, 2001; Lindström & Lindahl, 2011). One reason for the wide range of practices
could be the lack of multi-grade teaching options in textbooks and curricula, as well as in teacher education (Little, 2001).
Thus, the teachers in our study may have developed their personal teaching styles primarily in practical situations in their
own classes or with the help of their colleagues. Researchers have referred to this type of problem in terms of a divide
between theory and practice, thereby raising doubts about the effectiveness of teacher education in general and suggesting
that new and promising views of learning and teaching could better serve schools (Korthagen, 2010).
