There is the restoration of classroom at almost school museum. It is instructive for students to understand the history of the school. But we cannot find the image of teacher there. For example there are 5 classrooms in the National School Museum in Rotterdam: the village school of 1662, the model school in 1830, classroom of 1910, classroom of 1930, classroom of 1960. But there is only one teacher in the village school of 1662 and it is reconstructed from a painting by the famous 17th century Dutch painter Adriaen van Ostade. This picture is able to be seen in the Louvre. There are 3 classrooms in the School Museum in Dresden: in the German Empire (1871-1918), in the Weimar Republic(1919-1933) and in the German Democratic Republic(1949-1990). But we cannot find the image of teacher also. We can find the image of teacher at the toy museum rather than at the school museum. It is the miniature and only male teacher. There are few women teachers. We cannot find the teachers’ gatherings also at the school museum. I have visited to the school museum or toy museum in Holland, in England, in Germany, in Austria, in Switzerland, in Czech, in Korea and in Japan, but it is the same conditions. It is difficult to imagine the activity of teachers. I think that the reason is the reflection of historical and social conditions. But it is need to make students understand the historical background. Museums need to exhibit with various ideas.
