In this essay I examine if socio cultural theory is present for teachers when pupils and students are using computers in class, especially when using blogs as a tool for learning. The aim of the essay is also to examine if blogs among pupils in class can promote peer support, co-operation and reflective dialogue, and in that case in what way. The essay consists of two studies, one small interview study and one literature study.  The interview study is made with the qualitative method phenomenographic analysis, presenting four Swedish teachers who have much experience using blogs in education. The aim of the literature study where some national and international research studies of relevance are presented, is to broaden the perspective.

The result of the interview study shows that a socio cultural theory is highly present among the teachers who already use blogs in education. In addition, those teachers experience that the blog in the classroom supports dialogue and co-operation among the pupils.  In contrast, the literature study shows that most teachers in Sweden who made their pupils work with computers in classroom seem to let their student work alone, without guiding them and without creating co-operation or dialogue in the classroom. Furthermore the literature study shows that there are many things teachers can do to improve their student to co-operate and reflect critically on a blog. One example is teachers in Taiwan who used themselves as role models by reflecting on their own teaching when blogging openly in front of their students. This encouraged their students to reflect critically concerning their own development.
