The use of technology in today's society is frequent and often necessary, but how, when and where are we supposed to learn how to use it? And if it is such a big and important part of our society, then why don’t teachers get more training in how to use the technology? The purpose of this paper is to examine whether teachers attitudes to technology affects their use of technology in their teaching. In school technology can be a complementary to other material, if teachers have the necessary skills to use technology in a pedagogical way. I have chosen to do a qualitative study in form of interviews and observations at a school outside of Stockholm. The results show that both school and teachers must want to work with technology if anyone will be getting something out of it. If schools invest a lot of money on technology that teachers can’t use, it is as bad as if the teachers would be in possession of all knowledge in the world but not be able to convey it. Schools must do more than just buy technology, they must give the classrooms enough computers so that several students can work at the same time, and they must have a functioning support and give the teachers necessary training in how to use it with their students. The teachers in this study said that there are several advantages and disadvantages of the use of technology in teaching. The advantages are that access to technology are fun for students and can often help them in different ways, the disadvantages are poor quality computers and the time it takes for the teachers to work with technology. During observations I could see that students who work together through technology enlisted help of each other, while students who work with books, completely forget the student who sits next to them and go directly to the teacher to get answers to their questions. Technology is here to stay and we must therefore adapt to it accordingly.
