The essay investigates how the e-reader changes the conditions for teaching in a development setting. By applying the theory designs for learning different aspects of the teaching practice are analyzed. Suzy Peacock Memorial Secondary School in Eldoret, Kenya was used for the collection of data. The results and the discussion show that while the teachers benefitted to a great extent from the e-readers while planning their work they did not use them to a great extent together with their students. Neither did the e-readers change how the teachers communicated knowledge nor their idea of what they wanted students to learn. In order for the e-readers to be implemented in the teaching and for the teachers to use the e-readers together with their students more, it is argued that teachers would benefit to a great extent from teacher training.
