This study was made in order to present the views of prospective secondary mathematics teachers about e-Geo, an electronic textbook developed by them. Thirty-six prospective teachers who have developed and evaluated their works were the participants of this qualitative inquiry. Data gathered were carefully analysed and thematised to determine perspectives related to the material. Findings gathered during and after the implementation of e-Geo activities show that they developed a positive evaluation appraisal. Prospective teachers remarked that they went by the mathematics curriculum and associated the activities with every day maths during e-Geo development process. (c) 2011 Published by Elsevier Ltd.
