Based on observations to some high schools, found that there are no schools used the computer as mind tools in mathematics. This study aimed to develop an integrated ICT textbook that can be used by teachers and students to improve the effectiveness of learning mathematics. To facilitate teachers and students in using the computer program, the book comes with a CD tutorial. CD Tutorial consists of a guide to using multiple software and examples of applied learning senior high school mathematics grade X first semesters. Design research method was adopted in this study. The textbook developed with Plomp model and referred to Tessmer formative evaluation. Self-evaluation and validation sheet are used as an instrument. The findings show that the textbook is valid, practice, and effective from the content and construct aspects. Test results of post-test have increased enough significant impact on a pre-test. The effectiveness of using the textbook is seen by a normalized gain calculation, obtained a normalized gain value of 0.68. It means the textbook developed effectively in improving learning outcomes students.
