The purpose of this research is analyzing the content of the tenth grade chemistry textbook based on William Romi’s categories. The research method is descriptive and content analysis using Shannon entropy method. The statistical population of the book is 1398. A total of 54 pages were randomly selected from chapters for analysis of text, images and questions. In this study, the frequency of active, inactive and neutral categories was calculated based on William Romi’s model and then normalized based on Shannon entropy method. The results show that in passive text analysis the passive category has the highest coefficient of significance (0.142) and the neutral category has the least coefficient of significance (0.070). In the image analysis, the inactive and active categories were almost as important as the percentage factor, and only the inactive category was two percent higher than the active category. In the analysis of questions as opposed to the images and text of the book, the importance factor of the active category (0.280) was higher than that of the inactive category (0.22), and this analysis showed that in the content preparation the balance between the text, images, and non-observed questions and the text of the book was inactive.
