The textbook as the main scientific resource guides the teacher and the student activities to achieve educational goals. Textbook content analysis enables the authors of the book to apply the results to improve the book. Chemistry is one of the most widely used fields which is very important in different fields. The purpose of the present study is to analyze the content of the first chapter of Chemistry Book grade 12, using William Romey's technique and determine the significance coefficient of each active, inactive and neutral categories by Shannon entropy method. The purpose of this study is applied and method is descriptive and of content analysis. To determine the validity of this study, the components of William Romey technique were used and Holsti formula was used to determine the reliability. The results showed that the engagement coefficient for the text of the first chapter was equal to 0.423 and was designed in the active way for William Romey but for images and questions it was obtained 2.083 and 16.4 respectively, which indicates inactive design. Also, based on the results of Shannon entropy method, the mean information load and the importance coefficient of the inactive categories were higher than the active one, while for images and queries it was the opposite.
