The purpose of the present research is to analyze the content of the third grade Persian book based on the six fields of education. The research is of a descriptive type and was selected from the inductive method. The unit of page context (text, image) and the unit of recording the content of the text and image on the pages. For this purpose, after observing and studying the text and images of the Persian books of the third grade of elementary school in the period of four months, the desired contents were extracted. In the data analysis stage, extraction of the frequency of components related to moral education in the target textbooks was done using the researcher's content analysis checklist research tool, and to analyze the data obtained from the content analysis form, to examine the main research questions from Descriptive statistics indicators (frequency, percentage, graph and tables) have been used. The findings showed that among the six fields, the highest frequency was related to biological and physical fields by the amount of 132 cases and the lowest amount of attention was related to the scientific and technological fields by the amount of 2 cases. In total, Shannon's entropy estimate showed that the highest weight related to biological and physical fields and the lowest weight related to scientific and technological fields and economic and professional fields was 15 cases. It was also found that the amount of attention paid to the six fields is 0.32. Based on the findings, it can be said that by improving the level of attention of scientific and technological fields and economic and professional fields, it is possible to predict an optimal level of attention to the six fields in the third grade Persian textbook.
