In Iran's centralized education system, the content of textbooks plays a pivotal role in achieving educational goals because it reflects key ideas,basic concepts, principles, and laws of each scientific discipline and has a direct impact on the learning process and academic achievement of students. The present study is an applied study in terms of purpose and a historical study in terms of method. Shannon entropy method was used to process data and validate findings. The research population consists of Iranian elementary science textbooks from 1350 to 1400.Given the relative stability of the content, books from 1354, 1378, and 1395 were selected as samples.In this study,key ideas and basic concepts of various branches of experimental sciences including chemistry, physics, biology, geology, and health were extracted from the selected books, counted, and their frequency percentages were calculated,and then comparative graphs were drawn. Subsequently, the information load and importance coefficient of each branch were determined using Shannon entropy.The findings showed that the chemistry branch,compared to other branches of experimental sciences, has the lowest frequency of key ideas and basic concepts in the time periods studied; however, the results of Shannon entropy indicate that chemistry is of the highest importance. Also, a direct and consistent relationship was observed between the concepts of chemistry and other branches of experimental sciences. Accordingly, it is suggested that in future revisions of the elementary science curriculum, while maintaining an integrated approach, more attention should be paid to strengthening and distributing chemistry concepts in proportion to their high importance.
