The Content Analysis the of Thermodynamics in the Second Edition Highschool Chemistry Textbooks Published in 1401 Using William Rumi's Method and Determining its Importance Based on Shannon's Entropy.

This research has investigated the extent of using the active method in the content of thermodynamics in second edition highschool chemistry textbooks volume 1, 2, 3. The purpose of this research is practical and clarify how successful the books has been in therm of active content. The statistical population includes 3 high school chemistry textbooks. First, the content of thermodynamics was identified and it was coded and analyzed using William Rumi's technique including text, images and questions in specific categories. The results of this research showed that the change of the coefficient of the categories (indicator of students' activity in the learning process) in the text, pictures and questions is 0.245, 1.33, and 5.30 respectively, so the text is less desirable than expected and passive, the images are desirable and active, and the questions are more inclusive and passive. Also, based on the results of Shannon's entropy method, the average information load and importance coefficient of passive text categories is higher than active, while it is the opposite in the field of images and questions.
