Investigating the amount of attention paid to environmental components in the science textbooks of the first secondary school based on Shannon's entropy method
Today, one of the environmental problems facing the development of technology in the world is environmental pollution. And without a doubt, the science textbooks of the first high school course are one of the official platforms for environmental education. The current research was conducted with the aim of examining the content of science books of the first high school course, in terms of attention to environmental components.
This research is of applied type. In which, the science textbooks of the seventh, eighth and ninth grades of the academic year 1399-1400 have been examined. which totals 45 chapters and 450 pages. The examined samples include texts, images, questions and book activities that have been studied using Shannon's entropy method. This study was carried out using a content analysis checklist tool that has four environmental components: water, air, soil and sound, in 1400, and its content validity was confirmed by subject experts and its reliability coefficient was 91/36. The percentage is estimated.
Fidings:
The results of the research indicate that environmental components have been given little attention in science books of the first secondary school. The most attention is in the book of sciences of the seventh grade and the least attention is related to the book of sciences of the eighth grade.
In these books, in the field of the four environmental components, the most attention has been paid to the air component and the least attention to the sound component. Also, the highest coefficient of importance was related to the soil component with (Wj=0.308) and the lowest coefficient of the sound component (Wj=0.199). Among the different sections of science books, the highest coefficient of importance is related to biology chapters (Wj=0.329), followed by chemistry and physics chapters, and the most important coefficient is related to geology chapters. (Wj=0.176) is less than the others.
