Abstract
 
Introduction: Considering the role of science education in the economic growth of every country, it is included in the curriculum of k12 education. In the meantime, green chemistry has been given attention in science education. Green chemistry is one of the most fundamental approaches used in sustainable development. Textbooks are expected to pave the way for sustainable development by educating the principles of green chemistry. The goal of green chemistry is to design products and processes that are compatible with the environment and minimize the risks caused by chemicals.
Objective: The application of the principles of green chemistry in the subject of electrochemistry in the chemistry textbook was investigated in this research.
Method: This research is descriptive-analytical and it uses the method of content Analysis. The statistical population of the study is the 3rd grade chemistry textbook and the studied sample is the second chapter of this book in terms of attention to electrochemical concepts, which includes pictures and text containing titles, written sentences, and questions. The research tool was the twelve principles of green chemistry. The research method was based on the census of the analysis units based on the aforementioned principles. To achieve content validity, the opinions of experts in chemistry education were considered and the results were presented in the form of descriptive statistics.
Findings: Findings from content analysis showed that about 31% of the content has an educational approach based on green chemistry, which refers to 9 principles of green chemistry. On the other hand, principles 8, 10, and 11 principles of green chemistry have not been considered. Also, due to the role of electrochemical knowledge in providing clean energy, the principle of maximum energy efficiency had the highest percentage of frequency in the designed content based on attention to the environment.
