Abstract Based on the difficulty evaluation model of “two dimensions and four indicators” established by Yan Chungeng, the current high school textbooks of China, Britain and the United States were selected as the research objects to evaluate and compare the difficulty of the “electrochemical cell” content. The study found that at the level of teaching material organization, the English textbook had the least difficulty, the Chinese version was more difficult; at the level of content representation, the Chinese version had the least difficulty, the English version was the most difficult. And this paper puts forward suggestions to strengthen multiple characterization, infiltrates the related concepts of “electric potential”, so as to provide reference for the compilation of China’s teaching materials and classroom teaching.
