The electrochemical principles course is a commonly offered course in disciplines such as chemistry, chemical engineering, materials science, environmental engineering, and renewable energy. The commonly used textbooks for this course are often written based on "disciplinary thinking," which does not align with students' cognitive laws. Based on the "cognitive laws," the author has reconstructed the chapter on electron transfer step kinetics in the electrochemical principles course. This reconstruction will contribute to the achievement of students' objectives and reflect the thinking and connotation of the construction of new engineering disciplines.
