In the teaching process, exercise practice constitutes the most critical component. However, the difficulty of exercises varies significantly. To enable teachers to assign homework of appropriate difficulty levels, establishing a scientific difficulty evaluation system is particularly essential. We employs an AI-based difficulty evaluation equation specifically designed for exercises on the First Law of Thermodynamics to classify their difficulty levels. Through testing on the Superstar Learning Platform with two cohorts of students, the difficulty coefficient is calibrated by integrating a correction term ε and student test results, ultimately establishing a scientific and efficient exercise difficulty evaluation system.

Marx's ecological thought represents a significant theoretical achievement in his exploration of the relationship between humans and nature. From the perspective of its intellectual context and development path, Marx interpreted the human-nature relationship by grounding it in concrete human productive activities, thereby completing an interpretation of the tripartite unity of humanity, nature, and society within the framework of historical materialism. Theoretical, practical, and value dimensions constitute the three primary approaches through which Marx elucidated the human-nature relationship. This ideology provides crucial theoretical guidance for ecological civilization construction in the new era and charts a path toward harmonizing human-nature relations.
