In order to continuously deepen and consolidate the level of primary school students'autonomous learning ability,the study focuses on the research and analysis of the status quo of primary school students'mental kinetic energy and autonomous learning ability,and the influence of mental kinetic energy on primary school students'autonomous learning ability with questionnaire survey.The results of the data show that after the primary school students receive the intervention of learning mental kinetic energy,their learning mental kinetic energy and independent learning ability are at an above average level.There is high positive correlation between their learning mental kinetic energy and independent learning ability.At the same time,they realize that the scope of this research is relatively limited,and the scope of research should be expanded in the future.
