"Learning before teaching"has become a popular educational concept in recent years.The idea of"learning first"has long existed,and with the support of concepts like"student-centered"and"people-oriented","learning first"has been elevated to a position equal to or even higher than"teaching".However,the self-learning abilities of primary and secondary school students are limited.Emphasizing"learning"while neglecting teacher guidance makes the effectiveness of"learning first"questionable.Additionally,"teaching"must occur simultaneously with"learning";there is no such thing as"teaching later"in isolation.Many aspects of"teaching"do not require"learning first"as a prerequisite.Teaching and learning should be unified activities,which is particularly challenging for foundational and skill-based knowledge instruction.To achieve this unity,teachers need to artistically guide students'thinking,helping them escape the pitfalls of rote memorization and mechanical problem-solving,thereby promoting learning through teaching.
