在数学课堂教学中教师要充分了解学生已有的经验和水平,遵循从已知到未知、由表及里、由简到繁、由易到难的循序渐进原则创设情景。良好的情景创设更有利于学生自主、合作和探究学习方式的培养,从而更好地实施新课程。 In mathematics classroom teaching, teachers should fully understand the students’ existing experience and level, and follow the sequence from gradual and orderly progress from known to unknown, from form to form, from simple to complex, from easy to difficult. Good situation creation is more conducive to student autonomy, cooperation and inquiry learning mode of training, so as to better implement the new curriculum.
