(一)突出重点、解决难点、新旧联系、讲练結合在課堂教学中如何調动学生的学习主动性?我觉得首先要做到突出重点,解决难点,新旧联系,讲练結合。例如,初中几何“三角形中位綫定理”一节,三角形中位綫的性质及其应用是个重点而用同一法证明“三角形的中位綫平行于所对的边”是个难点。 (A) highlighting key issues, solving difficulties, the old and the new links, the combination of teaching and training in the classroom how to mobilize the learning initiative of students? I think we must first highlight the key to solve the difficulties, old and new connections, training and integration. For example, the junior high school geometry “triangle bit line theorem” section, the nature of the bit line in the triangle and its application is a key point and the same method to prove that “the median line of the triangle parallel to the opposite side of the” is a difficult task.
