在高考这个指挥棒的催逼下,高中数学学科仍然停留在海量解题训练的怪圈中,高密度、大容量的训练题,使得更多的学生负重前行,而相对紧张的课时训练,又增强了学生的逆反心理,学习兴趣与日俱下。过分注重对学科知识的训练与掌握,教师缺乏必要的科学态度和丰富的教学方法,忽视了在知识学习过程的对学生主动性的激发。为此,抓住课堂教学的有力阵地,通过师生互动教学来营造高效课堂,需要树立科学的教学策略,才能更好地取得事半功倍的教学效果。一、备课是改进课堂教学的有效前提备课是教师开展高效课堂教学的前提,通过对例题、 Under the urging of the college entrance examination baton, high school mathematics subjects still remain in the vicious circle of mass problem solving training. The high density and large-capacity training questions lead more students to take the weight forward while the relatively tense class time training increases Students of the rebellious, interest in learning day by day.
