长期以来,不少教师重解题、轻定义,对定义的要求往往只满足于单纯的记忆,使学生对椭圆定义的本质不能深刻理解和运用,造成数学定义与解题脱节的现象,解题时常感到束
For a long time, many teachers have solved the problem and defined lightly, and the requirements of definition are often only satisfied with mere memory. Students can not profoundly understand and use the definition of ellipse, resulting in the phenomenon of mathematical definition and solution, Always feel the beam

教学是教与学的统一, 这种统一的实质是交流。教学是一种对话、一种沟通, 是合作、共建, 是以教促学、互学互教的过程。但由于种种原因,许多教师教学观念相对陈旧、模糊, 缺乏对新理论的学习和自我反思。一些教师在理论上虽有所认识, 但在实践操作中却不得要领。因此, 提高课堂教学实效性迫在眉睫。而提高课堂教学效益的关键就在于优化课堂教学结构, 培养学生学习兴趣, 让学生乐于学, 让学生学会学。结合新课程培
