新课程改革实施以来,课堂教学发生了可喜的变化,但也带来了教学成本的攀高。笔者认为,课堂教学成本的选择应遵循量力性、节约性和高效性原则。作为一线教师必须树立科学的成本观念,践行高效的成本行为,丰富多样的教学资源,方能走出费时、费力、耗财、低效的成本误区,方能实现最优化的教育教学效果。 Since the implementation of the new curriculum reform, the classroom teaching has undergone a welcome change, but also brought about the rise of teaching costs. The author believes that the choice of classroom teaching costs should follow the principles of power, economy and efficiency. As front-line teachers must establish a scientific concept of cost, practice cost-effective behavior, enriching a variety of teaching resources, can get out of time, effort, loss of wealth, inefficient cost misunderstanding, in order to achieve the optimal education and teaching results.
