在新课程标准的实施过程中,情境教学法成为被广大教师所采纳的基本方法,但是由于教师理解偏差和能力不同,情景设置存在很多问题。教师应该遵循科学适度的原则,根据所学内容的性质与地位设置情境,以更好地揭示数学的本质。 In the process of implementing the new curriculum standards, situational teaching has become the basic method adopted by the majority of teachers, but there are many problems in setting scenarios due to teachers’ different understanding of deviations and abilities. Teachers should follow the principle of appropriate science and set the context according to the nature and position of the content they learn to better reveal the essence of mathematics.
