“创设生动有趣的学习情境”和“加强数学学习和学生生活的联系”是新课程实施过程中提出的两个重要理念。所以很长一段时间,教师们就把这两者结合起来,以现实情境创设作为数学课堂上重要的教学方式。然而在教学实践中,常常会出现盲目追求热闹,狭隘创设教学情境的现象:有的生活味浓了,数学味淡了;有的直观演示多了,数学思考少了……那种自认为是生活化、趣味化的情境创设,只是课堂的一种摆设和点缀,使教学陷入片面化、低效化的误区。 “Creating a Vivid and Interesting Learning Context” and “Enhancing the Connection between Mathematics Learning and Student Life” are two important concepts put forward in the implementation of the new curriculum. Therefore, for a long time, teachers have put these two together to create reality as an important teaching method in mathematics classroom. However, in the practice of teaching, there are often blind pursuit of lively, narrow creation of teaching situations: some lively flavor, math tasteless; some more intuitive presentation, less mathematical thinking ... ... that self-considered is Life, interesting situation creation, but the classroom a decoration and embellishment, so that teaching into one-sided, inefficient misunderstanding.
