近几年,加强数学应用教学,培养学生应用数学的意识,已成为数学教育工作者的共识.上海市二期课改数学新教材强化了应用问题的教学,例如,在“三角函数的性质与图像”一章中,设计了“漏斗的摆动”、“心电图周期”、“摩天轮座舱高度”、“海水的涨潮和落潮”、“电流强度随时间变
In recent years, strengthening mathematics application teaching and cultivating students’ awareness of applied mathematics has become the consensus of math education workers.Shanghai’s new mathematics teaching materials of secondary curriculum reform strengthen the teaching of application problems. For example, in “the nature of trigonometric functions and Image ”chapter, the design of the“ funnel swing ”,“ ECG cycle ”,“ Ferris wheel cockpit height ”,“ sea water tide and ebb tide ”," current intensity changes with time
