情境自觉:小学情境数学的应然追求简

在小学情境数学课堂教学中，教师需厘清情境的内涵与外延，理解情境的特点和要义，通过对情境创设必要性的自觉考察，对情境创设合适性的自觉考虑，对情境简约性的自觉考量，对情境有效性的自觉考评，不断激发情境自我觉醒的源动力，合理利用引发自我反省时的摩擦力，着力提升情境自我创建的向心力，努力做到情境自觉。

Situational Awareness and Primary School Situational Mathematics

In primary school situational mathematics teaching, teachers need to untangle the connotation and denotation of situation, and understand its features and essential meanings. Teachers need to consciously examine the necessity of situational creation, consciously contemplate the suitability of situational creation, consciously weigh up the situational brevity, and consciously assess the effectiveness of situation, with a view to activating the dynamism of self-awareness, striving to diminish the friction of situational self-reflection, trying hard to enhance abilities of self-creation, and finally achieving the goal of situational awareness.
