基于学生自主建构学科观念的课堂教学——以氨的教学为例

Teaching method based on students' concept of autonomous discipline construction——A case of teaching Ammonia

从建构化学学科观念入手,在问题化、情境化、活动化的"氨"的课堂教学中充分发挥学生的自主性,帮助学生建构元素观、微粒观、转化观、实验观等化学基本观念,追求化学教学的价值。

The present study suggests that based on the concept of constructing chemistry discipline,students initiative should be given full play in the class teaching of ＂ Ammonia＂ featured by questions,situations,and activities to help students construct the primary concept of chemistry such as view of element,molecule and transition in order to achieve the goal of chemistry teaching.
