摘　　要：针对当前化学概念教学中“教师传授-学生接受-强化训练”这一模式难以适应“素养为本”教学的现状,提出以“深度学习”指引化学概念教学。以“化学史”为背景,以“认知冲突”为手段,以情境、数据和问题等各种支架为支撑,以定性与定量相结合的方式引导学生从熵的引入、熵的深化、熵的拓展、熵的应用等4个方面完整地构建熵这个新概念。In view of the fact that the mode of"teacher teaching-student receiving-intensive training"in the current chemistry concept teaching is difficult to adapt to the"literacy-based"teaching,"deep learn-ing"is proposed to guide the chemistry concept teaching.With the background of"the history of chemis-try",the means of"cognitive conflict",and the support of various scaffolds such as situations,data and problems,the students are guided by a combination of qualitative and quantitative methods to completely construct the new concept of entropy from four aspects:the introduction of entropy,the deepening of entro-py,the expansion of entropy and the application of entropy.

关 键 词：深度学习 概念教学 熵 熵变
