摘　　要：在“探究浓度对化学反应速率影响”化学学习任务的教学实施过程中,引导学生寻找解决问题的突破口,设计并实施探究实验,形成认知。呈现资料卡片,引发学生认知冲突,产生质疑;师生协作,重新寻找解决问题的突破口,进一步发展学生对“浓度对化学反应速率影响”的认识水平。在教学实践中激发学生的质疑精神,塑造学生的必备品格,提升学生的关键能力。During the teaching implementation of the chemical learning task of“exploring the influence of concentration on chemical reaction rate”,students are guided to find a breakthrough to solve problems,design and implement exploratory experiments,and form cognition.Teachers present data cards,triggering students’cognitive conflict and questioning;teachers and students work together to find a breakthrough to solve the problem and further develop students’understanding of the impact of concentration on chemical reaction rate.In the teaching practice,we should stimulate students’questioning spirit,mold students’necessary character and improve students’key ability.

关 键 词：化学学习任务 关键能力 探究实验 化学反应速率 浓度
