摘　　要：以化学实验为主的探究活动及学习体验,是化学学习的重要途径。以“实验室制取二氧化碳”为例,设计了“反应原理”“发生装置”“收集方法”“验满方法”等4个教学环节,对实验室制取气体的一般思路和方法进行建模。课上创设了3个学生活动,让学生尽情地动手动口动脑去体验,还创设了3个实验探究以解决3个认知冲突。学生在这样的课堂中生发感知、思维、情感、意志、价值观等多维的真实的内在体验,逐步形成化学学科观念、科学思维、质疑精神和创新意识,从而转变学习方式。Exploring activities and learning experiences mainly based on chemical experiments are important ways to learn chemistry.Taking"laboratory production of carbon dioxide"as an example,four teaching stages were designed,including"reaction principle""generation device""collection method",and"verification method",to model the general ideas and methods of laboratory gas production.In class,three student activities were created to allow them to fully engage in manual and mental experiences;Three experimental explorations were also created to address three cognitive conflicts.In such a classroom,students developed multidimensional and authentic inner experiences such as perception,thinking,emotion,will and values,gradually formed chemical ideas,scientific thinking,questioning spirit,and innovative consciousness,thereby transformed their learning methods.

关 键 词：实验探究活动 学习体验 二氧化碳 实验室制取
