针对传统的化学探究性教学中存在的一些问题,以“实验室中对氢氧化钠废水的处理”为例,将项目学习理念引入到教学中,提出了基于项目的化学探究性教学模式,并对该模式的流程进行了初步的探索。与此同时,结合教学实践,简单阐述了该模式相对于传统探究性教学模式的优势。在新课程理念的指导下,探究性教学模式取得了一些成就,比如有利于增加学生的学习兴趣,有利于学生解决问题的能力的培养,有利于学生自主完成知识的建构。同时不可避免地还存在一定的问题,比如对学生而言,对探究任务的全局不容易把握,在某种程度上不易激发学生的自主探究欲望,也不利于学 Aiming at some problems existing in the traditional chemistry inquiry teaching, taking “the treatment of sodium hydroxide wastewater in the laboratory” as an example, the concept of project learning was introduced into the teaching, and a project-based chemistry inquiry teaching mode , And made a preliminary exploration of the flow of this model. At the same time, combining the teaching practice, this article simply expounds the advantages of this model over the traditional inquiry teaching mode. Under the guidance of the new curriculum concept, exploratory teaching mode has achieved some achievements, such as helping to increase students ’interest in learning, developing students’ ability to solve problems and helping students complete the construction of knowledge independently. At the same time inevitably there are still some problems, such as students, the task of the inquiry is not easy to grasp the overall situation, to some extent not easy to stimulate students’ desire for independent inquiry, is not conducive to learning
