探究性学习是指学生在教师指导下,自主获取知识和技能,体验和了解科学探究的过程和方法。在化学教学中,教师要为学生的学习创设探究情境,建立探究的氛围,把握探究的深度,激发学生的探究欲望,引导学生体验探究的过程,自己发现问题、提出问题、分析问题、解决问题。教师选择的探究主题,要有一定的可探究性和可操作性,有计划、有步骤地培养学生的科学探究能力,促使他们自己去获取知识、发展能力。在化学教学中可从以下几个方面实施探究性学习。

Inquiry learning is the process and method by which students acquire knowledge and skills autonomously under the guidance of teachers and experience and understand scientific inquiry. In chemistry teaching, teachers should set up inquiry situations for students, establish the atmosphere of inquiry, grasp the depth of inquiry, stimulate students’ inquiry desire, guide students to explore the process of inquiry, find problems by themselves, ask questions, analyze problems and solve problems . The theme of inquiry chosen by teachers should be researchable and operable. Students should be trained in scientific inquiry systematically and step by step so that they can acquire knowledge and develop their own ability. In chemistry teaching can be implemented from the following aspects of inquiry learning.
