新的化学课程标准指出,高中化学的学习是在初中学习的基础上更进一步地提高学生们的科学素养和探究能力,激发他们的学习兴趣,尊重他们个性发展的同时能够培养他们自主学习的能力,让他们能够更好地掌握化学知识.其中探究能力的高低,首先要有化学的质疑意识,这恰恰是现代学生所缺失的.学习起源于思考,思考起源于学习.在化学课堂上,我们应该善于设疑来激发学生的学习兴趣,同时帮助培养他们的探索精神和思维能力.教学过程是一个特殊的认知过程,也是一个 The new chemistry curriculum standard points out that senior high school chemistry learning is based on junior high school learning to further improve students’ scientific literacy and inquiry skills, stimulate their interest in learning, respect their personality development, and develop their self-learning ability , So that they can better grasp the chemical knowledge, which explore the level of ability, first of all have the chemical sense of doubt, which is precisely the lack of modern students.Studies originated in thinking, thinking originated in learning.In the chemistry class, we Should be good at setting suspicions to stimulate students interest in learning, and help develop their exploration and thinking skills. Teaching process is a special cognitive process, but also a
