新课标改革已经将近十年，新课标理念在教学实践中的实施，离不开教学情境的创设，可以说，情境创设是教学实施成败的关键，而教学实施又是课改成败的关键。然而我国基础教育长期以来受应试教育的影响和现在高考制度的“高考压力”影响,不少教师特别是老教师，仍然采取传统的教学方式，而另一部分教师虽然重视情境教学，但对情境教学的理解不是很明确或缺乏相应的时间、精力、能力，找不到或创设不出适宜、确切、有效的情境，使情境教学形同虚设或有境无情。在课堂教学中，创设适宜的情境，能激起学生的兴趣，激发学生的求知欲，促使学生自主学习、积极思考、乐于探究，培养学生的科学素养，促进学生的思维能力和情感发展，不但实现了学生学习方式的改变，提高了教学效率，还全面提高学生的素质，真正体现新课标理念和实践素质教育。本文阐述了开展情境教学的历史背景，新课程理念下情境教学的必要性和开展情境创设研究的意义。通过对情境教学等概念的论述得出教学情境的特点，分析情境教学研究的发展状况，介绍情境教学的理论基础：建构主义学习理论、情境认知与学习理论、心理学角度、新课标角度。通过文献和我校课堂教学实例分析中学化学教学情境创设存在的问题，探讨情境教学的功能、情境创设的原则、情境素材的搜集、情境创设的方法，最后以具体的案例说明情境创设要注意的问题。
