《义务教育科学课程标准》中明确指出:小学科学课程实施探究式的科学教育,通过引导学生体验科学探究过程,初步形成对科学的认识,从而最有效地达到培养学生科学素质的目的。那么,如何高效地搞好探究式的实验教学,我认为最关键要创设实验情境,提高学生的探究兴趣。一个好的教学情境的创设,能激活学生的创新思维,激发起学生浓厚的学习兴趣,使学生在愉快的学习氛围中获 Compulsory Education Science Curriculum Standard clearly states that primary science curriculum carries out exploratory science education, and by guiding students to experience the process of scientific inquiry, initially forms the understanding of science so as to achieve the purpose of cultivating students’ scientific quality most effectively.
