化学是一门以实验为基础的科学,化学实验则是化学学科发展的重要基础。虽然在实验目的、研究对象、实验条件等方面,中学化学教学中的实验与科学研究中的实验有所不同,但在认识过程中二者的本质是相同的。因此,实验成为中学化学教学内容的重要组成部分,是化学教师常用的教学方法,也是学生学习的有效学习方式。能否充分发挥化学实验在中学教学中的作用,在很大程度上决定着化学教学质量的高低。一、开展探究性实验教学的意义1.培养学生学习化学的浓厚兴趣,调动学生的学习积极性。学生会在好奇心的驱使下,对未知结果的探究实验产生极大的兴趣,从而产生强烈的学习欲望和学习的积极性,学生的潜能也会在
Chemistry is an experiment-based science, chemical experiment is an important foundation for the development of chemistry. Although experiments in middle school chemistry teaching are different from those in scientific research in terms of experimental purposes, research objects and experimental conditions, the essence of the two is the same in the process of cognition. Therefore, the experiment has become an important part of the content of chemistry teaching in middle school. It is a common teaching method used by chemistry teachers and also an effective way of learning for students. The role of chemistry experiment in middle school teaching can be brought into full play, to a large extent, it determines the level of chemistry teaching. First, to explore the significance of experimental teaching 1. Cultivate a strong interest in learning chemistry, arouse students’ enthusiasm for learning. Driven by curiosity, students are greatly interested in exploring experiments of unknown results, resulting in a strong desire for learning and enthusiasm for learning. The potential of students is also
