“以学生为本”是新课程改革的基本思想,探究性学习是新课程实施的一个热点,自主学习是一种让学生主动参与学习的学习方式。化学学科的特点是开展化学实验的探究,让学生“模拟”科学家去探索问题,学习科学研究的方法,养成良好的思维品质,培养学生的观察、思维、操作、想象能力,使学生积极主动去获取知识,激发兴趣,培养创新精神和实践能力。一、创设情境,激发学生的探究欲望学生在学习活动中,对自己感兴趣的事物总是表现出积极的态度,“知之者不如好之者,好之者不如乐之者。”因此,教学中可以把学生熟悉的生活环境设计成实验小故事、实物图片等,用于创设 “Student-oriented ” is the basic idea of ​​the new curriculum reform. Inquiry-based learning is a hot spot in the implementation of the new curriculum. Autonomous learning is a kind of learning method that enables students to actively participate in learning. Chemistry is characterized by chemical experiments to explore, so that students “simulation ” scientists to explore the problem, learn the scientific research methods, develop good thinking quality, develop students’ observation, thinking, operation, imagination, so that students Take the initiative to obtain knowledge, stimulate interest, develop innovative spirit and practical ability. First, the creation of situations to stimulate students’ desire for inquiry Students in the learning activities, always interested in their own things to show a positive attitude, “the better than those who know, the better is not as good as the music. ” Therefore , Teaching students can be familiar with the living environment designed to experimental stories, pictures, etc., used to create
