化学是一门以实验为基础的学科,然而在旧的教学模式下,演示实验、学生实验多为验证知识和现象的实验,没有充分发挥实验的作用。随着教学改革的不断深化,研究性学习已步入课堂,而化学实验教学以它的实验性和实践性,蕴藏着丰富的素材,是学生进行研究性学习的很好载体。研究性学习 Chemistry is an experiment-based discipline. However, under the old teaching model, demonstration experiments and student experiments were mostly experiments to verify knowledge and phenomena, and they did not fully exert the effects of experiments. With the continuous deepening of teaching reforms, research-based learning has entered the classroom. The experimental teaching of chemistry, with its experimental and practical nature, contains abundant material and is a good carrier for students to carry out research-based learning.
