化学是一门以实验为基础的自然科学,化学实验对全面提高学生的科学素养有着极为重要的作用。化学实验教学的有效性是指:通过化学实验教学后学生在知识与技能、过程与方法、情感态度与价值观(即三维目标)获得了进步或发展。因此,提高化学实验教学的有效性显得尤为重要,也成为广大一线教师关注的重点。经过多年教学实践,笔者在化学实验教学的有效性方面有了一些想法,愿与各位同行商榷。
Chemistry is an experiment-based natural science. Chemistry experiments play an extremely important role in improving students’ scientific literacy. The effectiveness of chemical experiment teaching means that students gain progress or development in knowledge and skills, processes and methods, emotional attitudes and values (ie, three-dimensional goals) through chemistry experiment teaching. Therefore, it is very important to improve the effectiveness of chemistry experiment teaching, which has also become the focus of teachers in the field. After years of teaching practice, the author has some ideas on the effectiveness of chemical experiment teaching and is willing to discuss with you.
