夸美纽斯说过:“只要有合适的教育,就一定能节省教与学的时间与精力。”化学课堂中教与学的优化,能激发学生的学习兴趣,培养学生的学习能力,提高学生的合作意识,提升课堂教学的效益。把教法、学法放到具体的课堂教学实际中看,前者应服务于后者,教是手段,学才是目的。为了更好地提高化学课堂的学习效益,我从优化教师的“教”、优化学生的“学”、优化评价方式三个方面进行实践和探索。 Comenius said: “As long as there is a proper education, we can save the time and energy of teaching and learning. ” The optimization of teaching and learning in chemistry class can stimulate students ’interest in learning and develop students’ learning ability , Enhance students’ awareness of cooperation and enhance the effectiveness of classroom teaching. The teaching method, learning law into the actual teaching of the classroom, the former should serve the latter, teaching is a means of learning is the purpose. In order to improve the learning efficiency of chemistry class better, I practice and explore three aspects: optimizing teachers ’teaching, optimizing students’ learning and optimizing evaluation methods.
