我校学生基础参差不一,悬殊很大。大面积提高初中化学教学质量,实现教学最优化,是化学教学中亟待解决的问题。下面,我根据多年的教学实践,以及对由省立项的课题《中学化学最优化教学研究与实践》的深入研究,谈谈自己在开展分层教学方面的做法。一、分析差异,把握层次,设计目标 The student base of our school is uneven, with great disparities. It is an urgent problem to be solved in chemistry teaching that improving the teaching quality of junior high school chemistry and realizing the optimization of teaching in a large area. Next, based on many years of teaching practice, as well as an in-depth study of the provincial project titled “High School Chemistry Optimization Teaching Research and Practice”, I talked about my own practice of conducting layered teaching. I. Analyze differences, grasp levels, and design goals
