初中化学是化学课程的起始阶段,有大量的基础知识需要学习和记忆,如化学式、物质的物理性质和化学性质等。而初中化学到九年级才开,学生正面临着升学,学习压力非常大,优化教与学的方法、转变教学方式、减轻学生负担、提高学习效率是教师进行授课时的核心目标。笔者经过实践发现,微课程灵活多样、短小精悍,能极大激发学生兴趣,提高学生的学习效率。 Junior high school chemistry is the beginning of the chemical curriculum, there is a lot of basic knowledge you need to learn and memory, such as chemical formula, the physical and chemical properties of matter. The middle school chemistry to the ninth grade to open, the students are facing further studies, the pressure of learning is very large, optimizing teaching and learning methods, changing teaching methods, reduce student burden, improve learning efficiency is the core goal of teaching teachers. After practice, I found that micro-curriculum flexible and short, diligent and can greatly stimulate student interest and improve student learning efficiency.
