化学用语,溶液的计算,无机物的相互关系。是初中化学教学中的三个分化点,处理不好,使学生的学习积极性受到挫折,兴趣降低,乃至发生厌恶。下面谈谈我们是怎样突破这三个分化点,保持学生学习兴趣的做法。一、造成分化的原因(1)从教师方面来说,往往不按大纲要求教学,如溶解度的计算,认为高中不再学习,要以高考要求进行加深拓宽,计算类型搞得很全。再如无机物相互关系这部分教材,是
Chemical terms, calculation of solutions, and interrelationship of inorganic substances. It is the three differentiating points in chemistry teaching in junior middle school. It is not handled well, and the students’ enthusiasm for learning is frustrated, their interest is reduced, and even their disgust occurs. Let’s talk about how we broke through these three differentiation points and keep students interested in learning. First, the causes of differentiation (1) from the teacher’s point of view, often do not follow the outline requirements of teaching, such as the solubility calculation, that the high school no longer learn, to deepen the college entrance examination requirements to widen, the type of calculation is very complete. Another example is the teaching of inorganic materials.
