化学学科由于学生到初三才开始接触,而且里面都是元素符号、化学式、结构式与化学反应方程式等很抽象的知识,所以学生学起来不感兴趣,产生了一部分化学学习的学困生,影响了这些学生的学业发展和能力的提高,因此,教师要想法设法的利用化学学科的特点在化学教学中激发学困生的学习热情。 As the chemistry began to come into contact with the third day of the third year, and there was abstract knowledge of elemental symbols, chemical formulas, structural formulas and chemical reaction equations, the students were not interested in learning and produced part of the learning-impoverished students that affected these Students' academic development and ability to improve, therefore, teachers should try to use the characteristics of chemistry to stimulate learning passion in chemistry teaching students.
