针对成人的特点进行教学方法研究和改革是我们成人教育工作者的一个重要任务。因为在各类成人学校中,从生源来看,年龄普遍偏大,文化课的基础知识差,程度参差不齐。从授课情况来看,周期较短,学时过于集中。从教材来看,深度较大,尤其是大专专修班教材多数使用的是普通高校教材。这些特殊性,给各科教学带来了很大困难,尤其是理科教学困难更大,因此要提高成人教育的教 It is an important task for our adult educators to carry out teaching method research and reform in response to the characteristics of adults. Because in adult schools of all kinds, from the perspective of students, the age is generally too large, and the basic knowledge of cultural classes is poor and uneven. From the teaching situation, the cycle is short and the hours are too concentrated. From the point of view of teaching materials, the depth is relatively large, especially the textbooks for college specialized courses used mostly for teaching materials in ordinary colleges and universities. These particularities have brought great difficulties to the teaching of various subjects, especially the difficulty in teaching science, so we must improve the teaching of adult education.
