我们都知道用实物教学,效果是良好的。因此,教物理化学等课程,就必须有充足的仪器和教具及时地进行演示。我人民政府成立以来,大力发展教育,建立了很多的学校,如果想在很短的期间把各学校的一切仪器都置备齐全,是有些困难的,只要我们教师肯开动脑筋发挥创造力自制仪器,这些困难是能克服的。 We all know that using physical teaching, the effect is good. Therefore, to teach courses in physics and chemistry, we must have adequate equipment and aids in a timely manner to demonstrate. Since the establishment of the People’s Government of our country, we have made great efforts to develop education and established a large number of schools. If we want to complete all the facilities in schools in a very short period of time, it is somewhat difficult. As long as our teachers are willing to use their brains to create their own homemade instruments, These difficulties can be overcome.
