Due to the development of industry and commerce and the needs of urban life, the developing emerging bourgeoisie demands the establishment of a middle school that pays attention to imparting practical knowledge. From 65438 to 0708, Schiller, Vice Bishop of Haller College, founded the Middle School of Mathematics, Mechanics and Economics. The school teaches mathematics, physics, mechanics, nature, astronomy, geography, law, drawing and drawing, and widely uses visual AIDS such as painting, scientific charts, specimens and models in teaching methods. This is a new middle school with both general education and vocational education. Under the influence of this school, many towns have set up similar schools.
