(1) layers alternate. From junior year to senior year, from primary school to middle school to university to graduation, there are opportunities, subjective conditions and competitiveness, and successors are produced through artificial selection.
(2) Knowledge transmission. It is a spiral and wave-like development model.
(3) Periodic succession. With the development and progress of social economy, the material and energy input to education is increasing year by year, which usually shows periodic succession year by year, and it is also 6.5 in China; 7.5; 8.5 Succession with a 5-year cycle as planned.
(4) Secondary succession. Continuing education and adult education belong to secondary inheritance.
(5) The interruption and jumping of succession. Repetition and dropping out of school belong to succession interruption, and skipping classes belongs to succession jump. There are objective factors as well as subjective factors. Generally speaking, the latter is more important.
(6) Retrograde succession. For example, the neglect of studies has become illiterate and semi-illiterate.
(7) The evolution trend of vertical education structure. If the proportion of people with different education levels is different under different per capita income levels, this vertical evolution trend can usually be analyzed by regression analysis.
The evolution of ecosystem has its internal and external manifestations, and its fundamental driving force comes from within the system. Through the interaction between subsystems and the mutual adjustment of environmental changes, the negative entropy factor is constantly increased in the orderly whole of the ecosystem, so as to achieve the purpose of adapting the system to the environment, and so is the educational ecosystem, but people can often adjust their development goals-through decision-making. Correct decision-making can promote the evolution of the system, otherwise, mistakes in decision-making will lead to defects and disorder of the system. But on the whole, due to the accumulation of material and energy knowledge and information, the succession and evolution of the system is irreversible, but it is constantly advancing.
At present, with the deepening of China's economic, political and scientific and technological system reform, all levels and systems within the educational structure are impacted by external forces. The foundation of education needs to be reformed, the educational system needs to be reformed, the content of education needs to be updated, and the concept of education needs to be profoundly changed. How to combine the means and methods of educational ecology with various educational theories to study these factors more deeply and systematically. The interaction between them and their effects on the education system have supplemented and formed a more scientific theoretical basis for the development of education in China, which naturally becomes the central task of the study of educational ecology in China. The above briefly introduces the basic outline of this new discipline-educational ecology. I hope we can work hard for this discipline to become one of the world's scientific forests as soon as possible!
