2. Contact is objective, inherent in the thing itself and not dominated by human will. This requires us to grasp the internal relations of things and avoid being subjective and arbitrary. It is good to receive higher education, but you can't educate for the sake of education. Now some people cheat in order to get a higher education diploma, which has caused a decline in social credibility and caused adverse effects.
3. Things have a certain causal relationship, and every cause has its consequences. The popularization of higher education will inevitably lead to the decline of the quality of university education. The more popular things are, the more casual people are. Thus ignoring the quality of education. The loss of educational professionals and the advantages of selecting high-tech talents. Vulgarize social education.
4. The whole and the part are inseparable and influence each other. When the popularization of higher education affects the whole national education, it will lead to the decline of education quality. Therefore, it is necessary to improve the level of popular education, optimize the education system and improve it partially, so as to improve the quality of university education as a whole. Some parts should be subordinate to the whole. When the education system does not need to be popularized, we can appropriately choose whether education should be popularized or not, and don't let individuals affect the whole. We are required to look at the problem from a holistic point of view and learn to make overall plans.
I summed it up myself, and the answer was not good. I hope it helps.
