Evaluation of mathematics learning content. For example, if the first year students did the wrong question on the set, is it because they don’t understand the concept of the set, or are they not able to do the questions about inequalities in the set? There is a difference. If the concept of set is not possible, just make up for this knowledge; the inequality errors in the solution need to be further subdivided, and the final result may be that the factorization is not possible. This requires knowledge from junior high school to help him improve.
The knowledge of middle school mathematics is a spiral system. Any knowledge is related. If the foundation is not strong, the building above will collapse.
Evaluation and diagnosis is to find out what students really don’t understand, so as to make up for it effectively.
: In the process of understanding student learning problems, did you encounter any difficulties?
Tian Peiqing: Completing the mathematics ability assessment system is a difficult task. Four Seasons Education invests a lot of manpower, material resources and financial resources. After repeated discussions within the team, after countless affirmations and denials, it is because it always feels that it is not scientific enough, and it is worried that such an evaluation system will not work well after it is introduced to the market. This is not education work. Should do.
In April 2018, we signed a strategic cooperation agreement with the Department of Mathematics of East China Normal University, mainly to build an intelligent mathematics laboratory and improve the mathematics ability evaluation system.
I believe that as long as there is a breakthrough in the evaluation system, the qualitative change from 0 to 1 can be completed. We have been in research and development for seven years, and we have cooperated with China Normal University for more than two years. We have initially reached our goal and will be launched this year. At that time, the scientific evaluation and diagnosis report of this AI system will play a vital role in the effective learning of students.
: There are already many question banks on the market. How does Four Seasons Education ensure differentiation?
Tian Peiqing: What is the essence of education? Is wake up. The main task of the student stage is to develop a good way of thinking and study habits, and be able to learn effectively. What is effective learning is to understand and learn more in unit time. In other words, a certain knowledge point can be understood in the least time, teaching emphasizes thinking methods, and the topics are only concrete practical cases, and the examination-oriented education is only a way of completing the topics.
Take mathematics as an example, all knowledge points from elementary school to high school are limited, systematic, and coherent, and can be sorted out clearly by using knowledge maps. There are syllabuses for middle school and college entrance examinations. If there is a standard core question bank, many problems can be solved.
About the question bank, I don’t think the more questions you collect, the better. Students are limited in doing questions, not because they are too many but not because they are focused. The purpose is to digest, understand and draw inferences from one another. We believe that the question bank of the question bank should first be established as the core question, and it is the core question that has been identified. It is expanded on the basis of the core question. Our question bank is based on this gene.
