Chinese students are good at mathematics but difficult to use
is another year's college entrance examination. In addition to each year's Chinese composition, another everlasting topic about the college entrance examination is the difficulty of the math test. After all, Chinese students have been famous for their good results in mathematics. The International Student Assessment Program (PISA), established by the organization for economic cooperation and development (OECD), carries out a quantitative analysis of the students' mathematical abilities every three years. According to the data of 2012, Chinese students are the first in the world, but on the one hand, their strong ability to learn mathematics can not effectively play a practical role and help solve the problems in life. The
OECD project group was randomly sampled in 65 countries (in China, using middle school students in Shanghai as a sample). The higher the students' learning ability and analytical ability, the higher the score was. Chinese students took a lead by 613 points, and even second Singapore (573 points) were 40 points worse. The average value of OECD countries is much worse than that, with only 494 points and a hundred points worse. However, when it comes to "problem-solving ability", the performance of Chinese students is not consistent with expectations. As shown in the longitudinal coordinates of the map, OECD has quantified the gap between the ability of solving problems and the results of mathematics, which is quantified as an indicator. Higher than 0 shows that the ability of students to solve problems exceeds their own mathematical level, and less than 0 shows that students are not very good at the knowledge of learning to use. China ranks on the top of the list in this index.
what is "problem solving ability"? OECD's report explains that in solving real life problems, excellent students can systematically recognize problems, design multistep solutions, take full consideration of various constraints, and adjust the whole plan in time by getting feedback. For example, when the meeting time is made, the time arrangement of the participants is conflicting. How to select the most appropriate time points is a typical "practical problem". OECD believes that, with the continuous grim employment situation and the need of economic development, excellent students must have the ability to solve the problems that often occur in life, so as to have more competitiveness and create more value.
in the whole coordinate axis shown in the figure, the position of Chinese students is in the lower right corner, which means that Chinese students have the best mathematical results and are the most difficult to use. However, due to the limited sampling conditions, the OECD report reflects only the situation of students in Shanghai. The quality education of the coastal open cities has been well done, and many provinces in the inland areas are more stringent on the students' mathematical performance, and the overall situation in the mainland of China may be worse than that in the imagination.
