1, strict examination evaluation system, make the score as fair as possible.
If the error between the arbitration score and the marking score is too large, it will be recorded as "bad review" as an important basis for calculating the workload of the marking teacher. Those with high bad review rate will be dismissed, and the dismissal report will be fed back to the education bureau and school where the marking teacher is located, and will not be hired in the future college entrance examination marking.
2. Scoring rules are the concrete embodiment of marking standardization.
Compared with the usual marking by teachers, the scoring rules of the college entrance examination emphasize the grasp of knowledge points more objectively, and the scoring is based on the principle of "giving one point is reasonable and deducting one point is reasonable". ? Find the scoring point, and score by "seeing is scoring" and "stepping on the spot", and there is no connection between up and down.
3. Electronic marking requires high speed, which puts higher demands on marking teachers.
I read up to 6,800 books a day, with an average of 970 books per hour. The average time to read a big topic is only 3.7 seconds, almost reaching the degree of mechanical conditioning.
Most of the math problems in the college entrance examination are 2-3. Most marking teachers are used to displaying a big question on the whole screen without turning pages. The images and characters in the electronic volume are too small, the handwriting is unclear, the writing is not neat, and the typesetting is unreasonable, which will make it difficult for the marking teacher to identify them, and it is very likely that the candidates will miss the marking points and lose points.
Matters needing attention in college entrance examination mathematics:
1. Read and understand correctly, and find out the meaning of the question: the application questions related to probability and statistics are often based on real life and often tested with new ideas. The key to solving the problem is to understand the meaning of the problem, find out the essence, and turn the actual problem into a mathematical problem.
2. For mutually exclusive events, what we should grasp is that it can't happen at the same time, but for the opposite events, except that they can't happen at the same time, their combined events should be inevitable events, which can also be understood through analogy set. In the specific application, we can write all the test results and see which test results are included in the requested events, so as to judge the relationship between the given events.
3. When using the histogram of frequency distribution to solve related problems, we should correctly understand the meaning of each quantity in the chart. Knowing the graph and grasping the information are the keys to solve such problems.
4. Changes in some data may have no effect on the median. The median may or may not appear in the given data. When the individual data in a group of data changes greatly, the median can be used to describe its centralized trend. Mean and variance are both important numerical characteristics, which are concise descriptions of the population, and the situation they reflect has important practical significance. Mean, median and mode describe their concentration trend, while variance and standard deviation describe their fluctuation.
