73-丽水高三数学（73- Lishui senior high school mathematics）

73-丽水高三数学（73- Lishui senior high school mathematics） Lishui senior high school the first mock exam questions analysis quality control The senior high school the first mock exam quality control test can do basic test of middle school mathematics basic knowledge, basic skills, basic ideas and methods of research, logical thinking ability, ability of ability and applying mathematics knowledge and methods to analyze the problem and solve the operation ability, space imagination. The average score is 76.24, some of the specific characteristics of the 25.85 variable difference test 33.91. standard deviation: adhere to the basic knowledge of the examination, at the intersection of design propositional knowledge network, pay attention to the application of mathematics in practice examination, Fill in the blanks on the test and analysis of quality score Fill in the blanks to highlight the ability of study students to use mathematical knowledge to solve the problem, the ability of the demand is higher, reflecting the change point of view, to test their ability. The overall difficulty coefficient is about 0.4. The science: 13 questions 0.35, 14 0.7, 15 0.2, 16 0.4. Typical error analysis The two main questions of science 13 wrong answer is 997, 0.023. The error is due to the content of this part is relatively unfamiliar, the relationship between the normal distribution and standard normal distribution is not clear; on the other hand is the lack of standard normal distribution and normal distribution to understand (a large number of students should be distributed in 100 minutes), resulting in the 977 error. The main problem lies in the lack of 0.023 read on the subject, otherwise how could appear 0.023 error? The 15 question of the wrong answer is 16. Obviously the error is a cycle or a half cycle selection. This shows that the students in the when there is a change in the independent variable between any two integers, the function f (x) at least deviation to a maximum value an
