Analysis of the final examination paper of fourth grade mathematics in primary school published by People's Education Press
I. Scope and characteristics of the proposal
This mid-term exam is a unified proposition of the school district. The test questions cover the knowledge points of the first, second, third and fourth units of mathematics in grade four, and the four topics are * * *. It is divided into four aspects: concept understanding, computing ability, drawing operation and practical application. The examination questions attach importance to the examination of basic knowledge, basic skills and problem-solving ability. It embodies the rationality of the new curriculum standard of mathematics. Generally speaking, the test questions are moderately difficult and reasonably designed, which are suitable for middle and senior students to answer.
Second, the overall situation
In the fourth grade, 29 people took the exam, with an average score of 90 and 29 people passed.
Specific analysis
1. Fill in the blanks: the third question, the seventh question, and 10 are difficult and have a high scoring rate. Other minor questions are easy for students to master and have a high score rate.
2. Calculation part: the fourth item loses more points, accounting for one-third of the class. Students are unclear and need to practice later. The scores of the fifth and sixth items are high, and the law of multiplication operation is not mastered, so students can't use it. There are three digits multiplied by two digits, and the multiplication calculation is not careful, which leads to the wrong calculation result.
3. Problem-solving part: One quarter of the students can't do application problems, don't score, and the failure rate is high. But most students got high marks. In the future teaching, we should have targeted training and guidance.
Third, the improvement and measures
1. Strengthen the training of students' basic knowledge, draw inferences from others, and try to let students master it.
2. For some underachievers, teachers should spare no effort to teach calculation methods and try their best to calculate accurately.
3. To strengthen the cultivation of students' problem-solving ability, teachers should find more problems and practice more. Apply what you have learned to solve problems in real life.
