Last Friday's monthly exam has ended, and the overall effect of senior two mathematics is far from my expectation. The content of this exam does not involve the content of the seventh unit of the textbook "Observing Objects", and the other six units are involved to varying degrees.
The following analysis points and reasons:
There are many missing points in the fill-in-the-blank questions, such as the scale calculation of the ruler, the filling of the maximum number, the rewriting of multiplication and division, the addition of at least a few digits to the number divisible by 5, and the comparison between numbers. The reason is that the questions are not accurate, the solidification of thinking is a stumbling block, and the questions are flexible and diverse, so it is difficult for them to simplify the questions.
No student's judgment on the problem is correct. In my first question, I haven't talked about judging the relationship between units according to the progress rate of meters and centimeters. Don't make mistakes in other minor problems. Judgment is a key point in my future teaching.
Among the multiple-choice questions, the third item examines the number of RMB sheets and shopping, which is based on the content of Jiao Yuan, a freshman. It should not be difficult. However, there are many wrong students, which shows that the price of physical objects and the conversion of several yuan are not well mastered. The fourth problem is to find the original length of the ribbon after being folded in half twice. This type has also been mentioned, and it should not be wrong. In the future, let the students do it themselves, find out the number of copies and learn to convert and calculate.
In drawing questions, some students did not draw a complete line, and the length of the line was not carefully examined and calculated. Calculation problems, individual formulas are memorized incorrectly, and the whole is ok. But my expectation is that there are no mistakes. I want to move towards this goal, review the easily confused formulas together, review the classification again, and urge students to look at the operation symbols correctly at ordinary times. In addition, the irregular digital writing of individual boys has always been a headache for me, such as: 9 is not sealed, and the difference between 0 and 6 is not obvious. Writing norms, but also expensive in ordinary, can not be made do with.
In solving the problem, there are two questions in the third question. Some students confuse the two questions or ask only one question. The fourth small problem is that the relationship between the number of pages and the number of days is not clear and the formula is wrong. Look at the formula and write the meaning for the last little question. Usually, there is no special training. If the students write incompletely, the meaning is not clear. This is also the focus of future exercises. It is necessary to cultivate students' thinking and ability to draw inferences from others and simplify the complex, so as to clarify the relationship, straighten out the relationship and choose the correct operation, which is a step closer to flexible learning and application. At present, the problems are diverse and the content is not very direct. In order to solve all the obstacles in the examination paper, we must develop our thinking and pay attention to the basic knowledge, so as to apply what we have learned and find and solve problems in life.
