Analysis on the types and causes of calculation errors of junior one students

First of all, the type of carelessness

1, missing the question. Some candidates put down a problem and want to go back and do it again. They can finish the next question, but forget it. Some papers are positive and negative? Forget the opposite.

2. Off topic. Some candidates rushed to write without correctly understanding the meaning of the question, and the result was irrelevant; Some candidates can't grasp the direction of answering questions, and forget what the theme is when writing; Some people don't look at the questions carefully, missing words or adding words lead to mistakes in answering questions.

3. Wrong operation symbol. If "+"is regarded as "X" and "plus" as "minus", the result will be a drop in the ocean.

4. the calculation is sloppy. Some students skip the steps in the calculation process, or don't carry them with them, which leads to calculation errors.

5. Copy error. Some students can't use draft paper. On a piece of draft paper, write one sentence in the east and one sentence in the west, and doodle by hand. Some even mix or overlap the calculus of several questions, and as a result, mistakes are often made when copying test papers because of identification errors.

6. careless writing. For example, in the four options of A, B, C and D, this is B, but when writing the answer, it is written as D; Some people write one more word or one less word in the answer, which changes the meaning of the question and leads to mistakes.

Second, the reasons for carelessness

1, lack of understanding of the harm caused by carelessness.

Some students think that carelessness is a minor problem and they can do all the problems. Making mistakes because of carelessness is nothing. Some parents and teachers often say, "This child is very clever, but a little careless." After listening to adults, children will think that carelessness is a small fault that can be forgiven, and even associate "carelessness" with "cleverness". Because teachers, parents and children all think that carelessness is not a big deal, it often leads to carelessness in exams.

2. Usually lack of basic skills training.

Some students usually ignore the training of basic skills and think that it is "pediatrics", so they are not solid and skilled in mastering some necessary basic skills. These students often omit the calculation process after listing the formulas in their usual homework. Even if the teacher asks, they will find some tricks, such as using a calculator or copying other people's answers, thinking that this will save time. Because of cleverness and little practice, I often make mistakes in exams.

3. I didn't carefully examine the questions.

This situation often appears in relatively simple answers. Some candidates are excited and excited when they see relatively easy questions, but at the same time they are impetuous and careless, no longer think carefully, respond hastily and make mistakes; Easy questions are easy to make mistakes. Proposers often hide some problems that are easy to be ignored and omitted in some seemingly simple problems. If they are not careful, they will easily make mistakes. Some candidates judge the types of questions by experience, and when the requirements of the types of questions change, they lose points because of carelessness.

4. The answer time is not properly arranged.

Some candidates think that the previous questions are their own strengths when answering questions, so they can't lose points and take up too much time. When they were doing the following questions, they made a hasty answer because time was tight, and as a result, they lost a lot of points that they shouldn't have lost.

5. Poor sensory integration.

When some students were young, they often wrote more than one picture, less than one, often made mistakes in calculation, and their performance in life was ignored. Most of these mistakes are caused by students' poor sensory integration ability.

6, eager to win.

Seeing that other students handed in their papers one after another, I was unwilling to lag behind, answered hastily and handed in my papers in a hurry; Some students are competitive and always want to be the first to hand in their papers to show themselves, so they handed them in without careful examination after answering them, and as a result, they didn't get the scores they had time to get.

7. Anxiety and nervousness.

Some students are seldom careless in homework and exams, mainly because they are calm, not nervous and can answer questions calmly. Once the key exams are arranged, especially the entrance exams, you will be nervous, sweaty, unable to concentrate, and even confused, leading to reading and writing errors.

8. I am eager to answer questions.

Some candidates think that the exam is a race against time, so they should answer the questions as soon as they get them. When the invigilator turns a deaf ear to the instructions and requirements in the test paper, he often answers the wrong question because he doesn't hear the teacher's explanation clearly or misreads the meaning of the question.
