What do you think of computer marking for senior high school entrance examination?

The software used is Beijing Mayuxin Computer Aided Marking System, which is very scientific in software design. Taking chemistry marking as an example, an expert group was set up to divide the marking teachers into four groups and assign marking personnel according to the difficulty of marking each group. Each group has a machine with a unified number and is not allowed to walk around. Each group has a team leader. Before the marking begins, the answers will be explained and unified on the morning of 26th, and then the online marking will be conducted to discuss the problems in the students' answering process again and form a unified opinion. After the official opening of the review in the afternoon, each paper will have one evaluation and two evaluations. After the first marking teacher gives the score and submits it, the test paper will be automatically assigned to the second marking teacher by the computer system, but the second marking teacher does not know the score given by the first marking teacher. The marking interface is exactly the same as that of the initial evaluation teacher. If the scores given by the first evaluation teacher and the second evaluation teacher are inconsistent, the paper will be automatically handed over to the group leader for three evaluations and the final score will be given. Therefore, any chemistry test questions in the last two years require zero error.

Problems found in the examination paper

(1) papers should be kept clean and standardized.

Judging from the feeling of marking papers, the text effect of scanned papers is slightly worse than that of papers, which requires candidates to pay attention to the standardization of writing when answering questions, try to avoid smearing and sketching, try to make the fonts beautiful and generous, and don't crowd together, so that people can't tell what they wrote, resulting in losing points.

(2) Be careful not to write typos.

Judging from the test paper, some students' language ability is really poor, and some common words and important words are written wrong, resulting in losing points. Generally speaking, chemical marking will be lenient to typos unrelated to key knowledge, but typos related to key words are definitely unacceptable. For example, "element" is written as "element"; "Lime water" is written as "Carboniferous water" and "impure gas" is written as "impure gas"; "Engine oil" is written as "chicken oil" and so on. These examples show that some middle school students have poor writing ability. For most students, as long as they pay attention to this problem, they can avoid the above low-level mistakes.

③ Strengthen the training of chemical terms.

Judging from the examination paper, many students' application of chemical terms is not accurate, and there are many inappropriate mistakes. This may be because junior high school chemistry study time is relatively short and students can't master it well. Such as "H2O" written as "OH2"; Writing "NaHCO3" as "Na2HCO3" has caused great problems in the writing of chemical equations, and the scoring rate is relatively low.

(4) The problem of sloppy examination is very prominent.

Some students should be able to, but they will lose points if they don't pay attention to the requirements of the topic. If you are asked to write A or B and the result is A or B, you will lose points, and you will also answer irrelevant questions and wrong answers. These should not appear, so you need to pay attention to training.

3. It can be used for reference in our work.

The marking of the college entrance examination is similar to that of the senior high school entrance examination, and the problems and feelings we encounter will also be encountered in the college entrance examination. Therefore, it may be effective to solve some bad habits of our students in the process of answering questions, and take the senior high school entrance examination papers as an example to make our students wake up from other people's failures. Students who do not pay attention to standardized answers will pay the price.
