Beijing college entrance examination found nine cheating one of them wrote the answer on the legs diesel generator | diesel generator price / 2012-06-16
Yesterday afternoon, the entrance examination score was briefly opened to the media.

Cheating candidates will be punished with the violation of the general academic record. According to the Municipal Examination Institute, the college entrance examination has entered the formal evaluation stage. The total number of markings this year is 270,989.
Cheating candidates cancel the general performance
Yuan Xiaolian, director of the high recruitment office, introduced nine cheating activities during the Beijing college entrance examination this year. Four of them carried a mobile phone, three had a slip of paper, one had been guilty of procrastination, and one had found the answer written in their legs. They will be punished in accordance with the new examination regulations and cancel the results of the general examination.
This year, the inspection of the same roll was strengthened during the marking process. However, at present, the probability of finding a similar roll is very small. The head of the Beijing Examination Institute, Miao Tiejun, introduced that radio cheats of a large scale are likely to appear in similar volumes. At present, the inspection of high-tech cheating is very strict. In addition, if the plagiarism with the examination room may also produce similar volumes, but Beijing's examination room setting norms, but also through the examination room monitoring video screening, so in recent years this situation decreased.
270,000 papers to be reviewed
According to the Municipal Examination Institute, a total of 69,191 candidates took the college entrance examination this year. At present, all subjects in the college entrance examination have been closed and a detailed marking standard has been formulated and entered into the formal evaluation stage.
According to reports, all the subjects of this year have adopted online assessments. The city has a total of 6 reading points and the total number of readings is 270,989, which is approximately 10,000 less than last year. The entire assessment will end on June 22, and the results will be announced to the public on June 23 and notified to every candidate.
Relevant universities and districts and counties have rigorously selected the evaluation teachers and have reached certain qualifications to qualify for the assessment. It is reported that the scores of teachers must have more than 3 years of teaching and teaching experience, and have intermediate or higher titles; the title of the team leader must have more than 5 years of experience in teaching and teaching and research, and have a higher grade than the above; the subject leaders must have more than 7 years of experience. Teaching and teaching experience, associate professor or above. Undergraduate (or below) undergraduate students are not allowed to participate in the marking process.
Marking the whole subject back to back and double evaluation, to eliminate the occurrence of missed judgments, misjudgment. Each section has a quality inspection team composed of seasoned experts, sampling inspections within a certain range at any time to ensure the quality of marking. The risk management and daily report system will be implemented throughout the evaluation work. Each evaluation point will report the situation to the Beijing Education Examination Institute on a daily basis.
In accordance with the requirements of the Ministry of Education, the city has also established a leading group for the assessment of college entrance examinations, and set up an arbitration group. According to the person in charge, "This group is mainly responsible for adjudicating the same volume, and at the same time identifying the paper with doubts about the subject group."
The teacher is leaked when interviewed
The teacher of the language review group, Qi Yongxiang, said that the manuals handed to the teacher were much thicker than in the past. They strictly implemented schoolbags, mobile phones, etc. The readers were strictly forbidden to bring the scoring rules and sample volumes to the reading point. We use other classroom training, sample volumes also need to be fully received before the collective transfer to the engine room. We call it 'see light dead.' For better confidentiality, this year's language reading room will be the entire second floor of the engine room closed.
Yan Tiejun also added that any assessment teacher can not explicitly bring the answers, scoring rules, and scoring documents out of the review point this year. These are all state secrets. “If the teacher is interviewed, it is a disclosure, and the reporter’s interview is confidential and there is no decryption. period."

Well-written essays are especially rare
Composition writing has always been of concern, and the teacher of the language review group, Qi Yongxiang, introduced that in order to make the score more scientific and rigorous this year, the reading group spent 4 days to conduct a review and determined the scoring rules. In contrast to other topics, even if the progress is behind, the teacher of the composition group cannot be replaced once selected. “Because the teacher of the composition group is very difficult to train, we are not moving for the composition teacher.†As a high school language teacher, because high school language teachers have experience in essay scoring, the ups and downs will not be too great. However, at present, some doctoral students who have had the experience of self-selected composition examination will be added to review the composition.
This year's essay questions for the Beijing college entrance examination are generally very easy to reflect, but Qi Yongxiang stated that it was difficult to distinguish between different grades when writing a review. "There are no full score compositions at present, and this year probably won't be a full score composition." According to reports, compared with last year's college entrance examination, there were a total of 11 full score compositions.
The marking teacher needs to answer the question first
This year, there has been a big change in the language review group. Whether it is in the test paper or before the formal review, each scoring teacher will need to do his own examination paper and give them the answer afterwards. Qi Yongxiang said that this is done so that the scoring teacher has a personal feeling of the answer, and the score can be more accurate.
Before this year's college entrance examination, the media made extensive coverage of the current year's adjustment request questions using the current rules governing Chinese language. Therefore, Qi Yongxiang stated that the use of Internet characters, network bodies, and non-canonical acronyms are rarely seen this year. However, he said that if it is appropriate to quote online language, it is allowed, but it cannot be used to organize language confusion, reverse the order, or even only understand the Internet stylistic questions.
With regard to the use of traditional characters, Qi Yongxiang stated that the new rules do not prevent the use of traditional Chinese characters because traditional characters are still used in Hong Kong and Taiwan, but traditional characters are discouraged, but points will not be deducted if the traditional characters are not mistyped.

Mathematical Synthesis Requirements Zero Error
The person in charge of the Department of Biology and Biology explained to Benchion that all reviewing teachers must first pass their own assessments and confirm that they have fully mastered the scoring criteria before they can formally review the documents. Although the comprehensive theory is an objective question, it is also a double-evaluation system. Different from the subjective questions such as composition, the comprehensive evaluation of the paper requires zero error. This is not only the same as the title scoring requirement, but even the score of each scoring point must be the same. Arbitration is required whenever there is a difference.
Miao Tiejun introduced that in addition to the comprehensive academic subjects, the current mathematics also achieved a zero error rating.
