Chapter 496

"This difficulty upgrade is not too high, right?" Gu Lu replied with a smile in the face of the old teacher's concern.

"The purpose of increasing the difficulty of this year's college entrance examination is to make the grade of candidates' mathematics scores more obvious!" Gu Lu smiled, "I took a look at the mathematics papers of the college entrance examination in recent years, and the test questions are still too simple to completely distinguish candidates of different levels like the Mathematics Olympiad." ”

"But by increasing the overall difficulty of the test paper, I don't think there will be this situation, if it is a diamond, it is a diamond, and if it is gold, it will be gold, and there will not be a situation where diamonds and gold are mixed together as in the past. ”

In fact, for some students with unnatural mathematical strength, no matter whether the difficulty of the test paper is easy or difficult, getting a high score is as easy as drinking tea for them.

But they are actually more willing to make the test paper more difficult.

Because in that case, the grade will be more distinctive, and the excellent people will be as good as ever, but there will be fewer students who are not too good, and the possibility of being the same as the excellent students in terms of scores due to accidental factors.

"However, Professor Gu, in this case, the average score of this year's mathematics paper will definitely drop significantly. Another gold medal lecturer from a well-known educational institution in the proposition group spoke.

Gu Lu smiled and waved his hand, "This is harmless, the average score decline is good, but the admission score line will also decline." ”

"The number of students enrolled by major universities is the same every year, and we don't have to worry about this at all. ”

"What we need to worry about is how to get the results of this year's high school exam perfectly!"

After saying this, Gu Lu's calm gaze swept around everyone, "Do you still have any questions about this decision?"

The five of them shook their heads in unison, "It's gone." ”

Although the decision to increase the overall difficulty of the test paper by one or five times sounds a bit incredible, if you calm down and think about it carefully, you will find that Gu Lu's decision has no other shortcomings except that it will make the average score of candidates drop a lot this year.

Even, this will make the distinction between the grades of candidates more obvious, which is conducive to the recruitment of talents by major universities.

Therefore, after hesitating for a moment, everyone nodded in agreement.

Seeing that everyone had no objections, Gu Lu touched his chin and muttered for a few seconds, and then said in a deep voice, "Since everyone has no objections, the overall difficulty of this year's mathematics paper is set at about 1.5 times that of last year's test paper." ”

"Next, let's get down to business. ”

The proposition work of the college entrance examination can be roughly divided into three links.

The first link is the pre-proposition.

To put it simply, it is to build a test question bank.

According to the syllabus of the proposition group, each person will come up with a certain number of questions with a certain degree of difficulty according to the type of questions they are assigned, and put the questions into the test question bank.

Then, the leader of the proposition group selects the specified number of questions and difficulty levels from the question bank to form a set of official test papers and a set of spare test papers.

After the first draft of the test questions is released, experts will be organized to discuss the test questions collectively, polish the test questions, and reasonably estimate the difficulty of the test questions.

This is the entire workflow of the first part of the whole proposition work.

Gu Lu is now carrying out this link, assigning everyone the type of questions and the scope of investigation to each person.

"Mr. Zhang, you are responsible for the first five questions of the multiple-choice question, and the knowledge examined is still the part of the imaginary vector of the set trigonometric inequality. Lecturer Du, you are responsible for the last five multiple-choice questions, examining the probability and statistics of derivatives elliptic curves, and Professor Ji, I will leave the multiple-choice part to you......"

Gu Lu arranged the tasks one by one.

When it's your turn, only the last two finale questions remain.

“…… I am personally responsible for the last two finale questions, and as for the content of the investigation, it is still the derivatives and elliptic curves. ”

With a simple few words, Gu Lu arranged the task.

"That's it for today's meeting, leaving you with three days to come up with questions, and after three days, I will select questions from the question bank to form a set of first drafts of test questions and a set of backup test questions. ”

Gu Lu announced the end of the meeting.

After everyone said hello to Gu Lu, they left the conference room one after another, and hurriedly went back to the question.

After everyone left, Gu Lu took out a thick stack of scratch paper directly from his bag, took out a pen from his jacket pocket, and began to propose.

Gu Lu had practiced for a long time before he came, and there were only so many knowledge points in high school mathematics, which were just questions of high school difficulty.

In just one afternoon's work, Gu Lu came up with thirty questions with completely different solving skills for the two major questions in the finale.

and list the standard answers in turn.

After checking from beginning to end and finding that there were no mistakes, Gu Lu uploaded a total of sixty questions to the test question bank.

…………

Although Gu Lu said at the meeting that the time left for everyone to solve the questions was three days, in more than two days, the work of the mathematical proposition group was almost over.

This year's college entrance examination mathematics paper is expected to have a total of 21 questions.

In the question bank, there are at least fifty or more alternatives for each question in the test paper.

The difficulty of the test questions varies, and the knowledge points examined are also different.

Looking at the hundreds of pages of questions in the test question bank, Gu Lu rubbed his temples with a headache.

Although these test questions are completely pediatric in Gu Lu's eyes, when the number is accumulated to the unit of 'thousand', it is still enough to make Gu Lu's scalp tingle.

Gu Lu rubbed his hands and sighed lightly, "Let's get to work!"

Gu Lu's next task is to select questions from the test question bank to form a set of test questions in the first draft, and a backup of test questions.

The so-called first draft of the test questions is used for the official college entrance examination.

On the other hand, when there is an unexpected situation in the official test questions, such as the leakage of test questions, an alternative solution will be used to make the backup test questions become the official test questions.

However, in the more than 40 years since the college entrance examination was restored, backup test questions have only been enabled a few times.

There are a lot of test questions, but Gu Lu can basically just glance at the past, and he can understand the knowledge points, solutions, and corresponding difficulty factors of the questions, and then Gu Lu will make appropriate trade-offs according to needs.

Because it originally took two days to select the test questions, Gu Lu completed it all in less than a day.

On the evening of this day, Gu Lu once again called all the members of the mathematical proposition group to the conference room.

Conduct the second plenary session of the Math Proposition Group!

Although only six people attended this meeting, it decided the fate of nearly 10 million candidates across the country.
