Qi Binxuan thought while preparing the courseware. Hmph, loud and aggressive, we have been soldiers, and the momentum and volume will be poor?

I like to hunt for curiosity, no problem, who are we, the owner of the Maker Tea Society, can there be fewer strange things?

Don't follow the book, I like to listen to Kan Dashan, okay, the textbooks are thrown aside, we also have rich life experience, and we have read hundreds of novels, can we still lack stories?

If you like the standard answer, well, I'll deprive you of the thought process and give you a standard answer.

After some careful preparation, the time for the third class arrived.

Qi Binxuan walked to the classroom, saw that the classroom was basically full, and roughly counted the students, and felt that there was nothing to skip class. Thinking about it, I've spoken, and this time it should be almost the same.

Qi Binxuan said: "It seems that everyone came together this time." To be honest, I was angry that you skipped so many people last time. You are disrespectful to your teachers, and you are disrespectful to yourself. You are here to study, you don't have a good grasp of the knowledge of your major, and you still have the heart to study other things? If this happens again, those who skip school without reason will have to fail the course. I know you might be interested in some new ways of teaching, okay, then I'm going to change my teaching thinking. Let me start with a question. In the first lesson, we talked about the first chapter. So the first knowledge point, what are the three aspects of structural reliability? Don't look at the textbook, okay, that student answered. Don't look at anyone else, it's you. ”

The classmate who was pointed at by Qi Binxuan stood up, opened his mouth for a long time, and finally said a sentence: "I'm sorry, teacher, I don't know." ”

"Well, it seems that the first class was not very efficient. Okay, I'll go through that again, and then you'll answer it. If you answer correctly, then you sit down and listen to the lecture, and if you make a mistake, you will be wronged to stand in the corridor by the wall and listen to the lecture. ”

Qi Binxuan said, wrote four words on the blackboard, and said: "The reliability of the structure includes three aspects, safety, applicability and durability. This is a must for builders, how to memorize it?"

As he spoke, Qi Binxuan circled a circle on the four words: "We take the suitability of 'applicability', the resistance of 'durability', and the safety of 'safety', which together are 'suitable for safety', and the homonym is 'Shi Nai'an'." 'Reliability' takes the word 'reliable'. Then the mantra of this sentence is, 'Shi Nai'an is very reliable'. Associative memory, Shi Nai'an wrote the Water Margin, such a long novel, insisted on updating it, what a reliable person. Okay, have you memorized the knowledge of structural reliability?"

The students in the classroom all whispered, buzzing together, like a swarm of flies making a noise, making people upset.

Qi Binxuan patted the back of the blackboard on the table and said, "Don't talk nonsense in class, raise your hand if you have a problem." ”

As a result, no one raised their hands.

"Okay, no problem, the standing classmate, you answer, what are the three aspects of structural reliability. Hey, with your eyes closed, it's still written on the blackboard. ”

Qi Binxuan's words caused the students in the audience to chuckle again, but they were all quiet after being glared at by Qi Binxuan.

After the standing classmate answered correctly, Qi Binxuan motioned for him to sit down.

Okay, let's move on to the second point. Five forms of force on structural members. According to their deformation characteristics, the basic force forms of structural members can be summarized into five types: tension, compression, bending, shearing and torsion. The simple memory is, tension, compression, bending, shearing and twisting. But how do you remember these five words? We can use the image memory method. Two classmates came up to help. Okay, Tang Chengzi, Zheng Jinglian, it's just the two of you. ”

Tang Chengzi and Zheng Jinglian went to the podium with tears and sad faces.

"Hey, be happy. It's good to work with the teaching. Why? Because you can add one point to the final exam. Qi Binxuan's words caused an uproar again.

Qi Binxuan asked Tang Chengzi to take off his coat, roll it into a rope shape, let the two classmates pull one end each, and then pretend to be a tug-of-war.

Qi Binxuan continued: "Just pretend, don't be so hard, I won't pay if my clothes are torn." Okay, everyone looks, during the tug-of-war, they each have to pull back, and then lower their bodies and bend down in order to exert their strength better. In this action, the words 'pull, pressure and bend' come out. ”

Then Qi Binxuan gestured with his hand to make a scissor motion and cut it down on the middle of the clothes: "When they are tug-of-war, what will happen if I cut it in the middle? They will fall, and there is a high chance that they will twist their waists." This is called 'shear twist'. Okay, pull, press, bend, shear and twist, who else has any objections to this knowledge point, have they all remembered? As for their respective meanings, it is very simple, just look at the illustrations in the textbook. ”

Qi Binxuan asked a classmate and asked him to memorize this knowledge point. "Hey, how are you peeking, your eyes are not closed. You just turn your back and carry it. Then there was another burst of laughter.

"Okay, let's move on to the third point. There are several causes of earthquakes. There are three types of earthquakes: volcanic earthquakes, collapse earthquakes, and tectonic earthquakes. Or take one word each, 'collapse fire'. How do you memorize it? Think about it for two minutes. ”

Two minutes later, Qi Binxuan asked everyone if there were any good ways to memorize, but no one answered. Qi Binxuan said: "You still need to expand your thinking and use your brains." Let me tell you a little story to associate with memories. Everyone knows about the ghost step dance, it was very popular some time ago. Suppose there is a flash mob event, everyone gathers in the square and dances together, and the result is a big scene, and the pace is the same, making the ground shake, like an earthquake. Why does there be an earthquake? It's because the ghost dance is hot enough. 'Earthquake he's fire enough', remember?"

"Okay, let's talk about the fourth knowledge point......

The class of interest passed quickly, and after a while, the bell rang for the end of class.

Qi Binxuan said: "Okay, everyone listened to this class very seriously. Next, assign the homework. In addition to the after-class exercises, everyone should preview the following chapters, not only to understand the knowledge points, but also to make up their own formulas or short stories to assist in memory. The class representative will divide the next chapters into three pages each, give two weeks to compile the knowledge points in them, and finally collect them for me to check. The mantra is based on ten, and if you exceed one, you will be rewarded with two points, and if you are less than one, you will be deducted one point. The upper limit is 30 points, and the lower limit is negative 10 points. Do you understand? Okay, let's get out of class. ”

The students left the classroom with a strange feeling. This class gave a deep impression to everyone, the teacher's way of teaching has changed, and the class has become interesting, but it seems a bit difficult to make up stories and hand in homework by yourself. And how can a good engineering department have a feeling of becoming a liberal arts.

In the bedroom, Gao Shenghan sat at the desk, scratching his ears and cheeks, unable to calm down, he looked at his pages, and couldn't make up recipes or stories. He asked Tang Chengzi, the little fat man next to him: "Do you know how to make up formulas?"

"Okay, I made one up. ”

"Really? Let me see. Saying that, Gao Shenghan took Tang Chengzi's notes and read them, and Shi Qingying and Zheng Jinglian also came over to learn from them.

"The degree of damage to buildings in an earthquake is generally heavier than that of beams, the seismic damage of the top of the column is heavier than that of the lower column, the seismic damage of the corner column is heavier than that of the inner column, and the seismic damage of the short column is heavier than that of the general column. The mantra is: the top and bottom corners of the column and beam are generally short. Do you take one word for each word and make it a formula, can it meet the teacher's requirements?"

Tang Chengzi said with a strange smile: "I used to study memory courses, and what the teacher said was basically to connect memory with knowledge points through a story or object shape. The more weird, unreasonable, and peculiar it is, the more impressive it is, so as to achieve the purpose of memory. So, I also memorized this mantra vividly. That's the word 'mouth'. ”

"What does that have to do with this formula?" the three of them asked, confused.

This mouth can be divided into five components, vertical, horizontal, folded, hooked, and short. The first stroke is vertical, representing the column, the second stroke is horizontal, representing the beam, the third stroke is folded, the order is from top to bottom, representing the top of the column and the ground of the column, the fourth stroke, turning from the corner to the inside, representing the corner column and the inner column, and the last stroke is short and horizontal, like a short one, representing the short column and the general column. When the strokes are connected, the memory is 'the top and bottom corners of the column and beam are short'. Didn't there be a saying in the past that there were several ways to write the word back? I called it a few ways to write the word "word". You can write a circle clockwise, and write it once to read the mantra. Well, this mantra is okay, right?"

Gao Shenghan just wanted to praise two sentences, but Shi Qingying said: "You are really verbose, look at me." My knowledge point is that the height of the handrail of the indoor staircase should not be less than 0.9 meters from the front edge of the step. 'Take the keyword, raise the front edge nine, and the homonym is 'vice high thousand yuan wine'. How about it, deputy senior engineer, when you have a treat, you have to drink 1,000 yuan of wine, the image is vivid, simple and easy to remember. ”

Zheng Jinglian said beside him: "Your knowledge point is just a number, so little, of course it is easy to make up, and the difficulty cannot be compared with Xiao Tang's." The knowledge point I compiled is also long, and it is more brilliant than the two of you. My knowledge point is the three cases of crack control in concrete structures. First, there is no tensile stress in the construction, second, although the component has tensile stress, it does not exceed the tensile strength of the concrete, and third, cracks are allowed, but the crack width does not exceed the allowable value. The first one takes the key words 'no' and 'pull', the second takes 'pull' and 'tensile resistance', and the third takes 'seam' and 'not exceeding'. The mantra is 'no pulling, no stretching, no stretching, no exceeding'. ”

"Your mantra is a bit reluctant, and it's not easy to remember. Shi Qingying also retorted.

"Don't worry, I don't have associative memories yet. Zheng Jinglian continued: "Didn't there be a promotion of Du Lala before? Bu Lala is a master of practicing Wing Chun, when she is doing Wing Chun, two people pull her knees to both sides, she resists the pull force, the gap between her thighs is no more than five centimeters, reaching the master level. This is 'no pulling, no stretch seam is not exceeding'. How's it going, okay?"

The three of them were silent, and Shi Qingying said: "Well, although there is no evidence, I suspect that you are driving, and you hand it in, do you say that the teacher will give you two copies, or will you deduct two points?"

"Huh, isn't it appropriate?" Zheng Jinglian asked suspiciously, still with a paralyzed face.

The three of them nodded in unison.

Zheng Jinglian sighed and said, "Hey, forget it, I still want to make a splash after handing it in." ”

"I don't know if it's a blockbuster, but it's definitely shocked. Tang Chengzi quipped.

Gao Shenghan saw that the three of them had made up formulas, but he didn't have a clue, so he said: "Which of you can help me make it up, whoever made it up I invited him to dinner." ”

All three shook their heads in refusal. "No, this is not easy, I made up a number of brain cells that died. "yes, you see I made one up, and you can't tell you about it. "You'd better work on your own, we may not be able to complete the task ourselves, we can't really help you." ”

Hey, how should I complete this task, I am the class representative, will I double the points if I can't complete the task, Gao Shenghan fell into deep thought.
