How do you plan your own earthquake prevention and disaster reduction science to explain the competition works

Before the Spring Festival, the China Disaster Prevention Association has issued a notice on the launch of the Second National Science Bulletin on Earthquake Disaster Reduction. As time approaches, the young race officially entered the second quarter.

The author once participated in the inaugural event, winning the championship from the selection and preliminaries, all the way to the finals, and was awarded the title of “Accident for Earthquake Disaster Reduction”. Before the advent of the second season, think about the need to talk to someone who will soon participate in the competition - how to plan their own work on earthquake prevention and disaster reduction science.

One of the differences: In addition to the optional explanations, a lottery and technical knowledge Q&A sessions were added.

In order to further match the requirements of the National Science Popularization Contest held by the Ministry of Science and Technology, the second session of the Earthquake Prevention and Mitigation Science Popularization Contest took place with the addition of a sample selection session. The scope of the selection will be synchronized with the content published on the website of the Ministry of Science and Technology. This is also for the participation of the winners. National sciences explain the rhythm needs of the contest.

Drawing pictures to explain from 20 randomly selected one, players expand no more than two minutes to explain the content of the photo, visit the comprehensive knowledge and skills to master the science of players. Of course, to be on the safe side, the competitor should make preparations for explaining the 20 photos. The 20 pictures in 2017 as the range of selection include: Pythagorean theorem, VR , AR , Beidou, virus, tea, brain, electromagnetic, light, genetics, antibiotics, flammable ice, radio telescope, cloud, space station, Li Shizhen, Qian Xuesen, biometrics, artificial intelligence, acupuncture.

The quiz for science and technology is also a form of selection. Two questions are selected in the "China Citizens' Science Quality Benchmark". The questions are selected or judged. Of course, the "benchmark" is still very large. It is necessary to ensure that the two questions in the drawing are answered correctly. All questions on this benchmark must be known. How many questions do you need to ask for a benchmark? 500 questions whole!

The second difference is that the number of awards has increased.

In the first tournament finals, 3 first prizes were awarded, 4-10 were second prizes, and 11-20 were third prizes. The number of winning prizes in the second round of the tournament was adjusted to be the first prize in the final 3 before the finals , 4-15 as the second prize, and 16-30 as the third prize.

Judging from the promoters' driving force, the number of applicants for the second race is expected to exceed that of the first session, and the number of excellent explaining works will also have a larger increase. Relaxation of the final winning percentage will help encourage more people to actively participate in the event. Earthquake prevention and disaster reduction popular science to explain the creation of works.

How to plan a good tutorial

Of course, popular science explains the top priority of the competition, or four minutes of self-selected works.

First of all, the selections only look at the works of their choice, and the selected works will enter the preliminaries. The selection of lectures and the quiz for science and technology are the contents of the preliminaries. Secondly, even in the various aspects of the preliminaries, the proportion of the self- explanatory works is also Up to 70 %.

1,

For a four- minute science popularization work, the topic should be as small as possible, start with a specific knowledge point or a certain technique, and be thorough and complete around this knowledge point. This work has a successful framework.

Do not seek to explain the scope of too much in the 4 minutes, highlighting too much knowledge points, experienced science popularization of the person who speaks clearly, one-time speaking to the object of speaking too much knowledge, will cause the memory point is not concentrated and the effect is poor. For example, try not to have such problems as "What role can the seismic stations play" and "What new technologies are available for earthquake emergency rescue?" The intention is too great, and it cannot be thoroughly explained in an effective time.

Starting from a small knowledge point, by analyzing the language of the knowledge points and other auxiliary expressions, help the audience to build the ability to understand this knowledge point, and accept the way of thinking to explain people. This is the core pursuit of popular science work.

The four- minute science explaining work contains very important layout and rhythm control requirements. It should be divided into several sections for explanation. It is divided into four parts with every one minute as the boundary . Each part is connected with each other, logically coherent and independent. Each has its own emphasis.

Copywriting case

The first minute: come straight to the top. We can consider the introduction of some cases for the theme of the preaching, such as the earthquake case of a major earthquake and the difficult situation of a post-disaster rescue. The case to be introduced should have a logical connection with the theme of the preaching, and the case itself should have Attraction, regardless of whether this attraction comes from the content or form of the case. When the case is attractive, the audience's attention will be smoothly transferred to the topic itself. The introduction of the case should be controlled within 30 seconds as much as possible. Before the end of the 1 minute, we must basically present the theme of the presentation.

The second minute: Pading solution cattle. This period of time should concentrate on the scientific explanation of the topic of the topic of the discourse. Note that the explanation of scientific principles should be straightforward and easy to understand. Try to use analogy and association methods and use common examples in life to allow listeners to have a conceptual understanding of the principles themselves. This period mainly involves expounding the scientific principles. It is a great test for the proponents to use the reform of the popular science language. Explaining whether it is lively or not is directly related to whether it can extend the audience's attention. In particular, it should be noted that this period of time is a centralized analysis of the topic information, and the amount of information in the organization cannot be too full. Don't let the audience remember too much information at a time. Studies have shown that most people can remember no more than 4 items at a time. Too much information at a time will have a negative effect on the audience's understanding and memory.

Third minute: Strengthen consolidation. This period mainly reinforces and strengthens the understanding of the previous scientific principles. The popular science presenter introduced a new information point that needs to be remembered. It must be reinforced with examples or exercises in order to shift it from the general impression of the audience to long-term memory. Note that examples or cases that are understood with knowledge points cannot be complex and are based on the principles of simplicity and effectiveness.

The fourth minute: finishing touch. In general, the stage where listeners receive the most attention in information is concentrated on the beginning and the end. Therefore, the importance of content organization in the final stage is undoubted. An excellent popular science propaganda work must be a “crested tail”. The “pointing eye” pen of the ending can be started from the extension of the preaching theme, designing one or two inspiring topics, or simple application cases, as well as expectations for the future, and the emphasis on the refinement of the preaching theme. Strengthen your memory.

Finally, we must pay attention to the overall understanding: Do not timeout. According to the principle of competition in the competition, the points that are deducted once they are overtime cannot be remedied, no matter how excellent they are. According to the explanation, the normal speech rate of the person is 3-3.5 words per second , and the number of words to be interpreted in 4 minutes should not exceed 750 words. In addition, an excellent explanation of works should be given to the audience and consideration for the audience should be given more attention. The number of words in the control copy.

Explaining means to enrich is an inexhaustible requirement. In general, explaining means includes explaining projections, explaining props, and setting up scenarios. There are two ways to explain the reasonable collocation of the means: one is to help the audience understand the topic of the explanation, and the other is to capture the eyeball creatively.

[aesthetic expression]

The design of entries should fully take care of the artistic processing of ppt . A good science explanation and a high request to speak is a beautiful explanation. Beauty is a fusion of human interpretation and auxiliary projection art effects. When a person walks in a painting, the picture presents a change of rhythm with the rhythm of the explanation, which can form a good aesthetic interaction with the audience.

In particular, it is necessary to point out that in the higher-level interpretation of competitive sports in popular science, there is no question of partiality and unbiasedness in the theme, explaining that the level of ppt and the art of drawing and painting are in harmony when the attitude, pronunciation, etc. can no longer be opened . Requirements will become decisive factors.

Background music and video are part of the rich representation of ppt , but for audio and video presentations, they also have to bear certain technical risks. One is the video compatibility issue, and the second is whether the match between the background sound of the game and the vocal microphone can be achieved comfortably and effectively, which puts forward higher requirements for on-site debugging and running-in. It is of course good to work well, and it is hard to break it down.

[proper use of props]

Props that match well with the topic are common extra points. Props can be used for daily life items and can also be customized. The principle of selection of props is to allow the audience to understand the connection between the props and the theme without much thought. On this basis, props also need to consider the purpose of "eye-catching."

[stage rhythm grasp and other]

In terms of expression skills, the science commentary should be vocal standards, clear-cut, well-dressed, and these are the basic requirements for popular science scores. Beyond this, attention should be paid to physical expression, standing can not be changed, switching of standing and gestures, explaining the frequency of people moving back and forth in the stage, etc., all contribute to attracting the audience's attention with external means. These need to be studied repeatedly in practice, with the interpretation of the theme, to achieve the aesthetic balance.
