1. 1、 The background and significance of the research, number and calculation is the most widely used mathematical knowledge in people's daily life, it has always been the basic content of primary school mathematics teaching, and cultivating primary school students' computing ability has always been one of the main goals of primary school mathematics teaching. However, for a long time, the so-called primary school calculation teaching often through mechanical repetition, a large number of topic training, only pay attention to the results of the calculation, and do not pay attention to the calculation process, students do not like the class about calculation teaching, for them, calculation is often endless exercises; Even teachers don't like the teaching of computing. In the teaching of open class, we seldom see the figure of computing teaching. Since the implementation of the new curriculum, the teaching of computing has been greatly improved, but in the teaching of computing, there are some teachers who overemphasize the diversity of computing methods, and the teachers have not played a very good leading role. The classroom is full of "how do you think", "are there any other different algorithms", "how do you like to calculate". In 40 minutes of classroom teaching, you often talk to me. Obviously, we find that although students' thinking is active and the scene is noisy, students' discussion and communication occupy most of the time in the classroom, and there is no necessary practice in the classroom. After that, we find that students' computing ability has declined: many students do not understand the theory, Results the calculation error rate is high, and the calculation speed of many students is greatly reced. It is beneficial for everyone to form a certain computing ability in primary school, and the process of learning numbers and calculation is the process of cultivating and developing students' logical thinking ability. Throughout the primary school mathematics teaching, the calculation teaching occupies a considerable proportion, just look at the textbook directory can be understood; And in the teaching evaluation, the proportion of calculation is also obvious. From a simple point of view, the calculation of 100 points accounts for 40 points, not including the calculation in comprehensive application. In this regard, we put forward the topic of "how to improve the practice and research of primary school students' computing ability". We want to overcome some disadvantages of computing teaching through the practical research of this topic, so that our computing teaching is full of vitality and vitality, which can significantly improve students' computing ability, and let students like to have computing class and do computing problems. 2、 Pedagogy tells us that teachers play a leading role in teaching activities, while students are the main body of learning. China's famous ecator Ye Shengtao also clearly pointed out: "teachers must inspire students' initiative and guide them to explore as much as possible." The common activity process of teachers' teaching and students' learning depends on whether students are willing to learn. Students do not take the initiative to learn, it is not enough to rely on the teacher's hard work. So "teaching" must combine the teachers' serious explanation with the students' active input, in order to receive good teaching effect. 2. Confucius said, "those who know are not as good as those who are good, and those who are good are not as happy as those who are happy." Primary school students are in the stage of image thinking, they are lively, easy to accept lively, infectious, interesting things. Therefore, only when any ecation really stimulates students' interest in learning, can it achieve the maximum benefits and make interest the best teacher for students. 3、 Research status at home and abroad, according to the requirements of China's "mathematics curriculum standards", cultivate students' thinking ability, operation ability, spatial imagination ability, ability to solve practical problems and innovative consciousness. Among them, it is very important to cultivate students' computing ability. In the process of deepening the new curriculum reform, as a front-line mathematics teacher, more and more feel that students' computing ability has declined. Many schools have also carried out some research on this aspect, such as: situational teaching method to improve students' interest; Take care of students' psychology and arrange their homework at different levels; Let students full of confidence in the competition incentive method and so on. Throughout the world, most of the countries have higher requirements on the cultivation of students' computing ability. For example, although the UK does not approve of trivial written calculation, it attaches great importance to the cultivation of mental calculation and estimation ability; In the newly revised curriculum syllabus of Japan, it is clearly proposed to increase the teaching time of Mathematics for "repeated training of calculation". This topic will make full use of the existing experience and theory of computing teaching at home and abroad, on the basis of the existing investigation, research and analysis results at home and abroad, and fully combine with the actual computing ability of students in our school, to further discuss, and strive to build teaching methods and teaching strategies in line with the actual situation of our school ecation. 4、 The main objectives of the research are as follows: 1. General objectives: through the research of this topic, while effectively recing the burden of students, we should strive to improve students' computing ability, cultivate their oral, mental, estimation and written abilities, realize the organic combination of diversification and optimization of algorithms, and promote students to graally like mathematics in a lively and relaxed learning atmosphere, Interested in computing. So as to improve students' academic performance and lay a solid foundation for students' future study. 2. Students' goals: 1. Set up correct learning goals and hard work goals, study consciously and form good calculation habits. ② Students learn to allocate their time independently, organically combine in class and out of class, infiltrate and promote each other. The overall computing power has been improved. ③ Let students improve their computing ability in a relaxed and pleasant learning atmosphere. 3. Teachers' goals: facing the confusion in the new curriculum reform, teachers should be good at discovering, diligent in learning and brave in innovation. Constantly improve their ability in all aspects, have the courage and ability to solve new puzzles. ② We should try our best to find a teaching method and mode that can effectively rece the burden of students, effectively cultivate the ability of calculation and innovation, and promote students to study lively and actively, and graally form their own teaching style and school characteristics. 5、 The content of subject research traditional computing teaching often adopts such a mode: basic training (bedding practice) - Example Teaching (summary rule) - repeated practice (forming skills). In this kind of "pure computing" classroom, the teaching goal is always to remember the calculation rules and form calculation skills, so the classroom of calculation teaching has become a pronoun of monotony, boredom and boredom. In order to deepen the teaching reform, the effective calculation teaching is implemented in the classroom teaching. We divide the research content into four parts: 1. Research on promoting students' good calculation habits. Some students have low computing ability, of course, there are some reasons, such as unclear concepts, no real understanding of computing theory, no proficiency in algorithms and so on, but not forming a good habit of computing is also one of the important reasons. Some of them have bad habit of examining questions, and they often do it after half reading; In some cases, the writing is not standardized, the numbers and operational symbols are scribbled, and the numbers and symbols are copied wrongly; Some people don't have the habit of checking the calculation, so they just finish the calculation. In view of these phenomena, we think that in order to improve students' computing ability, we should first start from cultivating students' good computing habits, so that students can master some computing methods. We will study how to promote students' good calculation habits in classroom teaching, student practice and school activities. 2. How to use classroom teaching to improve computing ability. Dominated by the traditional teaching concept, many teachers adhere to the principle of "practice makes perfect" and implement the "problem sea tactics" in the teaching of computing, which makes more and more students hate and fear computing. Reading the new curriculum standard carefully, it is not difficult to find that the requirement of calculation mentioned "attach importance to the cultivation of students' innovative consciousness and practical ability". This requires us to actively change our teaching concept, and put the teaching goal more in the thinking process of computing itself, and how to carry out the teaching and learning activities of computing, so that students can actively and happily participate in computing, feel the charm of computing, taste the fun of computing, and improve the ability of computing. Therefore, we will study how to use teaching strategies and methods to make students really love and understand computing. 3. To realize the research of algorithm diversification and optimization“ Encouraging algorithm diversification "is an important concept of the new curriculum standard. The essence of algorithm diversification is to let students learn new knowledge from their existing knowledge and experience, and encourage students to explore problem-solving methods through independent thinking, which has received great attention and positive practice from teachers. We will study how to grasp the essence of algorithm diversification in mathematics teaching, deal with the relationship between algorithm diversification and algorithm optimization, and pursue the rationality and flexibility of algorithm. 4. Strengthen the research on the teaching of oral calculation and estimation. Oral arithmetic, also known as mental arithmetic, is a way of directly calculating the number without the help of calculation tools, mainly relying on thinking and memory According to the new curriculum standard, oral arithmetic is not only the basis of written calculation, estimation and simple calculation, but also an important part of calculation ability. It can be seen that the first step to cultivate students' computational ability is to start with the ability of oral calculation. In the aspect of developing students' number sense, mathematics curriculum standard clearly points out that it can estimate the result of operation and explain the rationality of the result. Estimation is one of the effective ways to develop students' number sense, and it is also an important link to ensure the correct calculation, which is very beneficial to improve students' calculation ability. By estimating before calculation, we can estimate the general results and create conditions for the accuracy of calculation; Estimate after calculation can judge whether there are errors in calculation, find out the causes of errors and correct them in time. In the process of students' daily oral and written calculation, both pre calculation and post calculation estimation have certain value. Through research, we can improve the quality of primary school mathematics teaching materials, improve teachers' teaching ability, help teachers consciously and purposefully control and improve their teaching behavior, optimize classroom teaching, and improve the efficiency and quality of mathematics teaching, Change students' learning style, improve students' learning quality, and initially form a set of teaching strategies and methods supported by modern ecation theory. 6、 Research process and methods (1) research process (1) in the early exploration stage (November 2013 - January 2014), strengthen theoretical study, carry out investigation and research, carry out preliminary exploration, formulate implementation plan, carry out subject demonstration and application. Mainly around the new curriculum concept and the theory of mathematical calculation teaching, organize and carry out learning, enrich the knowledge reserve of experimental teachers; Train the research teachers and master the research methods and processes. This paper investigates the current situation of students' computing ability, analyzes the reasons, studies the countermeasures, and formulates the project implementation plan, so as to prepare for the research 2) Research stage (February 2014 to April 2014). Select the appropriate sample of research objects, formulate specific and feasible phased research plan, orderly carry out activities and conct in-depth research. Teachers in the research group teach according to the implementation plan, carry out test evaluation and competition activities, and explore effective strategies to improve students' computing ability. At the same time, we should carry out teaching and research activities, discuss the classroom teaching mode, collect process data, and on this basis, summarize the stage experience around the subject research, and write monographs 3) In the summary stage (April 2014 to July 2014), the research is summarized and the results are displayed

2.

An epidemic upset the situation

on the enterprise side, there are layoffs, salary cuts, job transfers, telecommuting... On the enterprise side, there are rent, housing loans, car loans, credit cards, flowers...

just like the theory of evolution, in the long evolutionary process of nature, the lives that can survive are neither the strongest nor the most intelligent, It's the ones that are most adaptable to the changing environment

I interviewed several people in the workplace, and they always said, "if you have money, why don't you do it?" But at the same time, we are also distressed "I do net red, what to do?"

however, I asked some bosses if they support employees to have sidelines. Two of them are very strict and must be dismissed for engaging in sidelines, because they will not be willing to do the main business

after this epidemic, we will scoff at those bosses who are forbidden to engage in sideline business. They can't pay their wages in full. Are we not allowed to engage in sideline business? Plan B

The hot topic of sideline demand and the rise of "odd jobs economy" have aroused people's deep thinking about the future economy. Now, whether office workers, housewives, ordinary people, stars, white-collar workers or senior executives of the company are also strongly aware that it is necessary to develop a sideline business outside the main business. Choosing procts, services, consulting, speaking, coaching and so on can bring an extra income

in fact, the sideline business is not so simple. A wechat business selling things in the circle of wechat friends has to work hard to fully support itself. There is no doubt about entrepreneurship. In my opinion, there are several ways to plan B

1. Income is not only guaranteed, but also the guarantee coefficient should be concerned. In the face of disaster, everyone is poor. Spiritual and material poverty

in the workplace, eight Cheng has debts but no savings. If you can take seven days off, you can have a good time, but if you have 30 days free, you will feel endless anxiety and worry. However, bank loans and credit card repayments still arrive on time every month. As an office worker, the absolute value of every month's salary is no longer a function of security. Having a plan B can also give yourself more security in the event of force majeure. The two plans increase the security factor

I have a friend who started a business at the end of the year and started a small restaurant. Half a year's rent had just been paid, but before it opened, it caught up with the epidemic. He suffered a great blow to the catering instry. Three days later, the reaction came back. It hit the catering too hard. Isn't it hot? He began to live to do simple cooking, because it was delicious and good-looking, so that many netizens at home, big brush traffic, a reward to fill the rent. In the limelight, he also promoted his business philosophy, and the twists and turns of the shop and the prevention of various pits began to be tiktok. He continued to bring her team with him for several days, opened Xiaohong book, jigsaw live broadcast, and so on, and worked with multiple platforms to expand the influence of his own physical store. p> Therefore, sideline is not an income, but a width of life. To broaden this width, you must first reach a certain height in your own skill field

Personal brand is beautiful, but how can it become a household name without hard work

it is the dream of everyone in the workplace to realize passive income and early wealth freedom. Why do you want to be a personal brand? A lot of people also buy on behalf of others, and many people also go to swipe orders. However, there are more than 200 people in the circle of wechat friends. How many copies can they sell

The most direct way to engage in sideline business is to realize one's interests and hobbies. And you also like this sideline from the bottom of your heart. When you focus on it, your personal brand will be built unconsciously

some people are proficient in photography and help others take photos outside of work, graally forming public praise; Some people do well in writing, and often contribute to the major we media, which not only earn contributions, but also improve their popularity; Some people like to lose weight, become models for some Taobao online stores, and become coaches in some gyms... In this era, we need to actively build personal brand, community operation, circle of friends marketing, release, drainage and promotion of content platform, etc

your popularity is the thickness of your income

all kinds of phenomena show that the most powerful way to distinguish yourself from competitors is to take risks and work hard like starting a business, and to create new opportunities in countless repetitions and boredom. Maybe one day you will find that the colleagues who are working with you tiktok 9 to 5 will use the time of playing games, chasing drama and shaking the voice to do sideline business, and you will not know how many times the monthly income is. p>

4. The goal is to increase income and optimize the income structure.

many people look down on those who brush orders and advertisements. However, what can be looked down upon when making money legally. To earn money out of work is the foundation of your life

however, only for this purpose can only increase the income, and can not change the income structure. Once there is an emergency, it is also in trouble. The main idea is from "after tax income" to "after sleep income"

such as investment income, financial management income, deposit interest income, equity dividend income, etc. This part of income is non working income, that is, income that can be obtained by sleeping, which can be called "income after sleeping"

and the era of knowledge payment is coming, and you can make money by your knowledge. Knowledge mainly depends on content, including writing, photography, music, painting, small video and so on. If you work hard in these aspects, you can also have a certain "after tax income". If we can publish works and obtain right income, it will be more powerful, including music, books, etc. The most difficult thing is to invent and register patents. At the same time, the transfer of patents, including machinery, electronics, communications and so on, has intellectual property rights. As long as you pay a one-time labor to make things, you can permanently charge fees and realize income after many times of sleep

sidelines are like entrepreneurship. Income has its business model

no matter what you do, the best business model now needs three elements: rigid demand, pain point and high frequency the selected sideline should be the just need of modern life as far as possible. If there is a demand, there will be a market. Only by solving the demand can we gain wealth
