▲ teachers of Taizhou Wenyuan primary school use high-quality homework system to comment on homework in class. Information picture ▲ in the high-quality operation system, the class accuracy grade distribution display page of each chapter. Information picture In July, 2021, the central office and the State Council Office issued the opinions on further reducing the burden of homework and after-school training at the stage of compulsory education (hereinafter referred to as the opinions), proposing to "comprehensively reduce the total amount and duration of homework and reduce students' excessive homework burden". What is the value and significance of homework? The requirement behind the "reduction and quality improvement" of the operation is "accuracy". How to achieve the accuracy of the operation scene? What changes will be brought to the operation when AI (Artificial Intelligence), algorithm and other technical means enter the operation scene? A series of questions need to be answered by the competent departments, schools, teachers, parents and even all sectors of society; A more profound digital revolution is also upgrading the reform of new enabling education. Educational informationization has become the "commanding height" of development Since the 18th National Congress of the Communist Party of China, China's informatization construction has made a brilliant report step by step from top-level design and policy deployment to infrastructure, digital resources, platform construction and application exploration. In the past decade, China's educational informatization has entered the integration and innovation stage from the initial application stage. At the national level, the policy system for promoting the development of education informatization is becoming more and more perfect, which has laid a solid foundation for further supporting the large-scale application of information technology and helping the reform and development of education. Among them, the implementation of the education informatization 2.0 action plan echoes the profound changes in talent demand and education patterns caused by artificial intelligence, big data, blockchain and other technologies, and defines that by 2022, the development goal of "three complete, two high and one large" will be basically achieved, that is, teaching applications will cover all teachers, learning applications will cover all school-age students, digital campus construction will cover all schools, and the informatization application level and information literacy of teachers and students will be generally improved, Build a "Internet + education" platform. At the local level, Beijing recently issued the "fourteenth five year plan" for Beijing's educational informatization. By 2025, Beijing's educational informatization will achieve the "seven comprehensive" development goals. Through science and technology enabled education, we will promote the reform of talent training mode, improve the quality of education, help reduce the burden and increase efficiency, and promote educational equity. Up to now, Beijing, Shanghai, Guangzhou, Zhejiang, Jiangsu and other places have issued the "fourteenth five year plan" for educational informatization or the educational digital transformation plan. The "fourteenth five year plan" for education in Henan, Shandong, Guangdong and other places has also set up a special chapter on education informatization. The application and construction of educational information technology needs more external forces. During the 13th Five Year Plan period, hardware and network platforms represented by computer classrooms, campus networks and campus security accounted for a considerable proportion of the investment in education informatization. The National Informatization Plan for the 14th five year plan proposes to improve the national public service system for digital education resources, promote educational and teaching reform integrating information technology, intelligent technology and education and teaching, and deepen the analysis and application of big data in the field of education. To this end, Beijing has proposed to support schools to reduce the cost of information technology investment, avoid repeated construction, explore multiple investment mechanisms, guide social enterprises to participate in education information construction, achieve win-win results and stimulate market vitality by reusing municipal and district level common applications or purchasing social services; Guangzhou proposed to encourage enterprises and social forces to increase investment and participate in the construction and service of educational informatization; Tianjin proposed to actively encourage enterprises to invest in providing high-quality information-based products and services. Precision has become the "bull nose" of high-quality education In terms of improving the quality of homework design, the opinions requires that the functions of homework diagnosis, consolidation and learning situation analysis should be brought into play, and homework design should be incorporated into the teaching and research system. The system design should conform to the age characteristics and learning rules, and reflect the basic homework oriented by quality education. Encourage the arrangement of layered, flexible and personalized operations, resolutely overcome mechanical and invalid operations, and put an end to repetitive and punitive operations. In terms of strengthening the guidance on homework completion, the opinions requires teachers to guide primary school students to basically complete their written homework in the school, and junior high school students to complete most of their written homework in the school. Teachers should carefully correct their homework, give feedback in time, strengthen face-to-face explanation, carefully analyze the learning situation, and do a good job in Q & a guidance. Students are not allowed to approve and correct their homework by themselves. "High quality homework is an important way to achieve high-quality education and an inevitable requirement for the overall improvement of education. Through high-quality homework, students can effectively consolidate what they have learned, improve their learning ability, improve their learning efficiency, and reduce the heavy burden of schoolwork; through high-quality work, teachers can accurately grasp students' learning status, enhance the pertinence and effectiveness of teaching, improve the efficiency of teaching, and accurately and quantitatively analyze teaching results Lose, improve teaching and improve the overall teaching quality. " Wuxi Guangqin middle school principal Ye Hao said with deep feeling. Yehao said frankly, "At present, the assignments we need are, first, those that conform to the curriculum standards and are conducive to students' creative learning and ability improvement, rather than rote and mechanical repetition; second, those that are accurate and effective and help students improve their learning efficiency on an individual basis, rather than stereotyped and lack of targeted assignments; third, those that can be fed back in time and help students' differentiation, reinforcement and improvement, rather than general and superficial learning assignments." The "double reduction" policy puts forward requirements for homework, such as recording homework time, designing homework, timely correcting feedback, analyzing learning situation, arranging personalized homework, and grading homework... The essence of these requirements is accuracy. How to make the operation scene accurate? In this regard, Zou Jing, the person in charge of high-quality operation products of cloud intelligence, said that good operation does not win by quantity, but by accurate adaptation. "After the application practice in last fall semester and this spring semester, hundreds of schools across the country have started to use our high-quality homework solutions, such as Beijing Guangqumen middle school, Wuxi Guangqin middle school, Taizhou Wenyuan primary school, etc. at present, from homework design to data collection and analysis, they have helped schools provide some valuable teaching references." Zou Jing disclosed. Based on the cloud intelligence high-quality operation platform, Taizhou Wenyuan primary school focuses on the collection, evaluation, feedback and improvement of normalized operation data, carries out the whole process evaluation of operation quality, improves the quality of operation design and classroom teaching efficiency. Taking the third grade mathematics as an example, each teacher of Wenyuan primary school collects 36 homework data on average every month, which is equivalent to the collection and accumulation of students' learning situation data every day. Daily high-frequency data accumulation ensures the data presentation of students' mastery of each knowledge point in each chapter. For example, in unit 2, the excellent rate of the fourth class "division with 0 in the middle of quotient" is lower than that of the seventh class "flexible selection of estimation strategies to solve problems". Teachers have increased class review and explanation of key and difficult points for this class to strengthen students' understanding and mastery of this knowledge point. AI technology provides support for educational informatization In the view of industry experts, cloud intelligence high-quality homework is essentially a personalized learning solution based on massive resources, big data and artificial intelligence, facing a variety of homework scenarios and adapting to different student groups. Starting from homework, it not only holds the "bull's nose" of high-quality education, but also holds the "entrance" of digital transformation of education, realizing the whole chain connection before, during and after class, as well as the multi-dimensional evaluation of teachers and students. "We have a massive question bank of 540million", said the head of high-quality homework research and development of cloud intelligence. It is the massive high-quality question bank that supports high-quality homework. At the same time, the AI system can accurately push the most suitable topics and resources for each student through search, recommendation, natural language processing and other technologies. In the link of data collection and correction, OCR, image recognition and other technologies liberate teachers from the heavy repetitive work, and put more energy into the precise teaching of homework and personalized guidance. The head of research and development of intelligent technology assisted correction of cloud intelligence disclosed that in terms of processing capacity, the AI system of cloud intelligence can correct 100000 jobs per minute. The reporter learned that since September 2021, Wuxi Guangqin middle school has been cooperating with cloud intelligence. With the help of the "cloud intelligence high quality operating system", the whole process of homework has been digitized through the big data learning situation analysis system, AI technology, massive high-quality question bank resources and information-based intelligent terminals, with the normal use of schools and teachers as the baseline and the goal of reducing the quantity and improving the quality of homework, The traditional learning consolidation mode of homework has taken on a new look in Guangqin middle school. It not only helps teachers and school administrators to carry out homework evaluation, optimize homework management, improve teaching research and teaching, and achieve accurate classroom evaluation, but also helps students to achieve personalized and accurate practice by drawing inferences from one instance. It has played a positive role in improving the quality of school education. In fact, in addition to helping teachers with accurate teaching, the cloud intelligence high-quality operating system can also help school administrators achieve efficient management. Through the data Kanban, managers can master the school situation, teachers' teaching situation and students' learning situation in real time, and visually display the homework situation in multiple dimensions, helping to achieve efficient, accurate and intelligent teaching management and homework management. "In the context of reducing the burden, this system has achieved good application results in schools. We look forward to more grades and disciplines participating in the follow-up to help our teachers and students reduce the burden and increase efficiency." Yehao pointed out that to achieve high-quality education, it is necessary to improve the application level of school informatization, improve the informatization application ability of teachers and students, and deeply integrate information technology and intelligent technology into the whole process of education, which is an effective way to achieve high-quality education in the information society.
