Nearly two months after school, Mo Mo, a parent in Shanghai, still feels "a little incredible": his third grade children "don't have any homework" after school every day. "It is said that they have finished it in school. They don't have to stare at their homework when they get home. The relationship is particularly harmonious". "What parents meet and ask most now is, has your school reduced? Do you have homework?" Mo Mo said. Less or no homework, extending after-school service time; Spend more time with children and have harmonious family relations... This is the feeling of many parents after the "double reduction". As the main body of implementing the "double reduction" policy, the school has taken many measures to ensure that the "double reduction" effectively solves the concerns of parents and students and makes "education return to the main position of the school". To "reduce the burden" in the school, students and parents are most concerned about whether the "amount of homework" is reduced and whether the classroom efficiency is improved. Therefore, the primary school affiliated to Hefei Normal University actively carries out the reform of homework and evaluation. From top to bottom, the school formulates the system and requirements for homework assignment and correction. The school carries out the research of expert guidance and peer assistance, and invites teaching and research staff to provide teachers with disciplinary training to grasp the homework design strategies of different knowledge blocks in different years; Through collective lesson preparation, work out the operation plan of each lesson with the teaching and research group, which can not only shorten the operation time, but also improve the operation quality. Intelligent technical means are also helping to implement the "double reduction". According to Sun Zhigang, vice president of Fengxian Senior High School in Jiangsu Province, the call for "double reduction" is not a "one size fits all" cut in half, but to ask for quality from the classroom and efficiency from learning. Sun Zhigang believes that using big data + artificial intelligence to create accurate teaching, "with the help of smart classroom, it can not only promote 'double reduction', but also realize 'double addition'." Through the smart classroom platform, we have realized the organic integration before, during and after class, created a teaching mode combining online and offline, and realized the maximum sharing of resources. "Let students learn more actively and make full use of 45 minutes in the classroom". Sun Zhigang believes that this is the "improvement" of teaching. At the same time, according to the big data precision teaching system, data feedback is formed by recording the wrong questions in students' daily practice and examination, so that the key points and blind areas are clear at a glance. Teachers can be targeted and explain typical errors in layers; For each student's different difficulties, the personalized learning manual of smart classroom analyzes students' abilities in various disciplines from multiple dimensions, pushes learning resources for them, improves directional error correction, carries out variant exercises, draws inferences from one instance, and makes the mastery of knowledge points more reliable. "With the focus of breakthrough, students certainly don't need 'sea tactics', which is the' efficiency 'of learning," Sun Zhigang said. In addition to the reduction of homework, another change brought about by the "double reduction" policy is the enrichment and diversity of after-school services in order to effectively reduce the burden of students' homework and after-school training. Xinqi middle school in Beilun District of Ningbo City launched after-school delay service in Grade 7 and evening self-study in grade 89. School principal Le Nahong introduced that after-school services are managed by teachers of Chinese, mathematics, English, science and Social Sciences, focusing on completing homework and not taking new courses. If you encounter difficulties in completing your homework, the teacher can answer questions. And the school will prepare afternoon snacks for students participating in after-school services every day and provide dinner for students participating in evening self-study. In Changjiang Middle School in Beilun District, the forms of after-school service are more abundant. One is the basic type, which mainly carries out students' homework guidance after school. The teachers of language, mathematics, English, science and society in the class will enter the class for management, and arrange students to do homework, independent reading and other projects. The second is characteristic type, which carries out various characteristic training activities. In combination with its school running characteristics, the university carries out sports, art and other associations to develop students' interests and specialties, and focuses on cultivating students' various skills to help students develop in an all-round way. What is the efficiency of students' homework after class service? At more than 6 p.m., after a day's study, Liu Han in class 802 of Chunxiao experimental school in Beilun District felt relaxed. Liu Han was a little inefficient when he used to do his homework at home. However, after two hours of self-study at school, he not only completed the homework of the day, but also set aside time to preview the text of the next day. Police officer Xue, parents of Minshan school in Beilun District, also felt deeply. Because of the nature of his work, he has to be on duty every week. Picking up children has always been a headache for the couple. "With after-school service, children can finish most of their homework with high quality in the school, and we don't have to delay our work in order to pick up the children's leave. This year, er Bao also enrolled in Minshan school. I applied for the late pick-up service for ER Bao, so that the two children can go to school at the same time," said police officer Xue. Mr. Shao of Minshan school has been involved in after-school service for four years. "It's my turn twice a week, and the workload has indeed increased. However, as an educator, my extended service can make so many children's parents in the class work at ease, and also make the children's homework basically completed in school. I can also give face-to-face guidance to individual children with weak foundation, so as to clear their homework every day. I have implemented the goal of reducing the burden without reducing the quality of the" double reduction "policy. It's true It's worth it. " (outlook new era)
