Recently, the general office of the Ministry of Education issued a notice, which put forward clear requirements for strengthening education app management and promoting the connection with the "double reduction" policy. The notice proposes that the homework app that provides and disseminates "photo search questions" and other bad learning methods that lazy students' thinking ability, affect students' independent thinking and violate the laws of education and teaching will be temporarily offline. The record can be restored only after the rectification is in place and reviewed by the provincial education administrative department; If it fails to pass the examination, the record shall be revoked. The answer comes as soon as the mobile phone hits. What is the operation experience of such a "magical" photo search app? What are the opinions of parents, students and teachers on temporarily offline such products? How should we view and use this kind of technology? The reporter conducted an investigation. "The homework was well done, but it was revealed as soon as the exam came." The photo search app, first launched by online educational institutions, was once popular among students. At the gate of many schools in Haidian, Beijing, the reporter interviewed a number of primary and secondary school students. They all used such products to help complete their homework. Liu Lu, a junior high school student, told reporters: "some knowledge points look very simple, but they don't master them and don't dare to ask the teacher." She usually uses the photo search app to search for math questions, "some questions, and video analysis below". Wang Han, the principal of a primary school in Jinan, first heard that the photo search app was at an on campus meeting. She listened to the teachers talk, there are always a few students in the class, "the homework is well done, but it will show up as soon as the exam comes". After Wang Han's investigation, he found the "fishy" behind it. Many parents are busy working and neglect to care about their children's studies, while children use photos to search questions app to "do their homework without thinking". "As like as two peas," not only can we directly search out the correct answers to mathematical questions, but also the same process. Du Jiping, a math teacher in the school, saw "identical homework" several times. He believes that this is "no difference" from copying homework. "Some students think they can understand the answers after reading them, even if they learn them. But in fact, being able to understand the answers is completely different from doing it independently". The reporter's investigation found that not only science homework such as mathematics, chemistry and physics, but also "plagiarism traces" will appear in some Chinese homework. "When you look at some words and sentences in students' homework, you are sure that a fifth grader can't write them." A primary school Chinese teacher said. As the headmaster, after understanding these situations, Wang Han immediately "took measures": asked each class to strengthen home school contact and inform parents of the harm of using photo search app; Try to let students finish most of their homework independently in school; Teachers are required to assign more open questions focusing on the answer process. Some "parental mode" settings are useless In 2013, the photo search app appeared for the first time, and then several online counseling platforms launched similar products, and some head brands received multiple rounds of investment. After the enthusiasm of capital has receded, there are only a few well-known photo search apps left on the track. What is the operating experience of such products? Recently, the reporter found in the mobile app store that there are still multiple photo search apps available for download. After downloading and entering an app, it is found that there are no keywords such as "taking photos" or "search questions" on its home page. Instead, there are words such as "video Q & a" and "search Q & a". After clicking to enter, you can still use the photo search function. At present, most of the photo search App has provided the function of "student and parent / teacher mode switching". The reporter randomly searched the question under the "student mode". The result showed that "the parents can complete the analysis after they have been certified successfully", but "parents certification" only requires the name and ID number of any adult, and no need for face recognition and other operations. Some apps can switch to "parent mode" by binding wechat applet. Parents can master their children's learning through visual chemical situation reports such as daily, weekly, semester reports and real-time error books. However, there are also some "parent mode" of photo search app, which is cumbersome and complex and difficult to operate. In the South Gate of China Agricultural University, the reporter met Niu Guixing, a takeout worker. "Due to the limited educational level and the fact that he usually goes out early and returns late, it's hard to take care of the homework of the boss and the second child". He said "love and hate" about the photo search app. A few days ago, Niu Guixing and his wife worked with their mobile phone for a long time. "They didn't learn how to switch to parent mode. I can't understand the child's homework, so let him check it with his mobile phone.". In the face of photo search app, the attitude is different from that of school teachers, but some parents hesitate. For Wu Li, a parent in Haidian, Beijing, the photo search app is a "good helper" to guide children's learning: "children's science scores are very good. If they encounter problems occasionally, they will search the app for answers and analysis." Wu Li supervised the children. After video explanation, digestion and absorption, combined with relevant knowledge points, she found the same type of questions to practice and consolidate, "the children are very conscious and active in learning". In March 2020, after the emergence of the photo search app for real person online Q & A, it was popular with parents and students and became a new form of online teaching. "What about tutoring children if they go offline?" Wu Li asked. One size fits all, depending on the situation Taking full account of the particularity of online teaching and home-based learning, we can't take photos and search questions all at once. However, if the original one-to-one counseling is directly moved to the photo search app and the counseling time is divided into parts, it is obviously contrary to the requirements of the "double reduction" policy. Luo Zhimin, a professor at Zhengzhou University, suggested that specific restrictions should be made on the time period, total time and the latest learning time of online learning of photo search app according to the requirements of different grades. "To keep students away from photo search app dependence, the key is to keep up with teacher guidance". After the emergence of the Internet, all kinds of new technologies emerge in endlessly. Whether they help students learn or affect students' independent thinking, it is always difficult to find a clear answer. Obviously, the photo search app will not be the last one to encounter this problem. "Information technology has gone deep into the society, and education really needs to make full use of information technology, but education should make differences in the use of information technology in different segments. This notice makes it clear that the application for filing of preschool online training app will no longer be accepted, and the registered relevant app will be revoked, which further explains this point." Professor Luo zubing of central China Normal University suggested that teachers or parents use information technology to serve students' learning instead of allowing lower grade students to use it as far as possible; Middle and senior primary school students should use it under the guidance and supervision of parents and teachers; In junior and senior high schools, although students can use information technology independently, they should use it as little as possible on the whole.
