According to the official website of the Ministry of education, recently, the Ministry of Education issued a notice to make it clear that homework apps that lazy students' thinking ability, affect students' independent thinking and violate the laws of education and teaching, such as "taking photos and searching questions", will be temporarily offline. The record can be restored only after the rectification is in place and reviewed by the provincial education administrative department. In July this year, the central office and the State Council Office issued documents to make it clear that online training institutions shall not provide and disseminate bad learning methods that lazy students' thinking ability, affect students' independent thinking and violate the laws of education and teaching, such as "taking photos and searching questions". The notice of the Ministry of education is implementing the "double reduction" provisions. The "photo search question" homework app has been controversial since it was launched. Developers and operators believe that the "photo search" app is like a teacher or a classmate with excellent results, which is convenient for students to consult and get ideas for problem solving. The skeptics believe that this is not only inconvenient for students to learn independently, but also convenient for students to be lazy and get answers directly through the app. Many students download this kind of APP in order to quickly complete their homework and copy the answers. Cultivating students' autonomous learning and management is not easy, and the existence of "photo search questions" app is stimulating students' dependence. Therefore, many parents call for the cancellation of such apps to create a good environment for cultivating students' autonomous learning habits and abilities. This time, the "photo search question" homework app is temporarily offline. It is not that all homework apps are not allowed to exist, but to seek advantages and avoid disadvantages and limit the disadvantages of homework app. Homework app makes use of artificial intelligence technology and big data technology. It still has its advantages in arranging personalized homework, flexible homework and feeding back students' homework efficiency. However, "Ai + education" must respect the law of education and cannot stimulate exam anxiety. This notice makes it clear that the application for filing of preschool online training app will not be accepted, and the filed related apps will be revoked. This is even more evident. It is worth noting that after the "double reduction" governance of "photo search" apps, some education and training institutions turned to developing "physical products" with similar functions, and "productized" the online training content and app, which is known as so and so smart learning machine, and sold it to students and parents, and the product function is similar to that of previous apps. In this regard, it is necessary to bring such products into unified and standardized governance to prevent institutions from playing a marginal ball. (Xinhua News Agency)
