First of all, books must be genuine, and secondly, the cost of books is actually very low, but in the past, the cost of physical bookstores was higher, so in people's impression, books are genuine only when they are expensive. Now, the emergence of online stores such as Taobao has reduced the cost, which gives people the impression that books are very cheap.

the influence of science and technology on learning style

(1) Renewing the teaching concept, giving full play to the role of modern information technology in classroom teaching, changing the traditional teaching mode and learning mode, realizing the changes in the presentation mode of teaching content, teaching mode and interaction mode between teachers and students, optimizing classroom teaching and promoting students' all-round development is another important work we have done.

(2) With the support of information technology, students' learning is no longer limited to the classroom, but extends to anytime and anywhere. In teaching, teachers will make some important and difficult points into exquisite and practical micro-lessons. Then, these high-quality resources will be shared in the network and QQ group, and children can adjust their learning progress at any time according to their own learning situation, thus realizing one-on-one teaching on the network.

Disadvantages of second-line learning

(1) The role of teachers has become a simple "network anchor". Because most teachers are in contact with online teaching for the first time, the use of the platform is in the exploratory stage, and the role of teachers has become a simple "anchor". In many cases, teachers are talking alone, students are listening, and there is no interaction between teachers and students in on-site teaching.

(2) Lack of effective control over students. Because there is no on-site teaching, teachers can't restrain students. If students' self-discipline ability is poor, they don't concentrate when listening to lectures, and they play games, listen to music, read novels, send messages, or even leave the classroom halfway, they can't stop it in time. Such teaching effect is doomed to be poor.
