Interest is the most important step in learning. If you are not interested, you need to help children cultivate their interest in learning through some methods. Iflytek learning machine's "personalized precision learning" system can do this well. This system is based on the massive data of Iflytek Intelligent Learning Product 15 years, and uses A.I. technology to accurately analyze students' weak knowledge points, so as to help students understand their knowledge structure scientifically and macroscopically. Red means bad mastery, and green means good mastery, so as to check and fill gaps and improve grades. Students who want to get such accurate analysis can get it by doing no more than 10 on the learning machine. The learning machine can also tell him what the best acquisition sequence is, and intelligently recommend the corresponding micro-lesson video explanation and practice. First learn the knowledge points to open your mind, and then practice doing the questions to deepen your impression. After repeated practice, the knowledge points will soon be mastered. More importantly, watching little red dot turn into a little green dot on his knowledge map will give him the pleasure of upgrading his study.
