1. Low learning efficiency

In the natural environment, students' cognition of their own learning activities is chaotic. What knowledge they have mastered and what knowledge they have not mastered, how much to learn every day is appropriate, when to review is the most effective, and how to learn only what they have not mastered is vague and inaccurate. Therefore, in the process of learning, we often spend time learning what we have mastered, and we can't review what we haven't learned in time. A lot of time is spent on repetitive learning, which is ineffective or inefficient, resulting in low learning efficiency.

2. Students' schoolwork burden is too heavy.

Under the current education system in China, the academic pressure of primary and secondary school students in China is too great. On average, there are no less than 6 classes every day from Monday to Friday, and there are basically no weekends in grade three and grade three. In addition, there are a lot of exams and homework, which gives people the impression that students in China generally have endless classes, exams and homework, resulting in excessive academic burden. The Comparative Research Report on Learning Consciousness and State of Senior High School Students in China, Japan, Korea and the United States released by China Youth Research Center shows that China students have the longest learning time, the most active classroom learning behavior and the least bad learning behavior, but the lowest satisfaction with their grades. At the same time, the 2009 Follow-up Survey of Chinese Families published by China Social Science Investigation Center of Peking University conducted a follow-up survey of 1995 families in Beijing, Shanghai and Guangdong. According to the survey, the average daily study time of students in the three places is 12 hours, with Beijing students having the longest study time of 12.7 hours.

3. The teacher is under too much pressure

Under the current national conditions and the current education system, teachers are under too much pressure because of the pressure of entering a higher school and the expectations of parents; Heavy teaching tasks, a lot of preparing lessons, preparing for exams, correcting homework, tutoring students and implementing quality education have also caused many teachers' physical and mental fatigue.

4. The learning process cannot be monitored.

Under the existing learning and teaching environment, teachers, students, schools and parents cannot monitor learning and teaching activities simultaneously. Students' learning activities in and out of class can only be evaluated through classroom tests, mid-term and final exams. However, this assessment has three main shortcomings. First, the exam can't cover all the knowledge points that students need to master; Secondly, due to the lag of evaluation, it can not provide immediate guidance for students' learning activities; Third, it is impossible to know exactly what knowledge points each student has mastered and which knowledge points have not yet been mastered.

5. The learning effect cannot be guaranteed

Under the existing learning and teaching environment, classroom teaching can't guarantee the learning effect. For thousands of years, education has basically been "the master leads the door and the practice is in the individual". A basic premise of the existing educational model is that teachers can only guarantee "teaching" but not "learning". No matter how good a teacher is, he can only make classroom teaching simple, fascinating and knowledgeable. Whether you can master all the knowledge you have learned and turn it into ability requires students to review a lot after class.
