What are the disadvantages of traditional classroom teaching?

First, each subject has its own logical order and scientific system, and the subject knowledge of each sub-subject course is relatively closed, which can not reflect the unity of the objective world itself and the organic integrity of mutual connection, so it is difficult for students to form a complete picture and a preliminary scientific world outlook on cognitive objects.

Second, the curriculum is too detailed and divorced from the characteristics of children's psychological development.

Third, there are many kinds of subject teaching courses, and the phenomenon of overlapping and repetition is serious, resulting in a waste of time and spirit. In this way, it will inevitably increase the academic burden of students, affect their physical and mental development, and is not conducive to the improvement of students' quality.

Fourthly, the curriculum structure of subject-based teaching is unreasonable. Some subjects are unilaterally emphasized, while others are in name only. Students' cultivation, creativity and operation abilities are ignored, and interdisciplinary knowledge and methods are not available, which affects the improvement of education quality.
