In this embodiment, the learning difference refers to a situation of interest in a classroom of the same subject after comprehensive statistics is performed on each item in the multidimensional parameter list, so as to obtain the learning difference.
In this embodiment, for example, the learning bias of students 1, 2, 3, 4, 5, and 7 is teaching interaction, the learning bias of student 6 is not teaching interaction, and the learning bias of students 8 and 9 is neutral (both of them), at this time, the recommendation bias is determined by determining different occupation ratios, for example, the finally determined recommendation bias is teaching interaction.
The beneficial effects of the above technical scheme are: through establishing the multidimensional parameter list in the teaching interaction and non-teaching interaction (video recording) processes, the list in the teaching interaction process is analyzed based on the situations of stagnation, transition and the like in network delay, the interaction factors can be effectively adjusted, the accuracy of learning difference is improved, and finally, through determining deviation, effective recommendation is carried out, the teaching efficiency is improved more efficiently, and meanwhile, remote teaching can be realized based on a teacher end and a student end, and the teaching effect is improved.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
