Example Embodiment

[0055] In recent years, the development of artificial intelligence brings new motivation, especially intelligent learning and evaluation. On the one hand, under the support of smart education policy, the deployment of smart campus has begun to scale, and the development of intelligent hardware technology has also provided equipment foundation for the intelligentization of classroom teaching evaluation. On the other hand, artificial intelligence, big data and other technologies provide an algorithm foundation for the intelligence of classroom teaching. Therefore, the classroom teaching behavior is analyzed by means of intelligent technology, bringing more convenient and more objective results. About the related theoretical research of AI classroom teaching evaluation, there are currently more but more direction of engineering applications, while abroad is less. AI evaluation system is able to analyze classroom audio and video data, the results are more objective and reliable, able ...

Abstract

The invention provides a classroom teaching evaluation method based on a combined weighting method, and belongs to the technical field of intelligent education. The method comprises the following steps: acquiring sample teaching classroom data, and generating a first feature sequence; according to a preset index type, performing normalization processing on the first feature sequence to obtain a second feature sequence; according to the second feature sequence, using an analytic hierarchy process to calculate the subjective weight of each preset index, and using an entropy weight method to calculate the objective weight of each preset index, wherein the preset index is an output parameter of a preset classroom teaching evaluation model; combining the subjective weight and the objective weight of each preset index based on a preset optimization strategy to obtain a comprehensive weight of each preset index; obtaining classroom data of to-be-evaluated classroom teaching; and inputting the to-be-evaluated classroom data into the classroom teaching evaluation model to obtain an evaluation value of each index of the to-be-evaluated classroom teaching. Effective information in the subjective weight and the objective weight is considered, and the effectiveness and the reliability of the evaluation result are high.

Description

technical field [0001] The invention belongs to the technical field of wisdom education, and in particular relates to a classroom teaching evaluation method based on a combined weighting method. Background technique [0002] In teaching activities, objective and fair evaluation of classroom teaching is the main means to measure teachers' teaching level and students' classroom performance. [0003] In the early days, researchers were organized to go deep into the classroom by manpower. While observing the classroom, they conducted evaluation and analysis according to the traditional scale designed in advance. This approach requires a lot of time and human resources, and it cannot evaluate a large number of courses. Later, the emergence of audio and video technology enabled the evaluation of some courses to use video instead of classroom observation, and then still use manual methods to watch repeatedly for subsequent evaluation and analysis. Later, the development of comput...
