Abstract

The invention provides a classroom cognitive load detection system, which belongs to the field of educational informatization. Including: task completion feature collection module, used to record students' response time and answer accuracy rate when completing tasks; cognitive load self-evaluation measurement collection module, used to quantify and analyze students' psychological effort and task subjective difficulty; The facial expression and attention feature collection module is used to collect students’ classroom performance videos, and counts the students’ smile and gaze duration according to the video analysis results; the feature fusion module is used to fuse the above six indicators into feature vectors; the cognitive load determination module, Used to feed feature vectors into a classifier to identify students' classroom cognitive load levels. The application of the invention can objectively, quickly and accurately rate the cognitive load of students in the classroom, help teachers improve the organization and presentation of learning materials, reduce the external cognitive load caused thereby, and improve teaching effect.

Description

technical field [0001] The invention belongs to the technical field of education informationization, and in particular relates to a classroom teaching cognitive load measurement system. Background technique [0002] Cognitive load is the total amount of information that needs to be processed in working memory. Working memory, also known as short-term memory, is mainly responsible for acquiring and temporarily storing information in the current situation, and gaining an overall understanding of the task by associating it with information in long-term memory. Since the capacity of working memory is limited, when the target information in the learning environment is too rich or presented in an improper way, it will easily lead to overloading of the learner's working memory capacity and affect the learner's cognitive processing. The application of cognitive load theory in teaching is to reduce the external cognitive load caused by the organization and presentation of learning m...
