The present invention provides an online course forum interaction pattern recognition method and system, comprising: obtaining long-term data and short-term data of students' posts, replies, comments, teachers' posts, replies, and posts in the online course forum; according to the online course forum, students The number of posts and the time interval of posting screen out active students in the forum; based on the short-term data of each active student screened out, according to the number of posts, replies, or number of posts in the time granularity corresponding to each course At least one is clustered; according to whether there are short-term data of active students clustered successfully, the proportion of active students with successful clustering to the total active students, and whether the short-term data of students’ posting volume and the short-term data of teacher’s posting volume are on the time curve Coincidence divides the interaction modes of online course forums into task-based forums, autonomous forums, guided forums, or free-form forums. The invention can help teaching and research personnel quickly identify and analyze a certain forum.
Description
technical field [0001] The invention belongs to the technical field of online course analysis, and more particularly relates to a method and system for identifying an interactive pattern of an online course forum. Background technique [0002] Online courses have become an important part of student education, and are an important way to strengthen students' self-learning ability and reduce the burden on teachers. Course forums are an important channel for teacher-student interaction in online open courses. The teacher's interaction ideas are related to its design. Therefore, the number of different forums and the number of posts are different. For example, the teacher assigns several interactive assignments, and the teacher requires certain groups To start a discussion, the teacher asks the students to start a discussion and play freely and so on. It is difficult to know the teacher's teaching design just by looking at the number or quantity of posts. Relevant measurement ...
