Analysis of Topic Quality and Student Characteristics in Online Discussion Board Based on S-P Table

Discussion, as an important part of online learning, has been widely used in teaching to support communication and information sharing among learners. However, there are some problems in online discussion, such as poor topic design, students' low discussion depth and enthusiasm. S-P table analysis was applied to online discussion analysis. Based on the 186 posting records of 35 students under 9 topics on Wolearn platform, the quality of the topics and the characteristics of students were analyzed from the aspects of full answer rate, warning coefficient, difference coefficient, stability coefficient and suitability coefficient. We found that the topic was stable and consistent with the instructional objectives and students' cognitive level. Most of the students' learning status was stable and they had a good understanding of the topic, but some students did not perform well. Finally, some suggestions for further research were proposed.
