The Piazza Q&A platform and the Open edX platform are independent of each other, which is inconvenient for users to utilize the platform data efficiently. In response to the above issue, this paper persists in storing Piazza Q&A data, uses the multi-tag filtering method to improve the searching ability of the Piazza Q&A data, uses the Piazza-Xblock plug-in to find and display the Piazza Q&A data on the Open edX platform, and uses URL parameters to directly access the Piazza specific pages, thus achieving the effect of intergrating the Piazza Q&A platform and Open edX platform.
