The experimental project of X-ray crystal diffraction was taken as an example to build the educationresouree database of universe physics experimental course. Using QR code technology,the education resourcedatabase , consisting of experimental principles, content , ideological and political elements, and instrumentusages , has been established to the cloud. Under the condition of mobile intemmet, sudents can easily use themobile WeChat and Alipay scanning function to browse the database in the preview,experimental operation andafter class stages , which promotes active leaming.The results of anonymous survey question naires indicate that the constructed database has been approved by the majority of students ,and is strongly recommended to other courses.
