迭代共生:开放课程资源建设的路径创新

Iterative Symbiosis ： A New Path for the Construction of Open Course Resources

近些年我国开放课程的迅速发展对促进国内优质教育资源共享产生深远影响，但在开放课程资 源开发的持久性和再生性发展中遇到一些共性问题。南京师范大学“视觉文化与媒介素养”课程在长期的课程 建设实践中探索形成的“从共享到共生”的资源开发模式可以为这些共性问题的解决提供有益的借鉴，如果在 “从共享到共生”的基础上再进一步提升为可持续的“迭代共生”资源开发模式，将不失为突破我国开放课程资 源建设瓶劲问题之有效创新路径。

In recent years， the rapid development of open courses has a profound impact on the sharing of domestic high -quality education resources. However， the development of open courses resources has encountered mutual problems in respect of sustainability and reproducibility， such as ＂ high dropout rate＂ and ＂ low sustained rate＂ ， ＂ low update rate＂ and ＂ narrow range of options ＂. The core of the problems lie in the fact that the one way development makes open courses unable to grow healthily. Under this background， the urgent issue is how to maintain the sustainability of open courses. In order to make a breakthrough， the author made an empirical research into the mode of resources development ＂From Sharing to Symbiosis ＂ on the basis of ＂ Visual Culture and Media Literacy＂ course which has been constructed and explored for over a decade in Nanjing Normal University. By theoretically combing and extracting the data， this study proposes a new path to open courses resources development ＂ Iterative Symbiosis ＂ and expects to achieve a sustainable development of open courses resources. The ＂ From Sharing to Symbiosis＂ model has innovatively subverted the traditional one - way resources development model and has incorporated the students' works into the creation of a new round of teaching resources development. Students who select the course have double identities in that they both share the original resources and create renewable resources. Simultaneously， with the continued expansion of the developers， learning resources keep expanding and optimizing. This resources development model has achieved sustainable development of courses resources.
