Abstract
To better understand the sustainable development of open educational resources (OER), this paper aimed to break through the original ‘fixed’, highly structured evaluation system and develop an open and flexible “1 + X” evaluation framework of OER by using the modified Delphi method. “1” refers to the mandatory basic criteria that the repository must reflect essential attributes and core functions, which are consist of four components: information content, learning process, system technology, and user experience. “X” refers to optional distinctive criteria that the repository shall focus on one or more developmental orientations, which may include: resource evolution, international collaboration, inclusiveness and equality, open educational practices, and value-added services. Optional “X” criteria, in line with the criteria’s diversity aims, can lead to the sustainable development of OER and globalized lifelong learning. The framework of this study provides a basis for the evaluation and optimization of existing OER repositories, and also serves as functional scaffolding for the construction of new repositories.

Appendix 1 Evaluation Framework of OER (Delphi Round 1)
To better understand the sustainable development of open educational resources (OER), this study aimed to break through the original ‘fixed’, highly structured evaluation system and develop an open and flexible “1 + X” evaluation framework of OER. “1” refers to the mandatory basic criteria that the repository must reflect essential attributes and core functions. “X” refers to optional distinctive criteria that the repository focuses on distinctive and diversified developmental orientations.

The revised preliminary proposal of the criteria “1” is showed in table according the result of Delphi Round 1. The main optimizations were: (i) excluding or further integrating the indicators of ‘Coaching’ and ‘Navigation Design’ with a mean value below 3.5 and CV ≥ 0.25, (ii) integrating ‘Instructional Design’, which is of general concern to experts in the interviews, into the ‘Learning Process’ dimension of the basic indicators, and merging the existing secondary criteria of ‘Learning Activities’, and (iii) adding ‘User Guide’ and ‘Ease of Use’ criteria. Please rate the indicators based on your experience. (from “not at all important” to “extremely important”, value 1 to 5)
