Hello Yaqi,

I really like your post this week. I think you did a great job in introducing OER. I agree with your opinion about the advantage of OER. By providing free or affordable online materials, learners foom deprived backgrounds can also have opportunities to learners. But, learners still need electronic devices such as mobile phone to read the OER. For learners who cannot afford electronic devices, it is still difficult for them to access the learning materials although they can use the computer in public libraries.

Sincerely,

Ruoxi
