Article analysis:

The article is generally reliable and trustworthy, as it provides a detailed overview of the research conducted by the authors on how teachers adapted to online teaching during the COVID-19 pandemic in Vietnam. The authors have provided evidence from semi-structured interviews with ten teachers within the Department of English at a university in Vietnam, which adds credibility to their findings. Furthermore, they have also provided an extensive literature review on previous studies related to this topic, which further strengthens their argument.

However, there are some potential biases in the article that should be noted. Firstly, the sample size used in this study is relatively small (ten participants), which may limit its generalizability to other contexts or settings. Secondly, all participants were from one university in Vietnam; thus, it is unclear whether these findings can be applied to other universities or countries. Additionally, there is no mention of any counterarguments or alternative perspectives on this issue; thus, it would be beneficial if these were explored further in future research. Finally, there is no discussion of possible risks associated with online teaching during a pandemic; thus, it would be useful if these were addressed in future studies as well.
