Table 3. Response analysis of optional free-text questions from the post-survey highlighting several common themes.

Q19: Which parts of the educational module helped to facilitate your learning? Which aspects of this module did you like?

Pinyin in the module was one of the most helpful things from the module      -      “I liked the incorporation of pinyin into the module to help those of us who are fluent but have a more difficult time reading”      -     “Love the pinyin spelled out to block off certain words. Was very helpful to have it laid out to work through reading it for words I wasn't familiar with” Usefulness of the FAQ format and the keywords table:      -     “I think the FAQ style of the module was perfect”      -     “The key words table was very useful, since it allows me to string together my own sentences/ways to describe COVID19 vaccination”

Q20: Which areas of the educational module can be improved? Which aspects of this module did you not like? Feel free to share any thoughts or suggestions!

Incorporating audio guide to help with pronunciation:      -     “Embedding audio clips would also help in case people need pronunciation help”      -     “Would be helpful to have audio associated to hear the sentences” Adding traditional Chinese characters would be helpful:      -     “Perhaps add traditional characters as some communities use these more than simplified.” More interaction within the module would have facilitated learning:      -     “Could use an interactive component of the module to reinforce learning ”

Q21: Please use this space to share any thoughts/experiences you have about using Mandarin in your life and/or career!

Shared their experiences using Mandarin in their life and/or medical career and commented on the usefulness of the module:    -   “I think this is helpful for talking with friends and family and for providers who are fluent and certified to provide care in Mandarin, but I won't be able to use this information in my practice as it would lead to worse care for my patients. I definitely need to use a certified interpreter when giving this information to patients”    -   “I used to work in a Chinatown clinic, and felt that the questions/responses are quite relevant and came up frequently in doctor-patient interactions.”    -   “Super helpful guide, I've come across these questions from my family and struggled to relay this information correctly in Chinese”
