Research as wide as possible since we want to give the others wide enough knowledge about our topics. You don’t need to dive too deep, a surface knowledge is enough for this presentation, at least to the extent the audiences know what they’re learning and what to do if they want to dive deeper. Please put in the data that you have researched in this notion, make it as tidy as possible, so it’s easier to read the materials.
Don’t interrupt the research result that other has put in. If you think there is something wrong or can be improved, please talk to the person in charge of the topic first. After you get the permission, you may change or ask the person in charge of the topic to change it.
