Some tips for group work

1. Create a shared GoogleDrive folder.
2. Make sure each and every person in your group is assigned a particular role.
3. Set deadlines for yourselves and stick to them!
4. Remember the critical, analytical approach: don't just list things, but be critical of your sources and remember to address the problems & relevant issues related to your topic.
5. Make sure all the pictures, videos etc. etc. extra material supports your work - don't add something just because it looks nice!
6. In the case of videos & voiceover: practice, practice & practice your spoken parts! Remember sentence rhythm, strategic pauses and breaks (to emphasize/mark something important) and general flow of the speech.
