This unit starts with assumption that students are better at ICT than teachers, and that the teachers at your school need help. Students work individually but collaboratively to learn about various aspects of the Mac (both hardware and software). This information is then used to populate a pre-structured wiki, essentially creating an online manual for others to use. At the end of the unit, students need to work with a partner to line up a two-on-one session where they help a teacher to improve their ICT skills by using the wiki. I recently ran this unit simultaneously with 60 11-12 year old Y7 students, and they adapted to the collaborative nature of the wiki fantastically. At the end of the unit, when they had all taught their teachers, I received excellent feedback on their performance from my colleagues. It also got them really thinking and talking about the computers they use every day, and what they can do with them.
The material below should be all that you need to deliver this unit at your school:
