I made a survey that was composed of about 25 questions ranging from, "Can you login to Gmail?" all the way to, "Can you video chat using Gmail?" It took me about an hour to make, and I used a three point Likert scale to get the best range of answers. I don't know if the options I chose for the answers were the best, but I didn't see any confused comments. So, I am assuming everyone did ok with it.
I sent the survey out this Monday and asked people to complete it before the end of the day (my professional time was on Wednesday). The results I received were really interesting. All people could login, but there were major discrepancies with the calendar, drive, and more complex features of gmail. The ability levels of the staff are varied. So, I was faced with the age old question in teaching a group of people with varying abilities anything, which is, "HOW DO I DIFFERENTIATE?!?!"
Don't worry. I figured it out. I created a sign up sheet for people who wanted to meet and needed help. I had 10 minute time slots with anyone who wanted to meet. People had to enter in two topics they wanted to cover with me, and I came to them. Everything went really well, and I had a number of people say that they were really happy to have one-on-one help.
Overall, I feel like the approach I have taken, thus far, has worked quite well. The only challenge I will have in the future is how to best enhance the use of Google Apps by those people who are more advanced users.
