Data sharing

I have been looking for a way to gather and share data about the use of electricity. The purpose is to provide a data set for classes studying electrical energy to use, either for interpreting and graphing activities or for comparing with calculated estimates..

I spent a while going through a few possibilities, including a google site, a blog and a wiki. In the end, the easiest and clearest presentation seems to be just to publish a google doc with the data in. This is simple and clean for me and gives direct and transparent access to the data.

Seems obvious really now that I think about it. Sometimes it seems I try and make things more complicated than they need to be.

Here is the html display for sharing.

I have also been putting some more questions on to Quia. This time I have been adding IBSL Physics questions. I have learned here that thinking through the choice of labels is important. I used some for IGCSE (e.g. mechanics) that overlap with the IB ones so that they can get mixed up in quizzes. I have now started using labels like ‘IBSL_Mechanics”. Overall this seems to be a useful addition to the resources and a good way of leveraging the past paper questions for the students. If I could think of a way of doing paper 2 questions, that would be great.
