A new page on this blog is on Top Posts and Pages which I can see from the WordPress statistics has been a popular page itself this week.

Jane Hart, the founder of the Centre for Learning and Performance Technologies has for the last five years has been generating an annual “Top 100 Tools for Learning” list by asking learning professionals to share their favorite tools for learning.
The finalised list of the 2011 Top 100 Tools for learning from C4LPT (Centre for Learning and Performance Technologies) has now been published.
Looking at the list – as a teacher I use many of these tools; I thought I would outline here those tools in the list I use in my Mathematics teaching. Each link takes you directly to the site or to a post giving further examples of the use of that tool.
