George Watson’s College is a mixed independent school and I have been using the TI-NspireTM NavigatorTM since October 2008 with most of my classes (students: 11-12 year olds following the compulsory secondary mathematics curriculum). In this lesson I used the File transfer, Screen Capture and Class Analysis features.
I thought that this lesson activity gave my students an opportunity to interpret mathematics by devising and describing in words the general relationships between angles. Some of the weaker students preferred to describe things in terms of the numbers shown on their diagram in its static form. However, as I was able to identify who these people were using Screen Capture, I was able to individually guide them towards trying to describe the relationship in more general terms using words, or angle labelling conventions, rather than just numbers.
Using Screen Capture enabled me to effectively target individual support to those in the class who needed it most.
