Blue Coat School is a state secondary school for students aged 11-18 years in Walsall, UK.  This class have used the TI-NspireTM handhelds previously and this was the first time I had also used TI-NspireTM NavigatorTM with them. In this lesson I used Screen Capture.
The TI-NspireTM NavigatorTM Screen Capture view enabled students to communicate their findings and consider alternative solutions - some students’ curve families were larger/different to other students’ curve families. TI-NspireTM NavigatorTM gave me continual updates on the progress the class was making so that I could target interventions better. Also students could ‘see’ that other students were progressing in ways that were different to them.  Some students had clearly got screens that matched my hand-drawn diagram of a family of curves better than other students.  This made them aware that the possibility existed of solving the task (as others in the room had clearly done so)
