Technology is a key part of driving student learning forward here in this Mexican lesson. The teacher is exploring with the class how quadratic functions vary, and uses a range of examples to illustrate patterns. In particular, she turns to technology to respond to the questions and doubts that the students express. The teacher uses technology to provide examples that can clarify and deepen students’ understanding and lead them towards developing some generalisations.

This is a rural, public school. Watch out for how the teacher:
- Analyses in detail each graph with students

- Uses technology to show differences between graphs

- Connects the graphs with their previous learning

How do use technology in your own classroom?
