ab: Summary: If educators want to interest students in mathematics (and
science), they must engage them in the lower forms of high school or
even earlier. So, teachers should always consider a topic’s ability
to interest students in the early years of instruction in high school
and its topicality. Networks have come into prominence recently with an
episode of Four Corners on ABC and the popular film, The Social Network
so discussion of the program or the film and even a viewing of one or
two scenes, along with discussion of aspects of social networking such
as Facebook and Twitter, are a good way to introduce the topic. Graphs
are representations of networks and it makes sense to teach them
together. Also, teaching them together can be an interesting example of
applied mathematics and how mathematicians and scientists work together
collaboratively when applying mathematics and developing a new
scientific theory. It is a good way of teaching mathematics in context.
The topic is also relevant to the new Australian curriculum re graphs
and graph theory and it provides an excellent opportunity to “embed
digital technologies so that they are not seen as optional tools”.
This article shows how graphs and networks can be introduced in Years 7
to 10 in a variety of ways depending on: students’ interests, their
preoccupation with the Internet, game playing and social networking
sites such as Facebook, and teachers’ co-operation with physics,
science, or even, drama teachers. It shows how a good documentary on
the subject with an intriguing title ‒ “How Kevin Bacon Cured
Cancer” ‒ can also be extremely useful. (ERIC)
