Professional Learning Communities (PLC)

3

Teacher lead with support from PDST.

“None of us is as smart as all of us” - Japanese Proverb

Evening sessions (Face to face/online).

Long-term support network.

Teachers support each other in the development of knowledge, teaching and learning approaches etc.

Mathematical Modelling Cycle

5

Mathematical modelling is the unifying strand through which teaching, learning and assessment take place.

It is a process that will develop skills such as:

• Formulating problems

• Translating problems into mathematics

• Computing solutions

• Evaluating solutions

GROUPWORK - CREATING MATHEMATICAL MODELLING PROBLEMS

Our goal is to carefully remove some scaffolding (data) from a word problem, to enable us to redesign the task and use it as a mathematical modelling problem.

How could we rewrite this so that it becomes a mathematical modelling problem for our students?

The diagram below shows distances in metres between different various points. We would like to remove scaffolding to enable

the student to engage with the problem. We wish the students to:

Find a minimum spanning tree for the network in the diagram below, showing clearly the order in which you selected the arcs for

your tree, using

(i) Kruskal’s algorithm

(ii) Prim’s algorithm, starting from A

The table below shows the distance, in metres, between shops in an outlet centre to

consider when physically connecting each shop for Gas supply.

(a) Create the network using the direct connections and distances outlined in the table.

(b) Using Prim's algorithm, starting from A, determine the minimum spanning tree so that

all of the shops are connected and find the total weight.

Task: Redesign this question to become a modelling problem where students need to formulate the problem, may have to research information, make assumptions and possibly do further iterations.
