How to use these resources. The ALT3 resources are designed to encourage students to explore interdisciplinary topics and bring programming, design and algorithmic skills to bear on the creation of models. Examples of modelling a popluation growth based on a LC Geography question are given in Python and Javascript. Similarly a question from LC Physics/Construction Studies is modelled in Scratch. A simulation package explores the agent-based model and facilitates analysis of emergent behaviours. Teachers and students are encouraged to use these resources as platforms to create their own resources, as forms of assessment and in particular as reflection pieces for learning portfolios. The resources are designed specifically to be used by students to record artefacts and reflect on their learning, in particular html and pdf resources.
