1 |
Write about aspects of the workings of a simple spreadsheet or simulation. | 0 1 2 |
U |
|
2 |
Use
IT-based models or simulations to investigate given
options. Write about the consequences of the different decisions made such as changing the data. |
3 4 |
G |
|
3 |
Use
an IT based model or simulation to help make own
decisions. Write about the consequences of more than one change of data. |
5 6 |
F |
|
4 |
Use
a computer model or simulation to detect patterns
and relationships - relating more than one change
made to the output produced. Understand the rules governing the model such as the action of formulae. Make simple predictions |
7 8 |
E |
|
5 |
Explore
the effects of changing the variables
within a computer model or simulation - printouts showing
changes with the effects clearly identified and explained. Make simple predictions about some of the possible effects. |

D |

6 |
Use
at least two computer models of increasing
complexity. Vary the rules within a model or simulation, such as changing a formula. Show some assessment of the validity of the model by describing how well it represents the situation by comparing its behaviour with other data. |

7 |
Design,
construct and use own computer model of a situation to
meet identified needs (which can be supplied). Evidence showing development of each stage and printouts including formulae. |
14 15 16 |
B | |
8 |
Based
upon an initial appraisal of the key features of
the software, design, construct and use a
computer model to represent a situation or process. Document ease of use, limitations and suitability of software for purpose. |
