Exercise 3
This time we'll go all the way and evaluate a whole argument.
1.
Drag this map onto your workspace and evaluate the basis box first, then
the reason, then the position.
Drag this image onto the
workspace to proceed. You must be using the inbuilt
browser in Rationale 1.3 or later.
Hints
- Start with the basis box: Is this a reliable source of information?
(You already thought about this in set 6)
- Next look at the reason: what confidence do you have in it,
given your assessment of its
basis?
- If you think the basis is reliable, ask yourself: does this reason
give support for the position? How good a reason is it -
strong or weak?
- If you think the basis is a poor source of information ask yourself:
could I still reasonably accept this claim on other grounds? If
the answer is no, then the reason can't provide any support for the
position.
- Now evaluate the position: what confidence do you have in this?
If the reason doesn't support it, can you think of any other grounds for
accepting it?
- Reflect all these decisions on your map by selecting each box
in turn and using the 'evaluate' section of the ribbon to add icons to the
map
2. Check your work against the model.
