Hints
- First evaluate the basis box. Ask yourself: what support does this basis give the
reason?
Stephen Hawking is a respected expert speaking in his field of study: is
it reasonable to trust him?
- Now evaluate the reason. Ask yourself: What confidence should I have in this reason, given my
assessment of its basis?
- If you think the basis is reliable, ask yourself: how strong a
reason is this for the position above it? 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?
- Click on the reason, go to the go to the 'Evaluate' section of the
ribbon and click the box that reflects your assessment
- Finally evaluate the position: what confidence do you have in it, given the degree of support
the reason provides?
- Make sure you've put evaluation icons in all boxes
2. Check your work against the
