Critical Thinking for Students
In the second half the book moves on to assessing the strength of arguments, indentifying weaknesses such as ad hominem arguments as well as seeing how an argument can be strengthened. There is a chapter on assessing the credibility of evidence, and the book finished with a longer example of an argument to be analysed.
This is a short book, and I feel that it is possibly too short for those who want to develop their critical thinking skills. I would have liked to have seen more in the way of examples that those reading the book could relate to - for instance taking a typical essay on a topic and seeing how the arguments in it could be improved. But the book does have suggestions for further reading, and if you want a quick introduction to critical thinking then this book might suit you.
