Explanation:
Direct characterization is when the author specifically tells the reader the traits of a character. In this excerpt, Dickens tells you that the woman is elderly, wise, experienced and knows what is "good for children".

The reader would then be lead to develop his own conclusion about the whether or not the woman was wise and experienced.
