Evaluative reasoning skills enable us to assess the credibility of sources of information and the claims they make.  And, we use these skills to determine the strength or weakness of arguments.  Applying evaluation skills we can judge the quality of analyses, interpretations, explanations, inferences, options, opinions, beliefs, ideas, proposals, and decisions.  Strong explanation skills can support high quality evaluation by providing the evidence, reasons, methods, criteria, or assumptions behind the claims made and the conclusions reached.
