Scientists make claims all the time, but how do we know whether to trust these claims? This
is where CER comes into play. This system for verifying claims represents three main parts
of an argument, the claim (C) or in other words a one sentence answer to a research question,
evidence (E) measurements or observations that support the claim, and reasoning (R) an
explanation of why the evidence supports the claim.
Our first- and second-year Scientific High School students took on the task of reading a real
scientific article about bee stings and applying their knowledge of how to identify CER and
apply this method in order to verify validity of the claim in the article.
Come sapere se un'affermazione scientifica è vera oppure no? La risposta è nel metodo CER,
acronimo di Claim=affermazione, Evidence=prova e Reasoning=dimostrazione.
I nostri ragazzi della Prima e della Seconda classe del Liceo Scientifico hanno applicato tale
metodo per verificare la validità delle affermazioni contenute in un articolo scientifico sulle
punture d’ape!
