Abstract: This study investigated the standards adopted by college students to prove their claims after laboratory experiments. There are two kinds of reasons in the current literature, namely, empirical consistency and claimed rationality, but the laboratory observation of third-year college students shows that the third kind of reason, namely observation reliability, is needed. This hypothesis is further verified by analyzing the warrants written by undergraduates to prove the claims formed after laboratory experiments. Three students & apos; The proof criteria are determined, that is, the consistency of experience, the rationality of claim and the reliability of observation. The most common criterion is to prove the rationality of the claim of good results and the observational reliability of bad results.Moreover, multiple justification, which means more than one attempt being made to justify a given claim, was also found. It reveals that multiple justification, rather than single justification, is suitable for students to make scientifically acceptable claims. The implications and suggestions of this study are also discussed.
