Abstract: Knowledge of the
environment is one of the first-year course that must be taken by students
of Biology Education Program in STKIP
Hamzanwadi Selong. So far, the knowledge of the environment course was
conducted using conventional methods that did not train students' critical

were in unistructural stage and 1.34% at
the multistructural stage. Based on the data obtained, it is known the critical thinking skills have
