Preliminary study results showed that in
general, problem-solving capabilities and the state
SCHOOL of Samarinda Metakognisi still low.
Therefore, researchers developed a learning model
capable of improving problem-solving skills and
metacognition. The purpose of this research is to obtain
the feasibility of components and measuring
instruments reliability. Data validation results are
obtained through Focus Group Discussion by three
experts in the field of physics and education.
Metacognition Physics Learning model developed needs
to be validated by experts through Focus Group
discussions. The expert validation results of the MI-
PML model book components are valid and the
instruments used are reliable. MI-PML can be
implemented in learning to improve problem-solving
skills and Metakognisi.
Keywords : Content Validity; Construct Validity; and PML Model.
