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.
