Abstract: Based on Marzano’s taxonomy of educational objectives，the two-dimensional framework of physics problems is built. This framework has two domains of knowledge ( information and mental procedures) as one dimension and cognitive process ( retrieval， comprehension， analysis and knowledge utilization ) as another dimension. According to the dynamic relationship between the two dimensions，physics problems designed from the low level to high level in cognitive process and from information to mental procedures are classified into 4 levels and 13 sublevels with specific examples offered.

Key words: Marzano’s taxonomy of educational objectives, knowledge domain, cognitive process, physics problems design
