Lack of pedagogical content knowledge in questioning skills and how they were observed, lack of cooperation and not diversified teaching methods that can stimulate the cognitive, psychomotor and affective domains in students, making all of these gaps in the research literature. Thus, the researchers makes the development and validation of instruments for identifying Mathematics teachers perception about knowledge, simulation models, clinical observation and synergy (2P2S) in Professional

The population is consist of primary and secondary schools in three districts as known Beluran, Telupid and Sandakan, in the such eastern part of Sabah. The samples were the 30 primary Mathematics teachers who were non randomly and purposive selected who have been teaching at least more than 1 year. In mix methods, researchers can analyzed and used the model IDCV which contains 10 detailed and interactive phases to develop quantitative instrument optimally. The revised 2P2S instrument validation phase of quantitative analysis involves Rasch measurement model. This instrument has good person reliability at 0.90 and an excellent item realibility at 0.92. This instrument has a Standard Error of Measurement (SE) which is low, ± 0.19 logit. Both Infit MNSQ and the z-std are close to ideal value of 1 and 0 [(Infit MNSQ Person = 0.97; z-std =-0.1), (Infit MNSQ Item = 0.98; z-std = 0.0)] which is you can imagine the suitability of instruments to measure what should be measured based on the underlying theorems.
