Development of student worksheet based curious note program (cnp) learning model to improve science process skills of senior high school students grade xi in chapter equilibrium and rotational dynamics

This research aims were to: (1) produce Curious Note Program worksheet and (2) know science process skills improvement. This was a development research by using 4D models (define, design, develop, and disseminate). The development product was tested in grade XI MAN Yogyakarta 2, 26 students for limited test and 55 students for field test. The research results: (1) worksheet based CNP learning model developed for teaching physics in the chapter Equilibrium and Rotational Dynamics in order to improve science process skills of senior high school students grade XI, from the CVI score of validation result of 0.83 (very good) and the approval rate of 93.90% (reliabel). Almost students agreed to the worksheet with CVI score of 0.33 (very good) for limited test and CVI score of 0.31 (very good) for field test. (2) Science process skill improvement for limited test with presentation 13.84% and standard gain of 0.16 which is included in low category. Science process skill improvement for field test with presentation 14.58% and standard gain of 0.18 which is included in low category.
