Abstract
The aim of this research was to obtain about vocation students physics problem solving skills, increasing as the effect of modeling instruction applied in physics learning. Quasi experiment method was used with the randomized control group pretest postest design. The research was conducted on the students in grade X at one of vocation school in Pekanbaru city that was choice with random sampling technique. An experimental class and one controller class selected with 33 students both of them. Experiment class gets modelling instruction treatment, while control class only gets conventional model. Problem solving skills data was collected by using problem solving skills test instrument in the essay. The result showed that applying modeling instruction in physics learning can increasing physics problem solving skills than conventional model with experiment class N-Gain (0,58) is greater than control class N-Gain (0,32). Consequently, it was concluded that applying of modeling instruction in direct current circuit learning is more effective for increasing physics problem solving skills than conventional models.
