Pengaruh Model Pembelajaran Berbasis Masalah Berbantuan Mobile Pocket Book Fisika Terhadap Kemampuan Pemecahan Masalah Peserta Didik

Abstrak

This study aims to determine the effect of problem-based learning models assisted by pocket book physics on problem-solving abilities. The type of research used was quasi-experimental design with pretest-posttest control group design. The population in this study were all students of class X MIPA Senior High School in Mataram. The research sample was taken using cluster random sampling technique, so that the selected students of class X MIPA five were 31 people as the experimental class and the X class MIPA six as many as 27 people as the control class. The experimental class was treated in the form of a problem-based learning model assisted by pocket book physics mobile and the control class was treated in the form of conventional learning. The instrument used to measure problem solving ability is a test instrument in the form of a descriptive test of five items. The research hypothesis was tested using the t-test with a significance level of 5%. The t-test produces a t-count value of problem solving ability of 5.832 which is smaller than àwhich is equal to 2.003 so that H₀ is rejected and H_a is accepted. So it can be concluded that there is the influence of the problem-based learning model assisted by pocket book physics on students' problem solving abilities. This result can be proven by the N-gain test, where there is an increase in problem solving abilities of 60% for the experimental class and the control class by 34% with the medium category.
