Abstract

Bq.Patma Sari (2018).The Influence of Group Invetigation Method on Problem Solving Ability Student Class VIII SMP Negeri 5 Masbagik Academic Year 2017 / 2018. Thesis, Biology Education Study Program, Hamzanwadi Selong University. Counselor I : Dra. Hj. Hartini Haritani M.Pd Supervisor II : Nurul Fajri M.Pd This study aims to determine the effect of Group invetigation methods on students' problem solving skills on Plant Life System materials in grade VIII SPM Negeri 5 Masbagik students of the academic year 2017 / 2018. This research type is quasi experiment. The research population is all students of class VIII consisting of 150 students and divided into 5 classes. Of the 5 classes of population is class VIII B as an experimental class with the number of students 25 people and class VIII C as a control class with the number of students 25 people. data collection instruments used are pretest and posttest. For data prerequisite test is done by data normality test by using chi-square formula and homogeneity test of data by using F-test formula, while hypothesis test technique use t-test formula. Based on the results of research and calculation results can be seen student learning outcomes in the experimental class included in the category high with an average score of 76.16 and student learning outcomes control class included in the category with an average value of 63.7. From result of t test which have been done diproleh t= 5,398, where tt with dk = 50, and significant level 0.05 for test of two side = 2,021. it thit> ttab or 5.398> 2.021. Thus it can be concluded that there is influence of Group Investigation study method to solve student learning problem. Keywords: Group Investigation Method, Troubleshooting
