PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING PADA SUB MATERI TATA NAMA SENYAWA HIDROKARBON TERHADAP HASIL BELAJAR SISWA KELAS XI MIA SMA NEGERI 1 PEMANGKAT

Abstract

The Minimum Exhaustiveness Criteria (KKM) of eleventh grade students of  SMA Negeri 1 Pemangkat on chemistry subject was still under 75, especially on the material about  hydrocarbon  compounds  and  petroleum  with  a  percentage  of  70.53.  Thus,  by using  an  appropriate  learning  models  could  improve  students’  achievement.  The purpose of this research was to know whether there was a difference and the influence of the  PBL learning model against student  learning  outcomes.  This  was  a  Quasi Experimental  Research  with  Non-equivalent  Control  Group  Design.  Sample  selected by using purposive sampling, they were XI MIA-3 students as the class experiment and XI  MIA-2  as  class  control.  The  techniques  of  data  collection  were  measurement, observation, and direct communication technique. The tools of data collection were test results learning, observation sheets, and interview guidelines. Based on data analysis using  non-parametric  test  of  U-Mann  Whitney  showed  that  there  was  differences  of learning  result,  that  was  0,000  <0,05.  This  showed  that  students'  learning  outcomes was  different  between  different  experimental  class  with  control  class.  The  effect  size obtained by the student learning result was 1.19 which is included in the high criterion. Keywords:  Learning  outcomes, Problem  Based  Learning (PBL),  hydrocarbon compounds
