PENERAPAN MODEL CREATIVE PROBLEM SOLVING PADA MATERI PERSAMAAN GARIS LURUS UNTUK MENINGKATKAN AKTIVITAS DAN PRESTASI BELAJAR SISWA SMPN 1 GANGGA

This study aims to improve the activity and learning achievement of VIII-4 grade studentsof SMPN 1 Gangga in learning straight line equation material for the 2019/2020 school year. Activitiesand student achievement in mathematics are very low, especially in grades VIII-4. For this reason,learning requires a learning model that can increase student creativity in solving problems so that it hasan impact on increasing student activity and learning achievement. One such model is the CreativeProblem Solving learning model. This Creative Problem Solving model is applied in this study toachieve the expected goals. This research is a classroom action research conducted in three cycles. Thedata analysis technique uses descriptive qualitative. The results obtained after applying the CreativeProblem Solving model were in the first cycle students 'activity scores 12 and 14 with an average scoreof 56.03 and completeness learning 48.28%, in the second cycle students' activity scores 16, 17 and 17with an average score of 61.59 and mastery learning 65.52%, and in cycle III the score of studentactivity 16 and 18 with an average score of 69.89 and mastery learning 86.21%. An increase in studentactivity scores at each meeting for each cycle. While the average score of student learning evaluationresults also increased in each cycle. Thus the Creative Problem Solving model increases the activityand learning achievement of students in class VIII-4 of SMPN 1 Gangga in learning straight lineequation material for the 2019/2020 school year.
