PENINGKATAN PRESTASI BELAJAR MATERI BILANGAN BERPANGKAT MELALUI MODEL DISCOVERY LEARNING

Abstract

This research is motivated by the unoptimally mastery of material exponential number among learners at grade IX A State of Junior High School One Cawas Klaten second semester of academic year 2014/2015. This study aimed to describe the optimization of mastery of the exponential number through Discovery learning approach in learning of mathematic. Subject and source of research data is a total of 32 learners. Methods of data collection using observation, documentation, and testing. Analysis of data using a critical and comparative analysis. Indicators of success using the criteria limit minimal is 80 and the target class completeness 100%. Research procedure uses cycles. From the results of research and discussion, it is known there is a progess in achievement from pre cycle until the second cycle, the pre cycle average of 77 and the cycle I average of 83 and the second cycle by an average of 92. The percentage of mastery learning from pre cycle obtained by 34% and the first cycle was obtained by 66% and the second cycle of 100%. Thus, the learning achievements of learners in mathematics learning with the exponential number of pre cycle material to the second cycle brought a significant rise.
