The Application of Discovery Method and Expository Method on The Powers of Number towards The Result of Student Learning in The Grade IX Junior High School of Perintis 1 Sepatan Tangerang

Abstract

Main reason of the low-quality education in Indonesia is caused by the application of learning method which has been trapped with the traditional mindset for ages. The fact, the traditional learning method cannot be implemented for all students because every student has their own uniqueness in power, need, and interest for studying. Therefore, the implementation of Discovery Method and Expository Method is expected that can effectively fulfill the student need and encourage student to be more motivated, participated and involved in learning process. This research aims to give better result on math learning. The used sampling is Cluster Random Sampling. Based on the calculation is obtained data that the average of student learning result through Discovery Method has mean 83.07, standard deviation 7.24, median 82.63 and modus 82.00. Further, the average of student learning result through Expository Method has mean 74.32, standard deviation 7.13, median 74.50 and modus 81.00. Based on t-test is obtained the value of tcount = 4.56 > ttable = 2.0063. Therefore, it is concluded that H1 is accepted and H0 is rejected. The conclusion of this research is that there is a difference in student math learning result on the powers of number taught using Discovery Method and Expository Method in the grade IX Junior High School of Perintis 1 Sepatan Tangerang.
