The Effect of Applying Discovery Learning Model on The Students’ Speaking Achievement

Abstract

This research aimed to describe the Effect of Applying Discovery Learning Model on The Students‟ Speaking Achievement. The objective of this research was to find out whether Discovery Learning Model significantly effect the students‟ speaking achievement. The population of the research was the X grade students at SMK PAB 8 Sampali of the academic year 2017/2018, which consist of 177 students and 70 students took as the sample. By using cluster random sampling technique class X BM-2 and X TKJ-3 was choosen as the sample. The design utilized two different classes as the sample of the research. One of the classes was assigned to be experimental group and the other control group. The experimental group given treatment by applying Discovery Learning Model and control group by using Lecturing Method. The instrument of the research was speaking test. The test given to students aimed to collecting the data supporting the students‟ speaking achievement. The t-observed formula was implemented to find out the ttable value of both groups as the basic instrument to test hyphotesis of this research. After analyzing the data, the findings showed that the value of tobserve was higher than ttable (5.327 > 1.995) with df = n-2 (70-2 = 68 and α = 0.05 %). It means the alternative hyphotesis (Ha) was accepted and (Ho) was rejected, there were significance effect of applying Discovery Learning Model on the students‟ speaking achievement. The influenced of this model was 98,74% and 1,26% by other factors.
