Abstract

The aims of this study are to determine differences in mastery effective sentence students who are taught using GABI of students using conventional media and the effectiveness of GABI. This study used a quasi-experimental research methods pretest-posttest control group design. Determination of the sample using cluster random sampling (random sample based cluster ) to determine the class. Based on the results of the lottery accounting program as control class and nursery program as a experiment class. The validity of the instrument in the form of construct validity. Reliability of the instrument is calculated by reliability rating technique.The test results showed that the prerequisite analysis and posttest-pretest scores were normally distributed and homogeneous. Based on t-test analysis of data mastery effective sentence posttest control group and the experimental group, obtained t count of 3.17, p equal to 0.002 (p <0.05 ). These results suggest that there are significant differences between students using GABI and students who received learning by conventional media in Unikal. Based on the results of t-test and an increase in the mean scores of control and experimental groups, obtained by t count 4.40, p equal to 0.000 (p <0.05 ), an increase in the control group mean score of 0.81 while the experimental group mean score increases by 4, 03. Based on the difference in mean score increase in the experimental group were higher than the control group, indicating that GABI more effective than power point as conventional media.
