Abstract

The aim of this research is to know the effectiveness of laboratory experiment method to increase students achievement, students activities and the significance correlation between students achievement and students activity. Population of this rearch are all of students in grade XI at 2nd semester from SMA Negeri 1 Lubukpakam, SMA Negeri 3 Medan, and SMA Swasta Methodist 1 Medan. Sample was choosen by purposive random sampling and taken 2 class for each school. The students were divided into two groups, one as experimental class and other as control class. Research design in this study using Quasy experimental design. The Instrument test that was used in the form of 20 multiple choice as achievement test and non-test in list of activity form. In experimental class was used laboratory experiment method and in control was used conventional method. After conducting research, have gotten the result in experimental class the average of % gain is 80.00 ± 6.71 and in control class 63.00 ± 7.00. The hypothesis testing by using right side t-test. Criterion of hypothesis is received Ha if the value of tcount > ttabel . From the calculation of hypothesis testing for students achievement obtained the value of tcount is 15.591 where ttabel = 1.288. It means that tcount ( 15.591) > ttabel (1.288) so it means (Ha) is accepted and (Ho) is rejected. It proved that the mean of students achievement that taught using laboratory experiment method is higher than conventional method. Also hypothesis testing for students learning activities obtained result tcount= 5.633 while ttabel = 1.288, it means that tcount > ttabel so it means accepted (Ha) and rejected (Ho). It means the mean of students learning activity that taught using laboratory experiment method is higher than conventional method. The result of correlation calculation between students activities and students achievement obtained low correlation and positive in experimental class where obtained rcount = 0.264. The % effectiveness of applying laboratory experiment method to increase students achievement in experiment class is 23.33 % while the % effectiveness to increase students learning activity in experiment class is 18 %.
