ABSTRACT

The purpose of this research was to explore the diffrencess between  students’ chemistry achievement using M3PK  and students’ chemistry achievement using Traditional Model (Conventional). The population of the research is students grade XII of Senior High School 1 in Berastagi  consisted of 5 class. The sample is selected by using purposive sampling to choose two classes as experiment class and control class. Experiment class is taught by M3PK while control class taught by Traditional Model. Test instrument  validated before used by correlation moment product formula and  from 30  items taken 22 items were valid. And then, 20 items choosen as instrument test of research. The reliability of test  determined by using KR-20 formula and gotten the reliability of test is  0.781.   

The results showed that this model is very significant to increase the ability of students in learning chemistry, especially on the Colligative Properties of Solution as the select topic for this research. The statistical data of research showed that mean  of pretest in experiment class is (34.464  ± 8.535)  and  posttest is (86.25 ± 7.531). In control class, the mean of pretest is (35.535 ± 11.574) and posttest is (75.178 ± 8.973). Based on the hypothesis test at the significances level α = 0.05 showed that  t_count >  t_table (5.31 > 1.714) therefore Ho refused and Ha received.Thus, students’ chemistry achievement  taught by M3PK is higher than students’ chemistry achievement  taught by Traditional Model.
