This study was conducted to determine the differences in student learning outcomes based on the low student learning outcomes which are below the KKM value ≥ 70 and aimed at knowing the magnitude of the influence of the use of cooperative models Student Teams Achievement Division (STAD) with those taught using conventional models of class X class 10 Pontianak SMA on the material of the atomic structure sub protons, neutrons, electrons and isotopes, isobar, isoton. The form of the research used was quasi-experimental research with a pretest-posttest design control group research design. The sample in this study was class XA students as the control class and XB as the experimental class. The data collection technique used was a measurement technique. Data collection tools used were interviews and test results of student learning in the form of essays. The results of statistical tests using the Mann Whitney U-test with α = 5% obtained a probability of <0.05, which meanth that Ho was rejected. These results indicated that there were significant differences between the learning outcomes of class X students of Pontianak State Senior High School on the material of atomic structure sub proton, neutron, electron and isotope, isobar, isoton. The magnitude of the influence of the use of the cooperative model Student Teams Achievement Division (STAD) on the atomic structure material of protons, neutrons, electrons and isotopes, isobars, isotons on student learning outcomes calculated by Effect Size was 0.431 which is categorized as medium. This showed that the use of the cooperative model Student Teams Achievement Division (STAD) type had a categorical influence on the learning outcomes of class X students of SMA Negeri 10 Pontianak on the material of atomic structure sub proton, neutron, electron and isotope, isobar, isoton.

ABSTRACT The process of learning chemistry which only focused on teacher as informant caused the students’ memory lower. This could make the students’ learning outcomes lower, thus, it was needed STAD type of Cooperative Learning Method which had the process of interaction between student and teacher, and could help the students comprehend the material. Therefore, it was necessary to make a research which had the purpose to know the difference between students’ learning outcomes and memory which used STAD type ofCooperative Learning Method and lectures teaching method as well as how large the effect of STAD type of Cooperative Learning Method on salt hydrolysis material was. This research was Quasi Experimental Nonequivalent Control Group Design. The sample of the research was choosen by using saturated sampling which XI IPA 1 as experimental class and XI IPA 2 as control class. The techniques of data collection used measurement technique, observation, and interview while the tools of data collection used tests such as essayquestion, observation sheet, and interview guide. The statistical analysis of posttest result using U-man whitney test obtained significant value 0.000. This value was smaller than α (0.005) which meant that there was difference in learning outcome between experimental and control class. The statistical analysis result of U-man whitney delayed test obtained significant value 0.006, this value was smaller than α (0.005) which meant that there was difference between students’ memory in experimental and control class. The calculation of effect size showed value 1.64 with high criteria which gave high effect on students’ learning outcomes which was 44.95%, while the calculation of students’ memory effect size showed value 0.69 with moderate criteria which gave effect on students’ memory which was 26,42%.

The background of this research is lack of student’s learning to the tenth grade students of SMA Adisucipto Sungai Raya, due to the less of student’s comprehension especially about concept of compound hydrocarbon system. Therefore, it was needed the method of learning to increase the student’s comprehension about appropriate concept with characteristic both of the subject and student. The aim of this research was to know the differences of student’s learning and the increasement of student’s learning by using cooperative learning method type RTE in chapter of compound hydrocarbon system with couple card. The kind of this research was Pre-Experimental one group pre-test and post-test design research with subjects of this research were thirteen students from grade XI IPA of SMA Adisucipto Sungai Raya. The technique and the instrument to collect the data was using student’s learning test, observation, and interview. The result of data analysis showed the mean score of pre-test was 27,21 and the mean score of post-test was 75,86. The statistic result of Wilcoxon showed that the score was 0,01 less than α (0,01 < 0,05) that mean there were the differences of student’s learning and the influence of student’s learning by using cooperative learning method type RTE with couple card. The increasement of student’s learning was known by counting the gain score of 0,66 in medium score categorize. In this case, the cooperative learning method type RTE with couple card can be used in chapter of compound hydrocarbon system to increase the student’s learning.Keywords: Couple Card, Rotating Trio Exchange (RTE), Compound Hydrocarbon System
