THE INFLUENCE OF CONCEPT ATTAINMENT LEARNING MODEL ON STUDENTS ACHIEVEMENT IN STATIC FLUID TOPIC OF CLASS XI SMAN 3 SIANTAR ACADEMIC YEAR 2015/2016

The objectives of this research are: (1) Student’s achievement by using Conventional Learning. (2) Student’s achievement by using Concept Attainment Learning Model. (3)The influence of Concept Attainment Learning Model on student’s achievement.
The type of research is quasi experimental research. The population is all students of class XI IPA SMAN 3 Siantar Academic Year 2015/2016, consist of 6 classes. Two classes selected randomly as sample. One class as experiment class and another class as control class. Eksperiment class using Concept Attainment learning model and control class using conventional. Research data collected through Concept Attainment learning model and Conventional test in multiple choice. The test given twice before and after treatment (pretest and postest). To test the hypothesis using t test, but previously must tested the normality and homogeneity of the data.
From the analysis of postest data in experiment class, for Concept Attainment obtained the average score is 83.59. The testing criteria is accept H0 if ttable between -1.67 and 1.67, and rejected H0 if t has the other score. From the calculation result of concept attaiment obtained tcount = 3.79, so H0 is rejected and Ha is accepted or in other word said that there are significant influence between Concept Attainment learning model and Conventional learning model on student’s learning achievement
