THE IMPLEMENTATION OF CONTEXTUAL TEACHING AND LEARNING USING CONCEPT MAP ON THE TEACHING ACID BASE TOPIC

This thesis purposes the implementation of Contextual Teaching and Learning using concept map on the teaching acid base topic. The objectives of research are todetermine the difference of student’soutcomes in acid base topic by CTL using concept map compared to conventional model andto determine the influence the student’s outcome of CTL using concept map in learning acid base topic.The population of this research wereallof students in gradeXI,2nd semesterand academic year 2015/2016 in Indonesia.The samples are 2 classes from student in SMA N 11 Medan by purposive random sampling method. Theexperimental class is learned by CTL using concept map and control class is learned by conventional model. The instruments are using multiple choice test to see the student’s outcome. The instrument of research is standardized by expert validator and empiric validity. Data analysis is using manual calculation. The result of test is standardized and there are 21 items valid with reliability is 0.90474. The result data shows that the student’s outcome taught by CTL using concept map give higher significant difference than taught by conventional model. It can be seen from the average of gain and also proved with z-test, the normalized gain in experimental class (0.6388±0.1495) and control class (0.1958±0.1269). The statement support the research data result of hypothesis test is zcount = 14.2995 and ztable = 1.645. The calculation shows that Ha is received or H0 is rejected. Ha is student’s outcomes through Contextual Teaching and Learning used concept map media is higher than using conventional method in acid base topic, and H0 is student’s outcomes through Contextual Teaching and Learningused concept map media is less than using conventional method in acid base topic.
