PENERAPAN PENDEKATAN CTL DALAM E-LEARNING BERBASIS WEBLOG TERHADAP PENINGKATAN HASIL BELAJAR SISWA PADA POKOK BAHASAN LAJU REAKSI

The purpose of this research is to know whether the increasing of student learning outcomes and student learning activity which is in teaching of CTL approaching implementation by e-learning based on weblog is higher than increasing of student learning outcomes which is in teaching of CTL approaching implementation without e-learning based on weblog towards the reaction rate chapter. The population in this research is all the students of XI IPA MAN 1 Medan which consist of 6 classes with amount 240 students. By using purposive sampling technique with amount 2 classes, they are Experiment Class I that given CTL approaching implementation teaching by e-learning based on weblog, and Experiment Class II that given CTL approaching implementation teaching without e-learning based on weblog. Based on the data obtained, the average of chemistry learning outcomes in Experiment Class I is 0.750, it is higher than Experiment Class II that is 0.546. The increasing of chemistry learning outcomes in Experiment Class I is 75% while in Experiment Class II is 54.6% with differences 20.4%. Both experiment classes were tested with t-test in right side and gained the increasing of learning outcomes with tstatistics > ttable (10.605 > 1.667) and learning activity value was tstatistics > ttable (6,324 > 1,667), it means the increasing of student learning outcomes and learning activity which is in teaching of CTL approaching implementation by e-learning based on weblog is higher than student learning activity which is in teaching of CTL approaching implementation without e-learning based on weblog towards the reaction rate chapter.
